The electromagnetic flowmeter is a meter for measuring the volume flow of the conductive liquid made according to the Faraday's law of electromagnetic induction. The entire set consists of two parts: the sensor and the converter. Electromagnetic flowmeters have become the first choice for flow metering instruments in the water supply and drainage industry, especially for large diameter electromagnetic flowmeters. Electromagnetic flowmeter selection mainly considers the following factors: medium environment, flow rate, pipe diameter, installation site, environmental conditions, accuracy, etc., and on the basis of analysis and comparison, select the appropriate instrument. The accuracy and effectiveness of electromagnetic flowmeters depends largely on the sensor installation. How to choose the sensor installation environment: 1) The sensor measuring tube must be filled with fluid in use; 2) There should be no strong vibration in the pipe or ground on which the sensor is installed; 3) Avoid large electric motors, large transformers, etc. nearby to avoid electromagnetic interference; 4) Do not use electrical power supplies (such as variable-frequency power supplies, silicon controlled rectifiers, etc.) that will generate high-order harmonics; 5) Avoid installation in places with corrosive gases or dipping or burying in corrosive liquids or soils; 6) The place where the sensor is grounded alone; 7) Select the appropriate location for installation to avoid air bubbles in the measuring tube; 8) The valve for adjusting the flow rate should be installed downstream of the sensor. The electromagnetic flowmeter is installed on the bidirectional flow pipe. Before use, the flow direction should be measured first, and the flow direction set inside the instrument should be consistent with the actual flow direction measured, especially for the determination of flow direction during trade settlement.

High chromium section and low chromium section are widely used in the powder preparation and ultra-fine deep processing of cement building materials, metal mines, coal slurry thermal power, chemical engineering, ceramic coating, light industry paper making, magnetic materials and other industries.High chromium section compared with low grid section has low abrasion, good toughness and less crushing. In the process of use, the surface hardness will be further improved and the wear resistance will be enhanced. At the same time, the production capacity of the grinding machine can be improved, and the specific surface area of cement and the recovery rate of concentrate can be improved.With the rapid development of the national economy, the resource industries such as cement, metallurgy and mining are developing vigorously, and the steel segment application manufacturers are increasing day by day.The invention of high chromium section not only improves the grinding efficiency, reduces the time of stopping for ball filling and The Times of starting and stopping, but also extends the period of stock cleaning and reduces the labor intensity of workers.Especially in the cement mill second three cang and metallurgical concentrator second three section grinding ore use effect is more significant.
