From the angle of easy to mass production,the high precision ultrasonic heat meter is designed.The heat meter MCU selects the low-power chip of MSP430F4371,the chip of time measurement chooses TDC-GP21 with high precision,which combined with ultra-sonic transducer to measure the water flow,and while combined with Pt1000 to measure the inlet and outlet water temperature.The bas-ic meter is designed as U programmer,in addition,the system has two kinds of communication method such as infrared communication interface and M_BUS interface.The experimental results show that the heat meter has lower power consumption,high accuracy and good stability.
