Technical Field

[0001] The utility model relates to the technical field of electromagnetic flowmeters, in particular to a micro-sized electromagnetic flowmeter. Background Art

[0002] Electromagnetic flowmeters are made using Faraday's law of electromagnetic induction and can accurately detect the flow of conductive fluids. However, due to the measurement principle, the flowmeter is very large, and due to the principle requirements, current excitation is required to generate a strong magnetic field, requiring space to be reserved for the installation of the instrument on site, and there is a requirement for a straight pipe section of 5 in front and 3 in the back, which requires a higher space for the installation of the instrument. However, in some usage scenarios, especially when applied to some equipment, the installation space requirements for the instrument are very strict, and there is not enough space for installation.

[0011] By installing various components together inside the electromagnetic flowmeter, leaving only a conduit outside to connect to the aviation plug inside it, and connecting the front pipe joint with the rear pipe joint and the pipeline, the electromagnetic flowmeter can occupy a smaller volume, be lighter, and have a more compact structure. It can adapt to various pipe sizes and can be installed and used in a limited space.

[0012] Since the electromagnetic flowmeter is small in size and light in weight, it is convenient to carry and move, and is suitable for occasions where the installation location needs to be changed frequently. Due to its small size, the electromagnetic flowmeter usually has lower energy consumption, which helps to save energy costs. Due to its small size, the electromagnetic flowmeter is relatively simple to maintain and is easier to clean and maintain. BRIEF DESCRIPTION OF THE DRAWINGS
