Patent ID: 7963423

Claim:
A fuel dispensing unit for refueling vehicles, comprising: a fuel line having a fuel inlet; a fuel pump feeding fuel to a gas separator; a return fuel line in fluid communication with the fuel inlet and the gas separator, the return fuel line adapted to transfer a portion of fuel from the gas separator to the fuel inlet; a gas exit; and a fuel meter arranged downstream the gas separator to measure an amount of fuel dispensed at a fuel exit, wherein a sensor is adapted to indirectly measure an amount of gas in fuel flowing through the fuel line, by being arranged upstream the gas separator, and by measuring the amount of fuel flowing in the fuel line where the sensor is arranged, the amount of gas being measured and calculated by a control unit, by calculating a difference between the amount of fuel measured by the sensor and the amount of fuel measured by the fuel meter, wherein the sensor is arranged upstream of a coupling point between the return fuel line and the fuel inlet.
