Application of Coriolis mass flow meters for gas-liquid mixture flow measurement

In this article a method of testing flow meters using gas-liquid mixtures is described. There are results of coriolis mass flowmeter testing in the article. A method of using calibrating curve based on volume content of gas in a fluid is suggested, as well as the results of this method realisation are described. The article contains a measurement method which uses both mass and density measurement possibilities of the mass flowmeter. This method allows to optimise metrological characteristics of the device, improves its reliability and provides self-diagnostic possibilities.

Keywords: flow meter, mass flowmeter, multyphase flow, crude oil, free gas.

Modification of the frequency-domain stability criteria in order to give them new useful properties

The modified frequency-domain stability criteria that have useful new properties are formulated. One of the basic properties of modified criteria is capability of finding through them the parameters of the stabilizing device. Examples of stabilization of unstable non-minimum-phase plants which are of the order of less than ten by the first-order controller are presented.

Keywords: stability criterion, control systems, modification of criteria, criterion of Najkvista, criterion of Mihajlova, indirect estimations, frequency criteria.

Diagnostics of the state of polymeric materials on the basis of their analysis electromagnetic fluctuations

The method of definition of physical performances of polymeric materials on the basis of meas-uring and the analysis of their electromagnetic fluctuations is viewed. Questions of reception of the measuring information are analysed, mathematical models, both the most polymeric system, and the primary measuring transformer with the explored material, working as a part of measur-ing installation are presented. Questions of adequacy of systems polymeric medium and polymeric medium the primary transformer are explored, preferential frequencies for carry-ing out of measuring of the dielectric, mechanical, thermal performances are revealed.

Keywords: polymeric materials, electromagnetic fluctuations, state diagnostics, the measuring information, physical performances of polymeric materials.

Problems in creating effective film thermoelectric converters and their solutions

In paper three basic questions related with metrological assurance of temperature sensors made of platinum and platinum-rhodium wire manufacturing are considered. The questions are: practical use of wire W100 parameter, estimation of wire unheterogenity in thermo-emf, current definition of nominal state characteristic for type S thermoelectric transducer. Authors describe current state of affairs in area under consideration and offer ways of elimination of inconsistency in wire manufacturers and consumers standards. The paper in many respects based on results of Siberian State Institute for Metrology (Novosibirsk) and JSC Krastsvetmet (Krasnoyarsk) joint researches. The characteristics of methods and instruments recently used by JSC Krastsvetmet to control platinum and platinum-rhodium wire parameters are given. Its shown that reached reliability of the control is sufficient. The attention to possible necessity of redefining of nominal state characteristic for type S thermoelectric transducer is paid.

Keywords: converter, efficiency, thin films, properties, parameter, control, mode.
