LIQUID METERING DEVICE Russian patent published in 1997 - IPC

FIELD: automatic control. SUBSTANCE: device has annular count register, flip-flop, two pulse shapers, inverter, liquid metering unit, piping, n process units, n electromagnetic valves, resistor, generator, and n control channels, each incorporating D flip-flop, pulse shaper, two resistors, four NAND gates, AND gate, indicator, end power amplifier. Device stores interrogation signals from n process units and processes them in turn, that is, yields required portion of liquid by means of single metering unit. Device also provides for visual monitoring of metering process and requests for desired amount of liquid. EFFECT: enlarged functional capabilities and reduced material input. 1 dwg
