Managing Losses in Compressed Air Systems with Thermal Mass Flow Technology

Managing Losses in Compressed Air Systems with Thermal Mass Flow Technology

Monitoring Compressed air within a manufacturing facility has become increasingly important as the associated costs have risen dramatically in recent years

Compressed air systems are found throughout industry and are often the largest excess user of electricity in a manufacturing plant. Air leaks can be a significant source of wasted energy and can be diagnosed by fitting thermal mass flow meters at strategic points in the system to calculate outflow generated air with downstream usage. Thermal Mass flow meters measure true mass flow which compensates for any differential pressures across the system, providing accurate comparative data from the installed locations.

The primary reason thermal mass flow meters are popular in industrial compressed air applications is the way they are designed and built. They feature no moving parts in a nearly unobstructed straight through flow path, require no additional temperature or pressure corrections and retain accuracy over a wide range of flow rates. Straight pipe runs can be reduced by using conditioning elements and installation is very simple with inline and insertion models available

 

 

 

 

 

 

 

 

 

 

 

TGF200

TGF200 series micro flow meters offer a low cost solution for accurately measuring compressed air based on patented sensor filming technology and advanced thermal mass flow measurement technology. This range is designed to measure pressure and temperature compensated mass and standard volumetric flow within small pipe-lines in general industrial applications and laboratories, offering high turn-down and a choice of outputs

TGF450

TGF450 Thermal mass flow meter was designed especially for the measurement of compressed air in larger pipes. It can provide stable and accurate measurement at a very economical cost and has 1.5% FS+0.5RD accuracy on a 100:1 wide turndown ratio. The compact design and thick probe are easily installed in high pressure pipelines with limited space. Manufactured from stainless steel, this insertion style flow meter has various power, signal output and mounting options

The fact of the matter is that compressed air is not cheap and is becoming a financial burden to both small and large companies operating expenditures. In this age of energy efficiency and widespread efforts to drive down associated costs in order to ensure a greener footprint, it is becoming more important for a business to identify why is it so important to monitor the air flow rate in compressors?

There have been extensive studies done over the years on plant wide operating costs for the majority of Industrial businesses and one of the largest fixed overheads continues to be electricity. One of the major contributors to this excessive electricity draw in a large number of instances are the company’s air compressors. The simple actions required to reduce excess electricity usage and provide for a more efficient compressor throughput is to monitor the air flow rates and optimize the compressor’s efficiency or else replace any parts in a compressed air system as highlighted during this monitoring.

Squirrel 2020

Modern Thermal Mass Flow meters such as those above can be integrated into Data logging packages such as the Squirrel 2020 via their analogue, digital or serial outputs. Time-base relevant data can then be evaluated to indicate problems with factory shift performance or individual operator technique. Installed flow meters can then also be used for allocating inter-departmental energy costs and managing budgets based on energy saving performance

Is your Flow meter delivering its best?

Is your Flow meter delivering its best?
Read on to discover how to extract the most from it!

 

 

 

 

From Guest Blogger, Edward Simpson of company RS Calibration

Any instrument deteriorates over time. It is a given that to extract the most from it, regular inspection, instrument calibration or an upgrade is mandatory to ensure that the instrument keeps on delivering its best. A flow meter is also one such equipment which is used for diverse applications in numerous fields from agriculture to aerospace. To ensure that such critical equipment consistently delivers its best, it’s important to know the indicators which help you determine whether it’s time for an upgrade or a new purchase.

The parameters listed below can help you decide whether it’s the right time to upgrade your flow meter or not:

♦ If there is a new development or extension in the current operations within the business, or even a small change in the layout of the existing arrangement of the equipment.

♦ Introduction of new piping networks which can alter the fluid dynamics and various compositions of the fluid contents are some of the factors which can affect the monitoring equipment.

♦ Any alterations in the computer systems of your business can give rise to the possibility of the obsolete technologies and control systems becoming vulnerable to it. The flow control equipment is the nervous system of an operation and can be affected in such situations and hence needs to be upgraded.

♦ Historic records help identify patterns in the maintenance of the equipment, recurring problems, frequency of services etc. This data can be used to accurately gauge the need for an upgrade.

