Abstract
According to the invention, the device for granulometric analysis of particles contained in fluids comprises a feeding channel and a receiving channel intended for passage of a fluid under investigation. The two channels communicate with each other through a nozzle. The ratio between the diameters of the nozzle and the receiving channel is in the range of 1/4 to 1/7. The receiving channel is provided with transparent windows for passage of a light flux emitted by a lighting means through the fluid in that channel. The device further includes a light-sensitive means to receive light reflected from particles contained in the fluid.
Claims4
A device for granulometric analysis of particles contained in fluids, comprising:
- a feeding channel having an inlet and an outlet;
- a nozzle arranged at said outlet of said feeding channel;
- a receiving channel having an inlet and an outlet;
- its inlet communicating through said nozzle with said outlet of said feeding channel;
- said feeding and receiving channels being intended to contain a fluid pumped therethrough;
- said receiving channel having aligned windows formed therein for exposing the fluid to a light flux and arranged on opposite sides of the channel;
- a lighting means whose optical axis is spaced from and extends at an angle to the axis of said windows, said windows being positioned in a portion of said receiving channel closely spaced from said nozzle so that the optical axis passes through fluid flowing in a diverging flow path;
- a third window formed in one of said channels, intended to receive light reflected from particles contained in the fluid in the diverging flow path;
- a light-sensitive means whose optical axis extends through the point of intersection of the axis of said nozzle and the optical axis of said lighting means, said light-sensitive means being arranged opposite to said third window;
- the ratio between the diameters of an outlet of said nozzle and said receiving channel being in the range of 1/4 to 1/7.
