This paper contains in modelling of twin S-shape coriolis mass flow sensor in Titanium tube and then performing the simulation to determine the optimum phase-shift. To measure the mass flow rate coriolis mass flow sensor is placed inside the tube. The phase shift appears due to the twist in the structure as a result of interactions between the vibration and fluid flow. The phase shift calculated at different sensor positions is helpful in calibrating the accurate mass flow rate and to the
