Method of installing vortex flow meter correctly
2024-05-23
Vortex flow meter is a kind of measuring instrument for gas, liquid and steam. The correct installation of vortex flowmeter can better play its use efficiency.
1. Select a proper installation site and environment.
Avoid strong power equipment, high frequency equipment, strong power switchgear; Avoid the influence of high temperature heat sources and radiation sources, avoid strong vibration places and strong corrosion environments, etc., and consider convenient 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, 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, the upstream straight pipe section is ≥40D, and the downstream straight pipe section is ≥5D.
The regulating valve should be installed in the downstream 5D of the sensor, if it must be installed in the 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 upstream and downstream pipes of the installation point should be concentric with the sensor, and the coaxial deviation should not be less than 0.5DN.
4. Take vibration reduction measures for pipelines.
Try to avoid installing the sensor on the pipeline with strong vibration, especially transverse vibration. If it is necessary to install the sensor, vibration reduction measures must be taken, and pipe fastening devices are installed at upstream and downstream 2D of the sensor, and anti-vibration pads are added.
5. Installation on the horizontal pipe is the most common installation method for flow sensors.
When measuring gas flow, if the measured gas contains a small amount of liquid, the sensor should be installed at a higher level of the pipeline.
When measuring liquid flow, if the measured liquid contains a small amount of gas, the sensor should be installed in the lower part of the pipeline.
6. Installation of sensors in vertical pipelines.
When measuring gas flow, the sensor can be installed on the vertical pipe, and the flow direction is unlimited. If the measured gas contains a small amount of liquid, the gas flow should be from the bottom up.
When measuring liquid flow, the liquid flow direction should be bottom-up: this does not attach additional liquid weight to the probe.
