Patent attributes
A liquid level gauge for determining the level or volume of liquid within a tank includes a mounting head adapted for connection to the tank, a gauge assembly connected to one side of the mounting head, and an elongate sensing probe assembly extending into the tank. The gauge assembly includes a rotatable gauge plate with a scale located thereon and a rotatable indicator that moves across the scale in response to a change in liquid level. The gauge plate is weighted for rotation toward a gravitational force vector for orientation with an upper surface of the liquid in the tank independent of tank tilt. The sensing probe includes a float rod with an integral coil spring hinge to facilitate installation of the gauge within the tank. A counterweight is adjustable along the float rod to fine-tune float weight or buoyancy for a particular gauge configuration and liquid type.
