Description
по изменению уставки числе порций в блоке 2, либо уставки времени в блске 5. Если поток без пульсаций, то на выходе блока 3 сигналы, соответствующие/rti 0, отсутствуют и цикл измерени (минимальное врем аамера) определ етс величиной уставки чис ла порций & блоке 2, либо величиной уставки времени в -блоке 5, а цикл измерени заканчиваетс путем вьшачи сигналов в измеритель 1. Если поток имеет пульсацию, то на выходе блока 3 возникают сигналы, пропорциональные величине пульсации, которые преобразуютс в блске 4 в корректирующее воздействие и увеличивают уставку числа порций либо уставку времени на величину, пропорциональную разнице А TV , таким образом увеличива врем измерени потока. Корректирующее воздействие производитс в тече-- --х « .. а IC1G- . ние всего цикла измерени , каждый раз nouT Предлагаемый способ вл етс адаптирующимс не только по величине интегрального значени расхода, но и по величине пульсации потока. ормула изобретени Способ измерени дебита жидкости нефт ных скважин на групповых замерных установках по аЬт.св. № 435349, отличающийс тем, что, с целью повыщени точности измерени путем исключени вли ни пульсации потока, измер ют разность времени прохождени последовательных порций жидкости через измеритель и измен ют уставку числа порций либо уставку времени на величину, пропорциональную ку времени на этой разности.by changing the setpoint of the number of portions in block 2, or the time setting in blok 5. If there is no flow, then at the output of block 3 there are no signals corresponding to / rti 0, and the measurement cycle (the minimum time of the chamber) is determined by the value of the set number of portions &; block 2, or the time setting value in block 5, and the measurement cycle ends by signaling the meter 1. If the flow has a pulsation, then the output of block 3 produces signals proportional to the pulsation value, which are converted in blox 4 to a corrective action and increase a set number of chunks or a time set by an amount proportional to the difference A TV, thus increasing the flow measurement time. Corrective action is produced in the course of-- - x ".. and IC1G-. the whole measurement cycle, each time nouT. The proposed method is adaptable not only in terms of the integral value of the flow rate, but also in terms of the amount of flow pulsation. Formula of the invention. Method of measuring the flow rate of oil wells in group metering installations according to Tbc. No. 435349, characterized in that, in order to improve measurement accuracy by eliminating the effect of flow pulsation, the time difference between the passage of successive portions of fluid through the meter is measured and the set number of portions or time set is changed by an amount proportional to the time on this difference.
