| Abstract: | Based on a general flow equation for the variable area flowmeter & the capacitive angular position transducer, this paper describes a new type of smart metal tube variable area flowmeter which has realized a high accurate measurement. Also its main parts are illustrated in detail, including a designed frame, a designed model of capacitive angular position transducer, signal processing, smart functions, prototype meter calibration and analyzing error. All of the three experimental prototype meters obtained a high accuracy. |
