Orifice Plate

An orifice plate is a device used to measure the rate of fluid flow. It uses the same principle as a Venturi nozzle, namely Bernoulli's principle which says that there is a relationship between the pressure of the fluid and the velocity of the fluid. When the velocity increases, the pressure decreases and vice versa.


Orifice plates are most commonly used for continuous measurement of fluid in pipes.

They are also used in some small river systems to measure flow at locations where the river passes through a culvert or drain.

Orifice plates are used to control onward flow in flood relief dams.

Function:

Accurate workmanship and high quality of finish distinguishes “NISAN” orifice plates. NISAN orifice plate is basically a thin plate with a hole in the middle. It is usually placed in a pipe in which fluid flows.

USES:

Orifice plates are most commonly used for continuous measurement of fluid in pipes.

They are also used in some small river systems to measure flow at locations where the river passes through a culvert or drain.

Orifice plates are used to control onward flow in flood relief dams.
