Abstract
УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ РАСХОДА ЖИДКОСТИ И ГАЗА, содержащее последовательно соединенные дат8 чик плотности, первый аналого-цифровой преобразователь и первый делитель частоты , триггер, выход которого соединен с первым входом схемы И , а также датчик расхода , второй аналого-цифровой преобразователь , шифратор, кварцевый генератор и накопительный счетчик, отличающеес тем, что, с целью повышени точности измерени путем коррекции нелинейной зависимости выходного сигнала датчика расхода, в него введен второй делитель частоты, счетный вход которого соединен с выходом кварцевого генератора, установочные входы через шифратор и второй аналого-цифровой преобразователь - с выходом триггера, а выход - с вторым входом схемы И, выход схемы И через первый делитель соединен с входом накопительного счетчика, а выход датчика расхода - с входом триггера. (Л 77A DEVICE FOR MEASURING FLUID AND GAS FLOWS, containing a series-connected density sensor, a first analog-to-digital converter and a first frequency divider, a trigger whose output is connected to the first input of an AND circuit, and a flow sensor, a second analog-to-digital converter, an encoder, a quartz crystal a generator and a cumulative counter, characterized in that, in order to improve the measurement accuracy by correcting the non-linear dependence of the output signal of the flow sensor, a second frequency divider, counted the input of which is connected to the output of the crystal oscillator, the installation inputs through the encoder and the second analog-to-digital converter to the trigger output, and the output to the second input of the And circuit, the output of the And circuit through the first divider is connected to the input of the storage meter, and the output of the flow sensor from trigger input.
