An orifice plate is a device used for measuring flow rate, reducing pressure or restricting flow (in the latter two cases it is often called a restriction plate).

The orifice, nozzle and venturi flow rate meters makes the use of the Bernoulli Equation to calculate fluid flow rate using pressure difference through obstructions in the flow.

An orifice plate is a thin, flat piece of metal with a precisely machined hole in the middle. This hole, or orifice, is designed to create a pressure drop in the flow of a fluid, which can then be measured to …

Measure, throttle, and regulate the flow of liquids and gases in your line by adding an orifice plate to these unions. Also known as flow restrictors and precision orifice valves, these orifices are used to …

Dec 7, 2025 · The orifice plate is a deceptively simple yet powerful tool in the field of flow measurement. For students and engineers working with pipelines, steam, water, gas, or process fluids, …

What is Flow Through an Orifice? Definition: This calculator determines the volumetric flow rate of a fluid through an orifice based on the pressure difference and fluid properties.

Jun 11, 2025 · Learn the fundamentals of orifice flow in fluid mechanics, including its applications, types, and calculations.

An orifice flowmeter operates based on the principle of flow restriction. When a fluid flows through a pipeline containing an orifice plate, the flow is constricted, causing a pressure drop across the plate.

What is an Orifice Plate Flow Meter? The orifice plate flow meter is a type of differential pressure flow meter that is commonly used in clean liquid, gas, and stream mass flow measurement.

Dec 5, 2024 · Flow orifices are simple, cost-effective, and robust solutions for accurate flow measurement in industrial systems. Their versatility and durability make them a preferred choice for …
