Paper Title
A Possible Water Depth Measuring System Using Ultrasonic Wave
Abstract
-To measure the depth of water or detection
of obstacle present inside the water, a simple technical
method is used. In this method, transducer of both
transmitter and receiver are placed just below the
surface of water. Ultrasonic wave are generated by the
generator using piezoelectric crystal as transducer.
This ultrasonic sound vibration is transmitted for few
microseconds into water. The transmitted pulses are
either reflected from the bottom surface of water or
reflection due to any obstacle present inside the water.
The reflected pulses are received introducing some
time delay, by using the same transducer. By
measuring the time delay between transmitted and
received pulse, we can decide the depth of water by
using the formula-
Speed = Distance / time (m/s)
Distance (depth) in meter = 1480 * time in second
(ultrasonic velocity in water is 1480 m/s.)
