Installation of vortex flowmeter

Thread Content

1. The vortex flowmeter can only measure in one direction. When installing, pay attention to ensure that the medium flow direction is consistent with the direction indicated by the arrow of the flowmeter. 2. The best installation method for the vortex flowmeter is vertical installation, with the medium passing through the flowmeter from bottom to top. That is, the flow meter is installed on a vertical pipe, and the flow direction is from bottom to top. 3. When installing horizontally, the flow meter must be installed in the high-pressure area of ​​the entire system and the corresponding outlet pressure must be guaranteed ； Do not install it at the highest point of the pipeline, because gas often accumulates at the highest point, the pipeline is not full, and the outlet cannot be vented directly. 4. When measuring high-temperature fluids, try to use vertical installation. ； If you have to install it horizontally, please place the transmitter part of the flow meter vertically downward or install it horizontally on its side to avoid excessive temperature. ； Pay attention to the installation location with good air flow or ventilation. 5. Requirements for straight pipe sections: Ensure at least 15 times the pipe diameter in front of the flow meter and 5 times the pipe diameter behind the flow meter. If there are interference sources such as elbows, indentations, and expansions in front of the flow meter, it is necessary to ensure that the pipe diameter is 30-40 times in front of the flow meter and 6 times the pipe diameter behind the flow meter. 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 a sealing ring, note 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 should be located in the center of the pipe. Cable entry sealing When electrically connecting instruments, attention must be paid to the sealing of the cable entry holes. The corresponding sealing interface (M20Χ1.5; 1/2”NPT; G1/2”) must be selected according to the instrument cable entry model and installed correctly and tightly. There is no sealing joint, or the installation is sloppy and the sealing effect cannot be achieved, which is one of the most common reasons for instrument damage.
