DEVICE FOR BATCHING ALKALINE REAGENT OF SODIUM ANALYSER Russian patent published in 2019 - IPC B01J4/02 G01N31/00 G01F13/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement equipment and can be used in analytical monitoring instruments, measuring ions of sodium ions in process liquids, – in nutrient and chemically desalted water, in steam condensate of high pressure boilers and turbines, at thermal and nuclear power plants, chemical and food industries, as well as in other industries. In the device for dosing an alkaline reagent of a sodium analyser, the reagent vessel is cylindrical, provided with a hermetically sealed cylinder-conic cover, under which there is a gas-permeable membrane forming with an inner surface of the cover a saturation chamber with vapors of an alkaline reagent, a channel which supplies the controlled medium into the saturation chamber is made tangentially in the lower part of the cylindrical wall of the cover, and channel, discharging controlled medium, is made vertically in top conical part of cover. Vessel has a filling hole equipped with a tight plug.

EFFECT: design of a small-size reliable dosing device of alkaline reagent, simple and easy to use, which provides high stability and accuracy of measurements.
