Analysis and Comparison of Performance of Different Orifice Plates in Fluid Flow Measurement Using MATLAB

Accurate measurement of fluid flow is of paramount importance in process industries such as oil, gas, petrochemical, and power plants. Orifice plates are widely used due to their simple design, low cost, and reliable performance. This study presents an analysis and comparison of three common types of orifice plates: Concentric, Eccentric, and Segmental based on discharge coefficient (Ca), pressure drop (AP), and permanent pressure loss. Analytical models were developed in MATLAB to examine the variations of Ca and AP over different flow rates (Q). The results indicate that concentric orifices provide more stable performance for single-phase and clean fluids, while eccentric and segmental orifices are more suitable for fluids containing suspended particles or two-phase flows.
