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

• May be used 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/IPTM 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.
• Reduced material costs: clamp-on sensor eliminates the need for in-line flanges, pipe fittings, strainers, and filters.
• Reduced installation time: the TFX Ultra may be installed and fully operational within minutes.
• Reduced maintenance costs: with no moving parts, there is nothing on the TFX Ultra to wear down – no repair kits or replacement parts are needed.
• No need to shut down the process for installation or maintenance due to clamp-on sensor design.