♦ Real-time data is equally important and is utilised to keep a check on the accuracy levels of the flow control equipment and helps decide the correct time for an upgrade in this system.

♦ If the flow meter system requires expensive maintenance frequently or its parts are becoming increasingly costly or you need to shelve out a lot of money to hire a technical specialist, it’s time to upgrade the system.

♦ Partial upgrades are also cost-effective and easy to implement. A trained engineer should be hired to implement any type of partial or full upgrades in the flow control system to ensure that there are no glitches in the system. Similarly, for flow meter calibration, it’s advisable to hire calibration experts of an accredited calibration lab.

Selecting a New Flow Meter

In case there is a need for new equipment, keep in mind the following factors before buying a new flow meter:

  1. Model – There are various models of flow meter available today which fulfil different applications and purposes. A simple profiling of material which is to be measured can help you understand the material’s behaviour when flowing through a pipe. This can help you narrow down on the model of the flow meter. If you are unsure about how to follow this procedure, seek the services of a professional.
  2. Objective – The type of liquid or gas to be measured, the turndown ratio, required temperatures and whether it will be operated manually or automatically are some of the parameters which can help you zero down on the objective of buying the flow meter.
  3. Material Compatibility – It’s extremely important to take into account the materials which are to be measured with the help of the flow meter. The model you choose should be compatible with the materials it is supposed to measure. Check each material individually against a reputable chemical compatibility table. Also check your choice of the model with the manufacturer of the fluid to avoid any compatibility issues or problems.
  4. Cost – A cheaper device may be tempting, but it can cost you more in the long run than the price you pay while buying. First, consider the quality, durability and the performance of the device. If it meets your requirements perfectly, even a slightly expensive flow meter will prove to be cost-effective in the long term.
  5. Fitting – You also need to consider the fitting or the installation of the flow meter. Keep in mind the exact location of where it is to be installed as this parameter can highly affect the device’s efficiency and accuracy. Is it likely to be affected by any obstructions in the pipelines such as bends, valves or joints? These aspects can hinder the flow of the materials to be measured hence consider them before making the purchase.

Choose a flow meter which suits the needs of your business. Also, keep in mind that the flow meter should be upgraded and calibrated as required at the right time for optimal outcome. Such simple steps can help boost the efficiency of your operations.

Waste Water flow measurement in open ended pipes, now possible under all conditions

Accuron Cartridge-insert, open ended pipe flow meters
to fit nominal diameters 4″ – 24″ 

The successful measurement of low flows in partially full pipes and open channels has never been easily accomplished. Problems have ranged from questionable theory to real maintenance issues encompassing fouled sensors, sediment and plugging. The “point velocity” and “line velocity” theories that imply a velocity measured on the fluid surface or near the pipe wall can be substituted for the average velocity throughout the cross-section of the pipe have always been significantly challenged. In addition, flow sensors that sit in the invert of the pipe or hang from the top have made installation difficult, while providing a place for rags and other debris to accumulate. The accuracy of these single technology flow meters are only consistent within a specific or prescribed range of conditions. If conditions change, the stated accuracy ratings are no longer valid.

A new solution…. Accuron Hybrid Technology Cartridge Meters combine two distinct technologies in order to achieve maximum efficiency for monitoring of such flow under all conditions.

The Cartridge Meter is the first open channel flow meter to utilise hybrid technology. The new technology combines a stainless steel trapezoidal flume and Teflon level sensor combination for low flow applications with the highly accurate and non-fouling transit-time chordal velocity method for high flow applications. This new hybrid technology system allows for precise and highly accurate flow measurement during extremely low flows, high flows, flood events, reverse flows, stagnation and non-uniform hydraulic profiles.

High Performance under all conditions

During periods of minimal flow (Zero to 1/3 pipe diameter), The Accuron measures flow within its’ low operating range by utilizing the highly efficient combination of a trapezoidal flume and ultrasonic level sensor. Calibrated accuracy is ±3-5% of actual rate at a turndown: 60:1

During periods of maximum flow (1/3 to full pipe diameter). The Accuron measures flow within its high operating range by utilizing an extremely accurate area-velocity system that combines an ultrasonic level sensor with a pair of transit-time velocity sensors.

