Electromagnetic flowmeter is a very widely used, highly-accepted intelligent flowmeter. How to solve the problems encountered in the use of electromagnetic flowmeter? First, always observe the sensor power cable and transmission cable (or wire) on the electromagnetic flowmeter for damage and aging, and protect the rubber sheath outside the cable. Second, always observe the sensor power cable and transmission cable (or wire) for damage and aging, and protect the rubber sheath outside the cable. Third, remove debris from the straight section upstream of the sensor. Electromagnetic flowmeter faults and solutions 1) The liquid does not flow and has output: 1. The signal transmission cable is connected to the converter and disconnected; 2. The signal cable is disconnected from the electrode connection; 3. The electrode surface is contaminated or an insulating layer is deposited; 4. The grounding is poor or the circuit is broken. Solution: 1. Connect the cable; 2. Open the sensor and reconnect it; 3. Scrub the electrode surface; 4. Connect the ground wire. 2) No liquid flow output: 1. The signal transmission cable between the converter and the two core wires is reversed; 2. The power supply is not connected or has poor contact; 3. The sensor instrument track, housing, and end face have leakage. Solution: 1. Reverse the head; 2. Connect the power supply and maintain good contact; 3. Repair the sensor. 3) The output is not stable: 1. The flow field is unstable; 2. The gas passing through the sensor contains large solid blocks; 3. The virtual connection of the electrical connection; 4. Bad grounding; 5. Electrode leakage Solution: 1. Rebuild the pipeline, or increase the installation of false sensors; 2. Normal phenomenon; 3. Check the wiring, connect the wires; 4. Connect the ground wire; 5. Repair the sensor. 4) The error is too large: 1. The zero is too high; 2. It is not completely filled with liquid; 3. The power supply has a large distortion; 4. The grounding is poor. Solution: 1. Re-adjust the zero point; 2. Improve the pipeline conditions, the sensor is always full of liquid; 3. Improve the power supply conditions, in line with normal working conditions; 4. Connect the ground wire. Flow meter brand is now many, there are imported and domestic, and now some of the domestic quality of the flow meter can completely replace imported similar products, such as Jiangsu Fenghui instrument electromagnetic flowmeter, the introduction of foreign advanced technology. Buy electromagnetic flowmeter to look for manufacturers, the flowmeter is a flow meter, the need is the product's stability, reliability, accuracy, find a sincere flow meter manufacturers can guarantee the quality of the product. CNC Rapid Prototyping is the first step to test the product feasibility. Prototype(model) is the first sample of production, the designer usually uses this method to get a prototype to observe his new product`s advantages or disadvantages to avoid wasting too much time, money and manpower between the processing of rapid prototyping. Rapid Prototyping can be applied to many fields.
