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.