The Accuron Cartridge Meter comes with the assurance that each critical component will remain perfectly aligned during its installation plus operate free from the ongoing costs of repetitive maintenance. Transit-time chordal measurement is the most viable technique for predicting average velocity. It provides for detection of chordal velocity across the entire path of the fluid being measured.

OPERATING BENEFITS:

30 Minute
Installation Time

A stainless Cartridge, pre-sized for its specific application, arrives at the job site as a fully integrated unit. Every component is factory precision aligned, calibrated and programmed in strict accordance to customer supplied operating specifications.

Maintenance
Free Operation

By utilizing “above the flow” ultrasonic level sensors and non-fouling velocity sensors, the Cartridge Meter remains free from the ongoing problems of sediment build-up, fouled sensors and accumulated debris.

Data Logging
Software Package

Qtrend is an Excel Workbook Flow Data Graphing Package specifically designed to interface with every Cartridge Meter. It incorporates specific formulas capable of charting and displaying all of the data collected by the meter’s onboard logger.

Flow Lab Accuracy Traceability

Prior to field shipment, each Cartridge Meter is NIST traceable tested, calibrated and certified at Eastech’s Flow Metrology Laboratory under the identical size and flow conditions specified for its ultimate application.

Cost Benefits

Accuracy and cost efficiency is guaranteed by providing the end user with a pre-engineered field ready system designed for “out of the box” installation as opposed to the traditional solution. A single cartridge, pre-sized for its specific application, arrives at the job site as a fully integrated unit, requiring only 30 minutes for installation. Every component is factory precision aligned, calibrated and programmed in strict accordance to customer supplied operating specifications.

Engineering and plant personnel may now specify an extremely reliable and cost efficient system to monitor and measure flow in a single assembly. The Accuron Cartridge Meter shifts the responsibility of installed accuracy from the field to the factory. The added labour and expense of field programming, precise sensor alignment and costly flume installation is totally eliminated.

Guaranteed Accuracy

Prior to field shipment, each Accuron cartridge Meter is NIST traceable tested, calibrated and certified at the factory’s Flow Metrology Laboratory under the identical size and flow conditions specified for its ultimate application.

Maintenance Free

The risk and expense associated with repetitive confined space entry due to fouled submerged sensor problems is eliminated by utilizing an “above the flow stream” submersible Teflon level sensor. The trapezoidal flume’s flat straight through bottom permits the flume to pass debris quite readily and reduces the problem of sediment build-up up-stream of the flume and the cartridge’s transit time velocity sensors are designed to prevent the accumulation of rags, branches and similar debris from interfering with the performance of the transducers.

Oilfield Water Operations Optimized by Flow Meters :: A White Paper published by Badger Meter

BACKGROUND

The energy industry is under constant pressure in all production environments In the face of rising costs and increased operating demands, exploration & production (E&P) companies are looking to maximize production – while ensuring safe operations and avoiding environmental impact

During the exploration and drilling stages at oil and gas fields, accurate and dependable flow metering equipment is essential to ensure production is optimized Produced water applications, in particular, challenge oilfield operators The costs associated with these processes can adversely affect the economics of the producing wells, thereby discouraging further development and leaving substantial reserves unrecoverable (See Fig 1)

Figure 1: During the exploration and drilling stages at oil and gas fields, accurate and dependable flow metering equipment is essential to ensure production is optimised.

This whitepaper describes how instrumentation manufacturers have responded to the needs of the upstream sector by offering proven metering techniques to meet demanding flow measurement requirements

INTRODUCTION

In the oil and gas industry, recent technological developments are changing upstream production dramatically and opening up reserves to economically viable extraction Unequivocally, this new development will have repercussions for the environment and the development of renewable energy and a sustainable energy economy

There is an ongoing global shift to unconventional resources such as shale and oil sands Many of the extraction techniques associated with these newer plays – such as hydraulic fracturing – are very water-intensive (See Fig 2)

 

 

 

 

 

 

 

 

 

 

 

 

Figure 2: Many of the extraction techniques associated with shale oil and gas plays are very water intensive.

