Sierra Instruments' Max-Trak Model 180 industrial mass flow meters and controllers feature 316 stainless steel (ANSI or DIN) flange mounting for gas flow rates up to 1000 SLPM (pipe sizes up to 1 in). The devices incorporate Dial-A-Gas technology, which makes the controller multigas capable. Accuracy is ±1% of full scale, and repeatability is ±0.2% of full scale. Stability is enhanced by an inherently linear body design, advanced platinum sensor technology, and a valve that is strong, flexible, and forgiving. The system can communicate to a user workstation via RS-232, RS-485, or one of four analog signals.
