Foxboro provides an orifice assembly to meet your process requirements by offering both compact and integral flow orifice assemblies.

The compact orifice is a wafer body orifice plate that includes an integral three-valve manifold. This one-piece unit mounts directly to a differential pressure transmitter. An alignment ring and optional installation kit provide the hardware necessary to properly install the orifice in various pipeline sizes having ANSI® or DIN flanges.

The Integral Flow Orifice Assemblies (IFOA) adapt electronic and/or pneumatic d/p cell transmitters for measuring small flow rates.

Features:

• Compact Orifice: suitable for use in liquid, gas or steam services
• Compact Orifice: rugged, integral construction
• Compact Orifice and calibrated transmitter are factory assembled
• IFOA: very high accuracy when equipped with associated piping
• IFOA: use with any differential pressure transmitter having standard process connections
• IFOA: process-wetted materials are available for use with both corrosive and noncorrosive fluids
