Installation Requirements
Piping Condition
The installation of the High Accuracy Steam Vortex Flowmeter requires specific straight pipe sections both before and after the sensor. The common configurations are as follows (D denotes the diameter of the pipe):
1.
The sensor should be mounted on a pipe that is horizontal, vertical, or inclined (with the fluid flowing from bottom to top) and matches the sensor's diameter. A certain length of straight pipe is essential upstream and downstream of the sensor, meeting the requirements of 15-20D for the front straight pipe section and 5-10D for the rear straight pipe section.
2.
The pipe near the liquid sensor should always be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subjected to strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should ideally match the sensor diameter. If an exact match is not possible, a slightly larger diameter pipe should be used, with an error margin of ≤3% and not exceeding 5mm. Also, avoid placing the sensor in areas with strong electromagnetic interference, restricted space, or where maintenance is inconvenient..
5.
Horizontal pipeline installation is the most common method for flow sensors. For gas flow measurements, if the gas contains a small amount of liquid, install the sensor at a higher point in the pipeline. For liquid flow measurements, if the liquid contains a small amount of gas, install the sensor at a lower point in the pipeline.
6.
For vertical pipeline installations, when measuring gas flow, the sensor can be installed on a vertical pipeline in any flow direction. If the gas contains a small amount of liquid, the gas should flow from bottom to top. For liquid flow measurements, the liquid should flow from bottom to top to avoid additional weight on the sensor probe.
7.
Side installation of sensors on horizontal pipelines. Regardless of the fluid type, sensors can be side-mounted on horizontal pipelines. This is particularly beneficial for measuring superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when conditions allow, as it minimizes the temperature effect on the amplifier.
8.
Inverted installation on horizontal pipelines is generally not recommended. It is unsuitable for measuring general gases or superheated steam. It can be used for measuring saturated steam and is ideal for high-temperature liquids or scenarios requiring frequent pipeline cleaning.
9.
For pipelines with insulation layers, particularly when measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
When selecting pressure and temperature measurement points near the sensor, the pressure measurement point should be 3-5D downstream of the sensor, while the temperature measurement point should be 6-8D downstream.
