Installation Requirements
Piping Condition
The installation of the Wear Resistant Gas Vortex Flowmeter with High Accuracy Performance requires a specific straight pipe section before and after the sensor. The common scenarios are as follows (D represents the diameter of the pipe):
1.
The sensor should be mounted on a pipe that is either horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and has the same diameter as the sensor. Essential straight pipe lengths are required upstream and downstream of the sensor: 15-20D for the front straight pipe section and 5-10D for the rear straight pipe section.
2.
Ensure the pipe near the liquid sensor is fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes with strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If they are not the same, a slightly larger diameter pipe should be used, with an error margin of ≤3% and not exceeding 5mm. The sensor should not be installed where there is strong electromagnetic interference, limited space, or difficult maintenance access..
5.
Horizontal pipeline installation is the most typical method for flow sensors. When measuring gas flow with a small amount of liquid, the sensor should be placed at a higher point in the pipeline. Conversely, when measuring liquid flow with some gas content, the sensor should be installed at a lower point in the pipeline.
6.
Vertical pipeline installation of the sensor is feasible. For gas flow measurement, the sensor can be installed at any point in the vertical pipeline with no flow direction restrictions. If the gas contains a small amount of liquid, the flow should be bottom to top. For liquid flow, it should also be bottom to top to prevent additional weight on the probe.
7.
Side installation on horizontal pipelines is possible for all fluid types, especially superheated steam, saturated steam, and low-temperature liquids. This method is preferred if conditions allow as it reduces the temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is generally not recommended. While not suitable for general gases or superheated steam, it can be used for saturated steam and high-temperature liquids, or in scenarios requiring frequent pipeline cleaning.
9.
For pipelines with insulation layers, especially when measuring high-temperature steam, the insulation should not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points is critical. For accurate readings, position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.
