ABSTRACT:
A gauge (10) is disclosed which provides advantages in accuracy and cost. A head (16) is mounted on a reservoir containing a fluid to be monitored. A cylindrical support tube (28) is secured to the head and extends into the fluid. A head bushing (40) and a bottom bushing (42) are secured at opposite ends of the tube (28) and support a helically twisted center shaft (48) for rotation about an axis. The center shaft passes through a float (60) which is guided for movement along the axis by guide ribs (34, 36) on the support tube.
