Wireless data collection unit for fuel management system
First Claim
1. A data collection unit for a fuel management system, comprising:
- a pulse transmitter that transmits pulse signals corresponding to a flow of fuel;
a configurable filter that attenuates the pulse signals received from the pulse transmitter;
a pulse accumulator that increments a counter for each input pulse signal;
a micro-controller that reads the pulse accumulator and calculates a volume of fuel based on the pulse signals; and
an RF module coupled to the micro-controller for producing RF signals.

Abstract
An electronic fueling data acquisition and wireless communications delivery system. The unit is mounted on Aircraft Fueling Vehicles and Aircraft Fuel Servicing Hydrant Vehicles (Hydrant Vehicles) and is hardwired to an external pulse transmitter. The pulse transmitter transmits pulse signals proportional to the volume of fuel that is being pumped. A software configurable hardware filter attenuates the input signal which is then counted by a pulse accumulator. When fueling ceases, the application software can convert the pulse signal values to an equivalent volumetric total. The information can then be wirelessly communicated to other devices without the need for maintaining paper hard copies.
