METHOD OF PORTION WEIGHING OF DOSAGE OF LIQUID Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: method of portion weighing of dosage of liquid is performed by setting of vessel 1 into loading position, by opening of valve 12 for filling of vessel with portion of specified weight, by stopping of filling by shutting valve followed by emptying of vessel. In this case vessel hinged on axle 2 with gravity center displaced towards tipping over is returned into loading position each time with counterweight 5. Strength of current in immobile coil 8 with open ferromagnetic core 9 before filling is set by regulating element 11 in accordance with graduation characteristic. Magnetic circuit of coil core in this position is closed with ferromagnetic armature 6 made fast to outer surface of vessel. Filling is performed till moment of electromagnetic attraction of coil with closed magnetic circuit equals moment of tipping over gravity force of filled vessel. Vessel is emptied in process of tipping over. Counterweight is also imparted with damping capabilities when vessel moves. EFFECT: increased functional efficiency thanks to use of electromagnetic counterbalancing force, increased precision of operation due to partial suppression of internal force with movement of vessel. 2 cl, 1 dwg, 1 tbl
