Abstract
A float activated gauge includes a float, a frame for guiding the vertical movement of the float, and a twisted metal strip coacting with the float to provide a visual indication of the vertical position of the float. The frame is held in position by an easily assembled head comprising a ring body and a cap. The frame comprises two vertical rods, each of which terminates on its upper end in an outwardly extending stub. When assembled, the rods and stubs of the frame are sandwiched between the cap and the ring body, so that assembly of the gauge does not require bending or deforming of the frame.
