Abstract

Изобретение относится к устройству для измерения уровня загружаемого материала (12) в резервуаре (11), содержащему чувствительный элемент (2) и блок (4) регулирования/оценки. В основу изобретения положена задача создания устройства, которое обеспечивает оптимальное определение и/или контролирование уровня заполнения в резервуаре (11). Задача решается с помощью чувствительного элемента (2), выполненного так, что его можно использовать в соединении, по меньшей мере, с двумя различными способами измерения соответственно, что чувствительный элемент (2) работает, по меньшей мере, в двух различных рабочих режимах, что блок (4) регулирования/оценки использует чувствительный элемент (2) в соответствии, по меньшей мере, с одним из двух способов измерения соответственно, по меньшей мере, в одном из двух рабочих режимах, и что блок (4) регулирования/оценки на основании данных измерения чувствительного элемента (2), полученных с помощью, по меньшей мере, одного способа измерения, соответственно, во время, по меньшей мере, одного рабочего режима, определяет уровень загружаемого материала (12) в резервуаре (11).Международная заявка была опубликована вместе с отчетом о международном поиске.
