摘要： A gauge assembly for measuring the level of a liquid product in a storage tank includes a float member that is constructed and arranged to float on the liquid product in the storage tank, a housing that is constructed and arranged to be mounted on an exterior of the storage tank and a drum that is mounted inside the housing for rotation about an axis. A filament is wound about the drum, and extends through an opening defined in the housing to an attachment with a float member. A spring is provided for biasing the drum in a first rotary direction that will wind the filament onto the drum, whereby the drum will tend to pull the float member toward the housing, keeping the filament taut. A clock-type face is mounted on the housing, and has distance indicia marked there around that is in a base-twelve numbering system to represent feet and inches, rather than hours and minutes. A small hand is mounted to traverse the clock face to represent feet, and is connected to the drum via a gear train. A large hand is mounted to traverse the clock face to represent inches, and is also connected to the gear train. A novel alarm system for indicating when the storage tank is filled to a predetermined maximum level includes an alarm indicator mounted on the clock face to indicate a level of the float member at which the alarm will sound. The alarm indicator is ordinarily connected to the gear train, but may be adjusted with respect to the gear train, whereby a user will be able to manually adjust the level at which the alarm system will be actuated to correspond to a selected level in the storage tank.

摘要翻译： 用于测量储罐中的液体产品的液位的量规组件包括构造和布置成浮在储罐中的液体产品上的浮子构件，构造和布置成安装在储存罐的外部上的壳体 储罐和安装在壳体内部以围绕轴线旋转的鼓。 细丝缠绕在滚筒周围，并且通过壳体中限定的开口延伸到具有浮子部件的附件。 提供弹簧以沿着将灯丝卷绕到滚筒上的第一旋转方向偏压滚筒，由此滚筒将倾向于将浮子部件拉向壳体，从而保持丝束紧紧。 时钟型面安装在外壳上，并在其周围标记有距离标记，该标记位于十二位编号系统中，以表示英尺和英寸，而不是几小时和几分钟。 安装一只小手穿过钟表以表示脚，并通过齿轮系连接到滚筒。 安装一只大手穿过钟表以表示英寸，并且还连接到齿轮系。 用于指示储罐何时被填充到预定最大水平的新颖的报警系统包括安装在时钟面上的报警指示器，以指示警报器将发出声音的浮子部件的水平。 报警指示器通常连接到齿轮系，但是可以相对于齿轮系调节，由此用户将能够手动地调整报警系统将被致动的水平以对应于存储器中的选定水平 坦克。
