This article will delve into the differences and advantages of orifice plate flow meters compared to other flow meters, taking you to appreciate the unique charm of this measurement technology.

I. Working Principle of Orifice Plate Flow Meter

An orifice plate flow meter is a differential pressure flow meter, mainly composed of three parts: an orifice plate, a differential pressure transmitter, and a flow integrator. When fluid flows through the orifice plate, due to the sudden reduction in the flow area, the fluid velocity increases and the static pressure decreases, resulting in a pressure difference before and after the orifice plate. By measuring this pressure difference and according to Bernoulli's equation and the continuity equation, the flow rate of the fluid can be calculated.
