Aalborg Instruments’ ZFM Mass Flow Meters 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 laptop and running ZFM Configuration Utility software, users can select different gas types and flow ranges without removing the instrument from the installation.
ZFM design features include:
- Self-diagnostics with status LED or OLED (optional) indication
- Automatic sensor zero offset adjustment (digital interface or local push button)
- Digital interface (RS-232 or RS-485) test/configuration port (optional Modbus RTU with isolated RS-485 transceiver)
- Two programmable totalizers
- Full scale covered flow ranges from 3.5 sml/min to 10 sl/min in seven models
- Selectable analog 0-5 Vdc, 0-10 Vdc, or 4-20mA outputs
- Universal 14-24 Vdc power supply input
