RADIOMETRIC MULTIVARIATE PLANT Russian patent published in 2019 - IPC G01T1/178 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment in nuclear power engineering. Radiometric multivariate plant comprises a measuring system consisting of three independent measuring channels of controlling volumetric radioactivity of inert gases, aerosols and iodine, each of which comprises the relevant detector comprising at least one detection unit and a device for accumulation and processing of the measurement results, besides, it comprises a sampling circuit, which includes two independent air feed lines, herewith it is equipped with a device for automatic support of air flow rate including an integral pumping device in the form of a pump of constant rarefaction arranged on the outlet air exhaust pipeline, herewith each independent air feed line is equipped with an electrically controlled valve and an air flow rate measuring device both connected with the device for accumulation and processing of the measurement results containing an analog-to-digital conversion unit and a microprocessor for statistical processing of the measurement results, herewith every device for accumulation and processing of the measurement results is connected with a device for control and display of the measurement results.

EFFECT: higher reliability of the radiometric plant operation.
