Abstract
A vessel such as a dairy pasteuriser having a path B for product and a separate path A for coolant in intimate relationship is tested for leaks by circulating a donor fluid under pressure in path A whilst a recipient fluid such as clean tap water is circulated in path B. The donor fluid is a gas, and leakage is detected using an ultrasound probe.
