METHOD OF DETERMINING NUMBER OF FERROMAGNETIC PARTICLES IN LIQUID OR GAS STREAM Russian patent published in 2012 - IPC G01N15/06 

FIELD: physics.

SUBSTANCE: method of determining number of ferromagnetic particles in a liquid or air stream, involving installation of a detachable element with a magnetic system perpendicular to a pipe, through which passes a portion of the stream moving through the pipe, characterised by that the liquid or gas passes through the detachable element, the liquid undergoes controlled collection with ferromagnetic particles for subsequent weighing, wherein the detachable element consists of a cylindrical housing with flanges for inlet and outlet of liquid or gas, and the inlet flange is hermetically connected to the collection pipe lying inside the pipe and moving in its cross-section from the horizontal axis to the inner surface and for synchronous joint movement with a permanent magnet which is joined through a telescopic rod. The magnetic system also consists of a permanent magnet which moves vertically on the outer surface of the cylindrical housing of the detachable element and ferromagnetic liquid which forms a film upon contact with the permanent magnet, which, in form of a piston, divides the cylindrical housing into a lower chamber for collection and a top chamber for subsequent weighing of the liquid or glass with ferromagnetic particles.

EFFECT: low power consumption and high accuracy of determining the number of ferromagnetic particles in a liquid or gas stream moving in a pipe.
