Product Highlights

  • Easy to read design - The direct reading scales eliminate troublesome conversions
  • Special integral flow guides stabilize the float throughout the range to keep it from hunting or wandering in the bore
  • The float is highly visible against a white background
  • Construction assures accuracy - All Rate-Master® flowmeter bodies are injection molded of tough, clear, shatter-proof polycarbonate plastic around a precision tapered pin
  • The result is accurate and repeatable readings
  • The single piece plastic body is mounted to a stainless steel back bone into which pipe thread inserts are welded to absorb piping torque
  • Precision metering valves of brass or stainless steel (specify BV or SSV on order) are available as an optional extra and permit precise flow adjustments
  • For vacuum applications, Model RMA units are available with top mounted valves (specify TMV in the model number)
  • Installation is simple - The Rate-Master® flowmeter can be neatly through-panel mounted to keep flow tube centers in the same plane as the panel surface or surface mounted on the panel by means of tapped holes in the backbone
  • When through-panel mounted, the bezel automatically positions the instrument at the correct depth in the panel cutout
  • Surface mounted units can also be held in place by the piping
  • All mounting hardware plus installation and operating instructions are included
  • Easy-to-Interchange bodies - Within a given Series Rate-Master® flowmeter bodies can be instantly interchanged
  • Simply "unplug" the body from backbone and replace it with another
  • O-rings provide a tight seal on inlet and outlet
  • Piping remains undisturbed
  • Interchangeability is useful where different scale ranges are sometimes required at the same location in the laboratory or plant
  • Cleaning is easy - To release the plastic flowmeter body from the stainless steel backbone, just remove four screws
  • Pipe thread flow connections remain undisturbed
  • Remove the slide cover and the plug ball stop, clean the flow tube with soap and water and reassemble
