Abstract

Abstract Diagnostic ultrasound is a powerful tool for characterising a wide range of solutions, with devices such as the continuous wave Malvern Ultrasizer at the forefront. However to reduce capital cost and allow online application without reducing accuracy and application a new system was designed, built and made operational. The ultrafood system is a variable path length pulse system, which produces both time and frequency domain data that is repeatable and accurate compared to reference methods and values. The use of multiple distance measurement removes the need for reference fluid calibration and thermal expansion compensation.
