The top of the electromagnetic metering box is covered by an upper cover 4. The electromagnetic metering device 2 specifically includes a set of upper silicon steel sheets 21 and a set of lower silicon steel sheets 22. A set of upper silicon steel sheets 21 is integrally fixed by an upper buckle 23, and a set of lower silicon steel sheets 22 is integrally fixed by a lower buckle 24. A coil sheet 25 is sandwiched between a set of upper silicon steel sheets 21 and a set of lower silicon steel sheets 22. A set of pin assemblies 26 is horizontally inserted into the pipe section between the upper silicon steel sheets 21 and the lower silicon steel sheets 22. The pin assembly 26 includes a pin 26a, and a pin sleeve 26b is sleeved outside the pin 26a.

[0032] Specifically, the pipeline 1 is made of a non-magnetic alloy.

[0033] Specifically, the pipeline 1 is made by plastic stamping.

[0034] Specifically, cover plates 5 are arranged at both ends of the electromagnetic metering device 2.

[0035] The electromagnetic field of the present utility model adopts the method of single winding + silicon steel sheet attached to a flexible PCB circuit board, which effectively reduces energy consumption and increases battery life; the silicon steel sheet is fixed by using a slot and a plastic buckle, which can avoid interference and save space; there are no component blockages inside the pipe section, and the pressure loss is small.

[0036] It should be noted that an electromagnetic water meter is a precision device that uses the principle of electromagnetic induction to measure water flow. Its design and operating principle are based on Faraday's law of electromagnetic induction, which states that when a conductive fluid (such as water) flows in a magnetic field, an electromotive force will be generated on a conductor perpendicular to the magnetic field direction, and this electromotive force is related to the velocity of the fluid and the magnetic field strength.

[0037] Detailed structural description: An electromagnetic water meter generally consists of the following main parts:

[0038] Measuring pipe: A non-magnetic alloy short pipe is lined with an insulating material, and a pair of electrodes are embedded therein. They are fixed along the pipe diameter direction, and the electrode heads are flush with the inner surface of the lining.

[0039] Excitation coil: The part that generates the magnetic field. Through bidirectional square wave pulse excitation, a working magnetic field with a magnetic flux density B is generated.

[0040] Electrodes: Two electrodes located in the measuring tube are responsible for inducing the electromotive force. When water flows, the ions in the water move in the magnetic field, generating an induced electromotive force, which is then detected and converted into flow information.

[0041] Converter: Converts the induced electromotive force into a readable flow signal, which may include an analog current or a pulse signal for flow control and regulation.

[0042] Display section: Modern electromagnetic water meters are often equipped with an LCD screen to display real-time flow, forward / reverse cumulative total, and possible alarm prompts.

[0043] Power supply system: Some electromagnetic water meters are powered by built-in lithium batteries to ensure long-term stable operation in environments such as water supply pipe networks.

[0044] Protection design: To adapt to harsh working environments, such as high pollution and corrosion, electromagnetic water meters may have an IP68 level of protection to reduce external influences.

[0045] In summary, through its unique structural design and working principle based on electromagnetic induction, the electromagnetic water meter achieves accurate measurement of water flow and has significant advantages in aspects such as automated system integration, durability, and strong adaptability.

[0046] The present utility model provides an electromagnetic water meter. Compared with the double electromagnetic coils of traditional electromagnetic water meters, the present utility model creatively uses a magnetic conductive silicon steel sheet as a substitute for the second coil. The modified device is reasonably and tightly connected, and through the improvement of the structure within a limited space range, the utilization of electromagnetic measurement components is maximized, and the internal core of the traditional electromagnetic water meter is reduced. On the one hand, the cost is reduced, and on the other hand, the volume of the electromagnetic water meter is reduced.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not restrictive. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
