ABB 10A6131AB1D1X0 Global Purgemaster Flowmeter

The ABB 10A6131AB1D1X0 Global Purgemaster Flowmeter is a compact glass-tube, variable-area rotameter designed for ultra-low purge gas flows, rated at 0.95 SCFH CL2 (318-2). It belongs to ABB's SNAP-IN small-flow Purgemaster family and installs inline with 1/4 in. NPT or G1/4 internal threads, with inline, front- and rear-panel mounting options. The wetted parts typically feature a 304 stainless steel body and Buna N O-rings, with a borosilicate glass measuring tube and a selection of float materials (including sapphire, carboloy, and tantalum) to suit different purge gases. Operating temperature ranges differ by connection material (0 to 120 C for stainless fittings and 0 to 95 C for brass fittings). Common applications include purge-gas delivery for analytical instruments and semiconductor equipment, where visible flow indication and low, stable flow are essential.
