Dynasonics® TFX Ultra
Clamp-on ultrasonic flow and energy meters for liquids
- Reduced material cost: 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

General information
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, MBTU, MMBTU, Tons, kJ, kW, MW and is ideal for retrofit, chilled water and other HVAC applications.
