Abstract
(EN)
PROBLEM TO BE SOLVED: To provide a telemeter of simple structure, having a long service life, dispensing with frequent maintenance, and dispensing with supplying power from the exterior.

SOLUTION: An electricity generation means 5 converts part of kinetic energy possessed by the flow of a fluid 1, such as gas or water passing through a pipe 2, into electric energy. A transmission/reception means 7 uses the electric energy to transmit data on an integrated flow volume of the fluid measured by a flowmeter 4 to an external base station via an antenna 8. Further, a secondary battery is installed to store therein the energy converted by the generation means. The stored energy is used to receive command information from the exterior requiring the transmission of the data on the integrated flow volume.
