The paper theoretically substantiates and experimentally confirms the possibility of checking mercury thermometers in temperature calibrators. The measurement equation has been compiled. The components of the transmission error of the unit of magnitude are estimated. Conditions are formulated that allow a priori to assess the possibility of checking a particular type of thermometer in a particular calibrator. All calculations are made taking into account the changes in the state verification scheme. The design of a special thermometer for studying the heterogeneity of the temperature distribution outside the working area of the calibrator channel is proposed. The dependence of the readings of a special thermometer on the depth of immersion is theoretically estimated. The disadvantages of the currently used method for determining the temperature of the protruding mercury column are noted. It is proposed to measure the temperature of the protruding column with a thermal imager, an accuracy analysis is performed. The results of experimental studies of the inhomogeneity of the temperature distribution outside the working area of the channel of the calibrator KT-2M are presented. The reproducibility of measurement results when checking thermometers in a calibrator and a liquid thermostat is estimated.","PeriodicalId":432853,"journal":{"name":"Kontrol'.

For a probe with a frequency of 2.5 MHz, an increase in the anisotropy parameter leads to a decrease in the value of the echo maximum, since the increased increase in the attenuation of the quasi-longitudinal wave in the layer is not compensated by a change in the double transformation coefficient. For different nominal angles of probe (45…60°), a noticeable change in the shapes of frequency spectra and echo pulses at different values of the anisotropy parameter has not been established. The effect of increasing the distance from the control surface to the axis of the cylindrical hole at a constant layer thickness on the change of the amplitude of the echo signal in the calculated range of values of the anisotropy parameter is shown.","PeriodicalId":432853,"journal":{"name":"Kontrol'.

The method under consideration is based on the use in the calculation of the pressure drop resulting from the location of the flaw detector in the pipe. For theoretical testing of the developed methodology, a calculation model of the pipeline was built using the example of a gas pipeline. The calculation method takes into account both the parameters of the pipeline and the pumped medium, as well as the gravity of the projectile itself, which minimizes errors in determining the coordinates of the defect and makes it possible to eliminate the defect faster and more efficiently. The sections of the article discuss, among other things, general information about the technological reliability of main pipelines, theses proving the relevance of the task, a description of the proposed method for solving it, as well as excerpts from the calculation algorithm, on the basis of which the pipeline model was developed, which allows determining the location of the pig when carrying out in-line diagnostics in this pipeline.","PeriodicalId":432853,"journal":{"name":"Kontrol'.
