The good price and quality electromagnetic water flow meter china is mainly used to measure the volume flow of conductive liquid and slurry in closed pipelines. Including acid, alkali, salt and other highly corrosive liquids. The product is widely used in petroleum, chemical industry, metallurgy, textile, food, pharmaceutical, paper and other industries, as well as environmental protection, municipal management, water conservancy construction and other fields.
Fault of good price and quality electromagnetic water flow meter china I. Analysis of output causes of liquid not flowing: 1. There is an open circuit in the signal transmission cable connection with the converter; 2. Open circuit of signal cable to electrode connection; 3. Contamination or deposition of insulating layer on electrode surface; 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.
Fault of good price and quality electromagnetic water flow meter china II. Cause analysis of no output of liquid flow: 1. The two core wires of the signal transmission cable with the converter are connected reversely; 2. The power supply is not connected or has poor contact; 3. There is leakage in the pipeline, shell and end face of the sensor instrument.
Solution: 1. Thread reversing; 2. Connect the power supply and keep good contact; 3. Repair the sensor.
Fault of good price and quality electromagnetic water flow meter china III. cause analysis of excessive error: 1. The zero point is too high; 2. Not fully filled with liquid; 3. Excessive distortion of power supply; 4. Poor grounding.
Solution: 1. Readjust the zero point; 2. Improve the channel conditions, and the sensor is always full of liquid; 3. Improve the power supply conditions to meet the normal working conditions; 4. Connect the ground wire.
Fault of good price and quality electromagnetic water flow meter china IV. cause analysis of unstable output: 1. Unstable flow field; 2. The liquid passing through the sensor contains gas and large solid blocks; 3. Virtual connection of electrical connection; 4. Poor grounding; 5. Electrode leakage.
Solutions: 1. Transform the channel or install false sensors; 2. Check and connect the wiring; 3. Connect the ground wire; 4. Repair the sensor.
