The TFX Ultra transit time ultrasonic meters from Dynasonics / Badger Meter 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. It works by transmitting ultrasonic waves 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.
