First Report

Power Ultrasound by Altum Technologies

Altum’s approach is to use externally-mounted – to a pipe or tank – ultrasound-generating piezoelectric transducers, focused at a particular target point in the container for the best cleaning effect. The transducers produce an oscillating sound wave into the liquid stream, making air bubbles with increasing diameters. When the cavitation threshold is exceeded, the bubbles collapse, producing high-force shockwaves onto the inner surface of a container, displacing the fouling deposited there...

Daisy Robot by Pipeguard Robotics

Sensors are housed in the ring of “fins” of the robot – which resembles a shuttlecock – and as the robot flows passively through the water, the sensors come into contact with the pipe wall. If a leak exists, it will produce a suction force pulling on the fins of the robot. As the suction sensors stretch from the counterforce exerted by the flow of the water pushing it forward, the magnitude of the leak can be measured.

Daisy currently comes in sizes to suit three different diameters of pipe: 50mm, 100mm and 150mm...
