<p>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.</p> |
