Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic flowmeters, in particular to an electromagnetic flowmeter with a shell protection function. Background Art

[0002] Electromagnetic flowmeter is a sensor used to measure the flow and density of conductive fluids. It works based on Faraday's law of electromagnetic induction. Unlike traditional differential pressure flowmeters, electromagnetic flowmeters do not need to directly contact the fluid, so they can achieve advantages such as zero leakage, high precision, and anti-interference. Electromagnetic flowmeters are widely used in flow measurement, sewage treatment, energy metering, and other fields in industrial production processes.

[0003] When the electromagnetic flowmeter is in use, a casing needs to be installed to protect it. When the existing flowmeter casing is in use, ventilation holes are usually reserved to ventilate the flowmeter for heat dissipation. However, after long-term use, dust will enter the casing through the ventilation holes, causing a large amount of dust to adhere to the surface of the flowmeter. The dust not only affects the measurement accuracy of the flowmeter, but also affects the user's observation of the measuring instrument panel. In addition, the casing has a poor protective effect on the flowmeter. A collision with the casing will cause the flowmeter to vibrate, causing damage to the internal components of the flowmeter.

[0004] Therefore, it is necessary to provide a new electromagnetic flowmeter with shell protection function to solve the above technical problems. Utility Model Content
