pond-friendly sensor float
otterbuoy® provides a safe and efficient means of mounting and accessing sensors in wastewater treatment ponds with side slopes.
otterbuoy® features a 6.5m swing-arm designed to extend into the pond and therefore reach out to deeper water. The swing-arm is positioned using two stability cables.
otterbuoy® incorporates a trolley base with three wheels orientated to match the arc scribed by the swing-arm when traversing up or down the side slope. The two stability cables double as draws lines for launch and retrieval.
Deployment
otterbuoy® is designed to swivel towards the berm, in a clockwise or counterclockwise direction, using the stability cables as draw lines.
The 6.5m fully articulated swing-arm bollard connection allows for any side slope angle.
The three wheels on the trolley base are orientated such that the centreline of each wheel is on an arc determined by the length of the swing-arm.
The trolley design allows off-water launch and retrieval as well as no requirement for lifting gear.
