Abstract
Experimental work has been carried out to investigate the use of ultrasound in the detection of slurry ice flows within pipes. The work sets out the basis for a novel device that is both portable and adaptable to retrofitting onto existing pipelines. This method of noninvasive pipeline interrogation has applications within many parts of the chemical and process industries. The work described here relates particularly to the use of ultrasound to detect the presence of an ice pig within product pipelines in the food industry. Research has shown that the products tested and the ice slurry have very different ‘sound signatures’. The signals obtained from ultrasonic tests proved to be reproducible, even under dynamic flow conditions. Contamination of products with slush ice was detectable down to the levels of a few per cent of slush ice. The technique was verified for detection of the interface between the product and the ice pig under flow conditions.
