FIELD: measurement equipment.
SUBSTANCE: invention relates to the field of mechanical engineering and can be used in rocket, aviation and other technical applications where the systems with tanks with working liquid are used and which are imposed by high requirements in view of the content of mechanical contaminants. Determination of the content of contaminants in the fuel supplied to the rocket unit tank is performed pre-gaging. The gaging includes temporary connection of the filling pipeline outlet a the drain line containing a control filter, the unit upstream the pipeline for adding into the liquid flow of artificial pollutants, passing through the pipeline of the liquid added by the artificial pollutants, with measurement of the volumes of liquid passed through the pipeline and the sampling line, and the pollutants settled on control filters of the drain line and the sampling line, and determination of correction coefficient. The formula for assessment of the correction coefficient is offered. For determination of the pollutant content in the liquid passed into the tank the formula containing the correction coefficient is offered. As far as the determination is performed in view of pre-gaging performed with adding of liquid flowing in the filling pipeline, of pre-set amount of artificial pollutants and in view of possible errors of manufacture and installation of sampling devices, the results of determination using the offered method will characterise the content of pollutants in the fuel supplied to the rocket unit tank with higher accuracy.
EFFECT: improvement of accuracy of determination of the content of pollutants in the fuel supplied to the rocket unit tank and decrease of financial and labour costs.
