Electric generator for producing electric energy by hydraulic thrust in water pipes or gas pressure in gas pipes, has rotor that is integrated in water meter or gas meter, where no current flows through rotor

摘要

The electric generator has rotor that is integrated in the water meter or gas meter, where no current flows through the rotor. A radio-free electric generator is built on magnet basis. The distance between gas pipe and generator is selected such that no danger exists.
