FIELD: metering of liquids, for instance, insecticide liquids. SUBSTANCE: metering tank includes tank for metered liquid with overflow line, level gauge, feeding line with electromagnetic valve, at least one discharge line including at least one electromagnetic valve, guide for intake vessel or for cassette with intake vessels contact-free switch activating automatic equipment of time delay of turn-off of electromagnetic valve. Level of metered liquid at moment of operation of level gauge ensures hydrostatic pressure at which speed of flow rate of liquid through at least one discharge line and time of delay of shut-off of electromagnetic valve in it determine dose of released liquid and cross-section area of intake line secures gravity flow of liquid coming from feeding line if level gauge or electromagnetic valve in feeding line fail. EFFECT: increased metering precision, operational reliability, accuracy in positioning of intake vessel beneath discharge line, reduced labor input while filling intake vessel with metered liquid, possibility of unification of metering tank for different doses of liquids. 14 cl, 1 dwg |
