Description
Известные вибрационные способы измерени массового расхода недостаточно точны, особенно при измерении пульсирующих потоков .The known vibration methods for measuring the mass flow rate are not accurate enough, especially when measuring pulsating flows.
Предлагаемый способ отличаетс от известных тем, что с целью повышени точности измерени участку трубопровода сообщают периодические колебани и измер ют врем затухани свободных колебаний участка трубопровода между двум фиксированными уровн ми колебаний, обратно пропорциональное количеству прощедшей за это врем среды .The proposed method differs from the known ones in order to improve the accuracy of measuring the pipeline section, periodic oscillations are reported and the damping time of the free oscillations of the pipeline section between two fixed vibration levels, which is inversely proportional to the amount of medium that passed through this time, is measured.
Измерение расхода жидких газообразных веществ, их смесей и пульп по предлагаемому способу происходит в единицах массы прощедшего через расходомер вещества.The measurement of the flow rate of liquid gaseous substances, their mixtures and slurries according to the proposed method occurs in units of mass of the substance that has passed through the flow meter.
При свободных колебани х трубки затухание во времени идет по экспоненциальному закону, а показатель затухани пропорционален массовому расходу протекающей через нее жидкости.With free tube oscillations, the damping in time goes exponentially, and the damping rate is proportional to the mass flow rate of the fluid flowing through it.
Согласно данному способу измер ют врем затухани амплитуды колебани трубки отAccording to this method, the decay time of the amplitude of the tube oscillation from
одной фиксированной амплитуды до другой при периодическом возбуждении колебаний в момент достижени амплитуды колебаний определенной величины.one fixed amplitude to the other with periodic excitation of oscillations at the moment of reaching the amplitude of oscillations of a certain magnitude.
Этот способ может быть применен дл измерени как стационарных, так и пульсирующих потоков, а также двухфазных потоков , каким вл етс , например извлекаема из скважины сыра нефть.This method can be applied to measure both stationary and pulsating flows, as well as two-phase flows, such as, for example, crude oil extracted from a well.

Предмет изобретени Subject invention
Способ измерени массового расхода жидкостей и газов путем сообщени колебаний участку трубопровода со средой, отличающийс тем, что, с целью повыщени точности измерени , участку трубопровода сообщают периодические колебани и измер ют врем затухани свободных колебаний участка трубопровода между двум фиксированными уровн ми колебаний, обратно пропорциональное количеству прощедщей за это врем среды.A method for measuring the mass flow rate of liquids and gases by communicating vibrations to a pipeline section with a medium, characterized in that, in order to increase the measurement accuracy, periodic vibrations are reported to the pipeline section and the damping time of the free oscillations of the pipeline section between two fixed vibration levels is inversely proportional to the quantity goodbye for this time environment.
