Radar level sensor work with high frequency radar which are
guide along a probe,As the pulse impact the medium the
impedence changes and part of the emitted pulse is reflected
The time between pulse launcing and recieving is measured
and level calculated.
Ultrasonic level sensor works on sound wave principle,
direct sound wave brust on onto the surface of the material
whose level is to be measured, echos of these waves returns
to the transducer which perform the calulation to convert
the distance of wave travel.
