Installation Requirements
Piping Condition
To ensure optimal performance, the installation of the vortex flowmeter mandates a specific straight pipe section before and after the device. The common scenarios are as follows (where D is the diameter of the pipe):
1.
The sensor should be installed on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and share the same diameter as the sensor. Ensure a straight pipe section of 15-20D length upstream and 5-10D length downstream of the sensor.
2.
The pipe adjacent to the liquid sensor should be fully filled with the liquid being measured, ensuring accurate readings.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations to maintain measurement accuracy.
4.
Ensure the inner diameter of the straight pipe section closely matches the sensor diameter. If exact matching isn't feasible, opt for a slightly larger diameter pipe with an error of ≤3% and not exceeding 5mm. Do not install the sensor in areas with strong electromagnetic interference, limited space, or where maintenance is inconvenient..
5.
Horizontal pipeline installation is the most common setup for flow sensors. For gas flow measurements, if the gas contains a small amount of liquid, position the sensor at a higher point in the pipeline. For liquid measurements, if the liquid contains a small amount of gas, position the sensor at a lower point in the pipeline.
6.
Vertical pipeline sensor installation: For gas flow measurements, the sensor can be installed on a vertical pipeline without flow direction restrictions. If the gas contains a small amount of liquid, the gas flow should be from bottom to top. For liquid flow measurements, ensure the liquid flows from bottom to top to avoid additional weight on the probe.
7.
Side installation of sensors on horizontal pipelines is viable for all fluid types, especially superheated steam, saturated steam, and low-temperature liquids. This method is preferred as it minimizes the temperature impact on the amplifier.
8.
Inverted installation of sensors on horizontal pipelines is generally not recommended. This method is unsuitable for general gases or superheated steam, but can be used for measuring saturated steam and high-temperature liquids, or in scenarios requiring frequent pipeline cleaning.
9.
For pipelines with insulation layers measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height to maintain sensor efficiency.
10.
Pressure and temperature measurement points should be selected based on specific requirements. Position the pressure measurement point 3-5D downstream of the sensor, and the temperature measurement point 6-8D downstream of the sensor for accurate readings.
