1. What are the well-known manufacturers of electromagnetic flow meters? If there are imported brands, Siemens, Cologne, Emerson, e+h,ABB, Domestic brands such as Kaipei Shifeng Instrument, Shanghai Kent, and Shanghai Lulanji Weiltai are too numerous. The quality balance and quantity vary greatly, and the price and quality are proportional. 2. How is the quality of the electromagnetic flowmeter of Kaifeng Jingbo Automation Instrument Co., Ltd.? 2. Kaifeng Pixiao Jingbo Automation Instrument Co., Ltd. has good electromagnetic flowmeter quality. Kaifeng Jingbo Automation Instrument Co., Ltd. guarantees the quality of electromagnetic flow meters and has excellent equipment. Kaifeng Jingbo Automation Instrument Co., Ltd. is an enterprise that integrates product research and development, production, and sales. It is engaged in the production and sales of industrial automation instruments. 3. Kaifeng electromagnetic flowmeter empty tube alarm processing method
The processing method of Kaifeng electromagnetic flowmeter empty tube alarm mainly includes the following process: confirm whether the measured fluid is full in the measuring tube. The primary reason for the empty tube alarm is that the fluid in the measuring tube is not full, and it is necessary to check whether there is any leakage, gas accumulation or insufficient fluid flow in the pipeline.
. If the fluid is not fully filled, the process flow or pipeline design needs to be adjusted to ensure that the fluid continues to fill the measuring tube. Short circuit test: Connect the converter signal to terminals SIG1, SIG2, and SIGGDN with wires, and observe whether the "empty tube" prompt is cancelled. If the prompt is cancelled, it indicates th
1, SIG
2, SIGGDN) of the electromagnetic flowmeter is firmly connected to the converter and sensor to avoid poor contact or open circuit. Focus on checking whether the wiring terminals are loose, oxidized, or connected incorrectly. Detection of sensor electrode state conductivity ratio test: When the flow rate is zero, observe that the displayed conductivity ratio should be less than 100%. If the conductivity ratio is abnormal, signal distortion may be caused by electrode contamination or low fluid conductivity. Resistance test: In the presence of current, the resistance of terminals SIG
1, SIG2, and SIGGDN should be less than 50k Ω. If the resistance exceeds the standard, it may be due to electrode aging, corrosion, or insulation damage. DC voltage test: Use a multimeter to measure the DC voltage between DS1 and DS2, which should be less than 1V. If the voltage is too high, it indicates that the electrode is contaminated (such as scaling or deposits) and needs to be cleaned. If electrode contamination is detected during the cleaning of the sensor electrode, the cleaning method should be selected according to the fluid properties: rinse with clean water: suitable for general dirt, use a soft bristled brush or cotton cloth to wipe the surface of the electrode. Chemical cleaning: For stubborn dirt (such
