Abstract
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.
Claims21
A method for identifying a fuel loss event, the method comprising steps of:
- receiving, from at least one fuel tank, first data signals indicative of periodic measurements of a measured volume of fuel stored in the at least one fuel tank;
- receiving a second data signal indicative of a measurement of a dispensed volume of fuel dispensed into the at least one fuel tank;
- determining a total volume of fuel equal to the sum of the dispensed volume of fuel and the measured volume of fuel last measured prior to the step of receiving the second data signal;
- determining a difference between the total volume of fuel and the measured volume of fuel first measured subsequent to the step of determining the total volume of fuel;
- determining if the difference exceeds a predetermined threshold indicating a fuel loss event;
- and
- generating an alert if it is determined that there is an indication of a fuel loss event.
A method for identifying a fuel loss event, the method comprising steps of:
- receiving, from at least one fuel tank, first data signals indicative of periodic measurements of a measured volume of fuel stored in the at least one fuel tank, wherein each periodic measurement includes a first date/time stamp indication of when a respective periodic measurement was made;
- receiving second data signals indicative of a measurement of a dispensed volume of fuel dispensed into the at least one fuel tank, wherein a second date/time stamp is associated with the start of dispensing fuel to the at least one fuel tank, and a third date/time stamp is associated with the end of dispensing fuel to the at least one fuel tank;
- determining a total volume of fuel equal to the sum of the dispensed volume of fuel and the periodic measurement having the latest first date/time stamp prior to the second date/time stamp;
- determining a difference between the total volume of fuel and the periodic measurement having the earliest first date/time stamp subsequent to the third date/time stamp;
- determining if the difference exceeds a predetermined threshold indicating a fuel loss event;
- and
- generating an alert if it is determined that there is an indication of a fuel loss event.
A system for identifying a fuel loss event, the system comprising:
- a first data signal receiving circuitry operable to receive, from at least one fuel tank, first data signals indicative of periodic measurements of a measured volume of fuel stored in the at least one fuel tank;
- a second data signal receiving circuitry operable to receive a second data signal indicative of a measurement of a dispensed volume of fuel dispensed into the at least one fuel tank;
- a first logic circuitry operable to determine a total volume of fuel equal to the sum of the dispensed volume of fuel and the measured volume of fuel last measured prior to receipt of the second data signal;
- a second logic circuitry operable to determine a difference between the total volume of fuel and the measured volume of fuel first measured subsequent to receipt of the second data signal;
- a third logic circuitry operable to determine if the difference exceeds a predetermined threshold indicating a fuel loss event;
- and
- a fourth logic circuitry operable to generate an alert if it is determined that there is an indication of a fuel loss event.
