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

INTRODUCTION

Sound waves in air are longitudinal waves. The disturbance that propagates in air is a change in the local air pressure (or equivalently density) above or below the average pressure

a region of higher air pressure in the wave is called a condensation, while a region of lower air pressure is called a rarefaction

The speed of sound in air depends on several factors, including the air temperature and pressure. ....etc

Simultaneous Noncontact Measurement of Water Level and Conductivity
water level and conductivity measurement is important in many applications. geophysics, ocean engineering, and the oil industry also rely on this. The gas/oil/water separation can be an example for this. for those application, the method of Noncontact measurement is suitable. For measuring the level, techniques such as Capacitance, radar, ultrasonic, and laser have been used. measurements of level and conductivity simultaneously has no tbeen possible. a novel inductive ....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
