Split electromagnetic flowmeter easy failure and solutions

The split electromagnetic flowmeter is mainly used to measure the volume flow in conductive liquids and slurries in closed pipelines. Including highly corrosive liquids such as acids, alkalis, and salts. This product is widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal management, water conservancy construction and other fields. Split electromagnetic flowmeter fault 1. Analysis of the reasons for the output when the liquid does not flow: 1. The signal transmission cable between the converter and the converter is disconnected; 2. The connection between the signal cable and the electrode is disconnected; 3. The surface of the electrode is contaminated or the insulation layer is deposited; 4. Poor grounding or open circuit. Solution: 1. Connect the cable; 2. Open the sensor and reconnect it; 3. Scrub the electrode surface; 4. Connect the bottom line. Split electromagnetic flowmeter failure 2. Reason analysis for no output in liquid flow: 1. The two core wires of the signal transmission cable between the converter and the converter are reversely connected; 2. The power supply is not connected or the contact is poor; 3. The sensor instrument pipe, shell, and end face There is a leak. Solution: 1. Replace the thread; 2. Connect the power supply and maintain good contact; 3. Repair the sensor.

Split electromagnetic flowmeter failure 3. Reason analysis for excessive error: 1. The zero point is too high; 2. It is not fully filled with liquid; 3. The distortion of the power supply is too large; 4. Poor grounding. Solution: 1. Re-adjust the zero point; 2. Improve the channel conditions so that the sensor is always filled with liquid; 3. Improve the power supply conditions to meet normal working conditions; 4. Connect the ground wire. Split electromagnetic flowmeter failure 4. Analysis of causes of unstable output: 1. Unstable flow field; 2. The liquid passing through the sensor contains gas and large solid blocks; 3. Virtual electrical connection; 4. Poor grounding; 5. Electrode leakage. Solution: 1. Modify the channel or add fake sensors; 2. Check the wiring and connect the wires; 3. Connect the ground wire; 4. Repair the sensor.
