Warning Float / Covers

Warning Float
Warning Float

Warning float is a kind of temporary warning device which is concealed on the inner wall of drains. When the rainstorm comes, if the manhole covers are displaced or get lost, water will diffuse into the drains, and then the warning float would start to float onto the water level above the wellhead of drains. The red light on the floats will automatically remind pedestrians and vehicles to detour and avoid getting into risk, which action would protect the personal safety effectively.
