dc.description.abstract	This work presents a real-time ultrasonic inspection system with temperature compensation for monitoring oil content in emulsion production lines across food, pharmaceutical, cosmetic and oil refining industries. The system enables continuous, non-destructive quality control by measuring ultrasonic wave propagation velocity through oil-in-water (O/W) emulsions. A specialized measurement chamber with submersible piezoelectric transducers and automated signal processing algorithms provides accurate concentration estimates within 2% error of actual values. Experimental validation with almond oil emulsions demonstrates a strong linear correlation between propagation velocity and oil concentration, with temperature compensation ensuring reliability under industrial operating conditions. The system’s non-invasive nature and real-time capabilities make it suitable for inline implementation in production lines, offering significant advantages over traditional batch testing methods. Index Terms—inline inspection, ultrasonic monitoring, emulsion production, food processing, pharmaceutical manufacturing, cosmetic production, water recovery
