To achieve liquid level measurement, two optical ranging instruments are symmetrically arranged along the diameter of the liquid storage tank. The distance between the two optical ranging instruments is the radius of the storage tank, and the distance between each optical ranging instrument and the storage tank wall is half of the radius of the storage tank.

[0045] Although the optical distance measuring device can measure the distance between the optical distance measuring device in motion and the liquid surface, due to the certain distance between the optical distance measuring instrument and the storage tank wall, when the liquid in the storage tank fluctuates, the true liquid level elevation cannot be obtained. To solve the above problem, an embodiment of the present invention provides a dynamic liquid level monitoring method based on optical distance measuring technology.
