Claims (6)

1. Устройство для измерения массы протекающей среды, в частности, массы всасываемого воздуха в двигателях внутреннего сгорания, содержащее расположенный поперечно к потоку держатель, выступающий из стенки, ограничивающей поток, в поток, причем измерительный канал, выполненный в держателе, омывается протекающей средой, в которой размещен термочувствительный измерительный элемент, отличающееся тем, что в держателе выше измерительного элемента (20) по ходу потока расположено препятствие (50) потоку, вызывающее эффективное, точно определяемое расслоение (54) потока в измерительном канале.1. A device for measuring the mass of a flowing medium, in particular, the mass of intake air in internal combustion engines, comprising a holder transverse to the flow, a protruding protruding from the wall restricting the flow into the stream, the measuring channel being made in the holder being washed by the flowing medium, which hosts a thermosensitive measuring element, characterized in that in the holder above the measuring element (20) along the flow there is an obstacle (50) to the flow, causing an effective, accurately defined bundle (54) of the flow in the measuring channel. 2. Устройство по п.1, отличающееся тем, что препятствие (50) потоку расположено в зоне впускного отверстия (36) измерительного канала (33). 2. The device according to claim 1, characterized in that the obstacle (50) to the flow is located in the area of the inlet (36) of the measuring channel (33). 3. Устройство по п.2, отличающееся тем, что препятствие (50) потоку выполнено в форме кромки (51) выступа. 3. The device according to claim 2, characterized in that the obstacle (50) to the flow is made in the form of an edge (51) of the protrusion. 4. Устройство по п.3, отличающееся тем, что вслед за кромкой (51) выступа по ходу потока в стенке (38), ограничивающей измерительный канал (33), выполнено углубление (52). 4. The device according to claim 3, characterized in that after the edge (51) of the protrusion in the direction of flow in the wall (38) bounding the measuring channel (33), a recess (52) is made. 5. Устройство по п.1, отличающееся тем, что препятствие (50) потоку выполнено в форме проходящей в потоке проволоки. 5. The device according to claim 1, characterized in that the obstacle (50) to the flow is made in the form of a wire passing in the stream. 6. Устройство по п.5, отличающееся тем, что проволока размещена в зоне впускного отверстия (36) измерительного канала (33). 6. The device according to claim 5, characterized in that the wire is placed in the area of the inlet (36) of the measuring channel (33).
