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. Further Alarms and important warnings are shown on-line or send via SMS and e-mail. Further information here>>>

A lightweight and compact water level meter- little dipper2

little dipper2

Ground water wells and bore holes are often located in secluded areas or are not easily accessible by vehicle.  You may have to travel to such a remote location on foot when roads are not available or passable due to natural events, such as flooding or snowfall.

In these cases, the size and weight of the equipment you need to transport can add significant cost and inconvenience to a project.  To alleviate some of these issues, Heron Instruments offers the little dipper2, available from Bell Flow Systems in the UK.

The little dipper2 in static mode is used for measuring the depth of water. The little dipper2 in drawDown mode may be used for measuring falling water levels during purging, well development and for low flow sampling; helping to protect your pumps from damage caused by dry running.

The dimensions of this water level meter are 19.5 cm x 18.7 cm x 30.5 cm, making it small enough to transport in a backpack.  With the reel assembly weighting only 1.36 kg the total weight is determined by the tape selected.  It is available in 15m, 22m and 30m tape lengths while still maintaining its compact size. The little dipper2 offers most of the features of the full size dipper-T2:

  • – A polyethylene jacketed high tensile steel tape
  • – A full pressure rated 5/8” probe
  • – Choice of metric or engineering scale tape markings

Batch Control for Formic Acid

A client was looking for a solution to measure a process involving a solution of water and formic acid, and approached us at Bell Flow to assist. The customer required a solution for dispensing specific amounts of formic acid solution for use in their drain cleaning products. After a meeting with the client, we discussed their current process and their desired changes. The most appropriate solution was to install a complete system of batch control for formic acid.

Formic Acid Challenges

Formic acid is a chemically aggressive substance. Considering the nature of the substance, we had to check the compatibility of construction materials, and also any seals. The most suitable material for the task was 316 stainless steel. 316 Stainless steel has excellent chemical compatibility, corrosion resistance, but is particularly effective in protecting against corrosion in acidic environments. Ultimately, Bell Flow quoted three products to fit the brief accordingly – a Blancett B1100 turbine and solenoid valve, both in stainless steel. And finally, a Fluidwell F130 batch controller, with mechanical relay output to complete the set up.

Bacth control for formic acid

This allows the customer to enter the volume required into the batch controller. The flow is subsequently measured accurately by the flow meter. Pulses are then sent to the batch controller, which in turn closes the valve at a set value. Allowing for controlled, precision batch measurements. This system ensures accurate batch control for formic acid. Ultimately producing an end product of consistent quality specifications.

Is the UK facing a water shortage? It’s time to save water

Wasting water and how to save water has been a hot topic in the UK media lately. Despite the recent storms and torrential rains causing flooding across the UK, the country is under threat of future droughts by 2050 if we don’t change how we use our water. The Environment Agency has published warnings that we could be left facing water shortages across the UK – with the South East being particularly at risk.


Sprinklers - no good when trying to save water!

Climate change, population growth but also wastage are the main areas of concern. Leaking pipes waste 3 billion litres of water every day.
Plus, each person using on average 140 litres of water a day.

We are subsequently wasting a very significant percentage of our naturally sourced water on a daily basis. The knock on effect of this on the Eco-system and security of our future water supplies is of huge concern. The Environment Agency is increasing pressure on the water companies, industrial customers and the general public to focus on how they can save water.

Why should I save water?

There are many reasons you should be looking for ways to reduce your water usage.

  • – Water restrictions, hosepipe bans and water rationing will become a real possibility if we don’t change how we use water.
  • – Reducing pressure on the water infrastructure and the environment.
  • – Energy used to heat water contributes towards our carbon footprint and subsequently climate change.
  • – It can save your household money! Save water, save money.

“We need to change our attitudes to water use. It is the most fundamental thing needed to ensure a healthy environment, but we are taking too much of it and have to work together to manage this precious resource.”
said Emma Howard Boyd, the Environment Agency chair woman.

So, how can I save water? Here’s some quick tips…

We can reduce our water consumption at home with a few small changes to how we use it.

  • – Turn off the tap whilst brushing your teeth. Take showers instead of baths.
  • – Use your washing machine and dishwasher for full loads whenever possible – and make use of ‘Eco’ settings and features on certain models.
  • – Reuse dishwater or bathwater to water the garden.
  • – Consider purchasing a water butt for storing rainwater to water your plants.
  • – Check your toilet and taps are not leaking (how?)
  • – Ask your water company about water saving products. Many supply their customers with these products free of charge.
  • – Assess your water usage with the use of an accurate and easy to read water meter.

Flow meters, or water meters are an extremely useful tool to help you save water. When you know what your consumption is, you can create targets to lower your use. Water meters can be installed in to existing systems to measure all, or part of the building’s water use. You can use an easy to install water meter on your external supply to measure how much water you use outside, or how much is being used in the bathroom. We have a range of WRAS approved water meters suitable for domestic and business use. Water meters are also a useful tool to monitor and identify any unusual spikes in normal water use, which could indicate a leak!
