Description

Horizontal integrated magnetic eddy street flow measurement and control instrument

technical field

The utility model relates to a magnetic eddy street flow measuring and controlling instrument, in particular to a horizontal integrated magnetic eddy street flow measuring and controlling instrument.

Background technique

The magnetic vortex flow meter is a vortex flow meter that uses the "Karmen" vortex principle, which is different from the piezoelectric detection method of most existing vortex flow meters, and adopts a new detection method of electromagnetic induction. When the conductive fluid flows through the sides of the vortex generating body of the triangular prism at a certain speed, an alternate vortex band is generated, which is called "Karman vortex". The permanent magnet in the package shell generates a magnetic field, which is the same as the vortex at the top of the electrode The frequency charge signal is sent to the flow integration and control unit through the wire for intelligent processing, to realize the display of liquid instantaneous flow and cumulative flow, as well as the communication and control between the flow data and the microcomputer system, and then through the flow integration and control The unit transmits the execution signal to the electric execution unit, and controls the flow of the fluid through the electric execution unit.

At present, the magnetic eddy street flow measurement and control instrument used is mainly a split type magnetic eddy street flow measurement and control instrument. The disadvantage is that the flow integration and control unit, the electric actuator and the valve body are separately arranged on the pipeline. On the one hand, The production cost of the product is greatly improved, and on the other hand, it occupies a large installation space and is inconvenient to carry.
