    摘要： In a fuel tank level sensor 1 for measuring a remaining amount of fuel in accordance with a resistance value which is varied by moving a rheostat 1a utilizing a float 1c that vertically moves according to increase and decrease of the fuel in a fuel tank 2, change in resistance value of the rheostat 1a includes a linear range in which the resistance value linearly varies with the increase and decrease of the fuel, and a non-linear range in which the resistance value discontinuously varies under full-tank conditions where the fuel tank is substantially filled up with the fuel. Even upon undesirable increase of the resistance value of the rheostat 1a as a result of deposition of sulfides, the sensor 1 can always detect accurately that the fuel tank 2 is filled up.

    摘要： The alarm mechanism of the invention signals the absence of a liquid from a source of aqueous liquid. The alarm mechanism comprises an alarm body having an inlet port and an outlet port; the inlet port in liquid communication with a source of liquid, the outlet port in liquid communication with a use locus. The alarm mechanism additionally comprises a float chamber placed in liquid parallel communication with the inlet port and the outlet port. The float chamber contains a float operably connected to a mechanical alarm. The float, as the chamber is emptied of liquid, reaches a position wherein a "low or empty product" signal is generated. The apparatus operates by passing liquid through the body. As liquid in the source of liquid is depleted and is no longer available for passage through the body, the body becomes emptied of liquid as the source of pressure removes liquid from the body and particularly from the chamber causing the float to reach a position generating a signal.

    摘要翻译： 本发明的报警机构通知来自水性液体的液体不存在。 报警机构包括具有入口和出口的报警主体; 入口与液体源液体连通，出口与液体相通，使用轨迹。 报警装置还包括浮置室，其与进口和出口端口平行地配置成液体。 浮子室包含可操作地连接到机械报警器的浮子。 当腔室排出液体时，浮子达到产生“低或空产品”信号的位置。 该装置通过使液体通过本体进行操作。 当液体源中的液体耗尽并且不再可用于通过身体时，由于压力源从体内特别是从腔室移除液体使得浮子达到产生位置的位置，所以身体被排空了液体 信号。

    摘要： A liquid level sensor apparatus and a method of using thereof for determining the level of a conductive liquid held within a container, wherein the container is subject to the accumulation of residue as a consequence of the conductive liquid contained therein. The liquid level sensor includes a sensor part which has a voltage; a ground connection having an electrical polarity; a circumferential ring having a bias voltage opposite in polarity to the ground connection and a voltage corresponding to that of the sensor attached around the sensor; a float which is buoyant on the conductive liquid; and a conductive tip attached to the top of the float, the conductive tip being conductive with the sensor end when in at least one predetermined position.
