Paper Title:
Research on High-Accuracy Low-Power Ultrasonic Flow Measurement and Instrument
  Abstract

In order to solve the problem of low accuracy and high power consumption, A new ultrasonic flow measurement method was proposed in this paper. With this method, the influence of the delay-time in the circuit was eliminated,the temperature of fluid was compensated automaticly and the accuracy of the flow measurement was improved. The ultrasonic flow-meter was designed with the micro-power timing chips TDC-GP2 and MSP430F435, which reduced the power consumption effectively. The experimental results showed that the accuracy of the ultrasonic flow-meter was 1.5% and the average operating current was lower than 35uA.
