Description

Dwyer SERIES RM RATE-MASTER® POLYCARBONATE FLOWMETER
2″, 5″ or 10″ Scale, Interchangeable Bodies*

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. *The Rate-Master® flowmeter bodies can be instantly interchanged within the same series scale size, allowing the piping to remain undisturbed, interchangeability of the ranges, and easy cleaning.

NOTE: Effective immediately, the brass valve (-BV) option has been discontinued and the stainless steel valve (-SSV) is the suggested replacement.

Features:

  • Eliminate the need for troublesome conversions with direct reading scales
  • Reduce installation damage and cost due to stainless steel backbone that absorbs piping torque
  • Long operation life with durable, shatter-proof polycarbonate body
  • High repeatability enabled by precision injection molding around a precision tapered pin
  • Increased reading accuracy with special integral flow guides that stabilize float movement
  • Save time with instantaneous flow reading from scale graduations on both sides of the indicating tube

Applications:

  • Medical equipment
  • Air samplers
  • Gas analyzers
  • Pollution monitors
  • Chemical injectors
  • Cabinet purging
