Способ определения уровня диэлектрических жидкостей по параметрам модели ёмкостного датчика уровня

Abstract

The method for measuring dielectric liquids level using an equivalent circuit of capacity level sensor and an equivalent circuit of long connection wires was considered. This method allows to eliminate the influence disturbing factors of long connection wires affecting the measurement result accuracy and to increase measurement reliability. The requirements to capacity level sensor are described. The analytical expressions for capacity filling level sensor and equivalent circuit of long connection wires parameters calculation are presented as long as the components of measurement error of fueling level.
