For the insertion type, the measuring range according to the general speed mode classification as follows:
a．0.3 ~ 3.0 m/s | b．0.3~ 5.0 m/s | c．0.3 ~ 10.0 m/s | d．0.3 ~ 15.0 m/s |
e．0.4 ~ 20.0 m/s | f．0.6 ~ 30.0 m/s | g． 1.0 ~ 50.0 m/s | h． 1.2 ~ 60.0 m/s |
Note: The above list is for user to choose. Please choose the moderate flow rate to save calibration costs. Special attention should be paid to the speed limit of flammable gas. We recommend users to choose c, d, e, f velocity profile.
For inline flowmeter(i.e. with sampling tube), flow range based on the diameter of flow pipe, selection table at below.
pipe DN | Selectable flow range |
| Prefer flow range | Maximum flow range |
| Nm3/h | Kg/h（ Air） | Nm3/h | Kg/h（ Air） |
15 | 1.9 ～ 19 | 2.3 ～ 23 | 0.4 ～ 40 | 0.5 ～ 48 |
20 | 3.4 ～ 34 | 4.1 ～ 41 | 0.7 ～ 70 | 0.8 ～ 84 |
25 | 5.3 ～ 53 | 6.4 ～ 64 | 1.1 ～ 110 | 1.3 ～ 132 |
32 | 8.7 ～ 87 | 10.5 ～ 105 | 1.7 ～ 170 | 2.0 ～ 205 |
40 | 13.6 ～ 136 | 16.4 ～ 164 | 2.7 ～ 270 | 3.3 ～ 325 |
50 | 21.2 ～ 212 | 25.5 ～ 255 | 4.2 ～ 420 | 5.1 ～ 506 |
65 | 35.8 ～ 358 | 43.1 ～ 431 | 7.2 ～ 720 | 8.7 ～ 867 |
80 | 54.3 ～ 543 | 65.4 ～ 654 | 11.0 ～ 1100 | 13.2 ～ 1325 |
100 | 85.0 ～ 850 | 102.3 ～ 1023 | 17.0 ～ 1700 | 20.5 ～ 2047 |
150 | 190.0 ～ 1900 | 228.8 ～ 2288 | 38.0 ～ 3800 | 45.8 ～ 4576 |
Note: 1. Flow range is reference to the gas of air and nitrogen . Other gas or not listed above please contact us for detail.
2. User need choose right pipe according to the relative flow range. Minimum and maximum are all measurable flow rate, the best measurable means the most accurate flow span. User can use commonly flow multiple 2 as full scale, please contact us if the full scale is overrun.
