I. Working Principle of Orifice Plate Flow Meters

An orifice plate flow meter is a differential pressure flow meter that operates based on Bernoulli's theorem and the continuity equation. When fluid flows through the orifice plate, due to the sudden reduction in the flow cross-section, the fluid velocity increases, and the pressure decreases, resulting in a pressure difference across the orifice plate. By measuring this pressure difference and combining it with known fluid parameters and the geometric dimensions of the orifice plate, the fluid flow rate can be calculated.

II. Applications of Orifice Plate Flow Meters in Energy Measurement
