The Series RMVII Rate-Master® Dial-Type Flowmeter consists of a machined brass
meter body which is ideally suited for water ows with ±5% of full-scale accuracy. Body
design ts standard 4-1/2˝ mounting hole layouts per ANSI B40.1. Inlet and outlet
threads are standard 3/4˝ female NPT.
FEATURES/BENEFITS
• Unique construction fully isolates owing media from gage front for leak-proof
operation at pressures up to 3000 psig (206.7 bar)
• Target-type design combined with a damage resistant magnetic linkage, drive a
pointer over easy-to-read litho scale
• 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 efcient
operations
• Calculate required ll or drain times for tanks, water towers
