This is a continuation-in-part of U. This invention relates to gauges for measuring the level of liquid in a tank. In one aspect, it relates to a float-type liquid level gauge for measuring the level of liquid in a tank containing a liquefied petroleum gas. Liquids of the liquefied petroleum gas type, such as propane, butane, and the like often referred to generally as LPGare commonly used for purposes such as residential or industrial heating, or for powering internal combustion engines on industrial vehicles such as lift trucks i.
The LPG is typically stored as a liquid under pressure in a tank or cylinder. A liquid level gauge may be provided on the tank for measuring the level of the liquid in the tank. In some applications such as lift trucks, the LPG cylinders are oriented horizontally while in use on the vehicle but are stored vertically when removed for refueling. In such applications, a liquid level gauge which can measure liquid levels in both orientations is desirable.
In many regions, the dimensions of LPG tanks used in these stationary applications have become standardized in the form of cylinders having a diameter measured perpendicular to their elongate axis of 24 inches, 30 inches, In other regions, tank sizes approximating the standard sizes are used having a range of diameters from about 24 inches to about 42 inches.
The tanks are usually installed on their side with their elongate axis horizontal. It is, of course, desirable to have a liquid level gauge which can indicate the level of LPG within such a stationary tank. In the case of a stationary tank, however, there is no need for the liquid level gauge to indicate the LPG level when the tank is in more than one orientation, as in the case of gauges for use with lift-truck cylinders.
Instead, in the case of a stationary cylinder, it is desirable that the liquid level gauge accurately measure the level of LPG within the tank, especially when the LPG level is low, i. Further, it is desirable that the measured level of LPG be indicated with high angular resolution on the gauge dial.
Accurate low level measurements are especially important to help the user avoid running out of LPG, while accurate high level measurements are especially important to help the user determine the level of LPG in a near-full tank.
A high resolution indication of the measurement, i. Liquid level gauges for measuring the level of a liquid such as LPG inside a tank are disclosed in U. These patents disclose float-type liquid level gauges that utilize a pivoting float arm having a position which is responsive to the liquid level inside the tank. The float arm is connected to a rotatable shaft by means of a geared mechanism, and the shaft is magnetically coupled to an external liquid level indicator.
A change in liquid level causes the float arm to rotate the shaft, and the magnetic coupling then rotates the external indicator without requiring a direct physical connection. Thus, the possibility of volatile liquid or vapor leaking through the mechanism is eliminated. While useful, the previously disclosed float-type gauges have several drawbacks.
First, due to the low density of LPG, the heavy-walled hollow float used to resist the pressure in the tank has insufficient buoyancy to float without a counterweight to balance the float arm. Such counterweights are typically discrete components which add to the manufacture and assembly expense of the gauge, and their size often increases the difficulty in installing the gauge through the narrow opening of the tank or cylinder.
