ORIPAC Flow Measurement System

The ORIPAC Series is a complete orifice plate flow measurement package incorporating an orifice plate with a unique holder or carrier ring containing metering taps and integral gaskets.

  • ORIPAC Model 5300: Unitized Stainless Steel Construction
    For Water, Air, Steam, Corrosive Fluids, High-Pressure & High-Temperature Fluids
  • ORIPAC Model 4150: Fiberglass Ring with Stainless Steel Plate
    For Water, Air, & Gases
  • ORIPAC Model 4150-P: All PVC or CPVC Construction
    For Low Pressure Gases
  • ORIPAC Model 4150-T: All Teflon (PTFE) Construction
    For Corrosive Gases & Liquids

Venturi Flow Meters

Venturi Flow Metering Lambda Square offers two Venturi flow meter models – both in a complete range of sizes:

  • VENTURI MODEL 2300: Unitized Stainless Steel Construction
    Providing high metering accuracy and low permanent pressure loss.
  • VENTURI MODEL 2350: Fiberglass Ring with Stainless Steel Plate
    For flow metering with minimal head-loss and designed to fit when space is at a premium.

Orifice Plates – Paddle Types

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.

  • Materials available: 304 / 316 Stainless, MONEL, Exotics, Carbon Steel, Teflon, CPVC, and more
  • Available in RF (Raised Face) or RTJ (Ring Type Joint) configurations – Welding Neck / Slip-On / Threaded
  • Supplied with two 1/2″ NPT tappings in each flange
  • Lambda Square Orifice Flange Unions are fabricated to ASME B16.36 requirements
  • Our Orifice Flange Union kits are available ready-to-install, complete nuts, bolts, screws, and gaskets

Orifice Flanges

Orifice Flanges are used to meter the volumetric flow rate of liquids or gases utilizing tapped or welded meter connections. The two pipe taps are used to measure the pressure drop of the flow through an Orifice Plate.

  • Available in RF (Raised Face) or RJT (Ring Type Joint) configurations – Welding Neck / Slip-On / Threaded
  • Supplied with two 1/2″ NPT tappings in each flange
  • Lambda Square Orifice Flange Unions are fabricated to ASME B16.36 requirements
  • Our Orifice Flange Union kits are available ready-to-install, complete nuts, bolts, screws, and gaskets

Unlike a standard orifice plate, the ORIPAC is a true primary element and includes components for differential pressure measurement.
