<p>The invention refers to an electronic system meant to meter and register the fluids flowing through closed conducts. The system uses the method of locally reducing the conduct local cross section. In order to reduce the electric energy consumption and to have a simple construction, a direct interface with the pressure, differential pressure and temperature transducers. The whole system is controlled by a microcomputer, which switches the elements of the systems in a low electric energy consumption state while they are not in use.</p> |