Producing petroleum products out of the ground generates large volumes of water with undesirable qualities Produced water contains soluble and insoluble organic compounds, dissolved solids, production chemicals (corrosion inhibitors, surfactants, etc ) and solid particles

For petroleum companies, salt water produced during production operations constitutes a critical waste stream affecting their bottom line The disposal cost, covering transportation, capital requirements and infrastructure maintenance, may be as much as $10 00 per barrel A typical production field can produce tens of thousands of barrels of salt water each day

GROWING ENVIRONMENTAL CONCERNS

With an increased focus on corporate responsibility and sustainability, the proper handling and disposal of waste streams is critical to all oil- and gas-related businesses  Operators must ensure regulatory compliance while protecting assets, personnel and the environment

Prior to environmental regulations in the 1970s, produced salt water was disposed of using the most economical method available – often times intentionally discharging the water on the ground These past practices and current accidental releases of produced water are national issues that concern managers of Native American, federal and state lands, as well as oil and gas producers, mineral rights and lease owners, state and federal regulators, and landowners

Tight gas, shale gas, oil shale, and liquids-rich, low-permeability plays are now frequently economically viable, and they are being produced in higher volumes than ever before Along with the higher volumes of oil and gas are increased amounts of produced salt water

CHALLENGES FOR WELL OPERATORS

The flow of liquids and gases must be measured during every phase of oil and gas exploration, production and transportation  This includes production well testing, enhanced oil recovery, fracking and separation to recover and prepare crude oil and produce water These applications demand the highest flow meter accuracy and reliability, as well as long-term stability and a low cost-of-ownership

Today, E&P companies have an urgent need to meet their water management challenges One of these challenges, in particular, is the fact that produced water streams must often be treated prior to disposal or reuse The

capital and operating costs associated with most treatment systems can be very high The need for economical management of produced water is critical

After the drilling & completion phases, the production phase utilizes three-phase separators to separate produced water from oil and gas Pump trucks visit well sites on a frequent basis to collect the water and haul it away to an offloading Salt Water Disposal (SWD) facility In certain areas, this is a very costly practice

The disposal of produced salt water, as well as other defined oil and gas wastes, is controlled by each state’s regulatory agency The most common disposal method is to inject the produced water and associated wastes into suitable, naturally occurring formations

Increasingly, oil and gas firms are seeking to minimize the need to inject produced water at disposal sites, reduce water trucking costs – and at the same time – increase production

PROVEN METERING TECHNIQUES FOR WATER BASED MEDIA

There is no question that flow measurement is a crucial aspect of numerous upstream operations – especially those around produced water With countless measuring instruments currently available, making an optimal meter choice can be a daunting task for operating companies Each type of flow meter used to measure oil & gas flow has its own advantages and disadvantages

Although electromagnetic flow meters have specific, limited uses in the oil and gas industry (since hydrocarbons are non-conductive), they are a reliable, cost-effective solution for chemicals, slurries and water/produced water, providing highly accurate volumetric flow measurements Magnetic meters are gaining usage in liquid separators, fracturing water, drilling mud and SWD applications

For example, produced water from well operation is highly conductive, and as such, an electromagnetic meter is one of the most popular approaches for measuring its flow Due to sediment and particulates in produced water,

a flow line may need to be pigged, making the electromagnetic meter an ideal choice Because these meters have no moving parts in the line, they can be pigged without shutting down the process to remove and reinstall the unit (See Fig 3)

 

 

 

 

 

 

 

 

 

Figure 3: Produced water from well operation is highly conductive, and an electromagnetic meter is one of the most popular approaches for measuring its flow.

The two main ultrasonic flow meter technologies are transit time and Doppler Transit-time flow meters are based on the time difference between upstream and downstream sound propagation intervals Doppler flow meters are based on the Doppler Effect The most commonly used ultrasonic device is the transit-time, single-path meter due to its proven accuracy, flexibility, and low cost

The demanding measurement requirements and challenging environmental areas found in the upstream sector can often lead to the selection of ultrasonic flow meters The fluid used in oil extraction and production is frequently pumped at high pressure and flow velocity, making the use on an invasive flow meter highly

challenging Many companies are also choosing ultrasonic meters because they can handle impurities in the flow better than most other designs (See Fig 4)

Figure 4: The demanding measurement requirements and challenging environmental areas found in the upstream sector can often lead to the selection of ultrasonic flow meters.

