• Meets or Exceeds AGA, ISA, ANSI, ASME & API StandardsProduct Description
USA Industries' Universal Orifice Plates, also commonly called differential pressure orifice plates, are designed to be used with all standard orifice fitting assemblies or ring type joint plate holders. Standard industry sizing also allows our plates to be used with any of the dual- or single-chambered orifice fittings on the market. They are the most commonly used method of differential pressure flow measurement due to their simplicity, predictable and reliable performance, ease of installation, and tolerance to extreme atmospheric and process conditions.
Our orifice plates conform to the most stringent manufacturing processes to achieve optimum accuracy standards in the industry. Our engineering staff can run your orifice bore calculations quickly and accurately.
Orifice plates are stocked in 304 & 316 stainless steel and available in any material requested, such as monel, hastelloy, copper, nickel, and more. USA Industries' can also coat your orifice plates with any coating you require.
Seal rings snap in after the orifice plate is installed into carrier. This creates a seal on the upstream side of the orifice plate and on the upstream side of the fitting seat.
Seal Rings for Series 500 orifice plates are sold separately.
