Abstract
This application discloses a wet gas flow rate metering method and device thereof. The Coriolis mass flowmeter measures a total mass flow rate Qm, a mixed density ρmix, and a medium temperature T; a combination of sensors measures a differential pressure ΔP between an inlet and an outlet; a flow rate calculation module performs multi-physical field coupling calculation to obtain an average gas density ρg; according to the mixed density ρmix, the average gas density ρg, and a liquid density ρl, a mass liquid content ηm of a mixed medium is calculated, and the total mass flow rate Qm is corrected by the mass liquid content ηm, the medium temperature T and the average pressure P to obtain a corrected total mass flow rate Qm′. According to the total mass flow rate Qm′ and the mass liquid content ηm, a two-phase flow rate is calculated.
