Dear friends,
I'm working on a project for measuring the level of liquid in a tank
with ultrasonic sensors.
In this project i need a measurement resolution about 1mm and the
maximum range of measuring is about 4m.
First I want to know if resolution depends on the frequency of the
sensor or the electronic circuit that measures the time of going and
returning of signal.
Second I have found an article that has measured the level with phase
shift with great resolution but the maximum range is 90cm.I will
appreciate any information about this method and it's relation with
resolution and the way one can extend the maximum range to 4 m.
Thanks in advance
Regards
S.Azimi
