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.
Features
  • Rugged forged brass housing yields great compatibility and strength, allowing the unit to withstand system pressures to 1000 psig (68.9 bar)
  • Shatter proof construction, unlike glass tube variable area flowmeters, yields long operation life
