Description
Technical field
The present invention relates to a kind of fluid velocity meter, relate in particular to a kind of magnetic fluid velograph.
Background technology
In existing production, convection cell speed detects the mode that conventionally adopts fluid to promote turbine and carrys out test fluid speed, but because turbine is that mechanical motion in use very easily cannot accurately record fluid velocity because impurity in fluid causes turbine rotation out of true or turbine is stuck, turbine also very easily causes line clogging to affect fluid motion simultaneously.
Summary of the invention
In order to solve, existing fluid velocity meter fluid is easily caused turbine rotation out of true by impurity or turbine is stuck cannot accurately record fluid velocity, and turbine also very easily causes line clogging to affect the shortcoming of fluid motion simultaneously, the invention provides a kind of magnetic fluid velograph.
The technical solution adopted for the present invention to solve the technical problems is: described magnetic fluid velograph, described magnetic fluid velograph is provided with velograph body, in velograph body, be provided with cavity, cavity cross section is quadrilateral, velograph body two ends are provided with connecting pipe, this volume surrounding of velograph is provided with magnetic shielding cover, in the magnetic shielding cover of velograph body one opposite flank, be provided with magnet, velograph body is provided with between two faces of magnet and forms one direction magnetic field, the opposite face that velograph body is not provided with magnet is provided with pole plate, the outside surface of pole plate is combined with insulcrete, pole plate is connected with the control enclosure of peripheral hardware, control enclosure is provided with terminal box, in terminal box, be provided with the signaling interface of remote signal transmission.
Further, described magnet is permanent magnet.
Further, described control enclosure surface is provided with velocity indicator.
Further, between described pole plate, fluid flow direction is vertical with the magnetic direction that permanent magnet forms.
Further, described connecting pipe surface is provided with connecting thread.
The invention has the beneficial effects as follows: adopt magnetic fluid generating technology record conductive fluid tube wall potential difference (PD) indirectly obtain pipeline fluid velocity inside avoided affecting pipeline inner fluid proper flow simultaneously machinery-free to relatively rotate the life-span longer.
