The measurement of fluid flow rate is important in many industrial applications like rocket propellant, petroleum industry, hydroelectricity station, water meter. Orifice, venturies meter, nozzles, venturi cones, venturi nozzles, drag plates are traditional flow rate measuring instruments. But, The V-Cone throttle device has been paid more and more attentions on the measurement of the wet gas flow in recent years. V-Cone flow meter has varies advantages over conventional flow meter. Finding out V-Cone Meter characteristics for measuring water flow rate is scope of this dissertation. In this research, beta ratio is considered between 0.55 to 0.85. By using volumetric flow equation, maximum diameter of V-Cone Meter is calculated for 102 mm diameter of pipe. Computational fluid dynamics (CFD) is used to simulate the flow in V-Cone Meter. Front angle and back angle of V-Cone Meter is optimized in ANSYS Fluent. Experimentation is held for different flow rate for finding flow rate constant (Cd). 0.75 is optimized beta ratio for flow rate between 125 m3/hr to 60 m3/hr. experimentally flow rate constant is fluctuating between 0.8 to 0.87 for this V-Cone Meter. Experiments are carried out to validate the CFD predictions. This research is concluded that V-Cone Meter can also use for measuring water flow rate.
