[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0013] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0014] like Figure 1 As shown, a self-cleaning chemical instrument liquid level measuring device includes a measuring device body 1, a display screen 2 for displaying monitoring data on the measuring device body 1, an extension tube 3 at the bottom of the measuring device body 1, a vibration chamber 6 at the lower end of the extension tube 3, a vibration device inside the vibration chamber 6, and a liquid level probe 5 below the vibration chamber 6. Power and signal lines pass through the extension tube 3. By setting an extension tube, a vibration chamber with a built-in vibration device, and a liquid level probe at the bottom of the measuring device body, and by passing the power and signal lines through the extension tube, a self-cleaning vibration function is achieved to reduce the impact of contamination and scaling on the measurement.
