Correct installation of vortex flowmeter

1 Vortex flowmeter can only measure in one direction. During installation, 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 of vortex flowmeter is vertical installation, and the medium passes through the flowmeter from bottom to top. That is, install the flowmeter to decelerate the rotation number of the motor to the desired rotation number on the vertical pipe, and the flow direction is from bottom to bottom. 3. Select three elements of aluminum alloy cable: complete set, quality and cost performance. 3. When the horizontal installation hopes to help the majority of users, the flowmeter must be installed in the high-pressure area of the whole system and ensure the corresponding outlet pressure; Do not install it at the highest point of the pipeline, because the highest point often accumulates gas, and the outlet cannot be directly vented if the pipeline is not full. 4. When measuring high-temperature fluid, try to use the vertical installation method; If it has to be installed horizontally, please install the transmitter part of the flowmeter vertically downward or horizontally on the side to avoid excessive temperature; Pay attention to good air flow or ventilation at the installation position. Rotor pump 5 Requirements for straight pipe section: at least 15 times the pipe diameter of the flowmeter and 5 times the pipe diameter of the flowmeter. If there are elbows, indentations, expansions and other interference sources in front of the flowmeter, it is necessary to ensure that the first 30-40 times the pipe diameter of the flowmeter and the last 6 times the pipe diameter of the flowmeter. The flowmeter shall be installed upstream of the regulating valve, pressure or temperature sensor. 6. During installation, pay attention to that the pipe diameter should be slightly greater 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 greater than or equal to the inner diameter of the instrument, and the center of the sealing ring is located in the center of the pipe

cable inlet sealing

when the instrument electricity is connected from the inlet to its own production gas, attention must be paid to the sealing of the inlet hole. The corresponding sealing interface (M20) must be selected according to the model of instrument cable inlet Χ 1.5; 1/2”NPT; G1/2 "), and install correctly and tightly. One of the most common reasons for instrument damage is that there is no sealing joint, or the installation is careless, and the sealing effect cannot be achieved
