liquid level Alarm
Here is a simple circuit for Liquid level alarm. It is built Around two BC547 transistors(T1 and T2) and two timer 555 ICs (IC1and IC2). Both IC1 and IC2 are wired in astable multivibrator mode. TimerIC1 produces low frequency, while timer IC2 produces high frequency. As a result, a beeping tone is generated when the liquid tank is full. Initially, when the tank is empty, transistor T1 does not conduct. Consequently, transistor T2 conducts and pin 4 of IC1 is low. This low voltage disables IC1 and it does ....etc

Liquid Level Measurement Based on Ultrasonic Echo Characteristic
introduction
Ultrasound is high frequency mechanical vibrations or pressure waves
Uses sound waves(>20000Hz)
Sound waves are transmitted as a series of compressions and rarefactions
Wave propagation is longitudnal and mechanical displacement in same direction
About Ultra Sonic Technique
Ultrasonic level sensors are used for non-contact level sensing of highly viscous liquids, as wel ....etc
