In this paper ,the innovational research is based on widely absorbing patents and applied technique at home and abroad and pointing out the disadvantage and ameliorative method of heat/low meter. According to the principle of therrnopile, and the three - dimensional loop wire laying is substituted by new - style plane wire laying. The construction and manufacture of new - style heat flow meter is declared. The new method will facilitate the manufacture and reduce the cost and the high precision feeler is assured by consistent line length, capacitance, resistance and inductance and the cost of determination in present demarcation will be cheaper than traditional feeler of heat flow meter. The high precision energy saving detection instrument is provided for the field of heat energy.
