Measurement of Flow Rate

The simplest method of measuring flow rate is with a measuring container and a stop watch. However, turbine meters are recommended for continuous measurements. The speed indicated provides information about the value of the flow rate. Speed and flow rate behave proportionally.

Another alternative is to use an orifice. The fall in pressure recorded at the orifice is an indication of the flow rate (pressure drop and flow rate behave proportionally), measurement by orifice is scarcely influenced by the viscosity of the hydraulic fluid.
