The Orifice Plate Holder, manufactured by Metroval, is a highly reliable differential pressure flow measurement device, developed in accordance with the international standards AGA 3, ISO 5167 and ASME B16.36. Designed for industrial applications and measurement systems, it provides high accuracy in gas flow measurement, it facilitates the operation, inspection and verification of data directly at the point of measurement, combining robustness and operational safety.
In the Double Chamber version, the equipment uses a system of isolated chambers that allows the safe movement of the orifice plate between the process line and the upper chamber, enabling its inspection or replacement without the need to interrupt the flow of the pipe.
Metroval plate holders are manufactured from ASTM certified materials, including Carbon Steel (A216 WCB/WCC / A352 LCC), Stainless Steel (A351 CF8M/CF3M) and Duplex / Super Duplex steels, with 316 Stainless Steel internal components. Designed to operate in pressure classes from 150# to 2500# per ASME standard, and up to 10,000# per API 6A, they serve pipe diameters from 2″ to 30″. Equipment can be supplied in accordance with NACE specifications for corrosive fluid (H2S) services. Pressure taps can be configured as threaded, welded, flanged or integrated, making it a robust and versatile solution for refineries, offshore platforms and pipelines.
Its great differential is the Guide System, a high-precision guide system that ensures perfect alignment and centeredness of the plate throughout the operation, ensuring stable, repeatable measurements and in compliance with metrological requirements. The equipment also incorporates a central operating manifold with integrated pressure gauge and built-in drive shafts, allowing operation on both sides and providing greater ergonomics, safety and ease of operation.
