[0024] Please see Figure 3 - Figure 4In this embodiment, a detection rod 304 is vertically positioned at the lower center of the level gauge body 301. A housing 302 is fitted around the detection rod 304. A transmitter 305 is located in the middle section of the detection rod 304, and a float 303 is located at the bottom of the detection rod 304. The detection rod 304 is the core component of the level gauge, used to detect changes in liquid level. It is typically made of high-strength, corrosion-resistant materials to ensure long-term stable operation in various liquid environments. The detection rod 304 integrates a magnetostrictive sensor, enabling high-precision liquid level measurement. The high-strength material and corrosion-resistant treatment allow the detection rod 304 to be used for extended periods even in harsh environments. The float 303 is located at the bottom of the detection rod 304 and floats up and down with changes in liquid level, moving the magnetic element inside the detection rod 304, thereby achieving accurate liquid level measurement. The transmitter 305 is located in the middle section of the detection rod 304 and is responsible for transmitting the physical signal detected by the sensor inside the detection rod 304. The signal is converted into an electrical signal and transmitted to an external device through the connection hole 307. A fixing ring 308 is fitted around the outside of the float 303, and a guide tube 309 is connected to the bottom of the float 303. A weight 310 is provided at the bottom of the probe 304. The fixing ring 308 ensures that the float 303 always moves up and down along the probe 304, avoiding lateral movement or rotation of the float 303 and improving the accuracy of the measurement. The fixing ring 308 can prevent the float 303 from accidentally falling off, increasing the safety of the system. The guide tube 309 can ensure that the float 303 moves along a predetermined path when the liquid level changes, avoiding the float 303 from deflection or jamming. The weight of the weight 310 can ensure that the probe 304 always remains vertical, avoiding measurement errors caused by tilting. The combined design of the fixing ring 308, guide tube 309 and weight 310 ensures the stable movement of the float 303 and the probe 304, improving the accuracy of liquid level measurement.

[0025] During operation, the level gauge body 301 is first installed on the mounting base 201 using quick connector 214 and retaining nut 213. The probe rod 304 is then inserted into the level gauge body 301. After installation, the device is fixed to the top of the container. When the device is activated, the float 303 is positioned above the liquid surface, and the counterweight 310 keeps the probe rod 304 vertical. Inside the probe rod 304 is a magnetostrictive wire, one end of which is fixed to the counterweight 310, and the other end is fixed to the level gauge body 301. Inside the float 303 is a permanent magnet. As the float 303 moves, the position of the magnet changes. When the magnet approaches the magnetostrictive wire, it generates a magnetic field. This causes the magnetostrictive wire to undergo minute deformation. The pulse signal generated by the deformation is transmitted through the magnetostrictive wire to the transmitter 305 inside the level gauge body 301. The transmitter 305 receives the pulse signal from the magnetostrictive wire and converts it into an electrical signal. The processed electrical signal is transmitted to the display panel 306 through the wiring hole 307. When external vibration or impact is transmitted to the device, the damping spring 205 absorbs most of the vibration energy. The spring damper further reduces the vibration transmission, ensuring the stability of the telescopic column 204 and the support plate 207. The suction cup 208 and the shock-absorbing pad 216 provide additional fixation and shock absorption, ensuring that the support plate 207 remains stable in a vibrating environment.

[0026] Through the above steps, the shock-absorbing structure prevents displacement caused by external vibration or impact. The shock-absorbing pad 216 can effectively absorb and buffer vibration energy, reduce the impact of vibration on the level gauge, and ensure that the entire device remains stable in a vibration environment, avoiding measurement errors caused by vibration. The electric push rod 206 is precisely height-adjusted through the electrical control box 210, so that the support plate 207 can always remain horizontal. No matter how the installation environment changes, the height of the telescopic column 204 can be adjusted by the electric push rod 206 to ensure that the level gauge body 301 is always in the optimal installation position. Through convenient installation and disassembly, without complicated tools and steps, this design greatly saves time and labor costs. It solves the problems of unstable fixing of the probe rod 304, which may cause the float to shift or rotate, resulting in inaccurate measurement results. Vibration and shaking can cause changes in the physical properties of the magnetostrictive wire, affecting the magnetostrictive effect and thus affecting the accuracy of level measurement.
