Abstract: According to the similarity theory of fluid mechanics to establish a raft labyrinth water storage model experiments, the model tank internal sets up multiple temperature sensor, analyzes the temperature distribution inside the water tank, the analysis and design flow of dead zone size and temperature measuring point layout position are given. At the same time, the flat cable type temperature sensor is set. The application of cable type temperature sensor in the labyrinth of water storage projects is analysed.

Key words: labyrinth water cool storage, dead zone, Froude criteria, cable type temperature sensor
