There is disclosed a sensor system for determining a fluid level comprising a first sensor comprising a contact sensor a second sensor comprising a conductive sensor and a transducer configured to determine a water level based upon pressure placed on the transducer. There is also a microprocessor in communication with the first sensor, the second sensor and the transducer, the microprocessor configured to determine from at least one of the first sensor, the second sensor and the transducer, a fluid level in a container. In one embodiment the system further comprises a memory configured to feed values to the microprocessor, wherein the values comprise at least one of a high level fluid value and a low level fluid value. In one embodiment the microprocessor is configured to read pressure levels from the transducer wherein the pressure level of the transducer is configured to estimate a fluid level in a container.

Method and system for determining the real-time flow into a wastewater pump station using analog level sensing technologies. An Accurate Level Generator mechanism supplies an accurate mean value out of multiple readings for each level used to calculate the volume between levels. Two consecutive levels are used to calculate the volume between them using an Accurate Flow Calculator and the time it took to get from one level to the other. A Real Time Inflow Calculator adds results regarding the pumps in operation and overflow events, which are ways for the water to exit the pumping station. At a water level approaching where the pumps start or stop, or when abnormal events occur, a Predictive Abnormal Event Adjuster replaces the highly probable abnormal Real Time Inflow Result by a more stable and possible value, which is the last one calculated plus its variation over time.

A water detection system for a fluid storage system includes a housing configured to be disposed in fluid communication with a fluid storage vessel, a water-activated battery disposed within the housing and configured to produce an electrical voltage upon contact with water, and an electronic circuit disposed within the housing and configured to detect water above a threshold within the fluid storage vessel based at least in part on the electrical voltage.

A vehicle fluid reservoir system has a fluid tank that contains a vehicle fluid and a light source in an interior of the fluid tank that illuminates the interior of the tank and the surface of fluid in the tank. The illumination of the surface of fluid in the tank is visible from outside the tank, enabling a quick and easy determination of the level of fluid inside the tank. A switch is operatively communicated with the light source. The switch is operable to control the light source to emit light and illuminate the interior of the tank and the fluid surface in the interior of the tank, and to control the light source not to emit light.
