Description Orifice plate is very practical and relatively low-cost measuring device for flow rate measurement with good accuracy. By placing orifice plate in the pipe, sudden pressure drop is created. Degree of created pressure drop is directly proportional to the stream velocity and consequently, to the flow rate. That behavior and strong interaction between stream velocity and pressure drop due to local restrictions is used for flow rate measurement by orifice plate. This calculator can be used for calculating of actual flow rate through orifice plate flow meter, for measured pressure drop and can also be used for orifice plate sizing.
One type is the restriction orifice plate, which in construction and calculation follows. For this type of restriction orifice plates the flow quantity through the orifice.

It has been shown by Cunningham that a standard plate constructed according to ISO 5. Ward- Smith has shown theoretically that critical velocity can be obtained, when the discharge coefficient C is approaching 1. The discharge coefficient is 0.
