Patent number: 10173884Abstract: 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.Type: GrantFiled: June 9, 2015Date of Patent: January 8, 2019Assignee: QT TECHNOLOGIESInventors: Gerasimos A.
