Table 1 General characteristics
| Destined for the measurement of | Gas volume |
| Environmental classes | M1/E2 |
| Accuracy class | 0.5 |
| Operating pressure range for meters equipped with standard mounts | The spool piece and transducers may be used at a pressure between 7 and 425 bar(g). For this pressure range the flow characteristics as mentioned in table 2 are applicable. If the minimum pressure is between 3,5 and 7 bar(g), the values for $Q_{\mathrm{max}}$ have to be reduced to 50% of the values indicated in table 2. For T32 transducers only: if the minimum pressure is between 7 and 10 bar(g), the values for $Q_{\mathrm{max}}$ have to be reduced to 80% of the values indicated in table 2. If the minimum pressure is between 3,5 and 7 bar(g), the values for $Q_{\mathrm{max}}$ have to be reduced to 50% of the values indicated in table 2. The measuring range shall be 1:20 minimally. |
| Operating pressure range for meters equipped with Isolated Mounts on Chordal paths | The spool piece and transducers may be used at a pressure between: -0 and 105 bar(g) for meter size 4 to 12 inch. -8 and 105 bar(g) for meter size 14 to 42 inch. For these pressure ranges, the flow characteristics as mentioned in table 2 are applicable. If T200 transducers are used, they are always installed with their dedicated T200 isolated mounts for meter size 4 to 42 inch with a pressure range of 0 up to and including 259 bar. The flow characteristics as mentioned in table 2 are applicable. |

Notes:
If higher values are chosen for $ v_{\min} $ and/or lower values for $ v_{\max} $ it has to be taken into account that $ v_{\min}\leq0,05 $ $ v_{\max} $ and $ v_{t}\leq0,2 $ $ v_{\max}. $
The flow rates can be calculated as follows:
$$ Q = v \cdot \frac {1}{4} \cdot \pi \cdot D ^ {2} \cdot 3 6 0 0 $$
Where Q = flow rate $ [\mathrm{m}^{3} / \mathrm{h}] $ , v = velocity $ [\mathrm{m} / \mathrm{s}] $ , and D = diameter [m]
Meter type 3414,3415,3416 and 3417 can be manufactured from 4-42 inch.
Meter type 3418 can be manufactured from 8-42 inch.
