ABSTRACT:
The location of a thermal transmition zone in a water storage tank is detected by a number of temperature responsive electrical elements arranged on the exterior surface tank, out of contact with the water, and at selected locations thereon corresponding to thermal transition zone levels within the tank; visual indicating means are connected to the sensing element and are in an arrangement to correspond to the location of the elements on the tank such that, upon the temperature sensing elements detecting the location of the thermal zone, a corresponding visual indication is provided.
