An alert system is disclosed providing motorists an alert in advance of flood areas being flooded. The disclosed system provides real-time information on water levels adjacent or on top of roadways. As water levels enter a gauge unit, a signal from the gauge unit is sent to trigger a warning light that motorists or pedestrians can see from the roadway before reaching an area of the roadway that maybe flooded. The embodiments disclosed may prevent loss of life and avoid costly automotive repairs due to water damage.

A float switch assembly for use in actuating a switch to operate a pump to control the level of a fluid in a tank. A float switch assembly for operating a pump to control the level of a fluid in a tank based in part on the angle of the float switch caused by the varying fluid level. A system for controlling a level of a fluid in a tank, the system including a pump fluidly coupled to the tank and configured to pump the fluid from the tank to lower the level of the fluid in the tank.

A magnetic float switch is provided. The magnetic float switch can include a housing configured to float in a liquid, response circuitry located inside the housing, an internal chamber located inside the housing, a float state indicator housed within the internal chamber, and an actuating arm housed outside the internal chamber and coupled to the response circuitry. In operation, when a position of the housing changes so as to indicate an increasing level of the liquid, the float state indicator can move within the internal chamber from a first position to a second position to initiate a magnetic force between the float state indicator and the actuating arm so as to actuate the actuating arm from an inactive position to an active position. Then, when the actuating arm is in the active position, the response circuitry can initiate a response to the increasing level of the liquid.

A flood warning system has a gauge unit adapted to be positioned adjacent to a waterway and a display adapted to be positioned away from the waterway and adjacent to a roadway. The gauge unit has a plurality of sensors arranged in vertically-spaced relation within a housing of the gauge unit. The housing has a fluid inlet adapted to allow water to enter the housing when a level of water in the waterway raises above a low position. The plurality of sensors are adapted to detect a level of water within the housing of the gauge unit. The display has a warning indicator thereon. The display is cooperative with the gauge unit such that the warning indicator is actuated when the level of water in the housing of the gauge unit is above one of the plurality of sensors.

A flood warning system for providing persons with an advance warning of a flooded area has a gauge unit positioned in a waterway, a control unit configured to receive signals transmitted by the gauge unit in order to determine whether a condition of the waterway is safe, and a warning light unit positioned remotely from the gauge unit in a path adjacent to a roadway ahead of the waterway. The gauge unit has one or more sensors in a housing that measure a water level is water enters or exits the housing and a signal transmitter cooperative with the gauge unit that transmits a signal in response to a pre-defined water level being reached. The warning light includes a light illuminated in response to the gauge unit measuring a current water level is flooding the roadway.

The float switch device for submersible pumps, comprises a float member (2) constrained to a flexible cable (3) which is electrically connected to the driving member of the pump (10). The flexible cable (3) is associated with a tilting support member (5), mounted in tilting manner outside the body of the pump (10) on a pin (6) with a substantially horizontal axis. The float member (2) is provided with a switch member (24) electrically connected to said flexible cable (3) and actuatable by actuator means (22) mobile as a function of the liquid level (L1, L2), for controlling the starting and stopping of the pump (10).

The present application generally relates to a sump pump system configured for use in a sump that may contain liquid. In one embodiment, the system includes a sump pump, first and second vertical float switches having respective piggyback end plugs, and a dual connector assembly comprising first and second electrical connectors. Male connection points of each of the vertical float switch end plugs are plugged into respective female connection points of the first electrical connector, which terminates at a single male connection point plugged into an AC power source. The second electrical connector has a single female connection point and terminates at two male connection points. The sump pump is plugged into the single female connection point of the second electrical connector, and the two male connection points of the second electrical connector are plugged into the respective female connection points of the two piggyback end plugs.

A method of manufacturing a float switch assembly for use in actuating a switch to operate a pump to control the level of a fluid in a tank. A method of manufacturing a float switch may include placing two halves of a float switch housing such that contact is made along a relatively flat surface area of the two halves, and moving the two halves in a vibratory manner relative to each other in a direction generally parallel to the relatively flat surface area.
