Definitions

  • Such devices for introducing a freezable liquid into the exhaust system of a motor vehicle are known ⁇ be.
  • a device in which an aqueous urea solution for NO x reduction is metered into the exhaust gas.
  • the urea solutions used for this purpose consist of distilled water and 32.5% urea. This solution freezes at -11 ° C. If the motor vehicle is lowered and the temperature of the fluid drops below -11 ° C, the solution freezes in the tank, whereby the fluid expands in the frozen state by about 11%.
  • the transmitter / receiver is arranged on the underside of the tank bottom.
  • a plate flange
  • the ice protector of this sensor is mounted on the bottom plate of the sensor and has an opening over the second mirror so that the sound waves can be radiated upward through the opening in the tank and reflected back from the surface of the urea solution.
  • the ice protector except for the above-mentioned opening is substantially closed ⁇ ge.
  • the ice protector is formed integrally with a bottom plate of the sensor or the tank bottom. If the sensor has its own bottom plate, which is located on the bottom of the tank, the bottom plate and ice protector form a unit. If the sensor does not have its own ground and if the corresponding part of the sensor is attached directly to the bottom of the tank, it forms
