High liquid alarm system
First Claim
1. A water pump system with high liquid alarms, said water pump system comprising:
- a submersible pump configured for installation inside an enclosed space to remove water accumulated inside the enclosed space to outside the enclosed space;
a pump controller configured to activate the submersible pump when water is detected at a second level inside the enclosed space and to deactivate the submersible pump when water is not detected at a first level inside the enclosed space, wherein the second level is higher than the first level;
a set of alarm sensors configured for mounting at a third level inside the enclosed space, wherein the set of alarm sensors comprises an optical sensor and a capacitance sensor, the optical sensor is configured to detect liquid at a predetermined level above the second level and to enable flow of electrical power to the capacitance sensor when liquid is detected at the predetermined level, and the capacitance sensor is configured to operate intermittently to detect non-conductive liquid at or above the predetermined level; and
a plurality of alarm indicators comprising at least a first alarm indicator and a second alarm indicator, wherein the first alarm indicator is triggered by an output of the capacitance sensor and the second alarm indicator is triggered by an output of the optical sensor.

Abstract
A high liquid alarm system for use in detecting the presence of water and oil in water present in a confined space is disclosed. In one implementation, the system includes an optical sensor capable of detecting water at a certain level, a sensing device capable of differentiating oil and water, and an alarm indicator. The sensors are in communication with an indicator which is capable of providing alert signals. The optical sensor is configured to activate a second alarm in the indicator when water is detected at about a predetermined level and the sensing device is configured to trigger a first alarm when oil in water is detected at about the predetermined level. The sensors can also be interconnected such that the sensing device is activated upon detection of water by the optical sensor, reducing the power consumption of the system.
