Balanced orifice plate

Optimized & Industry-ready Solutions

For All Your Complicated Needs

Balanced orifice plate, or multi-hole orifice plate, is an advanced differential pressure flow element. Its symmetrically arranged multiple bores condition the flow profile, mitigating turbulence and swirl. This design significantly reduces required upstream straight pipe length, minimizes permanent pressure loss, and enables a wider turndown ratio compared to a standard single-hole orifice. It is ideal for constrained installations and measuring challenging fluids.
