Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic flowmeters, and more specifically to a novel electromagnetic flowmeter with high precision. Background Art

[0002] Electromagnetic flowmeter is a new type of flow measurement instrument that developed rapidly in the 1950s and 1960s with the development of electronic technology. Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field.

[0003] After searching, the existing patent number is CN211373726U, which is an electromagnetic flowmeter. The electromagnetic flowmeter includes a flowmeter body with a signal input line, a signal output and a power line. The flowmeter body is vertically connected to the measuring conduit through a connecting pipe. Bearings are provided at both ends of the measuring conduit. The inner rings of the two bearings are fixed with connecting threaded pipes. The inner walls of the connecting threaded pipes are tapped with concave threads and a layer of sealing gaskets. The electromagnetic flowmeter can freely rotate the connecting threaded pipe to connect to the measured pipeline while keeping the flowmeter and the measuring conduit stationary. It is easy to operate and easy to disassemble and assemble the electromagnetic flowmeter on the measured pipeline.

[0004] For the above-mentioned electromagnetic flowmeter, after being assembled relative to the pipeline, since there is no supporting component on the outside of the flowmeter, the flowmeter is suspended relative to the supporting surface during use. It is easily loosened due to the impact of water flow, which reduces the measurement accuracy. Therefore, we propose a new type of electromagnetic flowmeter with high precision to solve the above-mentioned problems. Utility Model Content
