 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.
Series PE:
• Mounted with standard flanges
• Standard "corner tap" configuration
• Corrosion free material
• Simplified installation
• Built in metering taps (1/4" female NPT STD)
• Proven through a wide range of applications for accuracy and energy efficiency
• Assures long term reliability and accuracy
 
Series TE:
• Excellent chemical resistance
• Weather resistant
• Flame retardant (without factory gaskets)
• Low friction (minimum wear)
• Orifice plate thickness 1/4" offering greater stability
Weight:Varies with line size. See Catalog page.
Pipe Requirements:General requirements 10 diameter upstream and 5 diameter downstream.
Installation:Standard flange 125#/150# rating.
Process Connections:1/4" female NPT.
Line Sizes:1/2" to 24".
Head Loss:1 - Beta ratio², eg: 1 - 07² = 1 - 0.49 = 51% of the d.p.
