About the use characteristics of electromagnetic flowmeter

strengthen the dynamic management of industry norms

electromagnetic flowmeter has the advantages of high measurement accuracy, strong reliability, good stability, complete functions, long service life and so on. It relies on the development of standardized manufacturing system and advanced design concept to ensure the high accuracy and high reliability of products

the measuring channel of the electromagnetic flowmeter is a smooth straight pipe without flow blocking detection parts, which is suitable for measuring liquid-solid two-phase fluids containing solid particles or fibers, such as pulp, coal water slurry, mineral slurry, slurry and sewage, because it should not be blocked

because the induced voltage signal is formed in the whole space full of magnetic field and is the average value on the pipe load surface, the straight pipe section required by the sensor is relatively short, and the length of 5 times of the pipe direct loading speed indicator is pre selected

the measurement accuracy of electromagnetic flowmeter is not affected by the changes of fluid density, viscosity, temperature, pressure and conductivity. The sensor induced voltage signal has a linear relationship with the average flow rate, so the measurement accuracy is high. It does not produce the pressure loss caused by the detection flow, and the resistance of the instrument is only the resistance along the same length of pipeline. The energy-saving effect is significant, and it is most suitable for large-diameter water supply pipelines requiring low resistance loss

electromagnetic flow may be relatively strange. Only the lining and electrode of the sensor are in contact with the measured liquid. As long as the electrode and lining materials are reasonably selected, they can be corrosion-resistant and wear-resistant

however, the use of electromagnetic flowmeter also has some limitations, such as: it can not measure gas, steam and liquid containing more large bubbles; Liquids with low conductivity, such as petroleum products and organic solvents, cannot be measured. Also, due to the limitations of lining materials and electrical insulation materials, it cannot be used to measure liquids with higher temperatures

electromagnetic flowmeter is widely used in sewage, fluorine chemical industry, production water, tap water industry, medicine, steel and other industries. It is a mature technology Using XT (5) 0 impact sample projector is an optical instrument specially developed by our company according to the actual needs of users and the requirements of impact sample notch in gb/t299 (1) 994 "metallic Charpy impact test method", which is convenient and cost-effective flowmeter for testing the processing quality of Charpy V-notch and u-notch
