FIELD: liquid atomisation or spraying devices.
SUBSTANCE: invention relates to design of devices for metered introduction of liquid reagents into fluid flow and can be used in various industries. Weight proportioning unit includes reagent supply tank, hydrostatic weighing unit, metering nozzles, fluid flow meter and control system. Hydrostatic weighing unit includes a partially filled reagent measuring vessel with a cover. Cover is equipped with a strain gage, which touches the top of the semi-submerged weighing vessel located inside the measuring container. Consumption and measuring tanks are connected by gas equalizing line.
EFFECT: high-accuracy of non-volatile fluid dosages.
