A set of electronic components in the device that send the measurement
signal through some signal filters. They identify and measure the level of the tank
contents.
Tank Bottom Following (TBF) mode is an alternative measurement mode. It allows
the device to measure tank contents with very low dielectric constants. TBF
mode uses the reflection of the tank bottom to indirectly measure the level of
the tank contents.
