Abstract

В измерительной и рабочей схеме для кориолисового расходомера предусмотрен цифровой процессор (DSP), который из сигналов датчиков колебаний оценивает только разностный сигнал (D) и сигнал (S1) одного датчика. Для разностного сигнала (D) определяют совпадающую по фазе составляющую (I) и квадратурные составляющие (Q) и регулируют усиление сигнала (S2) второго датчика так, чтобы исчезла совпадающая по фазе составляющая I разностного сигнала. Из квадратурной составляющей (Q) вычисляют расход (m) массы.Международная заявка была опубликована вместе с отчетом о международном поиске.
