This ultrasonic flow sensor is used as the core element of ultrasonic flow meters. Ultrasonic flow measurement uses the transit time principle, whereby opposite sending and receiving ultrasonic flow sensors are used to transmit signals through the flow. The signal travels faster when moving with the flow stream rather than against the flow stream.
 
  The difference between the two transit times is used to calculate the flow rate. 
  Good performance.
