LUGB vortex flowmeter measures volumetric flow of gas, steam or liquid, standard volumetric flow or mass flow. Mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media.
1. The intelligent vortex flowmeter can only measure in one direction, and pay attention to ensure that the direction of the medium flow is consistent with the direction of the arrow of the flowmeter during installation.
2. The best installation method for LUGB vortex flowmeter is vertical installation, and the medium passes through the flowmeter from bottom to top. That is, the flowmeter is installed on a vertical pipe with the flow direction from bottom to top.
3. When installing horizontally, the flowmeter must be installed in the high-pressure area of ​​the entire system, and the corresponding outlet pressure must be ensured; do not install it at the highest point of the pipeline, because the highest point tends to accumulate gas, the pipeline is not full, and the outlet cannot be directly Short.
4. When measuring high temperature fluid, try to use vertical installation method; if you have to install horizontally, please install the transmitter part of the flowmeter vertically down or horizontal side to avoid excessive temperature; pay attention to the air flow at the installation location Or well ventilated.
5. Straight pipe section requirements: at least 15 times the pipe diameter before the flowmeter and 5 times the pipe diameter behind the flowmeter. If there are elbows, indentation, expansion and other interference sources in front of the flowmeter, you need to ensure that the pipe diameter is 30-40 times before the flowmeter and 6 times the pipe diameter after the flowmeter. The flowmeter should be installed upstream of the regulating valve, pressure or temperature sensor. 6. When installing, pay attention to the pipe diameter should be slightly greater than or equal to the inner diameter of the instrument. 7. When using the seal ring, pay attention that the inner diameter of the seal ring should be slightly greater than or equal to the inner diameter of the instrument, and the center of the seal ring is located in the center of the pipeline.
Cable inlet seal of intelligent vortex flowmeter
When the instrument is electrically connected, attention must be paid to the sealing of the inlet hole. The corresponding sealed interface (M20Χ1.5; 1/2 "NPT; G1 / 2") must be selected according to the instrument cable entry model, and installed correctly and tightly. Without sealing joints, or installing sloppy, can not achieve the sealing effect, is one of the most common causes of instrument damage.
