RATE-MASTER® DIAL-TYPE FLOWMETER

FLOW

Brass Body, Three Ranges to 20 GPM Water, Shatterproof Construction

The Series RMV Rate-Master® Dial-Type Flowmeter measures higher water ow
rates with ±2% of full-scale accuracy at an affordable price. Stocked models are tted
with 1˝ female NPT inlet and outlet; 3/4˝ and 1/2˝ sizes are also available. Install in line,
supported by piping or ush panel mount with complete hardware package included.

FEATURES/BENEFITS

• 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 owmeters, yields long
operation life

APPLICATIONS

• Monitor coolant ow through ingot heaters, high-amp switchgear, resistance welders,
heat exchangers, compressors, scrubbers

• Monitor water consumption to different processes and operations for more efcient
operations

• Calculate required ll or drain times for tanks, water towers
