Orifice Plate

Orifice plate flow meters are differential pressure sensors for flow rate. Can be used with gases, liquids, corrosive, and high temperature fluids. Applications include steam flow, boiler feedwater, and fluid flow rates in building water lines. Designed for use wherever there is an application for a conventional flow orifice plate.

Series OP Orifice Plate Flowmeter

Stainless Steel for Use with Compatible Liquids and Gases

The Series OP Orifice Plate Flowmeter is a complete orifice plate flow metering package. It incorporates a stainless steel orifice plate with a unique holder or carrier ring containing metering taps and integral gaskets. 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. Installation is accomplished simply by slipping the unit between standard flanges (orifice flanges are not required). The Series OP is available in line sizes from 1/2" to 24" and can be used with compatible liquids and gases.

Product Applications

Fluid flow rates in building water lines
Boiler feedwater
Cooling water
Combustion or compressed air
Steam flow

Series PE & TE Orifice Plate Flowmeters

PVC or PTFE Orifice Plate

The Series PE is available in line sizes from 1/2" to 24" and used for air and most gases.

Series PE Orifice Plate Flowmeter - One-piece PVC Construction

Available for line sizes from 1/2" to 24", the Series TE orifice plate can be used with gases, liquids, corrosive, and high temperature fluids.

Series TE Orifice Plate Flowmeter - One-piece PTFE Construction

The Series PE Orifice Plate Flowmeter offers one-piece PVC construction incorporating a unique holder or carrier ring containing metering taps and integral gaskets. Unlike a standard orifice plate, the Series PE 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 Series PE is available in line sizes from 1/2" to 24" and used for air and most gases. It meets or exceeds ASME, AGA & ISO standards.

The Series TE Orifice Plate Flowmeter offers one-piece PTFE construction similar to the OP and PE Series orifice plates, which incorporate a unique holder or carrier ring containing metering taps and integral gaskets. Available for line sizes from 1/2" to 24", the Series TE orifice plate can be used with gases, liquids, corrosive, and high temperature fluids. The Series TE can be easily installed by slipping the unit between standard flanges (orifice flanges are not required). The Series TE was designed for use anywhere 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.
