Part of pulse signal reflection along the cable or rod probe conduction to the instrument of electronic circuit, a microprocessor to signal processing, to identify the microwave pulses are generated on the material surface echo. Echo recognition is completed by the pulse software, from the material surface distance between D and T pulse is proportional to the time travel:
D=C×T/2
Where C is the speed of light
Because of the air tank is a known distance E, L
L=E-D
