In this study, we classify the difference of heat transfer coefficient regarding to the temperature using thermal mass flowmeter. In using gas, the experiment condition regarding to temperature was generally ignored due to its characteristic of properties. In this experiment we focused on using water which properties(density, specific heat) are relatively high than gas to figure out the characteristic changes in terms of various conditions of temperature. The experiment was carried out at a certain range(20℃, 50℃ and 80℃). By changing the velocity of water at each temperature, the heat transfer coefficient was measured at 8자형 sensor which have separated RTD and heater. Throughout this study, we can analyze the characteristic curve between fluid and temperature and obtain specific experimental equation.
