Measuring of substance concentration in water solutions
The paper considers the results of research of fish brining in the layer. The change of brine density according to the fish layer thickness at brining capelin and mackerel fillet has been studied. The dependence of uniformity of fish specimens' brining according to the salting layer thickness on temperature, brine and irrigation density has been found. The suboptimum conditions of salting of capelin layer (170 mm) and mackerel fillet (150 mm) have been determined. These conditions allow receiving the semi-finished product with the salt content equal to 4-5 %.

On radiowave resonator method of measurement of physical properties of liquids with dielectric losses
The paper describes the principle of operation and construction of radiotorsiographs (PT-660), technical information about these devices and some auxiliary equipment, AF characteristics obtained on a stand, information about software applied during these devices' operation. The errors of measurements while using radiotorsiographs of this type have been analyzed, the methods of errors' correction have been considered as well.

Radiofrequency resonator for measuring physical properties of liquids
Radiofrequency (RF) resonator measuring device for determination of physical properties of liquids has been proposed. The device contains RF sensor that is a section of modified coaxial line with U-shaped inner conductor. Distant location of electronic unit of the device from a monitored object can be provided. Mathematical model of the RF sensor has been proposed. It gives ability to calculate output characteristic of the device and to optimize parameters of the RF sensor in order to increase its sensitivity to measured physical properties of a liquid and to provide unambiguity of measurement results.
