Disclosed is a batteryless counter (1) for gas or water meters having at least one Wiegand sensor (2) or another power generating element and an evaluation circuit (10) connected thereto for processing a pulse (31), and the batteryless counter (1) feeds the pulses (31) generated and processed by the Wiegand sensor (2) to an isolator (17), and that at the output of this isolator (17) a pulse duration setting (18) is disposed, which processes the pulses (31) simultaneously counted via the counting circuit (4) by a pulse selection circuit (6) and converts the other pulse shapes/pulse frequencies and guides them outwards.
