Orifice plate is used for flow rate measuring in pipe systems. With orifice plate, pressure drop is created. Based on the magnitude of pressure drop, flow rate can be calculated. This instrument is very practical for large tube diameters and for dirty fluid when turbines are not applicable.

Orifice Plate - An orifice plate helps measures flow through the differences in pressure from the upstream side to the downstream side of a partially obstructed pipe. The plate offers a precisely measured obstruction that narrows the pipe and forces the flowing substance to constrict.

To calculate the flowrate of a fluid passing through an orifice plate, enter the parameters below. (The default calculation involves air passing through a medium-sized orifice in a 4" pipe, with answers rounded to 3 significant figures.)

Small diameter (bore) orifice plate flow meter software for liquids ... Orifice flow meters are used to determine a liquid or gas flow rate by measuring the differential pressure (P1 - P2) across the orifice plate. The two standard pressure tapping arrangements for small bore orifices are shown in the drawings;

The orifice plate is commonly used in clean liquid, gas, and steam service. It is available for all pipe sizes, and if the pressure drop it requires is free, it is very cost-effective for measuring flows in larger pipes (over 6" diameter).
