A fuel dispensing terminal comprises a memory and a processor. The memory is configured to store fuel inventory data that indicates levels of fuel in a fuel tank during a time period. The processor is operably coupled to the memory and configured to determine an actual amount of fuel that left the fuel tank based at least in part upon the fuel inventory data, determine a calculated amount of dispensed fuel associated with one or more fuel dispensing operations during the time period, and compare the actual amount of fuel that left the fuel tank with the calculated amount of dispensed fuel. The processor is further configured to determine that the actual amount of fuel that left the fuel tank is more than the calculated amount of dispensed fuel, conclude that at least one fuel dispensing operation is anomalous, and cause the fuel dispensing terminal to stop dispensing fuel.

A fuel dispensing terminal includes a memory that stores a threshold volume per unit time and a threshold wait period, and a processor operably coupled to the memory. During fuel dispensing, the processor periodically determines the cost-based volume of fuel dispensed and calculates a measured volume per unit time by dividing this value by the fuel cost per unit volume. The processor compares this measured rate to the stored threshold. If the measured volume per unit time falls below the threshold within the specified wait period, the terminal automatically stops dispensing fuel.

An improved fluid transfer accuracy, information collection, and overall management. A system may utilize a pump to transfer fluid from a source to a target vessel, a meter for measuring an amount of fluid transferred, a density meter to detect actual fluid density, and a control unit to determine actual fluid transfer amount based on density. As an example, a fluid flow meter can be coupled with a flow conduit to determine fluid volume, along with the density meter to detect real-time density of transferred fluid. During a fluid transfer event, such as aircraft refueling, LPG fueling, or other refined fuels or valuable liquids, fluid volume can be converted to fluid weight in real-time based on actual density. The real-time fluid weight can be used to determine if a target fluid weight has been reached, and fluid flow can be shut off at the appropriate time.

A system determines an interaction period during which a fuel dispensing operation is performed at a fuel dispensing terminal. The system determines a measured volume per unit time parameter associated with fuel dispensed from the fuel dispensing terminal by dividing the determined volume for fuel by the interaction period. The system compares the measured volume per unit time parameter with a threshold volume per unit time parameter. In response to determining that the measured volume per unit time parameter is less than the threshold volume per unit time parameter, the system retrieves a video feed that shows the fuel dispensing terminal during the fuel dispensing operation. The system creates a file for the fuel dispensing operation. The system stores the video feed in the created file.
