The invention relates to a pressure probe (100) for characterising the pressure and/or differential pressure in a fluid, and all derivatives like for instance flow rate. The device (100) comprises a front side adapted for facing an upstream direction of the fluid flow, a bulbous part (102) adapted for creating a region of low pressure, also called wake, and a flow detachment means (120). The front side allows creation of a region of high pressure. It has a planar shape or the shape of a recess. The device thus allows to be substantially flow angle independent, to be Reynolds number independent in a wide range of flow velocities and to obtain a large differential pressure gain. |
