Precise control of ceramic slurry viscosity and density is essential to maintain consistent shell quality in investment casting. Traditional methods, such as efflux cups and lab density meters, require constant operator attention and manual intervention.
Rheonics and Nalco Water (an Ecolab company) present a fully automated approach using the SlurrySense with CleanWave™ self-cleaning sensor and 3D TRASAR™ system. This solution provides real-time slurry viscosity and density data, enabling operators to validate manual readings, avoid unnecessary dilution, and reduce labor.

This implementation has significantly improved slurry consistency, reduced operator workload, and enhanced shell quality, highlighting the power of real-time measurements and automation in investment casting.

Dr. Sunil Kumar
CEO @ Rheonics
Sunil Kumar has extensive experience in the sensors and energy sector, having worked in a variety of roles in engineering and research in his early career. Most recently Sunil worked at Baker Hughes where he led global engineering for drilling Services. Sunil founded companies in US and UK that successfully commercialized innovative products. He graduated with Bachelors in Aerospace from Indian Institute of Technology, Kharagpur, Masters in Mechanical engineering from University of California, Irvine and Ph.D in Electrical engineering from Imperial College, London where he developed the Seis-SP seismometer that is part of the main payload for the NASA Insight mission to Mars. He is a prolific inventor with over 25 patents and multiple peer reviewed papers. Sunil’s vision of creating sensors for fluid property measurement that revolutionizes in-line process monitoring, control and optimization serves as the charter for rheonics.
