Description

one

The invention relates to the field of instrumentation, in particular, to devices for determining the effect of flow swirling on the stability of the metrological properties of flow transducers.

Known flowmeter, comprising a housing with mounted on a single axis screw threads, an apparatus and an impeller, a converter, an inlet and an outlet.

However, the known device does not allow adjusting the angles of the flow rate at the same time as the flow direction.

To create the required flow rate, for example, when examining the metrological characteristics of a flow meter in the device proposed, the flow diverter is installed with no possibility of changing, axially and kinematically connected to the transducer, and the inlet pipe of the flow meter is at right angles to itopnycy in the displacement zone I am a straightener.

The drawing shows an open flow meter, consisting of a body /, inlet and outlet pipes, an easily removable screw jetting device 2 mounted on the movable shaft 3, reversible in the axial direction by the screw 4, the measuring impeller 5, the transducer 6 mounted on the movable frame 7 connected to

rod, providing at any position of the guide apparatus the same position of the transducer in the plane of rotation of the turbine.

The device works as follows.

The flow of liquid (gas) enters the pipe A and through the windows B - into the pipe B. In this case, there is no swirling of the notoka. The rotation of the screw 4, the rod 3 moves in the directional screwdriver, the screw guide, enters the socket B, closes it behind the outlet windows B. The degree of twist is changed depending on the movement of the screw guide apparatus into the socket B behind the bullet windows.

At the same time, the molonast turbine, rotated by the effect of the swirling flow, together with the converter 6 generates an electrical signal with a frequency proportional to the degree of flow swirling.

PRE D ME Invention

A flow meter containing a cornus with an installed on one main streaming device an impeller, a transducer, an inlet and an outlet, distinguishes it by the fact that, in order to create the necessary flow rate, for example, to investigate the metrological characteristics of the flow meter, the streaming device mounted in axial direction and kinematically connected to the shaft

ralovate.i-.m, and nkholom the pipe is located at the right angle to the Cornus} - in the unplaced area | jet transfer apparatus.
