Model TFX Ultra® is available in two versions: As stand-alone ultrasonic flow meter, and as energy flow meter used in conjunction with dual clamp-on RTDs. The energy flow meter measures energy usage in BTU, MBTU, MMBTU, Tons, kJ, kW, MW and is ideal for retrofit, chilled water and other HVAC applications.
As stand-alone flow meter, type TFX Ultra® can used for flow measurement of clean liquids but also liquids with small amounts of suspended solids and gaseous liquids.
Type TFX Ultra® offers bidirectional flow measurement within a velocity range of 0,03 to 12 m/s in pipes sizes of DN50 to DN3000 with an accuracy of +/-1% of reading or +/-0,003 m/s and within a temperature range of -40°C to +85°C. Totalisator options deliver quantity measured in flow or reverse flow direction as well as total flow rate. USB 2.0, ModBus® RTU and BACnet® MSTP via RS485, Ethernet connection with BACnet®/IP, EtherNet/IP and ModBus® TCP/IP protocoles are available as output.
Type TFX Ultra® clamp onto the outside of pipes and do not contact the internal liquid. Clamp-on sensors eliminate the need for in-line flanges, pipe fittings, strainers and filters. With no moving parts, there is nothing on the TFX Ultra® to wear down - no repair kits or replacement parts are needed. The TFX Ultra® may be installed and fully operational within a few minutes. No need to shut down the process for installation or maintenance due to the clamp-on-sensor design. The meter has a large, easy-to-read two-line digital display with backlight and the rugged, aluminium enclosure ensures a long service life in harsh environments.
TFX Ultra® is certified for hazardous area installation in Europe.
