DEVICE METERING LIQUID MEDIA Russian patent published in 1997 - IPC

FIELD: volumetric metering of liquids. SUBSTANCE: device has short-circuiting piston freely moving over length of measuring vessel and separating space of vessel from metered liquids, retunable SHF generator. One of its two controlling voltages is supplied to klystron repeller of SHF generator from control unit providing for high-accuracy successive feed of doses of corresponding liquids into measuring vessel and for discharge of mixture from it. One of two vibrators manufactured in the form of hollow metal tube is joined to device forming excessive pressure in measuring vessel. Under its action short-circuiting piston returns to initial position at moment of drain of metered liquids. EFFECT: increased accuracy of simultaneous metering of two liquids in certain ration and provision for metering of conductive liquids. 2 cl, 4 dwg
