Abstract: The Vibration based mass flow sensors offers unprecedented accuracy, robustness and reliability in measuring materials flow in wide range of applications like process industries over more than 20 years. This measures mass flow directly and is not affected by other factors as compared to conventional volume flow measurement techniques such as the density or viscosity of the fluid, or the profile or Reynolds number of the flow. It is a nonintrusive type of sensor, has no moving parts thus reducing maintenance problems. Despite the successful industrial utilization, the performance of such type of sensors is still not fully understood. Therefore, the primary objective of present work is aimed to develop and calibration of the mass flow sensor prototype. This prototype is designed on Pro Engineer Wildfire modeling software and later developed on the basis of theory of vibrating beams, fluid structure interaction and Coriolis technology in the laboratory. This prototype is calibrated successfully for water giving linear relationship between phase shift and mass flow rate as per the classical relationship found in the published literature for various sensor locations as well as drive frequencies.
