Abstract

A new ultrasonic flowmeter based on TDC-GP1 was introduced.The chip TDC-GP1 can transform time intervals into digital values with very high precision;it is the hardware core in the design of this flowmeter.In the discussion of software,questions about nonlinear corrections and temperature compensation were also taken into account.The metrical results of practical experiments are very favorable,and the ultrasonic flowmeter has a lot of merits such as low power consumption,good run stabilization,high measured precision,so the innovative ultrasonic flowmeter has wide applied foreground.
