“…Stewart et al [25,26] reported that the ε of a V-Cone meter with the constant β is independent of Re and dependent on the DP ( P), the operating pressure (P) and the isentropic exponent (κ). ε has the form given in equation (10). Moreover, studies also show that C d slightly increases with Re with other parameters kept constant [29].…”

“…partial separation, isokinetic sampling, vortex meters and ultrasonic meters) are available to meter the wet gas, the majority of wet gas meter designs employ the differential pressure (DP) meter technology including the orifice plate, the Venturi and V-Cone meter [5]. Many investigators such as Murdock [6], Chisholm [7,8], Smith and Leang [9,10], Lin [11], de Leeuw [12], Steven and Stewart [13][14][15][16] and Dong [17,18] have explored the DP devices in wet gas (in fact, some of their testing conditions were beyond the range of wet gas flow). They found that DPbased flow meters shared many performance characteristics in wet gas applications.…”

Wet gas metering with differential pressure (DP) devices (e.g. the orifice plate, the Venturi and the V-Cone) has gained increasing interest in the oil and gas industry. Many investigations have been performed and several models have been proposed. Among the DP devices, the V-Cone flow meter has received increasing attention owing to its remarkable performance characteristics, including high accuracy, excellent repeatability, wide turndowns, shorter straight length and stable signals. In this work, we developed a new method for predicting the gas flow rate in low pressure wet gas flow using a V-Cone flow meter with the diameter ratio of 0.55. The experimental fluid was air and tap water. The test pressure ranged from 0.10 to 0.48 MPa, and the gas and liquid mass flow rates ranged from 100 to 500 N m3 h−1 and from 0.030 to 0.358 m3 h−1, respectively. Thus, the Lockhart–Martinelli parameter, XLM, was up to 0.158 and the gas volume fraction ranged from 98.94% to 100%. A dimensionless parameter, K, was proposed in this work and defined as the two-phase flow coefficient of the flow meter. The results indicated that the K linearly increased with the Lockhart–Martinelli parameter. In addition, the K increased with the gas densiometric Froude number and decreased with the operating pressure when other parameters were kept constant. On the basis of the two-phase flow coefficient, a new wet gas model was developed and compared with seven popular wet gas models. It was found that with the V-Cone flow meter and under the present experimental conditions the new model produced a more accurate prediction of the wet gas than other models. The research approach to obtaining the model can also be used in the studies on other DP devices and thus will benefit the design of wet gas meters.
