Infrastructure Insider: Online viscosity monitoring for consistent asphalt quality
Viscosity is a key indicator for asphalt properties and quality. In this webinar we will describe the advantages of vibrational sensors for inline monitoring of asphalt and asphalt emulsion viscosity. We will describe a ruggedized torsional inline viscometer that has been successfully integrated into a network of asphalt terminals. A key requirement for inline viscosity measurement, particularly in remote, less-accessible locations, is long-term stability and freedom from maintenance. The unique technology behind the sensor makes it both easy to clean and free from periodic calibration.

In the webinar, we will discuss the underlying technology of the viscometer, including those features that make it particularly robust and independent of installation position and orientation. We will also discuss the particular demands of asphalt applications, including measures that need to be taken during shutdown and startup of asphalt lines. An important requirement for remote monitoring of viscosity is the interface over which the viscosity data is transmitted. We will summarize the available electronic interfaces and how they contribute to making the system compatible with existing monitoring and logging equipment.

Dr. Sunil Kumar
Chief Executive Officer @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.
