What Is an Orifice Plate?

The orifice plate is installed in a closed pipe, and a detection element that measures the flow of liquid, gas and steam according to the principle of a throttling device. The standard orifice plate is a thin metal plate with a circular opening. The wall of the orifice is at right angles to the front face of the orifice plate. The axis of the orifice plate is concentric with the axis of the pipe during installation.

Orifice plate

Orifice plates are installed in closed pipes.

Orifice plates have international standards (ISO 5167). Measure the pressure difference between the two ends of the orifice plate.

Using imported single crystal silicon intelligent differential pressure sensor

High precision and perfect self-diagnostic function

The range of the intelligent orifice plate flowmeter can be adjusted by self programming.

Can display cumulative flow rate, instantaneous flow rate, pressure and temperature at the same time.

In addition to online and dynamic full compensation, it also has self-diagnosis and self-setting range.
