Abstract:
A liquid level gauge comprising:(a) a gauge head adapted for mounting to a portion of a liquid storing container;(b) a support arm rigidly connected to said gauge head and depending therefrom;(c) a float arm including a unitary structure having elongate inner arm section, an elongate outer arm section and a hinge section;said inner arm section being pivotally connected to said support arm for movement through an arc defining a first plane;said hinge section being connected at a first end to an outer end of said inner arm section and connected at an opposite end to an inner end of said outer arm section;said hinge section being deflectable to allow movement of said outer arm section between a first configuration in which said outer arm section is in a predetermined position with respect to said inner arm section and a second configuration in which said outer arm section is not in said predetermined position with respect to said inner arm section;said hinge section providing a biasing force for urging said outer arm section into said first configuration; and(d) a float connected to an outer end of said outer arm section, said float being buoyant so as to remain at the surface of a liquid.
