KPL orifice plate assemblies are commonly used to provide a reliable and often cost-effective differential pressure reference to allow for flow rate measurement in medium to large diameter industrial piping. If a pipeline (through which a media flows) is reduced at a particular point by a cross-sectional constriction, the flow speed of the measured media is increased at that point.

According to Bernoulli’s energy equation and the law of continuity, the total flow head (dynamic velocity head and static pressure head) is constant. The increase in speed at the constriction causes a reduction in the static head. The resulting pressure drop is called the differential pressure head and may then be used to measure the flow rate (volume per unit of time or mass per unit of time). The flow rate is a function of the square root of the differential pressure across the orifice plate. This rate can then be determined by use of an appropriately scaled differential pressure transducer or gauge.
