METHOD AND DEVICE FOR MEASURING CONCENTRATION OF SOLID CONTAMINATION IN FLUID FLOW WITH UNSOLVED GASES Russian patent published in 2006 - IPC G01N21/49 

FIELD: measuring technique.

SUBSTANCE: method comprises separating reference flow of dispersion fluid in the hydraulic cyclone-generator, removing babbles of unsolved gas in the hydraulic cyclone-air separator, and preparing liquid phase for using it as a reference one. The reference fluid that enters the working cell for calibration flows through a super fine filter mounted in the detachable container. The extent of fluid purification is judged by comparing the signal from the reference flow entering the cell with the signal from the solid turbidity primary standard. The device comprises sampling three-way cock whose first outlet is connected with the inlet of the hydraulic cyclone-generator and second output is connected with the working cell and sampling cock. The hydraulic cyclone-generator is connected with the discharging three-way cock whose one outlet is connected with the outlet pipeline and second outlet is connected with the inlet of the hydraulic cyclone-air separator whose top drain opening is connected with the outlet pipeline. The bottom relief opening of the hydraulic cyclone-generator is connected with the inlet to the working cell and sampling cock and to the outlet pipeline through the second outlet of the drain three-way cock.

EFFECT: prolonged service life and enhanced accuracy of measurements.
