Abstract
Embodiments of the present disclosure relate generally to a liquid level sensor system that allows ease of connection and disconnection of a removable vessel (such as a toilet bowl) from a stationary unit (such as a toilet frame). The system provides at least one liquid level sensor (a first part of the sensor probe connection) mounted to the removable vessel, a liquid level sensor circuit board mounted to the unit, and a connection feature (a second part of a sensor probe connection) configured to extend between the sensor and the circuit board. When the removable vessel is removed from the vessel, the sensor probe connection is disconnected without the need for manual intervention. Installation of multiple probes and varying their location can support detection of a single or several discrete levels, or provide for any required redundancy of detection.
