Installation Requirements
Piping Condition
For optimal performance, the installation of the High Accuracy Vortex Flowmeter for Steam requires certain straight sections of pipe both before and after the sensor. The common configurations are as follows (D represents the pipe diameter):
1.
Install the sensor on a horizontal, vertical, or inclined pipe (flow direction: bottom to top), ensuring the pipe diameter matches the sensor's. The pipe upstream should be 15-20D long, and downstream should be 5-10D to meet the necessary straight pipe requirements.
2.
The pipe near the liquid sensor should be completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations.
4.
Ensure the inner diameter of the straight sections closely matches the sensor's diameter. If the diameters cannot be identical, use a slightly larger pipe with an error margin of ≤3% and not exceeding 5mm. Avoid locations with strong electromagnetic interference, restricted spaces, or areas that are difficult to maintain..
5.
Horizontal pipeline installations are most common. For gas flow measurements, if the gas contains a small amount of liquid, install the sensor at a higher point. For liquid flow measurements, if the liquid contains a small amount of gas, install the sensor at a lower point in the pipeline.
6.
Vertical pipeline sensor installation: For gas flow, the sensor can be installed without regard to flow direction. If the gas contains liquid, the flow should be from bottom to top. For liquid flow, ensure the flow direction is from bottom to top to prevent excess weight on the probe.
7.
Side installation on horizontal pipelines: This method is suitable for measuring superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible to reduce temperature impacts on the amplifier.
8.
Inverted installation on horizontal pipelines is generally not advisable. It is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids or frequent cleanings.
9.
When installing sensors on pipelines with insulation layers for high-temperature steam, the insulation should not exceed one-third the height of the bracket.
10.
Selection of pressure and temperature measurement points: When necessary, the pressure measurement point should be 3-5D downstream, and the temperature measurement point should be 6-8D downstream of the sensor.
