METHOD AND APPARATUS FOR VOLUME DETERMINATION

摘要

In a method for determining the volume of fuel being dispensed from a fuel pump unit, a correction of the number of pulses generated by a pulse generator corresponding to the volume flow rate when dispensing fuel is carried out. The purpose of the correction is to produce a predetermined number of pulses per unit of volume of fuel. The correction comprises skipping every Nth generated pulse or adding a pulse in addition to the pulses generated for every Nth generated pulse. This correction, which can be made continuously during volume determination and which does not require any multiplications, is preferably realised by a processor unit and its associated software in an apparatus for volume determination. A method for carrying out calibration for determining N is also disclosed.
