TFX Ultra™ Fixed Clamp-on Ultrasonic Flow & Heat Meter

TFX Ultra™ Fixed Clamp-on Ultrasonic Flow & Heat Meter

TFX Ultra™ – Clamp-on Ultrasonic Flow & Heat Meter :: DN12 to DN3800

The TFX Ultra is available in two versions: a stand-alone flow meter, and a Heat Meter or Thermal energy flow meter used in conjunction with dual clamp-on RTDs. The Heat flow meter measures energy usage in kW, MW, BTU, Tons etc, and is ideal for retrofit, chilled water and other HVAC applications.



TFX Ultra ultrasonic flow and energy meters clamp onto the outside of pipes and do not contact the internal liquid. The technology has inherent advantages over alternate devices including: low-cost installation, no pressure head loss, no moving parts to maintain or replace, no fluid compatibility issue, and a large, bi-directional measuring range that ensures reliable readings even at very low and high flow rates. TFX Ultra is available in a variety of configurations that permit the user to select a meter with features suitable to meet particular application requirements.

Features of the TFX Ultra include:

  • Ability to measure liquids with small amounts of suspended solids or aeration (e.g., surface water, sewage).
  • Bi-directional flow measurement system. Totalizer options include forward, reverse and net total.
  • Modbus RTU over RS485 communications; Ethernet connection includes BACnet/IP®, EtherNet/IP™ and Modbus TCP/IP protocols.
  • Compact enclosure uses large, easy-to-read digital display.
  • Rugged, aluminum enclosure ensures a long service life in harsh environments.
  • ATEX Certifield for hazardous areas
