Installation Requirements
Piping Condition
The installation of the vortex flowmeter requires a certain length of straight pipe section both upstream and downstream of the sensor. The common configurations are as follows (D represents the diameter of the pipe):
1.
The sensor should be installed on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that matches the sensor's diameter. Ensure that there is a straight pipe section length of 15-20D upstream and 5-10D downstream of the sensor.
2.
The pipe near the liquid sensor must be fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If not, use a slightly larger pipe with a diameter deviation of ≤3% and not exceeding 5mm. Avoid installing sensors in areas with strong electromagnetic interference, limited space, or difficult maintenance..
5.
Horizontal pipeline installation is the most common method for flow sensors. When measuring gas flow, if the gas contains a small amount of liquid, install the sensor at a higher point in the pipeline. When measuring liquid flow, if the liquid contains a small amount of gas, install the sensor at a lower point in the pipeline.
6.
For vertical pipeline installations measuring gas flow, the sensor can be installed without flow direction restrictions. If the gas includes a small amount of liquid, the flow should be from bottom to top. When measuring liquid flow, ensure the flow is from bottom to top to prevent additional weight on the probe.
7.
For horizontal pipelines, sensors can be side-mounted regardless of the fluid being measured, which is particularly suitable for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred if conditions permit, as it reduces the temperature impact on the amplifier.
8.
Inverted installation of sensors on horizontal pipelines is generally not recommended. It is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids, especially where frequent pipeline cleaning is required.
9.
When measuring high-temperature steam with insulated pipelines, ensure the insulation layer does not exceed one-third of the bracket height.
10.
For selecting pressure and temperature measurement points near the sensor, position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.
