Known adaptive methods and devices with lagging of a hinged device for blowing into the device are as follows, because of the bubble in the air and the measuring tube, which has a very thick body that is easily painted glass. They do not give you a chance to determine a static value and a CRC value, but do not turn it on the same time as it is.

I have a shortage of utefanen in oniBeagam, below the invention as a result of I1cIr: ip optics and timecause to the device with a screen, la cotopha: a shadow of an air bubble is designed in an enlarged scale: a control thread, a shadow, a bubble, a bubble, a bubble, a bubble, a bubble, a bubble, a bubble, a bubble, a bubble, a bubble. rnuy tube.

A distinctive feature of the method is that the pressure of the air bubble in the cache1e re is regulated so that the size of the NRP maxigal mignal bubble of the pth order) is unchanged.

On the fit. 1 shows the scheme for the implementation of the method; in FIG. 2 chra; ITAP Jokoi oispoz.

The pribad consists of a glass tube (1) with a cn Nuty in the form of the tip of the end, which is slightly reloaded in 1Kzeylkuar (2) with the test specimen.

For conchoal, the luster of the surf air is equipped with an optical projection device of HiCTowHHKOM light (7) and a ptsoekinoy lens (8). located on the mnu i-toron from the tank with and consequently on the ditch, on the ipyryio to the side of which installed the screen (9).

In order to reduce the pressure in the injection unit, it is possible to observe a continuous curve of the rfOB-orhnost HOTfl tension of 1 n depending on the strength of the dynamic and oT.a.Tif4.eeK.OH values of the pressure / nor.
