Max-Trak Model 180 Industrial Mass Flowmeters and Controllers are now available with 316-stainless-steel (ANSI or DIN) flange mounting for gas flowrates up to 1,000 L/min with pipe sizes up to 1 in. The major design enhancement of Model 180 is the use of this firm’s Dial-A-Gas technology, which makes Max-Trak the industry’s only multi-gas capable mass flow controller, according to the manufacturer. The Model 180 has an accuracy within ±1% and repeatability within ±0.2%. Max-Trak can communicate to a user workstation via RS-232, RS-485 or one of four analog signals. Max-Trak is NEMA 6/IP67 rated, conforming to rigorous water-resistant requirements. Hall 10.1, Stand F20–G21 — Sierra Instruments, Inc., Monterey, Calif.
