Description
Способы измерени скорости жидкости, протекающей по трубопроводу , по удельному весу пульпы и величине деформации стенки трубопровода не обеспечивают достаточно высокой точности измерени .Methods for measuring the velocity of a fluid flowing through a pipeline, according to the specific weight of the pulp and the amount of deformation of the wall of the pipeline, do not provide a sufficiently high accuracy of measurement.
В предлагаемом способе этот недостаток устранен. Сущность изобретени заключаетс в измерении ме.ханического напр л ени в стенках трубопровода на двух различных по диа.метру участках.In the proposed method, this disadvantage is eliminated. The essence of the invention consists in measuring the mechanical stress in the pipeline walls at two different diameters.
На чертеже Показана схема устройства дл осуществлени описываемого способа.The drawing shows a diagram of an apparatus for carrying out the described method.
На трубопроводе 7 в двух его участках с разными диаметрами с помощью тензо.метров 2 н 3, включенных в электроизмерительные мостовые схемы 4 и 5, измер ют механические напр жени в стенках. С мостовых схем напр жение тока через усилители 6 и 7 поступает на электроизмерительный показывающий прибор 8.In the pipeline 7, in two sections with different diameters, tensile meters 2 and 3, included in the electric measuring bridge circuits 4 and 5, measure the mechanical stresses in the walls. From bridge circuits, the voltage through the amplifiers 6 and 7 is supplied to an electrical measuring device 8.
Предмет изобретени Subject invention
Способ бесконтактного из.мерени скорости потока жидкости в трубопроводе с применением установленных на различных у-.астках трубопровода двух тензодатчиков, измер юидих механическое напр жение в стенках трубопровода, пропорциональное скорости жидкости, присоединенных в качестве плеч к двум мостовы.м схемам, включенны.м последовательно и встречно и нагруженным на стрелочный измерительный прибор или другой индикатор, проградуированный непосредственно Б единицах скорости потока жидкости, отличающийс тем, что, с целью повышени точности способа, измерение механического напр жени в стенках трубопровода производ т на двух различных по диаметру участках трубопровода с равными или различными по толщине стенками.The method of contactless measurement of the flow rate of a fluid in a pipeline using two strain gauges installed on different pipelines, measured by mechanical stress in the walls of the pipeline, proportional to the velocity of the fluid, connected as shoulders to two bridges, included sequentially and counter and loaded on a dial gauge or other indicator, calibrated directly by B units of fluid flow velocity, characterized in that, in order to increase the NOSTA method, measurement of the mechanical stress in the walls of the pipe produced on two different diameter portions of the pipeline with equal or different thickness walls.
