1. Reasonably choose the installation site and environment.

Avoid strong electrical equipment, high-frequency equipment, and strong power switch devices; Avoid the influence of high temperature heat sources and radiation sources, avoid strong vibration areas and corrosive environments, and consider easy installation and maintenance.

2. There must be sufficient straight pipe sections upstream and downstream.

If there are two 90 ° elbows on the same plane upstream of the sensor installation point, then: the upstream straight pipe section is ≥ 25D, and the downstream straight pipe section is ≥ 5D.

If there are two 90 ° elbows on different planes upstream of the sensor installation point, then: the upstream straight pipe section is ≥ 40D, and the downstream straight pipe section is ≥ 5D.

The regulating valve should be installed 5D downstream of the sensor. If it must be installed upstream of the sensor, the upstream straight pipe section of the sensor should not be less than 50D, and the downstream should not be less than 5D.

3. The piping upstream and downstream of the installation point should be concentric with the sensor, and the coaxial deviation should not be less than 0.5DN.

4. The pipeline adopts vibration reduction measures.

Sensors should be avoided as much as possible from being installed on pipelines with strong vibrations, especially lateral vibrations. If installation is necessary, vibration reduction measures must be taken by installing pipeline fastening devices and adding anti vibration pads at the upstream and downstream 2D positions of the sensor.

5. Installing a flow sensor on a horizontal pipelineThe installation method.

When measuring gas flow, if the measured gas contains a small amount of liquid, the sensor should be installed at a higher position in the pipeline.

When measuring liquid flow rate, if the measured liquid contains a small amount of gas, the sensor should be installed at a lower part of the pipeline.

6. Installation of sensors in vertical pipelines.

When measuring gas flow, the sensor can be installed on a vertical pipeline with no restrictions on the flow direction. If the tested gas contains a small amount of liquid, the gas flow should be from bottom to top.

When measuring liquid flow rate, the liquid flow direction should be from bottom to top: this will not add additional liquid weight to the probe.

7. The sensor is installed on the side of the horizontal pipeline.

Regardless of the type of fluid being measured, the sensor can be installed on the upper side of the horizontal pipeline, especially for measuring superheated steam, saturated steam, and low-temperature liquids. If conditions permit, it is best to use side installation, so that the temperature of the fluid has less impact on the amplifier.

8. The sensor is inverted in a horizontal pipeline.

This installation method is generally not recommended. This installation method is not suitable for measuring general gases and superheated steam. Can be used to measure saturated steam, suitable for measuring high-temperature liquids or situations that require frequent pipeline cleaning.

9. Installation of sensors on insulated pipelines.

When measuring high-temperature steam, the insulation layer should not exceed one-third of the height of the support.

10. Selection of pressure and temperature measurement points.

According to the measurement requirements, when measuring pressure and temperature near the sensor, the pressure measuring point should be 3-5D downstream of the sensor, and the temperature measuring point should be 6-8D downstream of the sensor.
