Flow Measurements

About Flow Measurements

Flow measurement is extremely important in all the process industries. The manner in which the flow rate is quantified depends on whether the quantity flowing is a solid, liquid or gas. In the case of solids, it is appropriate to measure the rate of mass flow, whereas in the case of liquids and gases, flow is usually measured in terms of the volume flow rate. In a few cases, such as measuring the rate of usage of liquid fuel in a rocket, it is necessary to measure the mass flow rate of a liquid, and special techniques are available for this.
