Magnetic flowmeter for sodium-cooled fast reactors

The magnetic flowmeter for liquid sodiumis described, in which inductor represents the electromagnet generating a pulse low-frequency magnetic field. The application of the pulsed magnetic field has allowed to separate the informative component of a signal from all hindrances of the electromagnetic origin, for which the frequencies of change in time are not multiple to the frequency of change of a magnetic field of excitation. Thanks to it accuracy of a flow measurement is essentially increased, and there is a possibility to lower in 10 times a magnetic field in the channel. The physical principles of the measurement method, the design features of the flowmeter IRMU-1, its specifications and test results are considered.

Keywords: ia magnetic flowmeter, inductor, liquid sodium, a pulse low-frequency magnetic field, Reynolds's magnetic number.

Fundamentals of weighing systems using an effect of inclined plane

Represents substantiation of the physical processes accompanying the creation of weighing systems, alternative to the usual platform variants, comparable to them on accuracy. Considers the laws of friction of sliding and rolling, the rational use of which allows to minimize their negative impact on accuracy measures, and to create the competitive weighing systems, not having analogs in relevant technical annex.

Keywords: weighing system, inclined plane, friction coefficient, tractive effort, skating force (climbing resistance), friction force, measuring process, measurement fault.

Synthesis of instruments and systems minimum duration criterion transition process

Point and integral estimates of the duration of the transition process for test signals of various shapes are considered: stepped, linearly expanding, pulsed and harmonic. Recommendations are given on the calculation of optimal values of the parameters of the transfer function of the dynamic system by the criterion of the minimum duration of the transient process.

Keywords: duration of the transient process, measuring device, synthesis.
