Disclosed is a battery-less meter (1) for gas or water meters, comprising at least one Wiegand sensor (2), and/or another energy-generating element, and an evaluation circuit (10) connected thereto for processing a pulse (31), wherein the battery-less meter supplies the pulses (31) generated and prepared by the Wiegand sensor (2) to a separator (17), and a pulse duration setting unit (18) is arranged at the outlet of said separator (17), prepares the pulses (31) that are simultaneously counted by the counting circuit (4) with a pulse dialling circuit (6), converts said pulses into other pulse shapes/pulse frequencies, and guides them outwards. |
