Azbil CMS Gas Mass Flow Meter for Hydrogen and Helium Gases incorporates a thermal microflow sensor developed by Azbil Corporation built with micro-machining and thin-film technologies. By integrating this sensor with advanced channel design technology, it was possible to achieve new levels of accuracy and measurement range at a low price. Because the CMS is a mass flowmeter, its measurements are not affected by temperature or pressure. High accuracy of ± 5% rdg. and high resolution. Analog output signals can be switched among 0 - 5 V, 1 - 5 V, and 4 - 20 mA by the keys. The CMS' functions include instantaneous flow rate indication, totalized or reverse-totalized flow display, event output, totalizer pulse output, totalized flow reset input, output scaling, gas type switching, etc. for a variety of applications.
