Abstract: how to stop work under electromagnetic flowmeter scale hairdressing maintains information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. We have to respond to the electromagnetic flowmeter is scientific and reasonable maintenance and maintenance method, downtime is when not in use, a lot of people found in the purchase of electromagnetic flow meter to use after a period of time, again using found inaccurate measurement data. In fact this is not the electromagnetic flow. More flow meter manufacturers choose model price quote you are welcome to inquire, here is stop work under electromagnetic flowmeter scale how hairdressing maintains article details. We have to respond to the electromagnetic flowmeter is scientific and reasonable maintenance and maintenance method, downtime is when not in use, a lot of people found in the purchase of electromagnetic flow meter to use after a 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 does not operate according to the instruction methods in maintenance and maintenance. First, zero check and adjustment of the electromagnetic flowmeter maintenance electromagnetic flowmeter in operation before, after electrify must 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. Two sedimentary malfunction application example 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. Another is electrolytic cutting process on the test rig, saturated salt water flow is controlled by electromagnetic flowmeter, clearance after using a period found that traffic signal gradually weakened, 2 months after the signal is zero. Reason is electrolytic iron deposition in the process of cutting tube wall, formation caused by short circuit. Clear stratification is back to normal immediately. Second, the regular inspection of 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. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
