It also allows for relatively rapid monitoring of large systems: At present, the 3 mph top speed of the device is imposed by the propulsion motors, not the detector itself, so faster surveying is possible. All of these systems could benefit significantly from improved leak-detection methods, Chatzigeorgiou says.
