INSTALLATION PICTURE
TECHNICAL DATA
| Measuring principle | Gas flow measurement based on thermal dispersion technology without additional temperature and pressure compensation |
| Measured parameter | - Gas mass flow [kg/h] - Standard volumetric flow [Nm³/h] - Standard flow velocity [Nm/s] |
| Signal processing | Microprocessor based, fully digital signal processing |
| Measuring mode | Constant current or constant temperature principle Note: The measuring mode will be selected by our qualified technicians de-pending on the application requirements during calibration of the flow meter and may not be changed by the operator. |
| Calibration | Various calibration types VACOMASS® calibration available, depending on installation situation, incl. temperature compensation |
| Protection class | IP68 |
| Explosion proof versions | Depends on type of flow meter, ATEX (option only) |
| Ambient temperature | from -40°C to +80°C |
| Power supply | 18-36 VDC (power supply via standard supply units possible) |
| Power consumption | Max. 1.1 Watt |
| Reproducibility | electronics: 0.125% of reading |
| Measuring accuracy | Up to 1% of reading + 0.1% of full scale (depends on straight inlet/ outlet piping, installation details, calibration) |
| Measuring range (1.013 mbar, 0°C) |
0.46 - 46 Nm/s (Standard), 0.08 – 400 Nm/s (Option) N… Standard conditions according to DIN 1343 |
| Turn-down-ration | 10:1 to 100 : 1 |
| Display and Operation (optional) |
- 10 digits, alphanumerical LED-display for field indication of actual flow rate and total flow, integrated totalizer, easy programming of the flow meter with a magnetic pin, simple and logical menu for transmitter set-up for VACOMASS® flow meter SS and VACOMASS® flow meter AL (not available on type DIN AL) - Monitoring on a remote graphic display, mounted in a field cabinet VACOMASS® electronic (remote-version - electronics in a separate housing) or directly onto DIN-rails - Monitoring on a graphic display of the VACOMASS® flexcontrol |
| Signal output (isolated) |
- 1 x analog output: 4-20 mA, active load < 400 Ohm, 10 Bit resolution - 1 x impulse output: field selectable, max. 2 impulse/s - optional : for remote-versions of VACOMASS® electronic and flexcontrol: Modbus, Profibus DP, HART |
