Ultrasonic Flowmeters - Transit Time

An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow.(1.)

The three types of Ultrasonic flow meters are:

  1. Transit-time (Transmission) - In-line (intrusive or wetted) and Clamp-on (non-intrusive)
  2. Doppler shift
  3. Open-channel 

An ultrasonic flow meter will measure the difference of the transit-time of the ultrasonic pulses that are generated with and against the flow direction. This time difference is a measurement for the average momentum of the fluid along the path of the ultrasonic beam. The average fluid velocity and speed of sound can be calculated by using the absolute transit times.

The ultrasonic industrial transit time flow meter will deliver high accuracy flow measurement for a wide array of liquids and pipe sizes.
