Installation Requirements
Piping Condition
For optimal performance, ensure a certain straight pipe section before and after the installation of the vortex flowmeter. The standard configurations are as follows (D represents the pipe diameter):
1.
Install the sensor on a horizontal, vertical, or inclined pipe (with the liquid flowing from bottom to top) matching the sensor's diameter. Ensure straight pipe sections upstream and downstream of the sensor, with lengths of 15-20D and 5-10D respectively.
2.
Ensure the pipe near the liquid sensor is fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes with significant mechanical vibrations.
4.
The inner diameter of the straight pipe should align closely with the sensor diameter. If not, use a slightly larger diameter pipe with a deviation of ≤3% and no more than 5mm. Avoid areas with strong electromagnetic interference, limited access, or difficult maintenance..
5.
Horizontal pipeline installation is most common. For gas flow with minor liquid content, mount the sensor at a higher pipeline point. For liquid flow with minor gas content, install at a lower point.
6.
Sensor installation on vertical pipelines should have unrestricted flow direction for gas. For gas with minor liquid content, flow should be bottom to top. For liquid flow, ensure bottom to top direction to prevent additional probe weight.
7.
Side installation on horizontal pipelines suits all fluids, especially superheated steam, saturated steam, and low-temperature liquids. This method reduces temperature impact on the amplifier and is preferred if conditions allow.
8.
Inverted installation on horizontal pipelines is generally discouraged. It is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids, or for pipelines requiring frequent cleaning.
9.
For high-temperature steam pipelines, ensure the insulation layer does not exceed one-third of the bracket height.
10.
For pressure and temperature measurement, position the pressure point 3-5D downstream and the temperature point 6-8D downstream of the sensor, depending on measurement requirements.
