Definitions
- the invention relates to a device for measuring the
- FIG. 2 shows the inlet, deflection and outlet channels in the measuring housing
- FIG. 3 shows a flush transition from sensor carrier and measuring channel
- 4, 5 are each a section of Fig. 1,
- a dashed area 34 which runs parallel to the main flow direction 3, forms with the edge area of the inlet duct facing the support part 7 a shaded area 33, with which only a few or no dirt particles or liquids reach.
- Outlet opening 12 the surface of which forms an angle ⁇ with the main flow direction 3 through which the medium leaves the measuring channel again.
- the outlet opening 12 has a larger cross section than the outlet channel 19, which improves the pulsation behavior.
- FIG. 3 shows two examples of how a flush transition 50 between an outer surface of the sensor carrier 9 and an edge surface 54 of the inlet channel 13 is achieved.
- the illustration results from a section along the longitudinal axis 8.
- FIG. 3a there is no recess in the edge surface 54 of the inlet channel 13.
- FIG. 3a Between an end face 47 of the sensor carrier 9 and an edge surface 54 of the inlet channel 13 closer to the outlet channel 19 there is a
- Main flow direction 3 seen, axially tapered in order to open a first section 16 of the deflection channel 15 with a smallest cross section at the outflow opening 14 m.
- the tapering means that an undisturbed, uniform parallel flow can prevail in the area of the measuring element 10.
- the inlet opening 11 of the inlet channel 13 has a rounded edge 78, shown in FIG. 5.
- the deflection channel 15 composed of the first section 16 and the second section 17 preferably has a rectangular cross section, which corresponds approximately to the cross-sectional area of the inlet opening 11 of the inlet channel 13, so that the flow cross-section at one of the outflow opening 14 between the inlet channel 13 and the deflection channel 15 Level 76 abruptly increased.
- FIG. 5 shows a section along the line V -V in FIG. 2, but without sensor carrier 9, with a front region 39, which is located in front of the inlet opening 11.
- a side wall 77 of the inlet duct 13 has an edge 78 in the front region 39. This edge is beveled in such a way that inflowing particles, e.g. Dirt or liquids are reflected away from the inlet opening 11.
- the tapering of the inlet channel 13 through the side surface 73 can also be seen.
- the opposite side surface of the side surface 73 is formed by the cover 49 (FIG. 3). In the edge surface of the outlet channel 19 closer
- the inlet channel 13 is the recess 38.
- the step 76 has a height of 1 mm, for example, and could be reduced by tapering all the edge surfaces of the inlet channel 13 compared to the predecessor model of the device 1 in order to avoid thicker walls and the associated manufacturing problems.
- Cross-sectional contour coincides with the upstream end 63 of the outlet opening 12 with respect to the main flow direction 3.
