Computational Simulation of the Stainless-Steel Straight-Tube Coriolis Sensor for Mass Flow Measurement

This paper presents a computational simulation of a stainless steel straight-tube Coriolis sensor, focusing on the design and validation of a mathematical model for mass flow measurement. The Finite Element Method (FEM), implemented in GNU Octave, is used to solve the differential equations governing the tube’s vibrational behavior. The simulation determines the angular resonance frequency (723.6 rad/s) and evaluates mass flow for fluid velocities ranging from 0.5 m/s to 25 m/s. The results are validated against reference data from existing literature, demonstrating strong agreement and confirming the accuracy of the proposed model. These findings reinforce the potential of Coriolis sensors for precise and efficient mass flow measurement in industrial applications such as chemical processing and fluid transport monitoring.
