Two-point laser doppler gas and fluid flowmeters

The technique of fluid and gas flow measurement in the large diameter pipelines based on Laser Doppler Anemometry was inspected. To reduce errors caused by deformation of the velocity profile, we suggested measuring the velocity at two points of cross section of pipeline. The errors in flow measurement were estimated as well as the possibility of its reduction was considered. We suggested the optical circuit of two-channel Laser Doppler Sensor and Doppler signal processing.

Keywords: Flow, fluid, gas, profile, error, laser.

The main directions and methods to improve the accuracy of the primary state standard of temperature in the range above the freezing point of silver

Temperature measurement is one of the most claimed measurements in science and industry. Primary state standard of unit temperature was revalidated in 2007, but all the growing demands of industry lead to the necessity of preventive arrangements to improve the accuracy of temperature measurements on the highest level. Construction of comparator performing reproduction and transmission units in the range above the silver freezing point has many opportunities for research and step-by-step improvements. In this work the directions and methods of reducing the individual components of uncertainties of radiators and the comparator are described.

Keywords: primary state standard, spectrocomparator, tungsten ribbon lamps.

Investigation of temperature influences of spectrocomparators optical system of primary standard of temperature

During the research of the primary state standard of temperature was revealed a significant effect of temperature change in a room to the measurement results. The reason is the instability of the optical system due heating the supporting elements. The results of the effect of local heating by optical channel comparator and a description of the means used to reduce this influence are shown in this paper.

Keywords: specrtocomparator, optical system, monochromator, thermostabilization.
