This paper presents a laboratory feasibility study aiming at the development of a dual modality sensor for development within an oil and gas extraction plant to measure the composition of heterogeneous mixtures. The technology of manufacturing the sensor is briefly described and the preliminary measurements, conducted for mixtures of vegetable oil and saline water, using two modalities: ultrasound and electrical, are presented. The experimental results obtained from ultrasonic measurements are compared with theoretical predictions. Finally, conclusions and recommendations for future work are presented.
