Installation Requirements
Piping condition
The installation of the vortex flowmeter necessitates a specified length of straight pipe sections both upstream and downstream, with the common configurations as follows (D represents the pipe diameter):
1.
The sensor must be mounted on pipes that are horizontal, vertical, or inclined (with liquid flowing from bottom to top) and match the sensor's diameter. Ensure the upstream straight pipe section is 15-20D and the downstream section is 5-10D.
2.
The pipe adjacent to the liquid sensor must be fully occupied by the measured liquid.
3.
Avoid installing the sensor on pipes subject to significant mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If identical diameters are unattainable, opt for a slightly larger pipe, maintaining an error margin ≤3% but not exceeding 5mm. Refrain from installing the sensor in areas with strong electromagnetic interference, cramped spaces, or where maintenance is cumbersome..
5.
Horizontal pipeline installation is the most prevalent method for flow sensors. For gas flows containing small liquid amounts, mount the sensor at a higher pipeline point. Conversely, if measuring liquid flows with minor gas content, install the sensor at a lower pipeline point.
6.
Vertical pipeline sensor installation: For gas flow measurements, vertical pipeline installation is acceptable regardless of flow direction. If the gas contains some liquid, ensure the gas flows from bottom to top. For liquid flow measurements, arrange the liquid flow from bottom to top to prevent additional weight on the probe.
7.
Side-mounted sensor installation on horizontal pipelines. This approach is suitable for any fluid, notably superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible as it reduces the amplifier's temperature exposure.
8.
Inverted sensor installation on horizontal pipelines is generally discouraged. It is unsuitable for general gases or superheated steam but can measure saturated steam, high-temperature liquids, or pipelines requiring frequent cleaning.
9.
Sensor installation on pipelines with insulation. For high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selection of pressure and temperature measurement points: To meet measurement requirements, position the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream.
