The RFS Series Single Flowmeter Regulator models combine a single stage regulator with one (RWS Series) ) flowmeter. This product also utilizes Western's "pressure compensated" design for applications that require high flow rates, this design provides more consistent delivery pressure by minimizing fluctuation over a wide range of inlet pressures. Designed for users who require precise flows, this product is ideal for the professional welder, laboratory, or industrial process user. A high pressure gauge keeps the user informed of the cylinder's content.
