Description
technical field [0001] The electrode device of an electromagnetic flow sensor according to the invention relates to the field of electromagnetic flow sensors with low power consumption. The invention is applicable to household heat meters, cold meters, water meters, etc. with built-in valves, and its principle and structure are also applicable to other general fields requiring flow measurement and control. Background technique [0002] Electromagnetic flowmeter is a flow measuring instrument based on Faraday's electromagnetic induction principle. Its basic principle is: when a fluid with a conductive medium passes through a magnetic field, the fluid cuts the lines of magnetic force and generates an induced potential in the vertical direction of the magnetic field. The magnitude of the induced potential is It is proportional to the flow velocity of the fluid, so as to obtain the flow velocity of the fluid, and then obtain the flow rate of the fluid. In order to generate a ma...
