A technique for measuring quantity of oil in a flowing water-oil mixture

Often different liquids are mixed to achieve a desired product in process industry. Measurement of liquid quantity which is added is very essential as in appropriate mixture may lead to failure of desired product. The proposed paper makes an attempt to measure the quantity of liquid added when the flow is under dynamic condition. An orifice flow meter is used to measure the flow rate of the mixture. Output of flow meter after conditioning is transmitted to the PC. Using the relation of model parameters and density, density of mixture is calculated. On comparing the densities, amount of liquid added can be determined. The results computed were compared with actual values and is proved that the proposed technique has achieved its set objectives, with a root mean square percentage error of 0.039%.
