摘要

The system has a washing liquid container for mounting in a motor vehicle with a reservoir chamber (2) for storing washing liquid with a connection to a measurement chamber (6) with a significantly smaller volume than the reservoir chamber. The measurement chamber contains an arrangement for detecting freezing of the washing liquid and is mounted in a position cooled by the wind caused by vehicle motion.
