Installation Requirements
Piping Condition
The installation of the vortex flowmeter necessitates a specific straight pipe section before and after the meter. The standard configurations are as follows (D represents the diameter of the pipe):
1.
The sensor must be mounted on a pipe that is horizontal, vertical, or inclined (with the liquid flowing upward) and matches the diameter of the sensor. Ensure a straight pipe length upstream and downstream of the sensor, with the front section requiring 15-20D and the rear section 5-10D.
2.
The section of pipe near the liquid sensor must be fully 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 not feasible, use a slightly larger diameter pipe with a maximum deviation of ≤3% and not more than 5mm. Do not place the sensor in areas with strong electromagnetic interference, restricted space, or where maintenance is difficult..
5.
Horizontal pipeline installation is the most prevalent for flow sensors. When measuring gas containing minor liquid amounts, position the sensor at a higher point in the pipeline. Conversely, when measuring liquid with minor gas content, install the sensor at a lower point.
6.
Vertical pipeline sensor installation: For gas flow, the sensor can be placed on a vertical pipeline without flow direction constraints. If the gas contains minor liquid, ensure the flow is from bottom to top. For liquid flow, maintain an upward flow to prevent adding weight to the probe.
7.
Side installation on horizontal pipelines: Suitable for measuring superheated steam, saturated steam, and low-temperature liquids. Side-mounting is preferred when possible, as it reduces temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines: Generally not advised for general gases or superheated steam but can be used for saturated steam and high-temperature liquids, especially where frequent pipeline cleaning is required.
9.
For high-temperature steam measurements on insulated pipelines, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selection of pressure and temperature measurement points: Depending on measurement needs, place the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.
