Installation Requirements
Piping Condition
The installation of the High Accuracy Wear Resistant Vortex Flowmeter for Liquid and Gas requires specific straight pipe sections both before and after the device. The common configurations are as follows (D represents the diameter of the pipe):
1.
The sensor should be mounted on a horizontal, vertical, or inclined pipe (with the liquid flowing from bottom to top) that matches the sensor's diameter. It is critical to ensure there is a sufficient length of straight pipe both upstream and downstream of the sensor. The upstream straight pipe should be 15-20D, and the downstream should be 5-10D in length.
2.
The pipe near the liquid sensor must be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor's diameter. If achieving an exact match isn’t feasible, use a slightly larger diameter pipe with an error margin of ≤3% and not exceeding 5mm. The sensor should also be kept away from areas with strong electromagnetic interference, limited space, or where maintenance would be inconvenient..
5.
Horizontal pipeline installation is the most common method. For gas flow measurement, if the gas contains a small amount of liquid, the sensor should be installed at a higher point in the pipeline. Conversely, for liquid flow measurement, if the liquid contains a small amount of gas, the sensor should be installed at a lower point in the pipeline.
6.
Vertical pipeline sensor installation is feasible for gas flow measurement with no restriction on flow direction. If the gas contains some liquid, the flow should be from bottom to top. For liquid flow, install the sensor so that the flow is from bottom to top to avoid adding extra weight to the probe.
7.
Side installation on horizontal pipelines is suitable for all fluid types, including superheated steam, saturated steam, and low-temperature liquids. This method minimizes temperature impact on the amplifier and is preferred when conditions allow.
8.
Inverted installation on horizontal pipelines is generally not advisable. It is unsuitable for measuring general gases or superheated steam but can be used for saturated steam and high-temperature liquids where frequent pipeline cleaning is necessary.
9.
When measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height for effective sensor installation.
10.
For pressure and temperature measurement near the sensor, the pressure measurement point should be located 3-5D downstream of the sensor, and the temperature measurement point should be 6-8D downstream.
