ABSTRACT:
A device for measuring the thickness of an ice layer comprises a hollow, watertight body formed by two cones joined at their bases. The interior of the device is provided with a medium which acts as a ballast and allows the device to float on the surface of the water. The device is anchored in place by an elastically deformable line secured to a weight such that the device is pushed upwardly by the pressure exerted when an ice layer is formed. The device is provided with indicia on the surface thereof to indicate the thickness of the ice layer being formed.
