SYSTEM FOR SUPPLY OF LIQUID CHEMICAL REAGENTS AND METHOD OF ACCOUNTING REAGENTS IN SUCH SYSTEM Russian patent published in 2016 - IPC E21B37/06 

FIELD: chemistry.

SUBSTANCE: system contains vessel for storing chemical reagent, pump-batcher, object of batching, control-measuring devices, placed in it, hydrostatic pressure sensor, placed in storage vessel, and control unit. Control unit is made with possibility of controlling pump-batcher depending on signals from hydrostatic pressure sensor and control-measuring devices. On the basis of signal control unit determines weight of chemical reagent in storage vessel, current consumption of reagent in object of batching is determined indirectly, through difference of chemical reagent weights in storage vessel after time intervals, specified in control unit.

EFFECT: accuracy of accounting chemical reagent is increased without changing its flowability and, consequently, with reduction of load on equipment.
