A liquid level sensing device for sensing liquid in a container. The liquid level sensing device has a base and a rotatable member which extends from and is rotatable relative to the base. A cord extends from the rotatable member and has a sensor provided at a free end thereof. The sensor may be accurately positioned at various heights relative to a bottom of the container to allow a user to fill the container with the liquid to the desired level. An alarm and a signal transmitter are provided in electrical communication with the sensor, such that as a liquid is introduced to the container, the alarm and the signal transmitter will be activated when the level of the liquid reaches the sensor. |
