Abstract :
In vortex flowmeter, the signal is slim with large noises if the velocity of the fluid is low, and it can be detected by a signal processing method based on flow momentum. When the velocity increases, the method based on threshold comparison can be applied. Considering of the signal in the whole range, the paper will introduce a signal processing method applied both in the low frequency and in the high frequency.
