Abstract:
A device for measuring the mass of a medium flowing in a line, the device comprising:a measurement conduit (20) positioned in the intake line so as to admit a portion of the fluid flowing through the intake line, a temperature-sensitive measuring element (30) disposed in the measurement conduit and about which the portion of the flowing fluid circulates, the measurement conduit including a first end and a second end, a first deflection element (41) positioned near the first end, and a second deflection element (42) positioned near the second end, said deflection elements deflecting the portion of the flowing fluid, the deflection elements (41, 42) being positioned essentially symmetrically with respect to the measuring element (30), such that the portion of the flowing fluid traverses a substantially symmetrical path through the measuring conduit, whether it traverses a path from the first end to the second end, or from the second end to the first end, and at least one particle-absorbing element (50) disposed on a surface of a wall defining said measurement conduit in the region of the wall which deflects the flowing fluid.
