Abstract :
This paper analyses the defects in the construction of conventional Annubar flowmeter and explores a new Annubar flow sensor with piezoelectric crystal. A new detection scheme is also decided on the base of theoretical analyses and a great number of experiments. An integrated Annubar flowmeter whose core is PIC microprocessor is developed in order to lower costs
