Matters needing attention in the installation process of vortex flowmeter

Abstract: The information on matters needing attention in the installation process of the vortex flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. Vortex flowmeter is a new type of flowmeter for fluid flow measurement in closed pipelines based on the Karman vortex principle. Because of its good medium adaptability, it can directly measure the working volume flow of steam, air, gas, water and liquid without temperature and pressure compensation. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of the precautions during the installation of the vortex flowmeter. Vortex flowmeter is a new type of flowmeter that measures fluid flow in closed pipelines based on the Karman vortex principle. Because of its good medium adaptability, it can directly measure the volume flow of steam, air, gas, water and liquid under working conditions without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure the volume flow and mass flow under standard conditions. An ideal alternative to the type flowmeter. However, many users may easily cause errors and some problems during the use of the flowmeter due to some improper operations during the installation process. This article is to provide some installation precautions for the installation process, hoping to enable the majority of users to make better use of the vortex Street Meter. 1. The vortex flowmeter 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. 2. Reasonable selection of installation site and environment for vortex flowmeter. 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. Installation of vortex flowmeter sensors on insulated pipes. When measuring high temperature steam, the insulation layer should not exceed a maximum of one-third of the height of the bracket. 4. There must be enough straight pipe sections upstream and downstream of the vortex flowmeter. 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. If there are two 90s on different planes upstream of the sensor mounting point. Elbow, then: upstream straight pipe section≥40D, 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. 5. The piping upstream and downstream of the installation point of the vortex flowmeter should be concentric with the sensor, and the coaxial deviation should not be less than 0.5DN. 6. The installation of the vortex flowmeter on the horizontal pipeline is the most commonly used installation method of the flow sensor. 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 vortex flowmeter sensor is installed on the side of the horizontal pipeline. 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. 8. Installation of vortex flowmeter sensor in 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. 9. The reverse installation of the vortex flowmeter sensor 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. 10. Selection of pressure measuring point and temperature measuring point of vortex flowmeter. According to the measurement needs, when the pressure and temperature need to be measured near the sensor, the pressure measurement point should be at 3-5D downstream of the sensor, and the temperature measurement point should be at 6-8D downstream of the sensor.
