Electromagnetic flowmeter measurements are not affected by changes in fluid density, viscosity, temperature, pressure and conductivity; there are no obstructed flow components in the measurement tube, no pressure loss, and low straight pipe section requirements; sensor linings and electrode materials have multiple options; The use of a novel excitation method, low power consumption, zero stability, and high accuracy.
1. For inorganic contamination, the electrode may be immersed in 0.1 mol/L dilute hydrochloric acid for 30 minutes, rinsed with pure water, and immersed in 3.5 MOL/L potassium chloride solution for 6 hours before use.
2, 4% hydrogen fluoride solution immersion 3 ~ 5s, remove with distilled water, then soaked in 0.1mol/L hydrochloric acid solution for several hours, rinse with distilled water, calibration.
3. The surface of platinum is heavily polluted by an oxide film. The surface of platinum or gold 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 and oil film contamination, the surface of platinum or gold can be washed with detergent and washed with pure water, and then immersed in 3.5MOL/L potassium chloride solution for 6 hours.
Electromagnetic Flowmeter If the measured medium is relatively dirty for a long time, then after the electromagnetic flowmeter has worked for a period of time, fouling may occur on the electrode. When the conductivity of the fouling material is different from the conductivity of the measured medium, measurement errors will occur. The attachment of sludge and oil to the electrode will also cause the meter output to swing and drift. Therefore, in this case we need to regularly maintain and clean the electromagnetic flowmeter electrodes.
