ADJUSTABLE SENSOR FOR SENSING A LEVEL OF LIQUID
First Claim
1. A liquid level sensing device for sensing liquid in a container, the liquid level sensing device comprising:
- a base;
a rotatable member extending from and rotatable relative to the base;
a cord extending from the rotatable member, the cord having a sensor provided at a free end thereof;
an alarm provided in electrical communication with the sensor, such that as a liquid is introduced to the container, the alarm will be activated when the level of the liquid reaches the sensor;
engagement portion positioned on the rotatable member;
an engagement projection extending from the base, the engagement projection being positioned to engage the engagement portion to allow the cord and the sensor to be accurately positioned relative to the base;
whereby 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.

Abstract
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.

10. A liquid level sensing device for sensing liquid in a container, the liquid level sensing device comprising:
-
a base; a rotatable member extending from and rotatable relative to the base; a cord extending from the rotatable member, the cord having a sensor provided at a free end thereof; a signal transmitter is provided in the liquid level sensing device and is in electrical communication with the sensor, such that as a liquid is introduced to the container, the signal transmitter will be activated when the level of the liquid reaches the sensor and will communicate the same to a respective signal receiver positioned remote from the signal transmitter; engagement portion positioned on the rotatable member; an engagement projection extending from the base, the engagement projection being positioned to engage the engagement portion to allow the cord and the sensor to b accurately positioned relative to the base; whereby 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. - View Dependent Claims (12, 14, 16)
