A novel two-phased flow meter design using MEMS pressure meters array

Abstract

Nowadays, processes which contain interacting liquid and gas phases are very common. For this reason this type of fluids have an important role in technology-based applications. So further and through investigations and an application-oriented knowledge desperately needed. Determining two-phased fluid flow is one of most challenging concepts dealing with these fluids. Common methods for measuring mentioned flows is Coriolis flow meters or by separating phases and determining each phase flow separately. One of important weaknesses in Coriolis flow meters is accumulation of gases inside them that causes malfunctioning. Also these methods have defects such as delay in measuring and lack of sufficient accuracy. The proposed method in this paper consist of simulating implementation of an array of MEMS pressure meters at the cross section of a tube carrying two phase flow. Some structural information of tube and MEMS pressure sensors data can be used for numerical analysis which ultimately estimates flow rate of fluid. The proposed method has advantages such as less delay, easy implementation, no need for peripheral accessories and less computational efforts rather than available industrial procedures.
