Analysis on the maintenance method of sewage flow meter when it stops running

Abstract: Analysis of the maintenance method information when the sewage flow meter is out of operation is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. Analysis of the maintenance method of sewage flowmeter when it stops running: When the sewage flowmeter is not in use, we must adopt scientific and reasonable protection and maintenance methods for the flowmeter. After the user purchases the sewage flow meter, there will be a measurement for a while. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the article on the maintenance methods of sewage flowmeters when they stop running. Analysis of maintenance methods when the sewage flowmeter stops running: When the sewage flowmeter is not in use, we must adopt scientific and reasonable protection and maintenance methods for the flowmeter. After the user purchases the sewage flowmeter, the measurement data will be inaccurate for a while. What is the factor? In fact, it is not the quality problem of the electromagnetic flowmeter, but that you have not maintained it according to the methods in the manual. 1. Check and adjust the zero point of sewage flowmeter protection Before the sewage flowmeter is put into operation, the zero point must be adjusted when the sewage flowmeter is filled with liquid after power-on. After being put into operation, it is also necessary to check the zero point of the operating conditions at regular intervals; especially for accumulation, easily contaminated electrodes, and non-cleaning liquids rich in solid phase, more inspections should be made in the early stage of operation to obtain experience and determine the normal inspection period. The electromagnetic flowmeter that communicates the excitation method is more prone to zero drift than the rectangular wave shock, so pay more attention to checking and adjusting. How to protect the sewage flowmeter from shutdown? Give two examples of application errors in which the accumulation layer fails. One is that in oil drilling and cementing engineering, the total flow of cement slurry is the main technical parameter, and high-pressure electromagnetic flowmeters are often used. The meter is used intermittently. After use, rinse the sensor measuring tube with clean water, and the remaining time is empty. Due to the incomplete cleaning, the residual cement slurry on the inner wall of the measuring tube solidified into a thin layer, which accumulated in the past two months to form an insulating layer, covering all the electrode surfaces, resulting in abnormal operation and eventually unable to work. The other is the electrolytic cutting technology test equipment. The electromagnetic flowmeter is used to control the flow of saturated brine. After a period of intermittent use, it is found that the flow signal is gradually weakened, and the signal is zero after 2 months. The factor is the accumulation of iron oxide on the tube wall during the electrolytic cutting process, which constitutes a short circuit. Removal of the stratification immediately returned to normal. 2. Timely check the electrical function of the sewage flowmeter. How to protect the sewage flowmeter when it shuts down? First, roughly measure the resistance between the electrodes. Disconnect the signal connection between the sensor and the converter, fill the sensor with liquid, and use a multimeter to measure the resistance between the two electrodes and the grounding terminal, whether it is within the range specified by the manufacturer, and the two measured values ​​are roughly the same. Record the resistance value measured for the first time, this value is useful for judging sensor fault factors (such as whether the buildup layer is conductive or insulating) in the future. Next, empty the sensor of the liquid, wipe the inner wall, and use a megohmmeter to measure the resistance between the two electrodes and the ground terminal after it is completely dry. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
