“…Several theoretical studies (Boyer and Lemonnier, 1996;Werven et al, 2003;Rosa and Morales, 2004) and experimental researches (Silva et al, 1991;Rosa and Morales, 2004;Steven, 2002;Zhang et al, 2005) have been carried out and a number of correlations have been proposed to estimate gas-liquid flow from pressure drop measurements across a venturimeter. The studies include air-water flows (Soubiran and Sherwood, 2000;Gaston and Reizes, 2001), oil-gas flows 2005) and wet gas metering (Steven, 2002;Xu et al, 2003).…”

“…A Venturi meter is one important kind of the DP meters that have been commercially used in the oil-gas industry. Owing to the advantageous properties of little pressure loss, wide flow range and successful application in many industrial fields, Venturi meters have been widely employed in the field of wet gas metering since 1990s (Boyer and Lemonnier 1996).…”

Venturi meters are playing an increasingly important role in wet gas metering in natural gas and oil industries. Due to the effect of liquid in a wet gas, the differential pressure over the converging section of a Venturi meter is higher than that when a pure gas flows through with the same flow rate. This phenomenon is referred to as over-reading. Thus, a correction for the over-reading is required. Most of the existing wet gas models are more suitable for higher pressure (>2 MPa) than lower pressure (<1 MPa). Much attention has been paid on higher quality (>0.5) than lower quality (<0.5) in recent years. However, conditions of lower pressure and lower quality also widely exist in the gas and oil industries. By comparing the performances of eight existing wet gas models in low-pressure range of 0.26–0.86 MPa and low-quality range of 0.07–0.36 with a vertically mounted Venturi meter of diameter ratio 0.45, de Leeuw's model was proven to perform best. Derived from de Leeuw's model, a modified model with better performance for the low-pressure and low-quality ranges was obtained. Experimental data showed that the root mean square of the relative errors of the over-reading was 2.30%.

“…In this situation we have reference volumetric flow rates for each of the individual streams of oil, water and gas and, knowing their densities at measured pressure and temperature, the reference total mass flow rate may be calculated from: (5) Having the average reference mass flow rate, M -, and the measured value of ρ∆P from the venturi meter enables calculation of the discharge coefficient from: (6) where A min = π d 2 /4 is the venturi throat area and β is the ratio of throat diameter, d, to full pipe diameter, D, which will be specific to each venturi meter tested.…”