Wastewater Evaporators

Recent innovations in evaporation technology provide operating companies with an efficient, economical and environmentally responsible way to minimize wastewater transportation and disposal Key to this solution is accurate measurement of the evaporation process provided by electromagnetic flow meters

During the operation of a wastewater evaporator, the volume of high total dissolved solids (TDS) water entering the system is metered, followed by a measurement of the amount of salt crystals or concentrated water exiting the unit The delta of these two measurements is used to calculate the evaporation total, which is the basis for a per barrel service charge billed by the evaporator system provider to the oilfield operator

When used as part of an evaporation system, the electromagnetic flow measurement technique eliminates the need for moving parts, which can lead to performance and maintenance issues The meters measure virtually any conductive fluid or slurry, and are known for low pressure drop, high accuracy, extended turndown and excellent repeatability

Accurate flow data helps enable secure remote operation of an evaporator system – simplifying site personnel training and reducing overhead costs Additionally, improved reliability, increased robustness and reduced maintenance requirements can be achieved (See Fig 5)

Figure 5: Accurate flow data from electromagnetic flow meters can help enable secure remote operation of a produced water evaporator system.

In the future, cloud-based software solutions paired with wireless electromagnetic flow meters will enable unmanned monitoring of produced water consumption, storage and transportation at remote oilfield locations These systems will utilize endpoints to capture interval meter reading data through cellular or fixed network communication technologies They will employ data from the wireless mag meters to provide operators with readings of flow rates and hourly/daily/monthly totals, tank levels and other key parameters without visiting the well site Production decisions can then be made at a central operations centre to help optimize large producing fields

Hydraulic Fracturing

Hydraulic fracturing is the use of fluid and material to create or restore small fractures in a formation in order to stimulate production from new and existing oil and gas wells Fracturing creates paths that increase the rate at which fluids can be produced from the reservoir formations, in some cases by many hundreds of percent

Hydraulic fracturing is another common oilfield application for electromagnetic flow meter technology During this process, a mixture of abrasive sand, gel and water is pumped at high pressure into underground rock layers

where oil or gas is trapped Gelling agents are used for lubrication to increase fluid viscosity and make it better able to carry sand This is a key step in holding fractures open Additional chemical injection is used to reduce friction, attack microbes and minimize equipment corrosion

Electromagnetic flow meters are the perfect fit for skid installation, require upstream/downstream straight pipe runs, and provide high measurement accuracy Compared with traditional mechanical meters, electromagnetic meters reduce or even eliminate expensive service, replacement part costs, and downtime

By employing electromagnetic flow meters, operating companies can maintain precise control of the fracturing fluid and the blending of additives This application wears out many other flow meter technologies and can result in an unstable flow signal, making the measurement unusable Once the fracturing process is complete, production can begin

Drilling Mud

During drilling and wellhead installation, precise control of the flow rate of drilling mud going down the borehole to cool the drill bit is a critical step in preparing the well The drilling mud is typically a mixture of water, sand and

a range of chemicals The flow meter used in this application must be able to withstand abrasive materials as well as harsh environmental conditions such as moisture, varying ambient temperature ranges, and vibration in the drilling rig (See Fig 6)

 

 

 

 

 

 

 

 

Figure 6: Flow meters used in drilling mud applications must be able to withstand abrasive materials as well as harsh environmental conditions.

The use of electromagnetic flow meters to measure drilling mud can enable oilfield operators meet rigorous production requirements, reduce risk and avoid unnecessary downtime The meters utilize long-lasting sensor lining materials to ensure resistance to chemical corrosion and abrasion, resulting in extended service life

Unlike many other flow instruments, they have no rotating parts inserted in the pipe This can help do away with premature wear, frequent maintenance and associated service costs

At the same time, non-intrusive ultrasonic flow meters perform efficient measurement of mud flow system return lines when the drilling mud contains beads, which are good reflectors for Doppler ultrasound metering technology

Phase Separators

Phase separators reside on onshore well pads and offshore platforms and can be horizontal or vertical They’re used in upstream oil and gas applications for periodic well testing (as a test separator) or continuous production measurement (as a production separator), and can function in either two-phase or three-phase depending on operator strategy (See Fig 7)

 

 

 

 

 

 

 

 

 

 

 

Figure 7: Oil three phase separators are used to separate the oil from the gas and water.

