| Use Annubar flowmeter in large caliber flow |
| 2011-5-24 16:53:47 |
Features of large flow measurement:
1, large diameter, straight pipe section is often difficult to guarantee
2. Low static pressure and low flow rate, often only allow small pressure loss
3. The range of flow velocity is large, requiring a large range of instrument
4. High fluid temperature
5. After the temperature of some flue gas decreases, the humidity rises, even with liquid
With reference to the above characteristics, the main advantages and disadvantages of Annubar flowmeters in applications are summarized.
The specific advantages have been introduced to you in the previous section. Below we mainly introduce the shortcomings of the Annubar flowmeter in the field and the points that need attention:
The first is what we need to pay attention to when applying:
The key when Annuba flowmeter is applied in the field is to prevent the impulse pressure pipe from being gambled by water droplets, and this problem has been overcome by our company, which is to change the positive and negative cut-off valves to pass through larger straight-through gate valves, followed by For on-site large-caliber and small-flow measurement , a differential pressure transmitter with good zero stability should be selected.
Second is the deficiency:
When the fluid composition changes, the density changes correspondingly, causing the displayed value to change; when the relative flow rate is small, the error is large.
