Title: MEASUREMENTS DEVICE
Abstract:
The present invention provides a device for measuring properties of a fluid flow in a pipe, comprising a first (1), second (2) and third pipe section (3), and where the first pipe section (1) comprises a fluid flow modifying feature arranged such that, during use, a liquid part of the fluid flow will form an annular layer (4) at an inner wall of the second pipe section (2), and the second pipe section (2) is arranged downstream of the first pipe section (1) and comprises at least one near field probe (5) having a first frequency range, and at least one full volume field probe (6) having a second frequency range, the upper limit of the first frequency range being lower than the lower limit of the second frequency range; the third pipe section (3) is arranged downstream of the second pipe section (2) and comprises a resonance enabling element (8), such that said element (8) and at least the second pipe section (2) provides a resonator able to capture parts of the frequency range of the full volume field probe (6).
