Orifice Plate Flow Meter

An orifice plate flow meter measures fluid (liquid, gas, steam) flow rate by installing a thin plate with a precise hole (the orifice) in a pipe, creating a constriction that increases fluid velocity and causes a measurable pressure drop (differential pressure) between the upstream and downstream sides, allowing calculation of flow based on Bernoulli's principle. It's a simple, cost-effective differential pressure meter used across many industries for its reliability and ease of maintenance.
