Velít I.D., Mikhailova Yu.V. Electromagnetic flowmeter modeling with complex kinematic flow structures
The paper discusses the features of a simulation approach to metrological characteristics study of electromagnetic flowmeters with complex flow profile. The equations for surface weighting functions are presented for turbulent and laminar flows.


Melínikov V.I., Drobkov V.P., Labutin S.A., Sharonov D.A. Investigation of ultrasonic waves propagation speed in oil-water emulsion
The paper presents the results of experimental studies of the relationship between ultrasonic waves propagation speed in oil-water emulsion and its moisture content (% vol. of water), temperature, and salinity.


Vavilov V.D. The development of a microsystem accelerometer with electrostatic force transducer
The results of theoretical development of a compensating accelerometer are presented. Its overall transfer function is derived, including the compensating device function the enabled the damping of vacuumized actuated parts of sensing elements in the loop.


Shilin A.N. Modeling of processes in electronic measuring transducers
The procedures for linear and nonlinear electronic devices analysis and digital filters synthesis based on analog models are adduced. The modeling of signal converters is based on operator-discrete techniques application using Z-transform techniques that enables the ease of transformation from the representation to the original function. The recommendations are made on selecting the sampling period and the maximum degree of the transfer function.


Nedelíko A.Yu. Thermal radiation-based temperature measurement
The paper analyzes the state of the art in Russian pyrometry and provides a theoretical background of temperature measurement based on thermal radiation of the object under investigation. The existing thermal radiation sensors are reviewed, their merits, drawbacks, and application features are discussed. Performance data for some pyrometer models developed by Etalon Scientific and Production Company are included.


Kostyukovsky S.R., Zhakovsky E.V., Grachev I.A., Morozova I.V. Non-contact temperature meters: Kelvin Series pyrometers from Dipole Design Office
Featured attributes of Kelvin Series pyrometers developed by Dipole Design Office are briefly discussed.


Mirskov A.S., Shilyaev S.N. A control system for structures sound insulation evaluation by means of adjacent reverberation chambers
A control system that enables automatic measurement of building structures sound insulation with adjacent reverberation chambers method and provides a test log is presented. The system was developed by RudnevĖShilyaev JSC.


Kalach A.V., Ryzhkov V.V. The automation of substance analysis using piezoelectric resonator sensors
The paper informs about the creation of a new automated substance analysis system using piezoelectric resonator sensors. Potential application fields are chemistry, microbiology, food industry and agriculture. The system is easy-to-operate, reliable, and is based on simple hardware.


Selivanova Z.M. Intelligent measuring probe for nondestructive check of solidsí thermophysical properties
An intelligent measuring probe is presented. The probe eliminates the effects of external factors and adapts to objectís thermal exposure intensity. This increases the speed and accuracy of nondestructive check of solidsí thermophysical properties.


Serebrykov D.I. Temperature error reduction for a fiber-optic liquid level relay
The paper suggests to introduce an additional optical compensation channel in a liquid level sensor to reduce its temperature error.


Setchenkov M.S., Sharafutdinova R.R., Nasibullin R.S. On the modernization of TESLA BS 567A spectrometer
A sensitivity improvement technique for BS 567A nuclear magnetic resonance spectrometer is offered. Sequential summation of digitized points over the time interval smaller than spectrometer frequency scan is used.


Loktyukhin V.N., Chelobaev S.V. Principles of artificial neuron networks application in signal-to-code converter design
The opportunity is justified and principles are determined of applying artificial neuron network techniques in the design of analog-to digital converters of time-and-frequency parameters of sensor signals. With the example of perceptron learning, the paper shows the design of mathematical models for the frequency and time interval to code converter structures.
