Table 2 gives an overview of the general characteristics of the family of instruments.
The construction of the measuring instrument is recorded in the Documentation folder no. T10586-1.
Table 1 General characteristics
| Destined for the measurement of | Gas volume | |
| Environmental classes | M1/E2 | |
| Accuracy class | 0.5 | |
| Working pressure | The meter is either programmed with a density and viscosity setting, corresponding to the applied gas at preset pressure or using live pressure value from the optional pressure sensor. When using a preset value the maximum operating range for pressure $ p_{\mathrm{max}}/p_{\mathrm{min}} $ is 6,25 symmetrically divided around the preset pressure. | |
| Gas temperature range | -40-+100℃ gas meter-30-+80℃ gas meter with EVCD | |
