Installation Requirements
Piping condition
For optimal performance, the installation of the vortex flowmeter necessitates a specific length of straight pipe section both before and after the sensor. The common scenarios are as follows (D represents the diameter of the pipe):
1.
The sensor should be installed on a pipe that is horizontal, vertical, or inclined (with liquid flowing from bottom to top) and matches the sensor's diameter. Ensure a straight pipe section of 15-20D upstream and 5-10D downstream of the sensor for accurate measurements.
2.
Ensure that the pipe near the sensor is completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations to maintain accuracy.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If a match is not possible, use a slightly larger diameter pipe with an error of ≤3% and not exceeding 5mm. Avoid locations with strong electromagnetic interference, limited space, or inconvenient maintenance..
5.
Horizontal pipeline installation is most common. For gas flow with liquid traces, install the sensor at a higher point. For liquid flow with gas traces, install at a lower point in the pipeline for best results.
6.
For vertical pipelines, install the sensor with no restriction on gas flow direction. If the gas contains liquid, ensure gas flows from bottom to top. For liquid flow, maintain bottom-to-top flow to avoid additional probe weight.
7.
Side-mounting the sensor on horizontal pipelines is effective for superheated steam, saturated steam, and low-temperature liquids. Side installation minimizes the temperature impact on the amplifier and is highly recommended when conditions permit.
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 pipelines requiring frequent cleaning.
9.
When measuring high-temperature steam using pipelines with insulation layers, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points is crucial. Place the pressure measurement point 3-5D downstream of the sensor, and the temperature measurement point 6-8D downstream to ensure precise readings.
