Dwyer Instruments PE-J-2 | PVC orifice plate flowmeter | 4" line size | 2.000" bore | 0.5 Beta | Water capacity: 100" d.p. W/C | 141.51 GPM flow; air capacity: 503.76 SCFM @ 14.7 psia | 810.06 SCFM @ 20 psig | 1507.64 SCFM @ 100 psig; 3 lb
The one-piece PVC structure of the Model PE-J-2 Orifice Plate Flowmeter has a special holder or carrier ring with integrated gaskets and metering taps. The Series PE is a real primary element that includes all of the necessary components for differential pressure measurement, in contrast to a normal orifice plate. It was intended to be used whenever a traditional flow orifice plate is needed. For efficiency and cost-effectiveness, it can also be utilized in place of other main differential producers. The Series PE is utilized for air and most gases and comes in line diameters ranging from 1/2" to 24". It satisfies or surpasses ISO, AGA, and ASME requirements.
