Results of researches for new method for metrological assurance of mass measurements on conveyor weigher

Abstract

The paper considers the issue related to calibration of conveyor weigher in laboratory environment for its usage as etalon and the subsequent transfer of a unit of linear density from them to the transported means of comparison – the measure of linear density. The equations of the mass flow in instant hopper-conveyor system are got. The algorithm of etalon conveyor weigher calibration is developed on the results of mass measurement in hopper at work process of hopper-conveyor instant system which doesn’t require passing a known fixed mass through a conveyor weigher. The transfer way of linear density unit from etalon conveyor weigher to linear density measure with accuracy required by measurement chain is proposed.
