ORIPAC Flow Measurement Systems have been designed for use wherever there is an application for a conventional flow orifice plate. They can also be used in place of other primary differential producers for efficiency and cost effectiveness. ORIPAC was designed and developed by engineers experienced in the differential flow measurement field. Standard size units available from stock and customized units are available to meet specific field requirements including flange rating, pipe schedule and differential pressure. Installation is accomplished simply by slipping the self-centering ORIPAC between standard flanges (orifice flanges are not required). The ORIPAC is available for all line sizes and fluids, and meets or exceeds AMSE, AGA and ISO standards.

The Model 2300 offers short laying length, easy installation, high accuracy, and very low permanent pressure loss. It is corrosion-resistant and carries minimal maintenance requirements, making it as economical as it is accurate and consistent. These low maintenance devices provide reliable performance and minimal headloss for a wide range of municipal and industrial applications. Made of dimensionally stable fiberglass-reinforced vinyl ester epoxy ensures accurate flow measurement and long life. Highly corrosion resistant, self-scouring, and accommodates a wide range of line fluids, line pressures and temperature conditions up to 350°F. The carbon steel holding flange is coated with vinyl ester epoxy and has 316 stainless steel pressure connections. The Model 2300 comes ready to install with neoprene flange gaskets to fit pipes from 3/4" to 120". It can be supplied with bronze, stainless steel, or other metal throat materials.

INDUSTRY-STANDARD TYPES and CUSTOM CONFIGURED ORIFICE PLATES to YOUR REQUIREMENTS. An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate). Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate.

Ring Type Joint (RTJ) orifice plates are recommended for clean liquids, gases and low velocity steam flows. RTJ orifice plates incorporate integral gaskets for installation between ring-type joint flanges. Based on proven technology, there are no moving parts and they are suitable for high-temperature and high-pressure applications. Plate thickness depends on line size and differential pressure and should be sufficient to prevent the plate from deforming under operating conditions. RTJ type orifice plates may be machined in one piece, or alternatively from two pieces, with an orifice plate screwed onto a carrier ring/gasket.

Universal Orifice Plates are fabricated for use with RTJ plate holders and are interchangeable with most orifice fittings. Each plate is carefully manufactured to meet or exceed AGA Report #3, ISA, and A.S.M.E. recommendations.
