Dwyer Instruments OP-P-1 Flowmeter

Dwyer Instruments OP-P-1 Flowmeter is a complete Series OP orifice-plate flowmeter package for differential flow measurement of compatible liquids and gases. The stainless steel plate, carrier ring, metering taps, and integral gaskets provide a practical installation between standard flanges.

Applications and selection

Select the OP-P-1 where a conventional orifice-plate primary flow element is needed for field or laboratory process measurement. Its simplified installation avoids dedicated orifice flanges, while the corrosion-resistant construction supports long-term service. Confirm line size, fluid compatibility, and operating conditions before ordering.
