SteelMass 640S Mass Flow Meter
Sierra Instruments’ Steel-MassTM Model 640S immersible thermal mass flow meter is designed for the toughest industrial gas flow measurement applications.
The versatile microprocessor-based transmitter integrates the functions of flow measurement, flow-range adjustment, meter validation and diagnostics in either a probe-mounted or remote housing. Mass flow rate and totalized flow, as well as other configuration variables, are displayed on the optional 2 x 12 LCD display. The programmable transmitter is easily configured via an RS-232 communication port and FLOWMETH's and Sierra's Smart InterfaceTM software, or via the display and magnetic switches on the instrument. FLOWMETH's and Sierra's state-of-the-art calibration facility insures that the calibration will match the application, and our patented Dry- SenseTM thermal sensor insures the Model 640S will hold this calibration over time. Our Smart InterfaceTM software guides you through a procedure to fully validate instrument performance, thus field-verifying meter functionality. The meter is available with a variety of input power, output signal, mounting and packaging options.