The separator is primarily intended to separate the oil from the gas and water On a three-phase separator, all the phases have to be accurately measured and monitored Electromagnetic flow meters are a common choice for water measurement process due to their straightforward design with no moving parts and no path obstructions The meters provide accurate flow readings, which tell operators how their wells are performing and how much oil, water, and gas they’re producing These measurements also assist with fine-tuning recovery operations to maximize retrieval of hydrocarbons

Salt Water Disposal

The process of oil and gas production creates “salt water,” which is considered a hazardous waste because of its high salt content, hydrocarbons, and industrial compounds Companies can recycle the water, injecting it back into working reservoirs for reuse in gathering any remaining oil or gas, or they can discard it at a salt water well disposal site

Ultrasonic flow metering has gained popularity for salt water disposal applications Installation of the meters takes place without interrupting the production and without cutting into the pipe The transducers are simply clamped onto the pipe and do not cause any pressure loss Since they do not come in contact with the medium, they are not subject to wear And, with its sophisticated ultrasonic transducers and superior signal processing capabilities, the measurement system is highly accurate and reliable

Electromagnetic flow meters also play a role in salt water disposal They can be used to reliably measure abrasive discharge fluid pumped to and from wells, and are robust enough to withstand operational vibration on truck- mounted, process water blending units

BENEFITS TO E&P COMPANIES

Whether it’s improving accuracy, decreasing system maintenance or meeting the demands of challenging liquid and gas conditions, modern flow meter technology delivers the performance critical oil and gas applications require

There are numerous benefits to using electromagnetic flow meters to perform fluid flow measurements in E&P operations They are generally non-invasive and have no moving parts, reducing the risk of breakdowns and the frequency of repairs Increased activity in oil and gas production and exploration will continue to put ultrasonic flow meters in the measurement spotlight These meters are simple and inexpensive to install

CONCLUSION

The oil and gas industry deals with a host of troublesome applications, including produced water evaporation, hydraulic fracturing fluids, drilling mud, three-phase separators and salt water disposal Such applications can be difficult for many flow measurement instruments to handle

Sticking to the old adage of “if it’s not broke don’t fix it” – and not utilizing the best available technologies – could cost petroleum producers and other support companies millions of dollars For many oilfield operators, advanced electromagnetic and ultrasonic flow meters are the instruments of choice when considering cost, accuracy and the service life of installed equipment

Non-Invasive Heat Meters plus remote data collection and viewing in major London train station

Bell Flow Systems help to monitor heat energy usage at a major London train station

Bell Flow Systems were recently approached by a contractor to provide a heat flow measurement system which would provide short term monitoring at a number of locations around a major London train station for a period up to 6 months. As the project was short term the flow meters had to utilise a non-invasive technology, which would not interrupt the flow of water or require modifications to the existing pipework. The client also required the information from the heat flow meters to be recorded on a regular basis so the information could be analysed and assessed remotely. It was specified that the units should be simple to configure and connect to and also to ensure that the systems were flexible so that they could be utilised in other areas of the station for recording information in future applications.

Ultrasonic flow meter fitted to pipe

For the project our low cost BFU-100-RF clamp-on ultrasonic heat flow meter was chosen, along with our Point Green telemetry system. The BFU-100-RF models provide non-invasive measurement from the outside of the pipes using transit time ultrasonic technology. This combined with a pair of clamp-on temperature sensors at each location on the supply and return pipes, meant real-time and accumulated energy readings could be produced. This information was then collected via the Modbus output from the meter and stored for local collection by PC, when the client was able to collect and record the readings to CSV format.

Remote data access via GSM / GPRS

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The client also required the use of the Point Green’s GSM / GPRS functionality to recording readings remotely, for access off-site via our secure data portal, where information can be accessed simply using in an internet browser from anywhere in the world.
