Abstract
The present disclosure discloses a method for determining a reflective surface of a steering gear and a focusing steering gear of an external level gauge. The method includes: obtaining a focal length and a specific reflection angle (); determining an 0step reflective surface () of the reflective surface of the steering gear based on the focal length and the specific reflection angle; determining an adjacent step reflective surface () by a geometric method based on the 0step reflective surface; and if a number of steps of the reflective surface of the steering gear reaches a preset value, determining the reflective surface () of the steering gear based on the 0step reflective surface and the adjacent step reflective surface. According to the present disclosure, a liquid level can be measured at an outer side of a side wall of a vertical liquid storage tank.
