Abstract
A water meter reading device having a piston (503) or a membrane (527) that moves with the pressure changes of the water pipe (301, 501, 601) network. The movement charges a capacitor (704) with electric energy released for reading the water meter. This makes it possible to realize the system without a battery, as the electricity needed for reading the water meter, and communicating the water meter reading to the water company, is used at the same moment that the electricity is generated. This also has the consequence that the water meter readings occur at the same time as the pressure changes in the water pipe (301, 501, 601) network.
