In order to realize real-time monitoring of temperature during the model test in warm-water discharge of power plant,a multi-channel temperature collection system is developed. The system is mainly composed of acquisition sensor,data acquisition module and data storage and display software. The system has advantages of simple structure,low cost,convenient manipulating,and it can change the gauging points arbitrarily according to the demanding of temperature measurement on the spot. Result from test made in the thermal effluent from power plant shows that the system is accurate and reliable to meet the test requirements. The system can observe the surface and underwater temperature of the model waters in a real-time. It also can provide good technical support for the physical model test of thermal drainage in optimization of engineering design and environmental impact assessment.
