Installation Requirements
Piping Condition
The installation of the vortex flowmeter requires specific straight pipe sections both before and after the meter. The common configurations are as follows (D represents the pipe diameter):
1.
The sensor must be installed on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and has the same diameter as the sensor. There should be an appropriate length of straight pipe upstream and downstream of the sensor. The required lengths are 15-20D for the upstream straight pipe section and 5-10D for the downstream straight pipe section.
2.
The pipe near the sensor should be fully 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 match the sensor diameter as closely as possible. If an exact match is not achievable, use a slightly larger diameter pipe, ensuring the error is ≤3% and does not exceed 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, limited space, or where maintenance would be inconvenient. Installation Requirements.
5.
Horizontal pipeline installation is the most common method for flow sensors. For gas flow measurement, if the gas contains a small amount of liquid, install the sensor at a higher point in the pipeline. For liquid flow measurement, if the liquid contains a small amount of gas, install the sensor at a lower point in the pipeline.
6.
Sensor installation in vertical pipelines: For gas flow measurement, install the sensor on a vertical pipeline without flow direction restrictions. If the gas contains a small amount of liquid, the flow should be from bottom to top. For liquid flow measurement, the flow should also be from bottom to top to avoid additional weight on the probe.
7.
Side installation of sensors on horizontal pipelines: Sensors can be side-mounted on horizontal pipelines for any fluid, particularly for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred, if conditions permit, to minimize the temperature impact on the amplifier.
8.
Inverted installation of sensors on horizontal pipelines is generally not recommended. It is unsuitable for measuring general gases or superheated steam but can be used for saturated steam and high-temperature liquids or in situations requiring frequent pipeline cleaning.
9.
When installing sensors on pipelines with insulation layers for high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: Based on measurement requirements, if pressure and temperature need to be measured near the sensor, position the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream of the sensor.
