Installation Requirements
Piping condition
The installation of the vortex flowmeter necessitates a specific straight pipe section both upstream and downstream. The common configurations are as follows (D represents the pipe diameter):
1.
The sensor should be mounted on a pipe that is horizontal, vertical, or inclined (with the liquid flowing upwards). Ensure the pipe matches the sensor diameter. Maintain a straight pipe length of 15-20D upstream and 5-10D downstream of the sensor.
2.
The pipe adjacent to the liquid sensor must be filled with the measured liquid.
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. If not, use a slightly larger diameter pipe with an error margin of ≤3% and no more than 5mm. Refrain from installing the sensor in areas with strong electromagnetic interference, limited space, or difficult maintenance conditions. Installation requirements.
5.
Horizontal pipeline installation is the most common method for flow sensors. For gas flow measurements, if a small amount of liquid is present, install the sensor at a higher point in the pipeline. For liquid flow measurements, if a small amount of gas is present, install the sensor at a lower point in the pipeline.
6.
Sensor installation in vertical pipelines. For gas flow measurements, the sensor can be installed on a vertical pipeline regardless of flow direction. If a small amount of liquid is present in the gas, the flow should be from bottom to top. For liquid flow, the flow should be from bottom to top to avoid adding weight to the probe.
7.
Side installation of sensors on horizontal pipelines. Sensors can be side-mounted on horizontal pipelines for any fluid, particularly with superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible to reduce temperature impact on the amplifier.
8.
Inverted installation of sensors on horizontal pipelines is generally not recommended for common gases or superheated steam. It is suitable for saturated steam and high-temperature liquids or scenarios requiring frequent pipeline cleaning.
9.
When installing sensors on pipelines with insulation layers measuring high-temperature steam, the insulation should not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points. Based on measurement needs, place the pressure measurement point 3-5D downstream of the sensor, and the temperature measurement point 6-8D downstream.
