Abstract：An ultrasonic heat meter system which is based on the TDC-GP2 is given a particular introduction.It is a kind of domestic ultrasonic flow meter that combines the flow measurement and the temperature measurement together. The measurement principles for heat,flow rate and temperature are described.Moreover,the method of heat meter design is introduced in detail.Ultrasonic flow measurement technology provides a non-intrusive method to measure flow rate, and also has some outstanding advantages,such as low pressure drop,low energy consumption and high measurement precision.Comparing to the classical mechanical heat meters,it overcomes defects in measurement precision.In addition,it is hard on damage.More importantly, the stop mode of microcontroller is used to lower the power consumption, and the ultrasonic processing circuit is powered only when measuring.
