    摘要: A liquid level sensing device comprises a housing enclosing a source of electrical energy and an alarm means for providing a warning signal when connected to the source of electrical energy. The device further comprises a sensing probe that has a pair of separated, electrical terminals adapted to be electrically connected when the terminals are immersed in an electrically conductive fluid. The electrical terminals are connected to the alarm means and the source of electrical energy such that the alarm means is activated when the terminals are immersed in the fluid. In the preferred embodiment of the invention the sensor is in the form of a probe adapted to be inserted into conduits disposed below the basement level of a building such that the sensing device is adapted to sense the level of water within the drain system and/or sump pump system of the building so as to provide a warning that a flooding condition in the basement exists prior to flooding.
