Flow grid of sensor arrangement for determining intake air mass of combustion engine, has grid cell with fluid medium guide surface extended over entire cross-section of flow tube while generating vortices along fluid medium flow

摘要

The flow grid (112) has several grid cells (122) through which the fluid medium is allowed to pass through. Each grid cell is comprised of a fluid medium guide surface (132) along main flow direction, and is extended over the entire cross-section of a flow tube while generating several vortices along the flow of fluid medium. The grid cells are arranged rotationally symmetric around parallel axis (114) of main flow direction. An independent claim is included for sensor arrangement.
