Abstract
The invention relates to a liquid level detector, in particular to a detector capable of effectively eliminating the influence of foam on the liquid level. The foam-resisting liquid level detector comprises a range finder, an installation board, a guiding rod and a floating rod, wherein the guiding rod is fixed by the installation board, and the floating rod is of a hollow tubular structure and floated on the liquid level to be detected. Partial rod body of the guiding rod enters the tube body of the floating rod to lead the floating rod to be vertical. The laser range finder is installed right above the guiding rod for measuring the distance between the laser range finder and the bottom of the floating rod. The foam-resisting liquid level detector measures actual changing of the liquid level by measuring the relative displacement of the floating rod. The relative liquid level position of the floating rod in industrial liquid is totally free of influence from foam and moves vertically along changing of the liquid level, so that the influence of the foam on measuring of the liquid level is totally avoided, and high-accuracy measuring on changing of the liquid level is achieved.
