关 键 词：vortex flowmeter signal processing dual-channel
摘 要：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 *** the velocity increases,the method based on threshold comparision can be *** 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.
