A vehicle urea tank associated with a sensing chamber for acoustic quality and level sensing

摘要

The device (2) for measuring a quality of a urea solution of a vehicle urea tank or of a urea solution coming from such a tank, has:- a chamber (24),- at least one ultrasonic transceiver (32) arranged for vertically emitting a ultrasonic wave in the chamber, and- a deflector (34) extending in the chamber above the transceiver.;The chamber has an inlet (33) for filling the chamber with a urea solution so that a level of the solution in the chamber reaches at least the deflector.
