Abstract
A float activated gauge for indicating the level of liquid in a tank utilizes a twisted float following member. The float following member is disposed adjacent to the float and is caused to rotate as the float moves vertically due to a change of the level of liquid in the tank. A U-shaped main body for the gauge guides the float vertically, holding the float captive and against the float following member. A needle extends at a right angle from the float following member and is externally visible to provide an indication of the amount of rotation of the float following member and, therefore, the level of liquid in the tank.
