Venturimeter Apparatus

The Venturi meter is a device used to measure the flow rate. As shown, it consists of a tapering contraction section, along which the fluid accelerates towards a short cylindrical throat, followed by a section which diverges back to its original diameter.

As velocity increases from the inlet section to the throat, there is a fall in pressure, the magnitude of which depends on the rate of flow. The flow rate may therefore be inferred from the difference in pressure, as measured by pizometers placed upstream and at the throat.
