Description

Известные способы и устройства дл  измерени  скорости нотока и расхода провод щих жидкостей, в которых потоку жидкости сообщают вращение и определ ют скорость по величине электродвил ущей силы, наводимой в жидкости переменным магнитным полем, с помощью катущки возбуждени , расположенной на магнитопроводе, конструктивно сложны и неудобны в эксплуатации.The known methods and devices for measuring the velocity of the current and the flow of conductive liquids, in which rotation is reported to the fluid flow and determine the velocity by the magnitude of the electrill, the force applied by the alternating magnetic field to the fluid using an exciter located on the magnetic core are structurally difficult and inconvenient in operation.

Предлагаемый способ лишен указанных недостатков и отличаетс  тем, что в начале измерительного участка жидкости сообщают вращение посредством периодически включаемого вращающегос  магнитного пол  и при этом фиксируют момент включени  вращающегос  магнитного пол , а затем в одной или нескольких точках трубопровода фиксируют с помощью индуктивных датчиков момент по влени  на них электродвижущей силы, наведенной при прохождении вращающейс  части потока.The proposed method is devoid of these drawbacks and is characterized in that at the beginning of the measuring section of the liquid rotation is reported by means of a periodically switched on rotating magnetic field, and the moment of turning on the rotating magnetic field is recorded, and then at one or several points of the pipeline the moment of occurrence these electromotive force induced by the passage of the rotating part of the stream.

На чертеже показана схема устройства дл  осуществлени  предлагаемого способа.The drawing shows a diagram of an apparatus for carrying out the proposed method.

Вокруг трубопровода 1, внутри которого движетс  поток электропроводной жидкости или газа, устанавливаетс  приспособление 2 дл  сообщени  потоку вращени , выполненное в виде двух полуколец, образующих при наложении на трубопровод подобие статора трехфазного электродвигател . На трубопроводе установлены также на некотором рассто нии друг от друга два электромагнита 3 к 4 дл  создани  магнитных полей, пронизывающих поток.A device 2 is installed around the pipeline 1, inside which the flow of an electrically conductive liquid or gas is installed, to communicate the rotational flow, made in the form of two half-rings, which form a three-phase electric motor when a pipeline is applied. Two electromagnets 3 to 4 are also installed at a distance from each other to create magnetic fields penetrating the flow.

В плоскост х поперечных сечений, проход щих через магниты, под углом 90 к их магнитному полю на трубопроводе установлены катущкй с магнитопроводом 5. В момент прохождени  вращающейс  части пэ№ 118992- 2 In planes of cross sections passing through the magnets, at an angle of 90 to their magnetic field on the pipeline, a coil with a magnetic conductor 5 is installed.
