555 ultrasonic liquid level indicator circuit
As shown on the figure 7-30, this circuit consists of the ultrasonic transmitting circuit and receiving circuit. Its hydraulic measurement is better than others, because the measured liquid's concentration and conductivity don't have effects on its ultrasonic. The ultrasonic transmitting circuitconsists of the 555,R1,RP1,C1 and ultrasonic generation. The receiving circuit consists of VT1,VT2 and detection circuit. If the liquid level is more close to the receiver sensor, the angle of the voltmeter will be bigger.
