What is an Integral Orifice Plate Assembly?
Flow measurement in pipelines is critical for various industrial processes. Arrotop’s Integral Orifice Assembly offers a precise and efficient solution for measuring fluid flow. By integrating the orifice plate with the measuring instrument, this assembly simplifies installation, improves accuracy, and reduces maintenance costs.
Product Data
The Arrotop Integral Orifice Assembly (ARO-OPA-IOA) is designed to provide accurate and reliable flow measurement for liquids, gases, and steam. This fully integrated flow meter eliminates the need for additional fittings, tubing, valves, adapters, and mounting brackets, thereby reducing welding and installation time. By directly mounting Differential Pressure Transmitters on the orifice assembly, installation costs and potential leak points are significantly reduced.
Direct Mounting Capability
The ARO-OPA-IOA Integral Orifice Assembly’s direct mounting capability allows for the easy attachment of Differential Pressure Transmitters via a Three/Five-Valve H-type manifold. This configuration streamlines the installation process and enhances measurement accuracy by eliminating potential sources of error associated with long impulse lines.
