Design and Simulation of Electro-Mechanical Mass Flow Sensor (EMMFS)

Abstract

The main objective of this chapter is FEA simulation of resonating tube with different size and material configuration for evaluation of resonant frequency. Resonating tube is an important component of Electro-Mechanical Mass Flow Sensor (EMMFS) used for measuring direct mass flow. Omega and U-shaped resonating tube type EMMFS have been investigated for 200mm, 300 mm and 400mm height with three different materials Copper, Aluminium and Mild Steel. EMMFS analysis is highly nonlinear study having fluid structure interaction. To simplify the solution large deformations in resonating tube countered to be absent. Sensing points are located symmetrically at limbs of resonating tube to sense the phase shift for measuring mass flow rate. FEA simulation of EMMFS has been done using Ansys. Solid Edge and Pro-E has been used for modeling of omega and U-shaped resonating tube.
