Installation Requirements
Piping Condition
The installation of the Liquid Vortex Flowmeter requires a certain straight pipe section before and after the sensor, with common scenarios as follows (D represents the diameter of the pipe):
| Piping condition | upstream | Downstream |
| Concentric shrinkage pipe full open gate valve |
15D | 5D |
| ∠90° square elbow | 20D | 5D |
| Same plane 2∠90°elbow | 25D | 5D |
| Semi-open gate valve regulating valve | 50D | 5D |
| Different plane 2∠90°elbow | 40D | 5D |
| With rectifier tube bundle | 12D | 5D |
1.
The sensor must be installed on a horizontal, vertical, or inclined pipe (with the liquid flowing from bottom to top) that matches the sensor's diameter. Ensure a sufficient length of straight pipe upstream (15-20D) and downstream (5-10D) from the sensor.
2.
The pipe near the liquid sensor should always be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If not identical, a slightly larger diameter pipe may be used, with a deviation of ≤3% and not exceeding 5mm. Do not install the sensor in areas with strong electromagnetic interference, limited space, or where maintenance would be challenging..
5.
Horizontal pipeline installation is the most prevalent for flow sensors. For gas flow containing a small amount of liquid, place the sensor at a high point in the pipeline. For liquid flow containing a small amount of gas, position the sensor at a low point in the pipeline.
6.
Vertical pipeline sensor installation. For gas flow, the sensor can be installed without restriction on flow direction. If the gas contains a small amount of liquid, the flow should be from bottom to top. For liquid flow, ensure the flow is from bottom to top to avoid additional load on the probe.
7.
Side installation on horizontal pipelines. Sensors can be side-mounted, especially for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible as it reduces the temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is generally discouraged. It is unsuitable for measuring general gases or superheated steam but can be used for saturated steam and high-temperature liquids, particularly where frequent pipeline cleaning is required.
9.
For pipelines with insulation layers measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points. Depending on measurement needs, position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.
