The unity of measurement as a concept and system (the possibilities of metrological legislation improving)

Based on the analysis of the limitations of legislation and the content of the recently adopted international documents it is proposed a new interpretation of the concept of unity of measurements: instead of the implementation of mandatory requirements for measurement accuracy go to the metrological traceability of measurement results. The corresponding redistribution of regulated objects between the legislation on Metrology and Technical regulation will contribute to the solution of some problematic issues and reduce the scope of state regulation in the field of ensuring the unity of measurements to the minimum necessary level.

Keywords: measurement, traceability, measurement assurance, legislation, metrological traceability, measurement standard, measurement tool, measurement methods, calibration, calibration.

Density, temperature and viscosity of crude oil relationship as the base for servo-system development

The problem of measurement instrument for oil plant as for light crude oils as for heavy crude oils – measurement of density, viscosity and temperature. Crude oil is developed as integrated complicated system, which need accurate analysis of physicochemical characteristics, that are high dynamical, have random time behavior. Inefficiency of measurement density, viscosity and temperature in laboratory is explained. Interrelation of given parameters is measured and mathematical description is given, graph of interrelation is shown. In article general principle of work of two bridges vernier circuit for physicochemical characteristics on pipeline is described, which explains actuality of solution.

Keywords: crude oil, density, viscosity, temperature, turbine, two bridges measurement circuit.

Research methods nanostructures Ni-Ge: Magnetic properties and interface

The magnetic properties and the morphology of the film structures of Ni-Ge, depending on the thickness of the layers. It has been found that films of Ni-Ge interface formed approximately the same composition throughout its depth. The temperature dependence of magnetization is different for the two processes FC and ZFC. At low temperatures there is an asymmetry of the hysteresis loop and its displacement along the axis of the magnetic field.

Keywords: physics of surfaces, thin films.
