Cleaning and Maintenance of Primary Device of Electromagnetic Flow Meter

Abstract: The cleaning and maintenance information of the primary device of the electromagnetic flowmeter is provided by the excellent manufacturers of flowmeters and flowmeters. This effect can be minimized by using bullet-shaped electrodes with reduced coating, ultrasonic cleaning methods, and capacitive signal detectors. Mechanical, electrical or chemical methods can be used if the insulating substances in the conductive liquid are likely to deposit on the electrodes or on the wall of the measuring tube. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the cleaning and maintenance of the primary device of the electromagnetic flowmeter. This effect can be minimized by using bullet-shaped electrodes with reduced coating, ultrasonic cleaning methods, and capacitive signal detectors. If the insulating material in the conductive liquid is likely to be deposited on the electrode or the wall of the measuring tube, mechanical, electrical or chemical cleaning measures can be taken to clean it. The flowmeter can be cleaned and maintained under the working conditions of connecting with the process pipeline. It can also be removed from the pipe for cleaning. The commonly used cleaning methods are as follows: 1. Mechanical scraper In this system, each electrode is equipped with a rotary scraper, and the blade of the scraper is perpendicular to the surface of the electrode. The shaft of the scraper is driven by an external motor or manually through a hydraulic seal. Can run continuously or intermittently. The shaft of the scraper is driven by an external motor or manually through a hydraulic seal. Can run continuously or intermittently. This method is generally less used in modern electromagnetic flowmeters. 2. Detachable electrode Detachable electrode adopts mechanical valve and sealing device, so the electrode can be disassembled (usually under pipeline working pressure) for external inspection and cleaning. 3. Electrolysis or“burn off”The method of this method is to connect the voltage of the power supply between the two electrodes (the secondary device is automatically disconnected during this operation), resulting in electrolysis on the surface of the two electrodes, and the gas is rapidly released, resulting in the removal of the precipitate. This method is generally used for oily, oily, and sludge-type coverings. Heating of the electrodes can also be used to remove fat and oil deposits from sewage. 4. External oscillators and sensors for ultrasonic cleaning induce high-energy ultrasonic waves on each electrode shaft. By selecting the length of the motor shaft and the frequency of the ultrasonic waves, antinodes are generated on the electrode surface, thereby forming local cavitation on the electrode to remove deposits. This method is generally used for cleaning of crystalline capping layers. The development of the instrumentation industry and technological breakthroughs in the instrumentation industry are inseparable from the support and efforts of various instrumentation manufacturers. As a flow meter manufacturer, we strive to learn new technologies from others, introduce advanced equipment, and develop more technologies to meet the needs of more customers. Chengfeng flowmeter has also gradually sold its products abroad, which is widely loved by customers. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Cleaning and Maintenance of Primary Device of Electromagnetic Flow Meter'
