Product Description
Dwyer Rate-Master Variable Area Flowmeter with Stainless Steel Valve
The Dwyer RMA-25-SSV Variable Area Flowmeter (Rate-Master) features a 2" scale with stainless steel valve, designed for precise flow measurement of air and compatible gases/liquids. With a range of 10-100 LPM air (10,000-100,000 CC/min), this industrial flowmeter offers reliable performance with 4% accuracy and operating limits of 130°F temperature and 100 psi pressure.
Key Features & Benefits
  • Easy-to-read direct reading scales eliminate conversion calculations
  • Integral flow guides stabilize the float throughout the range to prevent hunting or wandering
  • Highly visible float against white background for clear readings
  • Injection molded polycarbonate body with precision tapered pin for accuracy and repeatability
  • Stainless steel backbone with welded pipe thread inserts to absorb piping torque
  • Optional precision metering valves in brass or stainless steel for flow adjustments
  • Simple installation with through-panel or surface mounting options
  • Interchangeable bodies within the same series for flexible range requirements
  • Easy cleaning process with removable flowmeter body
