Series RMVII Rate-Master Dial Type Flowmeter

Brand: Dwyer Instruments, LLC
Request Information
Does not ship to United States
The Series RMVII Rate-Master® Flowmeters consists of a machined brass meter body which is ideally suited for water flows with ±5% of full scale accuracy.

Body design fits standard 4-1/2" mounting hole layouts per ANSI B40.1. Inlet and outlet threads are standard 3/4" female NPT.
Features
  • Unique construction fully isolates flowing media from gauge 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 flowmeters, yields long operation life
