The flow meter system (100) includes flow meters (110, 120, 140) taking measurements based on a set of parameters of a multiphase fluid (102), each measurement corresponding to respective groups of interrelated unknown variables. These unknown variables are selected from the set of parameters, and the groups of unknown variables are different from each other. A processor uses an iterative process to solve equations of a mathematical model, determined by the equations corresponding to the measurements and groups of unknown variables, so as to estimate an amount of a target unknown variable selected from the set of parameters. The method for estimating a target unknown variable of a multiphase fluid (102) includes installing flow meters (110, 120, 140) in the multiphase fluid (102); taking measurements based on a set of parameters; determining a mathematical model with equations corresponding to the measurements and groups of interrelated unknown variables; and solving equations with an iterative process. |
