Content description
The utility model is an electromagnetic flowmeter monitoring system, which belongs to the field of detection equipment.

Background of the invention
In the prior art, the electromagnetic flowmeter is an instrument used to measure the volume flow of conductive liquids based on Faraday's electromagnetic induction theorem, which has been rapidly developed with the development of electronic technology. It has no moving parts, no throttling parts obstructing the flow of the medium, and no additional pressure loss to the flow of the measured fluid, but only the resistance along the pipe section; it measures the flow of the conductive medium without being affected. Its temperature, stiffness, density, pressure and other physical parameters; no mechanical inertia, sensitive reflection, measurable instantaneous pulsating flow; good linearity, high measurement accuracy, wide measurement range, strong corrosion resistance, etc. Therefore, among the many flow meters, the electromagnetic flowmeter has become one of the fast-developing flow meters. However, the existing electromagnetic flowmeter has the problem of delayed data transmission. Therefore, an electromagnetic flowmeter monitoring system is needed to solve the above problems.

Summary of the invention
In view of the shortcomings of the prior art, the purpose of the present utility model is to provide an electromagnetic flowmeter monitoring system to solve the problems raised in the background art mentioned above. The utility model is convenient to use, easy to operate, good in stability and high in reliability.
