ABSTRACT:
The volume of liquid or gaseous media contaminated with solids is measured discontinuously. To this end, an accurately measured volume of a pure medium is passed through a measuring device intended for measuring the volume of a contaminated medium. The number of the pulses produced by the passage of the pure medium through the measuring device is stored. The contaminated medium is thereupon passed through the measuring device until the number of pulses transmitted by the measuring device corresponds to the stored number of pulses. To further improve the accuracy in measurement, it is possible for the same amount of the pure medium to be passed once again through the measuring device. The number of pulses thereby produced is stored and compared with the number of pulses produced and stored on the first passage of the pure medium through the measuring device. The number of pulses last stored is modified by half the difference between the two numbers of pulses stored. In the next following metering cycle, contaminated medium is passed through the measuring device until the number of pulses produced by the measuring device corresponds to the number of pulses modified.
