Explanation:

  • Venturimeter is a device that measures the flow rate of fluid through the pipe. It can be used in any position.
  • When a venturimeter is placed in a pipe carrying the fluid whose flow rate is to be measured, a pressure drop occurs between the entrance and throat of the venturimeter.
  • This pressure drop is measured using a differential pressure sensor and when calibrated this pressure drop becomes a measure of flow rate.
