Development of Heat Flow Meter and Research on Amelioration of International Advanced Technique

Heat flow meter is an apparatus measuring the transfer of heat energy. In developed countries it is used in detection of energy consumption and safety system of electricity generation, steel making, chemical engineering and building heating and air-conditioning, but it is just a start for its application in China. The research of heat flow meter with own intellectual property is based on the urgent need of energy saving in China. The innovational research must be based on improvement of current technique. In this paper, the progress of heat flow meter is reviewed and the sort and principle of heat flow meter is introduced. The best feeler and the crucial technique of thermopile for heat flow meter in thermal resistance are selected. The disadvantage and ameliorative method is pointed out. At last, a Chinese patent is granted to the authors.
