| Abstract: | The measurement principle of the travel time difference method for the ultrasonic flow measurement is analyzed. A signal processing method based on zero-crossing detection and integral principle is depicited, which simplifies the signal processing, reduces the consumption. At last, some low-consumption ultrasonic flow measurement stepes are presented, especially the design of working timing. |
