Abstract

This invention relates to a measuring instrument for measurement of a flow (1) comprising—a dielectric resonator sensor (3) arranged in a pipeline (2), said resonator (3) having a surface (4) facing a flow volume, —a sensor drive unit (12) being coupled to said sensor (3) and which is adapted to provide a driving or excitation signal to said sensor (3) resulting in the excitation of an electromagnetic resonance in said sensor causing a fringing electromagnetic field (5) adjacent to said surface (4) facing said wet gas flow (1), —a recording unit (10) coupled to said sensor (3) and which is adapted to measure a resonance property of said sensor (3) while said wet gas flow (1) moves past said sensor surface (4), and—a processing unit (11) which is adapted to estimate a property of at least a part of said wet gas flow (1).
