Installation Requirements
Piping condition
The installation of the Low Pressure Loss Anti Vibration Steam Vortex Flowmeter for Liquids requires specific straight pipe sections before and after. The common requirements are illustrated below (D represents the diameter of the pipe):
1.
Install the sensor on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and matches the sensor's diameter. Ensure a sufficient length of straight pipe both upstream and downstream of the sensor, with the front section requiring 15-20D and the rear section requiring 5-10D.
2.
Ensure the pipe near the liquid sensor is filled with the liquid being measured.
3.
Avoid installing the sensor on pipes experiencing strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If a match isn't possible, use a slightly larger diameter pipe with an error margin of ≤3% and not exceeding 5mm. Do not install the sensor in areas with strong electromagnetic interference, cramped spaces, or where maintenance would be inconvenient..
5.
Horizontal pipeline installation is the most commonly used method. For gas flow measurement, install the sensor at a higher point if the gas contains a small amount of liquid. For liquid flow measurement, position the sensor at a lower point if the liquid contains a small amount of gas.
6.
Vertical pipeline sensor installation. For gas flow, the sensor can be installed on a vertical pipe without flow direction restrictions. If the gas contains a small amount of liquid, ensure the gas flows from bottom to top. For liquid flow, the liquid should flow from bottom to top to avoid additional weight on the probe.
7.
Side installation on horizontal pipelines. Regardless of the fluid type, sensors can be side-mounted on horizontal pipelines. This method is especially advantageous for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred where possible to minimize temperature impacts on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally not recommended. 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, especially when dealing with high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Locating pressure and temperature measurement points. Depending on measurement requirements, the pressure measurement point should be 3-5D downstream of the sensor, while the temperature measurement point should be 6-8D downstream.
