FIELD: measuring equipment.
SUBSTANCE: group of inventions relates to a radar level gauge system and to a method for determining level of filling a tank (reservoir) with a product. Method of determining level of filling a reservoir with a product comprises steps of generating and sending a transmitted signal, providing distribution of transmitted signal along its propagation path in direction of product surface, wherein said path has first section adjacent to transceiver, for which signal propagation parameters are known, and second section adjacent to first section, receiving reflected signal formed as a result of reflections from boundaries of impedance jumps, crossed by the transmitted signal, including from the product surface, based on the time shift between the transmitted and reflected signals, determining the first measurement ratio, based on the first measurement ratio and known signal propagation parameters, the second measurement ratio is determined and based on the second measurement relationship, the filling level is determined.
EFFECT: technical result is increase in reservoir filling level measurement reliability.
