摘要： A tank and liquid level indicator has first housing that holds a liquid and a second elongated housing in fluid communication with the first elongated housing so that a liquid level in the second housing is approximately equal to the level in the first housing. A float in the second housing cooperates with the circuitry to operate one or more light switches. A light-transmissive cover is disposed over the light source.

摘要： A fluid detector for determining a presence of a fluid within a container, the detector including a sensor assembly with a lens and a sensor element that outputs a first ultrasonic signal in response to an input electrical signal. A generally cylindrical wall extends outwardly from an outer surface of the container and defines a housing with a cylindrical central bore having a base surface. The sensor assembly is coupled to the lens so that the lens focuses the first ultrasonic signal toward the wall. The sensor assembly is positioned such that it receives a second ultrasonic signal from the wall that results from the first ultrasonic signal. The sensor assembly then generates an output electrical signal corresponding to the second ultrasonic signal.

摘要： A liquid level sensor for use with a container, including a housing with a body defining an interior volume, a switch actuated by an applied magnetic flux field to a closed position, the switch being disposed within the interior volume of the housing, and a float including a body, a first end and a second end opposite the first end. A pivot assembly includes a magnet and couples the housing and the first end of the float such that the float is pivotable about the pivot assembly between a first position and a second position, and a shunt is disposed within the first end of the float body. The shunt is disposed between the magnet and the switch in the first position of the float, thereby shielding the switch from the magnetic flux of the magnet such that the switch is in the open position.

摘要： A transducer for use in a fluid detector for determining a presence of a fluid within a container, the transducer comprising a piezoelectric element that outputs an ultrasonic signal in response to an input electrical signal, characterized in that said transducer further comprises, a lens with an upper portion, a lower portion, and a focal point, the upper portion including a curved surface with convex side. The piezoelectric element is coupled to the upper portion of the lens so that, when the lens is disposed adjacent an outer surface of a wall of the container such that the lens is intermediate the piezoelectric element and the wall, the lens focuses the ultrasonic signal toward the focal point of the lens and on the inner surface of the wall.
