According to Aalborg Instruments, the ZFM Mass Flow Meters combine meter intelligence, user convenience, and outstanding flow performance.
They are designed for multi-gas/multi-range functionality up to 8 bar (currently 6 gases) and 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 lap-top 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.
