TFX Ultra Transit Time Flow Meter

TFX Ultra® transit time ultrasonic meters measure volumetric and energy flow of clean liquids, as well as those with small amounts of suspended solids or aeration, such as surface water or sewage. 

Ultrasonic waves are transmitted from outside the pipe into the liquid and propagate upstream and downstream. The flow velocity is determined by the difference in the time of flight and is used to calculate the volumetric flow.

For energy metering, the temperature difference across heating and cooling equipment or zones is measured by dual RTD’s and is used with the volumetric flow to calculate the energy transfer.
