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.
