  • Patent number: 4969365
    Abstract: In a method for measuring the volume of a liquid flow through a measuring chamber (2) during a measuring period, a pulse generator (12) is caused to emit a number of pulses corresponding to the volume. In the measurement, the measuring period is divided into a number of measuring intervals. During each measuring interval, the pulses from the pulse generator (12) are detected, each detected pulse is multiplied by a flow correction factor, the corrected pulse values are added to a summation variable, and this summation variable is multiplied by a volume conversion factor for determining the liquid volume. The separate determined liquid volumes are thereafter summed up for all measuring intervals during the measuring period.
