ATEX Approval for TFX-5000 ultrasonic clamp-on Flow meter

Feb 7, 2020

Dynasonics^® TFX-5000 ultrasonic clamp-on flow meters for liquid flow measurement and Heat metering (Heating & Cooling flows) include data logging and alarm history with a time and date stamp and are ideally suited for HVAC, water and wastewater, oil and gas and industrial flow and energy measurement applications.

Badger Meter is happy to announce new hazardous area certification to ATEX/IECEx Zone 2 for the Dynasonics® TFX-5000 transit time ultrasonic flow meter. The certification covers models measuring DN65 and larger, making the solution ideal for flow measurement in automotive, waste water, oil and gas and other general industrial applications requiring hazardous zone approvals.

Whilst this model can be specified for pipe diameters DN12 to DN1200, the approval covers models from DN65 and above and classification is:

• II 3 G Ex ec nC ic IIC T4 Gc

• II 3 D Ex tc IIIC T100 °C Dc

The TFX-5000 meter uses transit time measurement to determine the flow rate and total volume. When ordered as an energy meter option with the supplied pair of PT1000 RTDs, the TFX-5000 energy meter can calculate heat transfer rate and energy usage. As the TFX-5000 meters' clamp on flow sensors clamp on to the outside of the pipe, there is no requirement to tap or cut into the pipe, providing considerable benefits in terms of the reduction in total installation cost while eliminating the potential for contamination and meter fouling.

The TFX-5000 non-intrusive flow meter replaces the Dynasonics^® TFX Ultra - ultrasonic clamp-on meter and is suited to the same applications and more whilst it also includes the following improvements:

• Data logging and real-time clock
• Addition of the adjustable small pipe transducer, only one sensor for small pipes!
• Large display with keypad and improved diagnostic messages
• Improved pipe clamp RTDs for energy metering
• AquaCUE^® Flow Measurement Manager/BEACON^® Advanced Metering Analytics with remote connectivity
• Security passcode protection
• English, French, German, Italian and Spanish configuration menus
• SoloCUE^® Flow Device Manager configuration software (included free with each model purchased)
• The TFX-5000 meter is CE certified. (ATEX approval is on-going and expected for early 2020.)
