Patent ID: 8344898

Claim:
A liquid level sensing device for sensing liquid in a container, the liquid level sensor comprising: a housing having a power source and an alarm; a first reference surface positioned on the housing, the first reference surface cooperating with a top surface of a container when the liquid level sensor is initially positioned on the container; a sensor extending from the first reference surface, the sensor being in electrical communication with the alarm, so that as one or more liquids is poured into the container, the alarm will be activated when the level of the liquid reaches the sensor; a positioning member, the positioning member cooperating with the container to provide a reference to allow the liquid level sensing device to be accurately moved from the initial position to other predetermined positions relative to the container; whereby the liquid level sensing device may be accurately positioned at various positions relative to the container using the first reference surface and the positioning member to allow a user to fill the container with one or more liquids to the desired level.
