The picture shows the ultrasonic wave liquid level indicator circuit. This circuit is made up by ultrasonic wave transmitter circuit and receiving circuit. Because the ultrasonic wave features that it would not be influenced by the concentration and conductivity of the tested liquid, this circuit would have better and higher accuracy than normal contacted liquid level displaying circuit. The ultrasonic wave transmitter circuit is made up by 555, R1, W1, C1 and ultrasonic transmitter head UCM40T. The ultrasonic receiving circuit is made up by the receiving head UCM40R which is corresponding to the transmitter head, cascaded amplifier BG1 and BG2 and the detecting circuit. When the liquid level close the receiving head, the voltage meter's deflection angle would gain. And the closer to the liquid level, the bigger the corresponding deflection angle would be.
