Series RMV Rate-Master® Dial-Type Flowmeters

Rate-Master® Dial-Type Flowmeters
Brass Body; Three Ranges to 20 GPM Water

Brass Body; Three Ranges to 20 GPM Water

The SERIES RMV Rate-Master® Flowmeters measure higher water flow rates with ±2% of full scale accuracy at an affordable price. 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.
