Abstract: The present invention relates to a fluid measuring device comprising a capillary device and a non-linear response device. The capillary device typically having a flow channel comprising a contraction with a sidelet upstream and sidelet downstream of the contraction, the sidelets each comprises a pressure sensor arranged to determine the pressure drop over the contraction, the geometry of the flow channel of the capillary device being adapted to provide a flow response by the linear effects in the fluid, with the least response from the non-linear effects in the fluid. The non-linear response device typically having a flow channel connected to the flow channel of the capillary device, the flow channel of the non-linear response device comprising sidelets arranged to determine a pressure drop over at least a part of the flow channel, wherein the geometry of the flow channel of the non-linear response device being adapted to provide a flow response primarily driven by the non-linear effects in the fluid.

Abstract: The invention relates in particular to a device for determining one or more fluid properties of a fluid. The device preferably comprises a flow distributor comprising a cavity, an inlet to the cavity, one or more outlets from the cavity, and one or more flow deflecting elements present in the cavity and/or one or more flow dividing wall elements of the cavity, wherein the one or more flow deflecting elements and/or the flow dividing wall elements being arranged in such a manner that it provides sub-streams of different strength through the outlet. Furthermore, the device comprises an analyzer downstream of the outlet of the flow distributor comprising means adapted to provide a read-out indicative of the strengths of sub-streams.
