ZFM low cost aluminum or stainless steel digital thermal mass flow meters Design Features Multi-gas/Multi-range functionality up to 8 bar (currently for 6 gases) Standard accuracy ± (0.5% RD + 0.2% FS) based on actual calibration Supports up to 46 Engineering Units (including User-defined) Stores additional user- calibration table data for up to 10 gases Two programmable Totalizers indicate total gas quantity User-programmable Pulse Output (via SSR) High and low gas flow Alarm limits with preset delay interval One user-programmable solid-state relays with latch option Internal conversion factors for up to 26 gases Automatic sensor zero offset adjustment (via digital interface or local push button) Extensive Self- diagnostic with status LED or OLED (optional) indication Local 128 x 64 high contrast OLED (optional) graphic display with joystick control Description The ZFM is an intelligent “state-of-the-art” digital Mass Flow Meter. It is offered in “small footprint” aluminum or stainless steel versions. Running the free “ZFM Configuration Utility” software, the user can select different gas types and flow ranges on-site without disconnecting, within a few minutes. These meters facilitate lower ownership costs, by employing fewer units for multiple applications and saving on cost of calibrations.
