Abstract
A radar level gauge system comprising: a transceiver; a tank feed-through; a power divider to divide a transmit signal into a first transmit signal and a second transmit signal; a first probe member configured to guide the first transmit signal and to return a first reflection signal, said first probe member providing a first relatively large average attenuation; a second probe member configured to guide said second transmit signal and to return a second reflection signal, said second probe member providing a second relatively small average attenuation; measurement signal forming circuitry for forming a measurement signal comprising a first set of echo indicators indicating reflection of said first transmit signal, and a second set of echo indicators indicating reflection of said second transmit signal; and level determining circuitry for determining a first level based on said first set of echo indicators, and a second, deeper, level based on said second set of echo indicators.
