Ultrasonic Inline or Portable Clamp on Flowmeters

The operation of Ultrasonic transit time flowmeters can be compared to someone walking in a river between two points. Walking downstream with the current will take less time to cover the distance than walking upstream against the current; from the difference in time we can derive the velocity the river is flowing at. In flowmeters an ultrasonic beam is directed between two points, first one way then the reverse. The difference in time taken or transit time, allows us to derive the velocity of the fluid flow. Once the key variables are allowed for, accurate and reliable flow measurement is possible.

We offer solutions using this principle in two ways:-

  • FL50 series in-line body with fixed sensors to give a robust, reliable water meter
  • SL1168P non invasive sensors & hand held instrument which clamp on to the outside of a pipe for portable flow & volume measurement.
