Installation skills of vortex flowmeter

Abstract: The information on installation skills of vortex flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Vortex flowmeters are sensitive flowmeters to pipeline flow velocity distribution distortion, swirling flow, and flow pulsation. Therefore, full attention should be paid to the installation conditions of on-site pipelines, and the instructions for use should be strictly followed. Vortex flowmeters can be installed indoors or outdoors. If Ann. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the installation skills of the vortex flowmeter. Vortex flowmeters are sensitive flowmeters to pipeline flow velocity distribution distortion, swirling flow, and flow pulsation. Therefore, full attention should be paid to the installation conditions of on-site pipelines, and the instructions for use should be strictly followed. Vortex flowmeters can be installed indoors or outdoors. If it is installed in the ground well, in order to prevent being submerged by water, the saliva type sensor should be selected. The sensor can be installed horizontally, vertically or obliquely on the pipeline, but when measuring liquids and gases, in order to prevent the interference of air bubbles and droplets, the installation position should be paid attention to. The vortex flowmeter must ensure that the upstream and downstream straight pipe sections have the necessary length. When connecting with pipes, pay attention to the following issues. ①Inner diameter D of upstream and downstream piping and inner diameter D of sensor′The same, the difference satisfies the following conditions: 0.95D≤D′≤1.1D. ② The piping should be concentric with the sensor, and the coaxiality should be less than 0.05D′. ③The gasket cannot protrude into the pipeline, and its inner diameter can be 1~2mm larger than the inner diameter of the sensor. ④If it is necessary to cut off the flow to check or clean the sensor, a bypass pipeline should be set up. ⑤ The impact of reducing vibration on the vortex flowmeter during on-site installation is worthy of attention. Avoid vibration sources as much as possible, use elastic hoses to connect in small diameters, and install pipe supports. Installation skills of vortex flowmeter: 1. The vortex flowmeter can only be measured in one direction. When installing, pay attention to ensure that the direction of the medium flow is consistent with the direction shown by the flowmeter arrow. 2. The vortex flowmeter is installed vertically, and the medium passes through the flowmeter from bottom to top. That is, the flowmeter is installed on the vertical pipe, and the flow direction is from bottom to top. 3. When installing horizontally, the flowmeter must be installed in the high-pressure area of ​​the entire system and ensure the corresponding outlet pressure; do not install it at the high point of the pipeline, because the gas tends to accumulate at the high point, the pipeline is not full, and the outlet cannot be directly vented. 4. When measuring high temperature fluid, try to install it vertically; if it has to be installed horizontally, please install the transmitter part of the flowmeter vertically downwards, or install it horizontally to the side to avoid excessive temperature; pay attention to the air flow at the installation location or well ventilated. 5. Requirements for straight pipe sections: at least 15 times the pipe diameter before the flowmeter and 5 times the pipe diameter after the flowmeter. If there are interference sources such as elbows, indents, and expansions in front of the flowmeter, it is necessary to ensure that 30–40 times the pipe diameter, 6 times the pipe diameter after the flowmeter. The flow meter should be installed upstream of the regulating valve, pressure or temperature sensor. 6. When installing, note that the diameter of the pipe should be slightly larger than or equal to the inner diameter of the instrument. 7. When using the sealing ring, pay attention that the inner diameter of the sealing ring should be slightly larger than or equal to the inner diameter of the instrument, and the center of the sealing ring is located in the center of the pipeline. When the cable inlet is sealed and the instrument is electrically connected, attention must be paid to the sealing of the inlet hole. The corresponding sealing interface (M20Χ1.5; 1/2) must be selected according to the instrument cable entry model.”NPT;G1/2”) and installed correctly and tightly. One of the most common reasons for instrument damage is lack of sealing joints, or sloppy installation, which fails to achieve the sealing effect. The above is the whole content of this article.
