ZFM digital mass flow meter
High accuracy aluminum or stainless steel thermal mass flow controllers
Downloads
ZFM are compact digital mass flow meters designed to measure flow rates of gases. Using thermal mass flow metering, these meters offers accuracy and high cost efficiency.
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.
| Accuracy | ±(0.5% RD + 0.2% FS) based on actual calibration (at calibration temperature and pressure). |
| Calibrations | Performed at standard conditions 101.4 kPa and 21.1 °C unless otherwise requested or stated. |
| Repeatability | ±0.15% of full scale. |
| Response Time | 2 secondes to within +/-2% of flow rate, over 25% to 100% full scale |
