Devices, systems and methods for leak detection are provided herein. Also provided are devices, systems and methods for monitoring and/or measuring fluid usage. In some aspects, a system comprising a sensor, a processing system, and a platform are provided. In some aspects, the sensor may be coupled to a spinning device. The sensor can be configured to detect fluid data, which can comprise, for example, displacement data of liquid and/or movement data associated with the liquid in a container and/or flow data associated with a flow of fluid in a conduit. The processing system can be coupled with the sensor and configured to communicate the fluid data. The platform can comprise an application communicatively coupled to one or more databases storing evaluation data (e.g., known pattern data) and configured to receive the fluid data and determine if there is a leak.

The present invention relates to methods and systems for implementing a self-test for sump system components using two-way communications between a main controller and each of the system components to check system operation and status. The self-test system is designed to remotely or locally test the installation of field wiring, system functionality and performance of equipment located in an elevator pit, a transformer vault, a transformer moat, a confined space or any other pit/ditch/sump. The benefits of this technology are: 1) ensure proper installation, 2) exercise the system that might otherwise be dormant for years, 3) avoid the costs and risks associated with entering a confined space, and 4) create an easy to implement preventative maintenance program.

Methods and systems are provided for the integration of a fuel level sensor and a fuel pressure sensor in a fuel tank within a fuel system. In one example, an integrated fuel pressure and fuel level sensor for a fuel tank may include a float arm of the fuel sensor coupled to a floating body and a pressure sensor (e.g., a fuel tank pressure transducer) coupled to the floating body, the integrated fuel pressure and fuel level sensor adapted to simultaneously measure fuel level and fuel vapor pressure of the fuel tank.

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 system and method detection of an empty keg is provided. Carbonated beverages from a keg communicates a carbonated alcoholic beverage to a Foam on Beer (FOB) detector. The FOB forms a reservoir and containing a float. Level detection sensors in operative communication with the float identifies the position and movement of the float. An keg's status can thereby be anticipated by float level and speed changes. A the FOB status can thereby operate a touchless tap including a control valve via a tap control board (TCB) that actuates the control valve. A controller in operative communication with the TCB communicates with the control valve, the actuation button and in communication with the level sensor.

A boat trailer depth indicator module and method of installation thereof. The boat trailer depth indicator allows a driver towing a boat trailer to position the boat trailer at an appropriate depth in the water on a boat ramp to launch or recover a boat without the need for an assistant. When the boat trailer is located at an appropriate depth in the water, the boat trailer depth indicator provides a signal to the driver. The signal communicates to the driver and/or the helmsman of the boat, for example, that the boat trailer is sufficiently submerged and ready for launch or recovery of the boat. The boat trailer depth indicator module is independent of vehicle or trailer power and can be installed and adjusted quickly without the use of tools.
