Abstract
A system including a pulse-generating device can comprise of at least one analog sensor and at least one unit for signal-processing is arranged to detect the analog signal and to generate signal changes having a higher frequency. When generating signal changes in connection with the determination of the amount of fuel dispensed from a fuel pump unit and a frequency generator for generating a periodic analog signal having a frequency is generated, which corresponds to a fuel volume flow in the pump unit. The amplitude of the analog signal is detected and then signal changes having a higher frequency are emitted, which is dependent on and higher than the frequency.
