Orifice Integral Assembly

Integral Orifice Assembly Features

• Designed for direct mounting on Differential Pressure Transmitters

• Available in sizes 15 NB to 50 NB

• Material options: Carbon Steel (C.S.) & Stainless Steel (S.S.)

• Eliminates three major measurement inaccuracies seen in small orifice line installations

• No impulse tubing required – fewer leakage points

• Reduces startup time and improves reliability

Description

An Integral Orifice Plate Assembly (IOPA) is a compact and complete flow measurement device that mounts directly to the Differential Pressure Transmitter.
It eliminates the need for external impulse piping, reducing installation complexity and minimizing potential leak points.

The assembly includes:

• Integral orifice plate

• Body

• Studs & nuts

• Gaskets

The units are available with socket weld or threaded end connections, and can also be supplied with upstream & downstream piping with flanged ends as per requirement.
