What is Orifice Plate Flow Meter?

An orifice plate flow meter is a device with a hole in it, the function of which is for measuring volume flow rate, restricting flow, or reducing pressure. The device is applicable for common measurements in clean liquid, gas, and stream flow. It’s compatible with any pipe diameter and is known as an economical flow measurement solution on bigger line sizes.

Orifice Plate Flow Meter Working Principle

An orifice meter determines a gas or liquid flow-rate by using the Bernoulli's principle, which acknowledges the relationship between the pressure and the velocity of the fluid. The device is installed in the flow pathway, allowing the fluid to pass through it. As a pressure drop occurs between the inlet and outlet section of the device, the magnitude of the drop will be used as a basis for calculating the flow rate. This working principle is identical to that of venturi meter.
