This article is reproduced from: http://www.shllzdh.cn/information/907.html. Keywords of this article: electromagnetic flowmeter. http://www.shllzdh.cn/ Electromagnetic flowmeters are used to measure the volumetric flow rate of conductive liquids in closed pipelines, such as sewage, clean water, and various acid, alkali, and salt solutions. However, sometimes small problems arise when using it, such as a decreasing signal strength or no data output, which can be quite troublesome for us. Below, the editor will introduce some relevant information to you. When using an electromagnetic flowmeter, the signal becomes weaker or drops suddenly; the reason is that dirt may have accumulated on the inner wall of the measurement tube, so the electrodes should be cleaned and wiped ； Check whether the lining of the measurement tube is damaged; if so, it should be replaced ； Do not scratch the lining; test whether the insulation between the two electrodes is short-circuited or damaged. The normal resistance value between the two electrodes should be between (70–100) Ω. No flow output when using the electromagnetic flowmeter; reason: The test fuse is not functioning properly ； Check for any faults in the power supply section and test whether the power voltage is normal ； Check whether the sensor is filled with fluid; if not, install it vertically or replace the pipeline ； Check whether the sensor arrow is in line with the flow direction of the fluid; if not, reverse the installation direction of the sensor. Above, the editor has explained to you what actions should be taken when faults occur during the use of electromagnetic flowmeters. Feel free to leave comments if there is any additional information.
