The invention provides a large-diameter electromagnetic flowmeter comprising a guide pipe. Each end of the guide pipe is provided with a flange. A plastic lining is arranged in the guide pipe. The inner wall of the guide pipe is further provided with a coil and an electrode connected to an electrode lead. The coil and the electrode lead are located between the guide pipe and the plastic lining. The plastic lining is made with a rotational moulding machine. The coil of the large-diameter electromagnetic flowmeter is disposed on the inner wall of the guide pipe, and the plastic lining is made with the rotational moulding machine; accordingly, precision level of the large-diameter electromagnetic flowmeter is increased, the process steps of the large-diameter electromagnetic flowmeter are simplified, and both the precision and reliability of the large-diameter electromagnetic flowmeter are better than those of the existing product.
Description
technical field [0001] The invention relates to a large-diameter electromagnetic flowmeter. Background technique [0002] The large-diameter electromagnetic flowmeter is designed according to the principle of Faraday's law of electromagnetic induction. In the design process, it is based on the principle of making the magnetic field run through the fluid section regularly and uniformly. The non-magnetic material is used to make the conduit. At present, the magnetic permeability is relatively low. Stainless steel materials are commonly used in this occasion. Driven by today's technical conditions and economic cost and other factors, the conduits of small and medium-caliber electromagnetic flowmeters are made of stainless steel seamless steel pipes with low magnetic permeability; the conduits of some medium-sized and even large-caliber electromagnetic flowmeters are made of The stainless steel plate with low magnetic permeability is rolled and formed by a plate rolling machine...
