Liquid level gauge for pressurized tanks

A liquid level gauge for determining the level or volume of liquid within a tank, the liquid level gauge comprising:

• 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 adapted to extend into the tank from the mounting head for detecting the level or volume of liquid within the tank;
• wherein the gauge assembly comprises:
• a gauge plate with a scale located thereon for indicating level or volume of liquid within the tank;
• the gauge plate being rotatable about a first axis and having a weighted portion such that the gauge plate naturally rotates toward a gravitational force vector to follow a horizontal orientation of an upper surface of the liquid in the tank;
• an indicator located adjacent to the scale for indicating level or volume of liquid in the tank, the indicator being rotatable about a second axis and operably connected to the elongate sensing probe, with an amount of angular rotation of the indicator being dependent on a change in the level or volume of liquid in the tank;
• wherein the gauge plate and indicator rotate independently of each other to indicate liquid level or volume within the tank independent of tank tilt or orientation, and skewed installation of the gauge assembly.
