Abstract  The relation between the meter factor and flow rate for various dual bluff body combinations is investigated.A set of bluff body combination with an optimal performance of linearity and pressure loss is achieved through the pressure loss analysis.The experimental results of meter factor and pressure lOSS are also presented. The results show that the dual bluff body combination can have a similar constant Strouhal number to the single bluff body in the specific range of the flowrate.
