Abstract
A water tank liquid level electronic measuring system comprises a water tank. A vertical guide column is arranged in the water tank. A bowl-shaped floating body is arranged in the water tank. A through hole is formed in the center of the floating body. A water blocking cylinder is arranged at the upper portion of the through hole. The guide column penetrates through the through hole and the water blocking cylinder. An ultrasonic probe is arranged in the floating body and faces towards the lower side. The output end of the ultrasonic probe is connected with the input end of a processor. The output end of the processor is connected with a communication module which is connected with a display screen. In the system, by means of an ultrasonic measurement principle, the water level situation can be measured in real time. The floating body moves up and down along with the change of the water level, the ultrasonic probe sends out ultrasonic waves and records the echo receiving time t, the water level height h=vt/2, and v is the velocity of ultrasonic waves in liquid. The water level at any position can be measured, and the measurement result is precise. The measurement result is directly put on the display screen through communication.
