Description

one

The device relates to equipment used in the preparation of water for industrial and drinking water supplies; It can be used in a number of other branches of the national economy in the systems of coitrol technological processes, according to turbidity (transparency) of the controlled liquid.

A turbidity meter is known, which is a flow-through QUT, made in the form of a U-shaped tube, at the ends of the COLE of which there is a light source and a photo-iremia and a mirror at the bottom. A beam of light, propagating from the lighting lamp, passes through the thickness of the water being analyzed, is reflected from the mirror and, secondly, the second knee falls on the photoelectric detector.

However, in the photometric channel of a known millimeter, the surface (mirror) is solid, in contact with freshly traced water. In the course of operation, an IPROP can contaminate the mirror, as a result of which there will be a nulling of its surface and, therefore, inaccuracy measured.

The aim of the invention is to improve measurement accuracy.

For this, the axis of the tube (with the light source placed on it) coincides with the axis of the outlet opening of the container, behind which the photodetectors are located, facing the smallpox. This arrangement of elements

The device excludes the contact of a controlled liquid with a solid nozzle in the photometric channel; 1С1ст1мО, and, consequently, the probability of measuring the optical properties from: the measuring channel.

The proposed device allows the control of the ability of the gi.p, the bone without co-opting for the optical properties of the nagging channel.

The drawing shows a diagram of the device.

The device consists pz top capacity / with input 2 n siphon 3 tubes. One of the ends of the siphoin tube is placed into the lower tank 4, in Koropoii, the reinstalled fins are installed .5, and in the outlet in the bottom 5,; The tube 11 of the chink hole coincide.

In the screen, holes for photograin pliers and a donut-white light source are made in the screen //.
