[0001] The utility model relates to laser level gauge technical field, concretely is a laser level gauge with outer cover type protection structure. BACKGROUND

[0002] Laser level gauge utilizes the linearity and coherence of laser, and the inclination angle of horizontal plane can be calculated by measuring the offset of laser in two directions. Specifically, the laser transmitter emits laser, which is divided into two mutually perpendicular lasers by a beam splitter, and is respectively reflected on two position reflecting mirrors with a certain distance. When the horizontal plane is inclined, the reflection angles of the two lasers are different, resulting in the phase difference of the two lasers on the receiver. The inclination angle can be obtained by measuring the phase difference.
