Description of the installation method of the liquid flowmeter sensor

The multi-electrode structure of the liquid flow meter sensor ensures the measurement accuracy and does not require a grounding ring in any place, which greatly reduces the troubles caused by the installation and maintenance of the flow meter.
1. The instrument is installed with flange connection, threaded connection and clip-on type;
2. The direction of liquid flow during installation should be consistent with the direction of the arrow indicating the flow direction on the sensor casing, and the upstream straight pipe section should be ≥20dn, and the downstream straight pipe section should be ≥5dn, where dn is the pipe inner diameter.
3. The sensor should be kept away from the external magnetic field. If it cannot be avoided, necessary measures should be taken; in order to prevent the normal transportation of the liquid during maintenance, the bypass pipe should be installed outside the straight pipe section at both ends of the sensor;
4. When the sensor is installed in the open air, please make the waterproof processing of the amplifier plug; the wiring of the sensor and the display instrument should be selected according to the power supply of the amplifier;
5. The liquid flow meter sensor can be installed horizontally and vertically, and the fluid direction must be upward when hanging. The liquid should be filled with tubing and must be free of air bubbles.
6. When installing, the direction of liquid flow should be the same as the direction of the arrow indicating the flow direction on the sensor housing. The upstream end of the sensor shall have at least 20 times the straight pipe length of the nominal diameter, and the downstream end shall be not less than 5 times the straight pipe section of the nominal diameter. The inner wall shall be smooth and clean, free from defects such as dents, scale and skin.
7. If the fluid is unstable and has pulsating flow, a buffer can be installed to ensure good measurement of the rotameter to eliminate pulsating flow.
8. When the rotameter is in use, it should first slowly open the control valve on the upstream pipe of the flowmeter, and then adjust the flow with the regulating valve to avoid the sudden opening of the float causing the float to rise and damage the cone.
The installation method of the liquid flowmeter sensor is like this. Everyone must pay attention to the installation details during the installation process, and install it in combination with other aspects.
