Stop condition under electromagnetic flowmeter scale how to maintenance and maintenance

Abstract: the electromagnetic flow meter scale how to preventive maintenance and downtime state information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Electromagnetic flowmeter in downtime when not in use, we have to respond to the electromagnetic flowmeter is scientific and reasonable maintenance and maintenance method. In technical services to the user for electromagnetic flowmeter, often encounter the user after purchase electromagnetic flowmeter USES period of time,. More flow meter manufacturers choose model price quote you are welcome to inquire, here is how electromagnetic flowmeter scale preventive maintenance and downtime state article details. Electromagnetic flowmeter in downtime when not in use, we have to respond to the electromagnetic flowmeter is scientific and reasonable maintenance and maintenance method. In technical services to the user for electromagnetic flowmeter, often encounter the user after purchase electromagnetic flowmeter USES period of time, again using found inaccurate measurement data. In fact this is not the quality problem of the electromagnetic flowmeter itself exists. Because the user is not according to the directions after use of the maintenance and maintenance methods. First, regular inspection of the electromagnetic flowmeter maintenance sensor performance: first, roughly measure resistance between electrodes. Disconnect between the converter and signal connection of sensor and sensor inside fluid-filled, to the two electrodes and grounding resistance value is measured with a multimeter, e. range is in the factory, and measured by two values the same. Record the measured resistance value for the first time, after this value to judge the sensor failure reason ( If sediment is conducting or insulating) Is useful. Secondly, sensor emptying liquid, wipe the lining, after being completely dry megohm meter was used to measure the resistance between the two electrodes and earthing terminal. Zui, check the excitation winding insulation resistance, sensor excitation coil, terminal and converter indirectly line by megohmmeter measuring insulation resistance of the coil (2) electromagnetic flowmeter zero check and adjustment of maintenance: electromagnetic flowmeter before put into operation, must after the power supply in the electromagnetic flow sensor with fluid under stationary state adjust the zero point. After put into operation or to use condition periodically stop flow for zero check; Especially on precipitation, easy pollution electrode, the cleaning liquid containing solid phase, at the beginning of the run should be checked, in order to obtain experience to determine the normal inspection cycle. Ac excitation mode of electromagnetic flowmeter with rectangular wave excitation, are more likely to produce zero drift, so more attention should be paid to check and adjust. For the application of sediment failure two examples of the error. One is drilling cementing engineering, the total flow perfusion slurry is an important process parameters, often with high-pressure electromagnetic flowmeter. Instrument intermittent use, with finish to wash after sensor tube, the rest of the time are hollow tubes. Due to inadequate cleaning, measuring residue slurry solidifying into a thin layer of tube wall, nearly two months accumulation form the insulating layer, covering the entire electrode surface, leading to run is not normal to zui eventually won't work. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

Given the important role played by in ensuring proper functioning of coriolis density meter, every individual must take an interest towards improving fork density meter manufacturer.
