Abstract:

A water sensor includes a housing that has at least one inlet port formed therein for allowing water to pass there through when submerged in water. A drive piston is mounted in the housing for sliding engagement therein. A water-activated driver is coupled to the drive piston and is in communication with the inlet ports. The water-activated driver is inert in air and reactive with water to exert pressure on the drive piston and so that the drive piston moves in the housing. A movable indicator is mounted relative to the housing and is positioned to be responsive to movement of the drive piston. The movable indicator moves from a first position to a second position in response to movement of the drive piston.
