Vortex flowmeter installation requirements
Core Tip: The best installation method for the vortex flowmeter is vertical installation, and the medium passes through the flowmeter from bottom to top. Install the flowmeter on a vertical pipe with the flow direction from bottom to top.
Let me introduce you below:
1. The vortex flowmeter can only be measured in one direction. When installing, please ensure that the direction of the medium flow is consistent with the direction indicated by the flowmeter arrow.
2. The best installation method of the vortex flowmeter is vertical installation, and the medium passes through the flowmeter from bottom to top. Install the flowmeter 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 zone of the whole system and ensure the corresponding outlet pressure; do not install at the highest point of the pipeline, because the highest point is often gas accumulation, the pipeline is not full, and the outlet cannot be directly emptied.
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 downwards or horizontally to avoid excessive temperature; pay attention to the air flow at the installation position. Or well ventilated.
5, straight pipe section requirements: at least 15 times the pipe diameter before the flow meter, 5 times the pipe diameter after the flow meter. If there are elbows, indents, expansions and other sources of interference in front of the flowmeter, the diameter of the flowmeter should be 30–40 times, and the diameter of the flowmeter should be 6 times. The flow meter should be installed upstream of the regulator valve, pressure or temperature sensor.
6. When installing, please note that the pipe diameter should be slightly larger than or equal to the inner diameter of the instrument.
7. When using the 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. The center of the sealing ring is at the center of the pipe.
8. 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"NPT; G1/2") must be selected according to the meter cable entry model and installed correctly and tightly. There is no sealing joint, or sloppy installation, the sealing effect is not achieved.
