If the electromagnetic flow meter is maintained in the shutdown state

Abstract: If you maintain the electromagnetic flowmeter meter information in the shutdown state, the excellent flowmeter and flowmeter production and quotation manufacturers will provide you with it. If the electromagnetic flowmeter is maintained in the shutdown state, the electromagnetic flowmeter should also be maintained when it is not in use, because the instrument will fail if it is not used for a long time. We know that instruments and meters have a service life, and the instruments have been used. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on how to maintain the electromagnetic flowmeter in the shutdown state. If the electromagnetic flowmeter is maintained in the shutdown state, the electromagnetic flowmeter should also be maintained when it is not in use, because the instrument will fail if it is not used for a long time. We know that instruments and meters have a service life, and instruments will wear during use. Reasonable maintenance can not only prolong the service life of instruments and meters, but also improve the accuracy of measurement, which has far-reaching significance for instruments and meters. The following are produced by Guangzhou flowmeter manufacturers——Dichuan Instrument will briefly introduce the maintenance measures of the electromagnetic flowmeter in the shutdown state. 1. Zero point inspection and adjustment Before the electromagnetic flowmeter is put into operation, the zero point must be adjusted when the electromagnetic flowmeter is full of liquid and static after power-on. After being put into operation, it is also necessary to periodically stop the flow for zero-point inspection according to the conditions of use; especially for precipitation, easily polluted electrodes, and non-cleaning liquids containing solid phase, more inspections should be carried out in the early stage of operation to gain experience to determine the normal inspection cycle. Compared with the rectangular wave, the electromagnetic flowmeter of the AC excitation method is more prone to zero drift, so more attention should be paid to inspection and adjustment. 2. Regularly check the electrical performance of the sensor First, roughly measure the resistance between the electrodes of the electromagnetic flowmeter. Disconnect the signal connection between the sensor and the converter, fill the sensor with liquid, measure the resistance between the two electrodes and the ground terminal with a multimeter, whether it is within the range specified by the manufacturer, and the two measured values ​​are roughly the same. Record the resistance value of the first measurement, which is useful for later determining the cause of the sensor failure (such as whether the deposited layer is conductive or insulating). Next, empty the liquid of the electromagnetic flowmeter sensor, wipe the inner wall, and measure the resistance between the two electrodes and the ground terminal with a megohmmeter after it is completely dry. Finally, check the insulation resistance of the excitation coil, remove the sensor excitation coil, wire the terminal to the converter, and measure the insulation resistance of the coil with a megohmmeter. Have you got these maintenance methods? Don't think that the flowmeter does not pay attention to maintenance if it is not in use, this will only speed up the damage to the flowmeter.
