Product Details

Due to the advantages of simple structure, easy processing, low manufacturing cost and convenient installation, the restriction orifice plate can be used instead of regulating valve to limit the flow or reduce the pressure, which will greatly reduce the investment and operation and maintenance costs.

The restriction orifice plate can be used as a flow measuring element to measure the flow and as a throttling element to limit the flow and reduce pressure

When there is a certain pressure difference before and after the orifice plate, the fluid flows through the orifice plate. For a certain aperture, the flow through the orifice plate increases with the increase of the pressure difference.

However, when the pressure difference exceeds a certain value (called critical pressure difference), the flow velocity through the hole shrinkage of the orifice plate reaches the speed of sound. At this time, no matter how the pressure difference increases, as long as the pressure on the upstream of the orifice plate remains constant, the flow rate through the orifice plate will remain at a certain value and will not increase.

According to the number of orifice plate can be divided into single stage and multi - stage.


●Restriction orifice plate flow meter has simple structure, firm, stable and reliable performance, long service life and low price.

●Executive standard:ASME ISO-5167

●The fluid to be measured must be full of piping and throttling and continuous flow through the pipe

●It can be used without real flow calibration.
