Series RM Rate-Master Polycarbonate Flowmeter

Brand: Dwyer Instruments, LLC
Does not ship to VA, United States
The Series RM Rate-Master® Flowmeters are a line of general use, direct reading precision flowmeters suitable for both gas and liquid applications.

This Series consists of 2" (51 mm), 5" (127 mm) and 10" (254 mm) scales that can be panel or surface mounted with optional precision metering valves. 

Within a given Series, the Rate-Master® flowmeter bodies can be instantly interchanged, allowing the piping to remain undisturbed, interchangeability of the ranges, and easy cleaning.
Features
  • Direct reading scales eliminate the need for troublesome conversions
  • Stainless steel backbone absorbs piping torque reducing installation damage and cost
  • Shatter-proof polycarbonate allows for long operation life
  • Precision injection molding around a precision tapered pin enables high repeatability
  • Increased reading accuracy with special integral flow guides that stabilize float movement
  • Scale graduations on both side of the indicating tube allow for instantaneous flow reading saving time
