Description
Dwyer RMB-54D-SSV 20-200 SCFH SS Air Flow Meter 100 PSI Needle Valve Made in USA
The Dwyer RMB-54D-SSV is a variable area flow meter (rotameter) designed to measure air and compatible gas flow rates in the 20–200 SCFH range. It features a clear acrylic tube body mounted on a stainless steel manifold, with an integral needle valve for direct flow adjustment. The meter reads on a dual scale — SCFH on the top row and l/min on the bottom — allowing use with either unit convention without conversion. Dwyer Instruments manufactures this meter in Michigan City, Indiana, USA.

Applications
Variable area flow meters of this type are standard instruments for monitoring and controlling gas flow in industrial processes, laboratory gas distribution systems, clean room environments, and compressed air lines. The RMB series with stainless steel fittings and a 100 PSI pressure rating is suited for applications where corrosion resistance or contact with mildly aggressive media is a consideration — such as purge gas systems, gas sampling, and process equipment that requires a direct reading of flow rate at the point of use. The integral needle valve allows a single instrument to both measure and regulate flow, making these meters a common choice for instrumentation panels, gas manifolds, and bench-top gas supply setups. Dwyer's RMB series has been a workhorse rotameter line in industrial instrumentation for decades and remains in wide use today.
This Dwyer RMB-54D-SSV 20-200 SCFH stainless steel variable area flow meter is in good used condition. The acrylic tube body is clear with no visible cracks or crazing, and the dual SCFH/l/min scale is clean and legible. The stainless steel fittings and manifold base show minor surface wear consistent with normal use. It was pulled from a working environment where it was previously in service.
