Patent number: 11104147Abstract: A differential pressure sensor is used for measuring or identifying a pressure difference, for example to determine a movement or speed of fluid in a fluid conduit or printer re-circulation conduit. The differential pressure sensor determines the difference between an air pressure and a fluid pressure, wherein the fluid is moving in a flow channel. The flow channel includes a surface conveying a fluid between a first port and second port. An opening in the surface of the flow channel provides a fluid communication between the differential pressure sensor and fluid. Moreover, the sensor is arranged in air communication with the pressure box, such as to allow the differential pressure sensor to identify the pressure difference between the air pressure in the pressure box and the fluid pressure in the flow channel.Type: GrantFiled: April 19, 2017Date of Patent: August 31, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: David Butinya, Marta Coma Vives, Albert Crespi Serrano, Joan-Albert Miravet Jimenez
