As an instrument for measuring the volumetric flow rate of conductive media in pipes, electromagnetic flowmeters are widely used in many industrial sectors in our country. However, inadequate routine maintenance of these devices leads to various minor faults during operation, which in turn affects their proper functioning. Today, we have invited professionals specializing in electromagnetic flowmeters to explain to us how to maintain them on a daily basis as well as how to diagnose and repair related faults. In the daily use of electromagnetic flowmeters, a visual inspection of the entire instrument is necessary; areas prone to dust accumulation should be cleaned regularly. It is also important to ensure that no water or other contaminants enter the instrument. Electrodes that are prone to contamination and scaling must be cleaned promptly. In many fields where electromagnetic flowmeters are used, the most common issue is related to the maintenance of the electrodes of these flowmeters. Experts recommend that before using an electromagnetic flowmeter, its electrodes should be thoroughly cleaned with distilled water, and then cleaned again using the liquid being measured. When the electromagnetic flowmeter is not in use, its electrodes must be removed. It is crucial to be careful not to let the contacts on the electrodes come into contact with any hard objects while removing them; such contact can easily cause damage to the electrodes. After using the electromagnetic flowmeter, in order to maintain the wetness of the electrode bulbs, a small amount of saturated solution should be poured in before putting on the electrode covers; however, it is important to remember not to soak them in distilled water. For the daily maintenance of electrodes, it is also important to keep them clean and to prevent a short circuit between the outputs on either side of the electromagnetic flowmeter’s electrodes; a short circuit would result in inaccurate measurement results. In the use of electromagnetic flowmeters, some minor faults may occur, and these can all be dealt with easily. For example, if there is no flow output during the use of an electromagnetic flowmeter, the first thing to do is to check the power supply of the flowmeter – such as whether the power supply is functioning properly and whether the fuses are working correctly – or to check whether the sensors inside the flowmeter are in good condition. If there is a sudden drop in the signal or a gradual weakening of it during the use of an electromagnetic flowmeter, the first thing to check is whether the insulation between the electrodes is functioning properly. If the insulation is fine, then the dirt inside the measurement tube needs to be cleaned. For more information, please visit the company’s official website at http://www.yb1518.com/.
