A Wet Gas Metering System Based on the Extended-Throat Venturi Tube [PDF]

open access: yesSensors, 2021
Although the use of a classical Venturi tube for wet gas metering has been extensively studied in the literature, the use of an extended-throat Venturi (ETV) tube has rarely been reported since its first proposal by J. R. Fincke in 1999. The structure of
