1. A sensor arrangement for providing a sensor signal indicative of a vapor quality of a medium flowing within a conduit, comprising
a horizontally arranged portion of said conduit extending axially,
a sensor arranged in thermal contact with a wall of said portion of said conduit, said sensor comprising a heating element and a temperature sensing element, and
processing means disposed to deliver the sensor signal based on an output of said temperature sensing element,
wherein said sensor comprises a sensor body made of a metal material, said heating element and said temperature sensing element being arranged in thermal contact with said sensor body,
wherein said heating element is surrounded by said sensor body such that, along a radial plane, a part of said sensor body is arranged between said heating element and said horizontally arranged portion of said conduit; and
wherein said temperature sensing element is surrounded by said sensor body such that, along a radial plane, a part of said sensor body is arranged between said temperature sensing element and said horizontally arranged portion of said conduit.
