Fuel data collection unit with temperature compensation and over-fill prevention

摘要

A fueling data collection unit associated with a fuel transfer apparatus and for use with a system for managing fueling transactions of a fleet operator using fuel transfer apparatuses at one or more locations includes a fueling data interface module and a temperature compensation module. The temperature compensation module compensates for a volume variance of the fuel as a result of temperature variance from the standard temperature data to determine a volume correction factor at the measured fuel temperature, while the temperature compensation module uses the measured fuel temperature to determine a compensated, more accurate volume and/or mass of fuel dispensed through the fuel meter. In this way, the fuel data collection unit can accurately measure the volume and/or mass of fuel being delivered. This allows the provider and the recipient to more accurately sell/buy what was actually delivered and can avoid over-filling a fueling order.

主权项

1. An aircraft fueling data collection unit for use with a fuel meter having a register with a pulser and associated with a fuel transfer apparatus, the fueling data collection unit also being for use with a system for managing fueling transactions of an aircraft fleet operator for fueling multiple aircraft at multiple locations and using fuel transfer apparatuses at one or more locations, the fueling data collection unit comprising:
a fueling data interface module for receiving measured fuel data from the fueling meter register, pulser, or both; and the fueling data collection unit being provided with an over-fill prevention feature for using a pre-ordered refueling quantity to prevent the fuel transfer apparatus from transferring more than the pre-ordered refueling quantity to the aircraft, the over-fill prevention feature comparing the pre-ordered refueling quantity with a dispensed fueling quantity and once the dispensed fueling quantity reaches the pre-ordered refueling quantity, the fueling data collection unit generates a signal to discontinue refueling, wherein the measured fuel data and fuel density information at standard temperature are used to determine a volume correction factor that is used to compensate for fuel volume variance as a result of fuel temperature variance from the standard temperature fuel density data to avoid over-filling a fueling order.
