Abstract

Ultrasonic system for level and distance measurement is a way of measurement that is not only efficient but is also cost effective, which make it easy to be employed in number on different situations and configurations whenever is seen fit. Day after day we are faced with a problem of making an accurate measure of the distance of objects that are located in remote places and where access to those places is inconvenient to use traditional ways of measurement. For all over the years, it has always been in the interest of engineers to be able to use sophisticated systems t be able to do measurement. One of the methods that this paper describes is the Time of Flight Method (TOF). It is based on the reflection of sound waves, which makes the wave propagation the base of the project. The technique is pulse-echo method, where wave is emitted from the ultrasonic transmitter and its corresponding echo received for further analysis by ultrasonic receiver. Water is a very good reflector of ultrasonic waves, and therefore the project this report describes is merely a system that transmits and receives the echo reflected at the surface of the water if liquid measurement is being performed. In the case of distance measurement, is also used the same principle, so long the it is know what is being targeted by the system in hand. A microprocessor is used in this project which takes on the tasks of triggering the transmitter and calculating the distance by analysing the returned echo.
