1. 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.
