Abstract
A device for measuring the mass of a flowing medium with a temperature-dependent measurement element has a measurement conduit whose faces, which extend perpendicular to a surface fixed by the measurement element, are inclined and approach each other in the flow direction of the medium in the measurement conduit. The invention is provided for measuring the mass of a flowing medium to measure the intake air mass of internal combustion engines.
Claims10
A device for measuring the mass of a flowing medium, in an intake air mass of internal combustion engines, comprising a temperature-dependent measurement element that the flowing medium circulates around, said measurement element is disposed in a measurement conduit extending in the device from an inlet to an outlet, said measurement conduit is adjoined by a deflection conduit, wherein the measurement conduit has two faces (37, 38) which extend transversely to the measurement element (21), and that faces (37, 38) approach each other in a direction of the flow in the measurement conduit, the measurement conduit (30) having two additional faces (39, 40) which are disposed lateral to a surface(24) of the measurement element (21).
