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

Posted: Friday 21st February 2020

Badger has announced 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.

The approval classification is:

• II 3 G Ex ec nC ic IIC T4 Gc

• II 3 D Ex tc IIIC T100 °C Dc

TFX-5000 ultrasonic clamp-on flow and energy meters are a versatile solution for measuring volumetric flow and heating/cooling rates in clean liquids as well as those with small amounts of suspended solids or aeration, such as surface water or raw sewage. Typical applications include water mains, reclaimed water, lift stations and booster pump stations in water and wastewater or the energy transfer of chilled water (cooling) and glycol/hot water (heating) in HVAC systems as well as produced water in oil and gas applications.

As the newest generation of clamp-on ultrasonic flow and energy meters, the TFX-5000 meter is intended for users seeking an accurate, reliable and affordable transit time metering device, The TXF-5000 is available in a variety of configurations and can be selected with features suitable to meet particular application requirements.

By clamping onto the outside of pipes, ultrasonic devices like the TFX-5000 meter do not contact the internal liquid and have inherent advantages, such as reduced installation time and cost, no limits on pressure or fluid compatibility. The meter is available in two versions:

· A flow meter for water delivery, raw sewage, cooling water, sea water, deionized water, water-glycol mixtures, alcohols, chemicals and many acidic or caustic fluids

· A heating/cooling energy flow meter used in conjunction with dual clamp-on Resistance Temperature Detectors (RTDs) for temperature measurement in hydronic processes and HVAC systems

The TFX-5000 meter is specifically developed for fluid flow metering and heating/cooling energy measurement and can be employed for a host of data logging tasks. Users can select up to eight parameters to log, including flow rate and total, signal strength, and alarms with a time/date stamp to an 8 GB microSD™ (Secure Digital) card. It also features helpful diagnostics that take the guesswork out of isolating process or application problems. Users are alerted to out-of-specification flow conditions and can access a history with the most recent alarm, error and event codes.

In addition, the meter can be integrated into remote telemetry packages for cloud based viewing, monitoring and download.

The TFX-5000 meter features a large, easy-to-read graphical display and provides Modbus RTU, Modbus TCP/IP, BACnet MS/TP, and BACnet/IP connectivity. Configuration and troubleshooting are through an optional keypad or via a Universal Serial Bus (USB) cable using the included SoloCUE® Flow Device Manager software. The meter utilizes a four-level passcode security system for applications requiring unit lockdown. Installation is simplified with new Dynasonics Easy Rail Transducers, which provide a better acoustic interface and lessen the need to re-apply acoustic couplant due to installation errors.
