Sanitary electromagnetic flowmeter

Overview of Sanitary electromagnetic flowmeter

The sanitary electromagnetic flowmeter adopts a new sanitary lining material and lining process, which meets the sanitary requirements of the food industry. At the same time, it adopts a stainless steel shell and stainless steel clamp connection to facilitate the rapid disassembly and cleaning of the electromagnetic flowmeter, so that the electromagnetic flowmeter is not easy to be polluted in the process of use, and can effectively prevent the accumulation of measuring fluid residues in the measuring pipe. It can be widely used in mineral water, soy sauce, jam, beer The production and manufacturing process of fruit juice, rice wine, milk and other foods, as well as health, chemical and other fields.

Working principle of Sanitary electromagnetic flowmeter
The working principle of electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. In the electromagnetic flowmeter, the conductive medium in the measuring tube is equivalent to the method
For the conductive metal rod in the Ladi test, two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows through, an induced voltage will be generated. Two electrodes inside the pipe measure the induced voltage generated. The measuring pipe is electromagnetically isolated from the fluid and the measuring electrode through a non-conductive lining (rubber, Teflon, etc.).

Main advantages of Sanitary electromagnetic flowmeter
1) The sensor structure of the electromagnetic flowmeter is simple, and there are no movable parts in the measuring tube, nor any throttling parts that hinder the flow of fluid. Therefore, when the fluid passes through the flowmeter, it will not cause any additional pressure loss. It is one of the flow meters with the lowest energy consumption in operation.
2) It can measure the flow of dirty medium, corrosive medium and suspended liquid-solid two-phase flow. This is because there are no obstructing flow parts inside the measuring tube of the instrument, and only the inner lining and electrode of the measuring tube are in contact with the measured fluid, and the material can be selected according to the nature of the measured fluid. For example, with polytetrafluoroethylene or polytetrafluoroethylene as the lining, various corrosive media such as acid, alkali and salt can be measured; With wear-resistant rubber as the lining, it is particularly suitable for measuring the liquid-solid two-phase flow of ore pulp, cement slurry and other liquids with solid particles and large wear, as well as various suspended liquids with fibers and pulp.
3) Electromagnetic flowmeter is a volume flow measurement instrument. In the measurement process, it is not affected by the temperature, viscosity, density and conductivity (within a certain range) of the measured medium. Therefore, the electromagnetic flowmeter can be used to measure the flow of other conductive liquids only after being calibrated by water.
4) The output of the electromagnetic flowmeter is only proportional to the average velocity of the measured medium, and has nothing to do with the flow state (laminar flow or turbulence) under symmetrical distribution. Therefore, the measuring range of electromagnetic flowmeter is extremely wide, and its measuring range can reach 100:1, and some even reach the operable flow range of 1000:1.
5) The electromagnetic flowmeter has no mechanical inertia and is sensitive. It can measure the instantaneous pulsating flow and the flow in both positive and negative directions.
6) The caliber range of industrial electromagnetic flowmeter is extremely wide, from a few millimeters to a few meters, and there are real flow calibration equipment with a caliber of 3m in China, which has laid a foundation for the application and development of electromagnetic flowmeter.
