Correct installation method of gas vortex flowmeter

Abstract: The information on the correct installation method of the gas vortex flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. The gas vortex flowmeter can be widely used in large, medium and small pipelines to measure the flow of compressed air, saturated and superheated steam, natural gas and various media, and can be used as a flow transmitter in automatic control systems. , stable, use. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the article details of the correct installation method of gas vortex flowmeters. The gas vortex flowmeter can be widely used in large, medium and small pipelines to measure the flow of compressed air, saturated and superheated steam, natural gas and various media, and can be used as a flow transmitter in automatic control systems. , stability, long service life and so on. The main points that should be paid attention to when installing the vortex flowmeter for measuring steam: 1. There must be enough straight pipe sections upstream and downstream. If there are two 90s in the same plane upstream of the sensor mounting point. Elbow, then: upstream straight pipe section≥25D, downstream straight pipe section≥5D. The regulating valve should be installed beyond 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. 2. Reasonably choose the installation site and environment. Avoid strong power equipment, high frequency equipment, strong power switch equipment; avoid the influence of high temperature heat sources and radiation sources, avoid strong vibration places and strong corrosive environments, etc., and consider the convenience of installation and maintenance. 3. The pipeline adopts vibration reduction measures. Try to avoid installing the sensor on the pipeline with strong vibration, especially the lateral vibration. If the installation is unavoidable, vibration reduction measures must be taken, and pipe fastening devices and anti-vibration pads should be installed at the upstream and downstream 2D ​​of the sensor. 4. 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. 5. The installation of the sensor in the vertical pipeline. When measuring gas flow, the sensor can be installed on vertical pipes with unlimited flow direction. If the measured gas contains a small amount of liquid, the gas flow should be from bottom to top. When measuring liquid flow, the flow direction should be from bottom to top: this will not add extra liquid weight to the probe. 6. Installation on horizontal pipes 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 part of the pipeline. When measuring liquid flow, if the measured liquid contains a small amount of gas, the sensor should be installed at the lower part of the pipeline. 7. The sensor is installed upside down in the horizontal pipeline. This installation method is generally not recommended. This installation method is not suitable for measuring general gas and superheated steam. It can be used to measure saturated steam, and it is suitable for measuring high temperature liquid or when the pipeline needs to be cleaned frequently. 8. The sensor is mounted on the side of the horizontal pipe. No matter what kind of fluid to measure, the sensor can be installed on the horizontal pipeline, especially for superheated steam, saturated steam and low temperature liquid. 9. Selection of pressure measuring point and temperature measuring point. According to the measurement needs, when the pressure and temperature need to be measured near the sensor, the pressure measurement point should be 3-5D downstream of the sensor, and the temperature measurement point should be 6-8D downstream of the sensor. 10. The installation of the sensor on the pipeline with the insulation layer. When measuring high temperature steam, the insulation layer should not exceed a maximum of one-third of the height of the bracket. The above is the whole content of this article.
