Abstract
The meter has two or more electronic integrator circuits (I1, I4) each of which is associated with a counter (C1, C4) indicating the consumption of a particular unit. The amplifier (2) compares an input signal (e) delivered by a measuring appts. with a reference value (Vs) proportional to one of the thresholds separating the counters. The subtractor (3) delivers a signal proportional to the former signal (e) minus the reference value (Vs), for directing the input signal (e) towards one integrator when it is less than the reference value (Vs) and towards the second integrator when the input signal (e) is above the reference value (Vs).
