IMPROVEMENTS INTRODUCED IN VOLUMETRIC FLOW METER OF POSITIVE DISPLACEMENT CONSISTING OF AN ENERGY AUTOGENING DEVICE NECESSARY TO THE ELECTRICAL SUPPLY OF THE RESPECTIVE CONVERTER

摘要

Improvements to positive displacement volumetric flow meter consisting of a self -generating energy device required for the electrical supply of the respective converter, improvements are introduced into a volumetric flow meter (mv) of the CO -type Time by a primary element /measuring chamber (cm) and a secondary element /converter (cv);In the measuring chamber (cm) the pair of gears (31) and (32) which rotate around the axles (41) and (42) and which, by conventional process, move;In a flow (f),A certain volume (v) of liquid for each complete revolution of the set of gears (31) and (32). A volumetric flow meter (mv) provides for an autogenerator electrical energy device (100) that uses the pair of oval gears (31) and (32) supported on their axes (41) and (42),With the partially hollow (p) axis where a transmitter axis (46) is housed attached to the rotor (52) and micro -alternator (53);A pair of magnets (45) and (47) are provided for which,Through the interaction of their magnetic fields,Enables the gear rotation (32) to be transferred to the transmitter axis (46);The converter (cv) contains the electronic circuits and the electric power self -generating device (100) which provides constant and continuous battery power (62). The so -called self -generation device (100) generates electric energy from three low -amplitude sine waves that then pass through a complete wave rectifier bridge,In order to convert the alternating voltage into continuous voltage to be processed by a second converter /voltage lift,Enabling the loading of a backup battery (62) with 4,2v load voltage.
