Abstract

A device for measuring properties of a fluid flow includes a pipe having a first pipe section which includes a fluid flow modifying feature for causing a liquid part of the fluid flow to form an annular layer at an inner wall of a second pipe section arranged downstream of the first pipe section, the second pipe section including a near field probe for applying a low frequency signal to the annular layer and a full volume field probe for applying a high frequency signal into the second pipe section, and a third pipe section arranged downstream of the second pipe section, the third pipe section including a resonance enabling element that together with at least the second pipe section provides a resonator which captures parts of the frequency range of the full volume field probe.
