Why are our orifice plates the practical choice for system control points? Our measurement tolerances are highly controlled and within their accuracy coefficient range. In fact, their accuracy is within ±1% over beta ratios from 0.2 to 0.7.

Featuring a versatile design, our flow rate measurement devices can be used to measure liquids, gas, or steam in nearly all closed-pressure piping systems. In addition, they’ve been used successfully in both fossil-fueled and nuclear-powered steam/electric-generating plants. Our orifice plates are also applicable for a wide range of boiler applications, including low pressure and supercritical.
