Abstract
A liquid regulator device has a buoyant body which is anchored to a side of the vessel by an electrical conductor. The body contains a movable ballast in the form of a ball and an attitude sensitive switch connected to the electrical conductor. The buoyant body floats in the liquid with one end in the uppermost position. Changing the liquid level tensions the electrical conductor causing the body to tumble. When the body has tumbled through a predetermined angle, the ballast moves from one end of the body to the other to cause the body to rapidly assume the reverse orientation. This causes the attitude sensitive switch to change state, which is used to control the liquid level.
