dosing of small amounts (less than 20 cu.cm/h) of electrically conducting liquids to production process installations, in particular, to a flow of some other liquid. SUBSTANCE: the functions of flow transducer, compensator, adder, controller and adjusting control in the given device are accomplished by a conductivity cell is connected to an AC voltage source in parallel with an electrolyzer with a rectifier, and the limiting resistor is cut in between the AC voltage source and the conductivity cell. The electrolyzer is made with cathode and anode chambers separated by a porous partition. The gas space of one of the chambers is connected to the atmosphere, and the gas space of the other chamber is connected to a tank for dosed liquid. EFFECT: enhance reliability of operation of microdoser. 2 cl, 1 dwg
