Abstract: A urea concentration sensor reflector system includes a urea concentration sensor reflector assembly including a reflector having an upwardly convex dome shape integrally connected to and supported by multiple legs. The reflector includes a concave-shaped inner surface. The multiple legs are connected to and support the urea concentration sensor reflector assembly to an upward directed surface of a bottom tank wall of a urea storage tank. A sound wave generator and receiver is fixed to the bottom tank wall directly below and centrally aligned with the reflector. The sound wave generator and receiver generates ultrasonic sound waves directed upwardly toward the reflector. A concentration of a liquid urea in the urea storage tank is determined based on a time for the ultrasonic sound waves to travel to the reflector and return as echo signals to the sound wave generator and receiver, and a temperature of the liquid urea.
