Abstract
Disclosed are a liquid level switch system and a liquid level measurement method. The liquid level switch system has a transmitting probe, a receiving probe and a main unit. The transmitting probe is located at a warning position on the outer wall of a tank body, the receiving probe is located on the outer wall of the tank body, and the transmitting probe and the receiving probe are respectively connected to the main unit by means of cables. A piezoelectric plate is placed on an inclined block to change the incident angle of an ultrasonic signal entering the tank wall so as to generate a longitudinal wave signal and a transverse wave signal, and the main unit judges, according to a signal strength difference value between a longitudinal wave receiving signal and a transverse wave receiving signal, whether the liquid level of the tank body reaches the warning position.
