The article is devoted to the study of the features of continuous monitoring of changes in the color of information channels of passive pressure-temperature sensors, tracking the spectral distribution of the light intensity of the liquid crystal color depending on the operating conditions. The main direction of application of such sensors can be “screening” of chemically active environments, deployment of temporary objects of short-term use in conditions of a pandemic, or military operations, etc.

The work proposes the use of a unique method of creating passive, multifunctional, non-contact pressure-temperature sensors. The basis of this method is a combination of inorganic semiconductors and high-molecular organic cholesteric crystals. According to their morphology, such crystals represent a spiral structure that is sensitive to changes in external physical factors, such as temperatures, due to changes in the periodicity of the structure, which leads to Bragg diffraction scattering of light on it.

In this paper, the estimation error of Dr. Pole's empirical equation was evaluated using copper pipes of different diameters (0.00953, 0.0127, 0.01588 m), under different flow pressure conditions (0, 300, 500, 1000, 1500, 2000, 2500, 3000 L/h). To carry out the experiments, the following instruments were used: an air compressor, 2 flow valves, a needle valve, a gas rotameter, copper piping, pressure gauges and transmitters, a Norus data logger with 4 to 20 mA output signals, thermocouples, and thermoresistors.

Modern media not only (such as radio, newspapers, television or online journalism), but also the full range of media (e.g. theater, music, exhibitions, cinema, drama, opera, visual arts etc.) promote narrative – interpretive both the journalist and the audience the contexts of the realities referred to in the journalistic presentation. But with the introduction of holistic systems of ideologically united mass media, the narrative is no longer characterized by the temporality or length of interpretations.

Pumping stations that provide fluid transportation by pipeline are significant consumers of electricity. Energy overruns due to sub-optimal modes of operation of individual high-power units or sub-optimal number of simultaneously operating less powerful units are quite significant and can have a significant impact on overall energy consumption. Energy overruns at pumping stations also lead to significant overruns in electricity grid elements.

A calculation of the empirical relationships that link the volumetric compression, porosity and pressure in porous rocks of an arbitrary geological region is suggested. The calculation of correlations and empirical relationships between reservoir properties and parameters of elastic waves is conducted by the data of Zaluszany’s wells, which distinguish dry and oil-gas saturated rocks. A detection of oil and water by the density parameter is proposed. A unified algorithm for these calculations is built.
