ABSTRACT:
An apparatus and a method of measuring the volume of flowing media, especially of fuel, by means of a screw spindle volumeter, the method comprising the following steps: detecting the revolutions of a screw spindle by means of a sensor and producing pulses whose time sequence is representative of the angular speed of the screw spindle; repeatedly measuring the period of time between successive pulses; selecting, in dependence upon the respective period of time measured, a volume value predetermined for said period of time, said volume value being representative of the volume flowing through the volumeter per predetermined revolution angle of the spindle at the respective angular speed of the spindle; adding the volume values which have successively been selected for various time period measurements, and producing and preferably displaying a total volume value that is based on the sum obtained during the whole volume measurement by continuously adding the volume values.
