What does an orifice in a pipe do — and why is it so widely used in engineering?

An orifice is a small opening, usually in a thin plate, placed inside a pipe. As fluid passes through this restricted opening, it accelerates, causing a drop in pressure. This pressure difference is key: it allows engineers to accurately measure the flow rate of liquids or gases using basic principles of fluid dynamics.

But measurement isn't the only benefit.

Orifices also help control flow by limiting how much fluid can pass through a system — without any moving parts. They are simple, cost-effective, and reliable. In many systems, they also help reduce pressure, regulate speed, or generate turbulence to improve mixing or downstream efficiency.

💡 Whether in industrial processes, HVAC systems, or lab setups, an orifice is a compact tool with powerful applications.
