Audi’s success in the Le Mans Endurance Series was supported by Flux Pumps’ precision fuel measurement system made from stainless steel. In 2004 Audis won every race they have started, and held the lead for 80% of all race time. Race engineers must carefully meter the fuel taken on board at each pitstop, to maximise time on the circuit and the laps covered between stops. They use computers to determine the race strategy and refuelling windows. This year, Team Veloqx used a precision pumping and measurement system from Flux Pumps to improve the accuracy of fuel and race management. The Team Veloqx installation is the second that Flux has supplied to a motor racing team. The equipment, manufactured from stainless steel and explosion-proof to the AtEx 100a Directive, was supplied to Team Veloqx with a trigger gun and two types of motor – air-driven and electric – to suit conditions at different circuits around the world. The Flux system, comprising a sealless pump and precision flowmeter, is used to pump fuel from drums to the autonomous tank that, in turn, feeds the fuel to the cars. The flowmeter is programmed to stop the pump when the required amount of fuel is in the tank.
