ABOUT THE ORIPAC MODEL 4150-P

The ORIPAC is a complete orifice plate flow metering package. It offers one piece construction incorporating the orifice plate with a unique holder or carrier ring containing metering taps and integral gaskets. Unlike a standard orifice plate, the ORIPAC is a true primary element including the various components for differential pressure measurement.

It was designed for use wherever there is an application for a conventional flow Orifice plate. It can also be used in place of other primary differential producers for efficiency and cost effectiveness. The ORIPAC was designed and developed by leading authorities in the d/p flow measurement field. Installation is accomplished simply by slipping the unit between standard 125# / 150# flanges.

The ORIPAC is available in all line sizes for use with air and most gases. It meets or exceeds ASME, AGA & ISO standards.

FEATURES

BENEFITS

Unitized Type 1 or 2 PVC construction Simplifies installation - lower installed costs than traditional orifice mounting.
Integrated metering taps properly located and predrilled Used with standard ANSI flanges - orifice flange unions eliminated. No drilling/tapping pipe.
Full faced integral gaskets pre-attached. Precludes potential alignment problems during installation.
Self-centering within standard flanges. Oripac O.D. sits snug within bolt circle of specified flange rating insuring concentricity - centering devices or additional components eliminated.
"Corner" type metering taps. Established coefficient accuracy values.
Type 1 or 2 PVC Standard, CPVC, Teflon and other options available Use or superior high-tech materials eliminating rusting and plugging of sensing ports.
Custom Manufacture (able to meet corrosive and hi temp requirements). Standard configurations available from stock, custom units available in different materials, thickness and configuration to meet specific requirements for harsh applications.
Proven through a wide and varied range of applications and installations since 1984. Twenty (20) year history of reliability and accuracy
Sized for specific pipe schedules or special inside pipe diameters to match ducting, fiberglass, HDPE, etc. Insures accuracy by eliminating pipe inside diameter to Oripac inside diameter mismatches.
Available with any bore size to produce any specific differential pressure. Ability to match range on an existing d/p transmitter or indicating gage without recalibration or replacement.
Orifice bore calculated to match specified "headloss" requirements. Exact differential pressure values and overall system head loss can be calculated and pre-determined.
Orifice bore styles available include Concentric, Eccentric, Segmental, Quadrant edge, multiple bore. Able to address challenging flow applications including: low viscosity fluids, gasses containing liquids, limited pipe runs, etc.
Drain hole at bottom or vent hole at top available for orifice plate. Additional tap can be installed for drainage purposes. Gas with liquid buildup may require a drain at bottom of orifice to allow passage of condensate. Air in liquid lines may require a vent hole at top of orifice.
Bi-directional flow capabilities. Orifice plate available without bevel to accommodate flow in both directions.
Orifice plate thickness option. Thickness of orifice plate provided according to ASME/AGA specs standard. Can be provided with special plate thickness to address high pressure lines, etc.
Available for standard flange ratings (125/150#, 250/300#) DIN Ratings or custom flange requirements Eliminate potential flange rating mismatches, no need for additional centering devices.
Ideal for light weight duct measurement. Mounts between thin angle or plate flanges for lightweight installation.
Can be sized for restriction or pressure drop control in conjunction with flow measurement. Eliminate additional throttling valve by combining flow meter and restrictor as one integral unit.
Port size (Pizometer through hole) can be increased if required. Reducing the chance of plugging in lines containing particulates, solids, etc.
Metering Taps drilled "straight through" to the pipe I.D. Easily cleaned using pipe cleaner or rod out kit.
Can be used with Lambda flange mount bracket for installing instrumentation. Option for direct mount installation of manifold transmitter or indicating gage. (Remote mount also available)
Pre-attached nameplate. Serial #, Tag #, ID, Bore and other information available. Also available as SS attachment with ss wire.
Flexible readout options. Can be used with any Transmitter, Gage, Manifold arrangement.
Standard valve kit available. Includes nipples and shutoff valves to streamline installation.
