Reflected pulse signal along the cable or rod probe type transmit to the instrument electronic circuit parts, themicroprocessor processes the signal, identify the microwave pulse echo generated in the material surface. Correctidentification of the echo signal are completed the implementation by the pulse software, D, the distance from thematerial surface and the pulse travel time T is proportional:

D=C×T/2

Where C is the speed of light because the empty distance E is known, the level L is:

L=E-D

By entering the empty height of E (= zero),full tank height F (= hundred) and theapplication to set some parameters, applicationparameters will automatically adapt the instrumentto measure the environment, corresponding to the 4-20mA output.
