Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing water level gauge is not stable when in use, and the water level gauge will shake due to the fluctuation of the water surface, which greatly affects the accuracy of the measurement. At the same time, the existing water level gauge is installed There are certain defects in this method, that is, after the water level gauge is installed, it is necessary to ensure that the magnetic floating body is aligned with the water surface, but once the existing water level gauge is installed, its position cannot be adjusted, that is to say, the magnetic floating body and the water surface are not necessarily aligned. The accuracy of the measurement is greatly affected, and the practicability is low, and a follow-up magnetostrictive water level gauge for hydraulic engineering piezometers is proposed.
