How to clean the electromagnetic flow meter

Abstract: The information on how to clean up the electromagnetic flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. If the medium measured by the electromagnetic flowmeter is relatively dirty for a long time, after the electromagnetic flowmeter works for a period of time, scaling will occur on the electrodes. When the conductivity of the fouling substance is different from the conductivity of the measured medium, it will bring measurement error. Sludge, oil. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on how to clean up the electromagnetic flowmeter. If the medium measured by the electromagnetic flowmeter is relatively dirty for a long time, after the electromagnetic flowmeter works for a period of time, scaling will occur on the electrodes. When the conductivity of the fouling substance is different from the conductivity of the measured medium, it will bring measurement error. The adhesion of sludge and oil to the electrodes will also cause the output of the instrument to swing and drift. Therefore, in this case, we need to regularly maintain and clean the electromagnetic flowmeter electrodes. Electromagnetic flowmeter measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity; there are no obstructed flow parts in the measuring tube, no pressure loss, and straight pipe section requirements are low; there are various options for sensor lining and electrode materials; converters Adopt novel excitation method, low power consumption, stable zero point and high accuracy. 1. For inorganic pollution, the electrode can be immersed in 0.1mol/L dilute hydrochloric acid for 30 minutes, washed with pure water, and then immersed in 3.5MOL/L potassium chloride solution for 6 hours before use. 2. Immerse in 4% hydrogen fluoride solution for 3~5s, take out and rinse with distilled water, then soak in 0.1mol/L hydrochloric acid solution for several hours, rinse with distilled water, and calibrate. 3. The surface of platinum is seriously polluted and an oxide film is formed. The platinum or gold surface can be polished with toothpaste, then washed with pure water, and then immersed in 3.5MOL/L potassium chloride solution for 6 hours before use. 4. For organic oil pollution and oil film pollution, the platinum or gold surface can be cleaned with detergent, then washed with pure water, and then immersed in 3.5MOL/L potassium chloride solution for 6 hours before use. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'How to clean the electromagnetic flow meter'
