About Dwyer Rate-Master Series RMA

The Dwyer Rate-Master series RMA flowmeter is a 2" scale air flow meter with 1/8" female NPT inlet and outlet connections for inline monitoring and measuring of air flow with an accuracy of + or – 4% of full scale. An integral flow guide stabilizes the float throughout the range for consistent readings. The flowmeter is made of injection molded polycarbonate around a precision tapered pin to maintain calibration, resist breakage, and provide a clear view of the scale. The body is mounted to a stainless steel back bone with welded pipe thread inserts to absorb piping torque during installation. The scale is epoxy-coated brushed aluminum with black graduations marked along both sides of the flow tube for distinct readings. Models are available for measuring air flow in scfh, lpm, or cc/min. Some models come with a brass or stainless steel metering valve for precise adjustment of air flow, or with a top-mounted valve for vacuum applications. Hardware is included for panel or surface mounting. This flowmeter is commonly used for measuring air flow in medical equipment, air samplers, gas analyzers, pollution monitors, chemical injectors, and cabinet purging equipment, among other devices.
