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.
