ZFM Mass Flow Meters combine meter intelligence, user convenience, and outstanding flow performance. They are designed for multigas/multirange functionality up to 8 bar (currently 6 gases) and a standard accuracy of ± (0.5% RD + 0.2% FS) based on actual calibration.

 

By connecting the instrument to the RS232/RS485 port of a PC or laptop and running free ZFM Configuration Utility software, the user can select different gas types and flow ranges within a few minutes without removing the instrument from the installation.
