Flowmeters : Differential Pressure Venturi Flowmeter
A flowmeter is an instrumentation device used to measure and record the flow rate of a gas or fluid. A venturi flowmeter makes use of the Venturi effect to calculate the flow rate. The flow is constricted through a section of the meter and the pressure is measured both upstream and downstream of the constriction. The change is flow area and the differential pressure are then used to calculate the flow rate.
