Dwyer Series RMV

Series RMV Rate-Master® Dial-Type Flowmeter

Brass Body; Three Ranges to 20 GPM Water

The Dwyer Series RMV Rate-Master® Flowmeters measure higher water flow rates with ±2% of full scale accuracy at affordable prices. Rugged forged brass housing is standard on all models for great compatibility and the strength to withstand system pressures to 1000 psig (68.9 bar). Unlike glass tube rotameters, these units won’t shatter and they work fine with even dark and/or opaque liquids. Stocked models are fitted with 1″ female NPT inlet and outlet; 3/4″ and 1/2″ sizes are also available. Install in line, supported by piping or flush panel mount with complete hardware package included.

Product Applications

Monitor coolant flow through ingot heaters, high-amp switchgear, resistance welders, heat exchangers, compressors, scrubbers.Monitor water consumption to different processes and operations for more efficient operation.Calculate required fill or drain times for tanks, water towers.
