Dwyer RMA-44-SSV Rate-Master Flowmeter 4-34 GPH Water 100 PSI 130°F 2in Scale

Dwyer RMA-44-SSV Rate-Master Flowmeter 4-34 GPH Water 100 PSI 130°F 2in Scale

The Dwyer RMA-44-SSV is a variable-area inline flowmeter from the Rate-Master RMA Series, calibrated for water service with a measurement range of 4 to 34 GPH on a 2-inch scale. It features a clear acrylic body for direct visual flow reading and an integral stainless steel needle valve for flow adjustment at the outlet end. The float position against the graduated scale gives an immediate, direct reading without any external power or electronics required.

Applications

The Dwyer RMA Rate-Master series is a widely used line of direct-reading variable-area flowmeters (rotameters) found throughout industrial, laboratory, and process control settings. The RMA-44-SSV is suited for monitoring and controlling water flow in cooling circuits, chemical dosing lines, HVAC systems, laboratory water supply manifolds, and light process piping where a simple, reliable visual flow indication is needed. The stainless steel needle valve version (SSV suffix) allows flow adjustment at the meter itself, making it a convenient single-device solution for both measurement and regulation. The acrylic body construction makes these meters particularly well-suited for clean water and mild fluid service at moderate pressures and temperatures. Dwyer Rate-Master meters have been a standard choice for OEM equipment builders and plant maintenance applications for decades and remain in wide use today.
