Publication number: 20240127179Abstract: Volume of a fluid, such as gasoline or diesel fuel, in a tank is determined by measuring the pressure of the fluid using a pressure sensor positioned proximate the bottom of the tank. The depth of the fluid in the tank is then calculated by dividing the pressure by the density of the fluid. Fluid volume is then determined mathematically or from charts given the depth as well as the size and shape of the tank. Multiple pressure readings may be taken along or near the bottom of a tank, and an average pressure determined that may be used to calculate measured volume. To maintain accuracy at different altitudes, pressure readings are preferably adjusted for atmospheric pressure using differential pressure sensors or a processor using data indicative of both pressures. Volume changes exceeding a predetermined threshold, or which are not comparable to dispensed fuel, may be flagged and alerts generated.Type: ApplicationFiled: December 12, 2023Publication date: April 18, 2024Applicant: S1 Technologies, Inc.Inventors: David L.

Publication number: 20220028189Abstract: In a method and a corresponding system for identifying a fuel loss event, periodic measurements of a measured volume of fuel stored in a fuel tank (mobile or stationary) are received, and a measurement of a dispensed volume of fuel dispensed into the fuel tank is received from a fueling station. A total volume of fuel is determined equal to the sum of the dispensed volume of fuel and the measured volume of fuel last measured prior to receiving from a fueling station. A difference is determined between the total volume and the measured volume of fuel first measured subsequent to determining the total volume. If the difference exceeds a predetermined threshold indicating a fuel loss event, an alert is generated indicating that there is a fuel loss event.Type: ApplicationFiled: August 10, 2021Publication date: January 27, 2022Applicant: S1 Technologies, Inc.Inventors: David L.

Patent number: 11085805Abstract: The measured volume of fuel in a storage tank of a vehicle is determined by positioning a sensor within a storage tank holding the fuel. A processor is also located on the vehicle for receiving data relative to the volume of the fuel in the storage tank, the mileage of the vehicle, and vehicle location, date, and time, for transmitting such data to a remote or centralized server (“RS”). The RS also receives fuel dispensed data from a fuel dispensing station (“FDS”), including location, date/time, and volume of fuel dispensed to the storage tank of the vehicle. The RS then compares the data received from the vehicle processor with the fuel dispensed data to determine whether there are any discrepancies between the dispensed volume of fuel purchased, as indicated in the FDS data, and the measured increase of volume of fuel in the vehicle at the time of dispensing from the FDS.Type: GrantFiled: December 27, 2016Date of Patent: August 10, 2021Assignee: S1 Technologies, Inc.Inventors: David L.

The depth of the fluid is then determined from the pressure and density of the fluid. Fluid volume is then determined mathematically or from charts given the depth as well as the size and shape of a tank. Multiple pressure readings may be taken along the bottom of a tank, and an average pressure determined that may be used to calculate volume. Pressure readings may be taken at different heights to determine fluid density used to calculate volume. Pressure readings may be adjusted for atmospheric pressure. Volume increases or decreases exceeding a respective predetermined threshold may be flagged and alerts generated. Volume calculations may be recorded for comparing against a volume of fluid recorded as being purchased.Type: GrantFiled: October 30, 2014Date of Patent: January 31, 2017Assignee: S1 Technologies, Inc.Inventors: David L.

Patent number: 9528872Abstract: An inventory of a consumable is managed by positioning a sensor within a storage tank holding the consumable and determining the volume of the consumable in the storage tank. A processor is also located on the vehicle for receiving data relative to the volume of the consumable in the storage tank, the mileage of the vehicle, and vehicle location, date, and time, and for transmitting such data to a remote inventory management server (“RIMS”). The RIMS also receives point-of-sale (“POS”) data, including location, date/time, purchase amount, and purchase price related to a consumable intake event at the storage tank of the vehicle. The RIMS then reconciles the data received from the vehicle processor with the POS data to determine whether there are any discrepancies between the fuel purchased and the volume of fuel measured.Type: GrantFiled: October 30, 2014Date of Patent: December 27, 2016Assignee: S1 Technologies, Inc.Inventors: David L.
