Claims

1. The receiver of the magnetic induction flow meter, comprising a fluid flow velocity transducer made of a dielectric material in the form of a venturi with a nozzle and a diffuser connected by a channel having a rectangular cross section, built-in diametrically opposed electrodes and a casing with an electromagnetic induction source located in it, consisting of core with pole tips and field coils, as well as means of inclusion in the pipeline, characterized in that in the converter, in complements a rectangular parallelepiped, over and under the channel formed with recesses disposed therein ferromagnetic elements having a cross section matching the cross-section are simply supported on the pole pieces of the core mounted on the converter at the place of contact without gaps.

2. The device according to p. 1, characterized in that the height of the channel of the Converter is selected from the ratio:

where h is the height of the channel;
D is the diameter of the pipeline,
and the width of the ratio
h: 1 = 0.4,
where h is the height of the channel;
l is the channel width.

3. The device according to p. 1, characterized in that the length of the nozzle of the Converter is selected from the ratio
L _s = (1.5 ... 3.0) (Dh),
where h is the height of the channel;
D is the diameter of the pipeline;
L _s is the length of the nozzle.

4. The device according to p. 1, characterized in that the length of the diffuser of the Converter is selected from the ratio
L _d = (2.0 ... 4.0) (Dh),
where h is the height of the channel;
D is the diameter of the pipeline;
L _d is the length of the diffuser.
