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.
Claims12
A software program product stored in one or more non-transient memory media, that, when executed by operation of one or more computer processors, performs operations comprising:
- receiving water meter readings from a plurality of on-site water meters powered by pressure changes in a water pipeline network;
- and
- receiving and storing water meter readings received via wireline or wireless communication network, when there is a pressure change in the water pipeline network.
A kit, comprising:
- an on-site self-powered water meter reading and transmitter system deriving operation power from pressure changes of a fluid in a water pipeline network, the reading and transmitter system comprising:
- a piston or a membrane configured to load a mechanical spring of a spring-loaded generator to extract mechanical energy from pressure changes in the water pipeline network,
- wherein the piston or membrane is mechanically driven by pressure changes in the water pipeline network,
- wherein the piston or membrane drives the mechanical spring storing mechanical energy, and
- wherein the mechanical spring when released is configured to drive an electro-magnetic motor and generate electric power
- configured to power a reading of a water meter and transmission of the
- water meter reading to a receiver, and
- a cut-off valve configured to:
- provide an interface for the piston or membrane to sense water pressure in the pipeline network, and
- install to the water pipeline network.
