Its accurate and stable measurement results are crucial to industrial production and process control. For example, an electromagnetic flowmeter with application number "202410137671.6" is mainly composed of a first arm body, a first drive assembly and a second drive assembly. When in use, the two first arms can be extended along the length direction of the pipe body to press against and fix the first connecting part of the excitation coil, and the two second arms can be extended along the circumferential direction of the pipe body to press against and fix the second connecting part of the excitation coil. The first drive assembly is used to synchronously drive the two first arms to extend, and the second drive assembly is used to synchronously drive the two second arms to extend. The adjustment mechanism is used to synchronously control the first drive assembly and the second drive assembly, or to control the second drive assembly alone. The electromagnetic flowmeter can save the assembly time of installing the excitation coil on the large-diameter pipe body, and shorten the overall assembly time of the electromagnetic flowmeter.

[0003] In the prior art, an electromagnetic flowmeter is installed at one end of an output pipe, and the flow rate of the water flow is calculated by using the fact that the water flow is proportional to the electromotive force of the electromagnetic.
