Claims (1)

  1. Устройства для измерения скоростей потоков каждой составляющей двухфазного потока, состоящего из газа и жидкости, или трехфазного потока, состоящего из воды, нефти и газа, включают первый каскад объемного расходомера и второй и третий каскады импульсных расходомеров, подсоединенных последовательно по ходу потока к каскаду объемного расходомера и в которых соотношение скоростей между газом и жидкостью на последовательном пути потока поддерживается равным единице. Процессор рассчитывает скорости потоков составляющих потока с помощью решения уравнения объемного потока и сохранения количества движения или энергии, определяющие поток через первый - третий каскады. Способ состоит в том, что определяют скорости составляющих потока, определяют, используя выходной сигнал объемного потока с первого каскада и выходные сигналы потока количества движения с упомянутых второго и третьего каскадов, и на индикаторе отображают поток составляющих жидкости и газа или нефти, воды и газа потока. Для измерения трехфазного потока обеспечивают измеритель водной фракции с цепью определения величины водного потока, которая затем используется в процессоре для определения потока остальной жидкости. Второй и третий каскады импульсных расходомеров можно выполнять с помощью двух отдельных импульсных расходомеров или с помощью одного импульсного расходомера, такого как расходомер с трубкой Вентури, имеющее точки отбора давления для получения по крайней мере двух измерений перепада давления. В том случае, если плотность жидкой составляющей известна, достаточно одного каскада импульсного расходомера.
