Abstract

A kind of ultrasonic flowmeter using for the pipe flow measurement is designed based on

TMS320F28335 in this paper. The system hardware consists of the following parts: the core board,

ultrasonic signal transmitter and receiver circuits, switch circuit, ultrasonic transducer, signal

acquisition circuit based on ADS805, human-computer interaction module and power supply

module, etc. The system use the method of time difference for pipeline flow measurement and the

time difference is calculated by the time-delay algorithm of SCOT weighted generalized

cross-correlation. The ultrasonic flowmeter has the features of high testing speed, high precision

and low cost, etc.

Keywords: C2000,Ultrasonic, Flow, Generalized Cross-Correlation Algorithm
