| 010 MASS FLOW METERS Alicat Scientific’s M Series Mass Flow Meters Ready in an Instant to Respond in 10 milliseconds or Less! The innovative features built into every Alicat mass flow meter are there to save you time and money. Unlike traditional mass flow meters, Alicat mass flow meters utilize laminar flow and differential pressure technology. The result is an extremely fast, accurate meter with no warm-up time and unparalleled versatility. Multi-gas Selectivity All Alicat flow meters come with Gas Select™. They are calibrated and ready for use with 20gases and 10gas blends. You select the gas via the display or through the RS-232 or RS-485 interface. See page 8 for gas list. In addition, Alicat can calibrate your meter for gas mixtures specific to your applications. High Accuracy and 200:1 Turndown Alicat mass flow meters have a standard accuracy of ± (0.8% of reading +0.2% of full scale). We also offer a high accuracy calibration of ± (0.4% of reading + 0.2% of full scale) for flow meters ranging from 5SCCM to 500SLPM with a 200:1 turndown. This makes it possible to use a single Alicat meter to measure an operating flow range that would
