  • Miniature differential pressure flow sensor
    Patent number: 10018489
    Abstract: A fluid flow velocity sensor using a differential pressure measurement includes a stack having a tip pointing in a first direction, the stack including first and second plates arranged in parallel one another along the first direction; and a pressure-sensitive diaphragm arranged between the first and second plates along the first direction, the pressure-sensitive diaphragm being spaced apart from the first plate by a first cavity and from the second plate by a second cavity. The first cavity is entirely sealed, except at the tip of the stack, so as to be under a stagnation pressure during operation of the fluid flow velocity sensor. The second cavity is opened so as to be under a reference pressure during operation of the fluid flow velocity sensor. The fluid flow velocity sensor includes a detector to measure a parameter representative of the differential pressure between the first and the second cavities.
