RESEARCH OF LONG-TERM DRIFT OF THE NATIONAL INDUCTANCE STANDARD

Inductance measurements is important for all branches of technology related to the application of electricity: energy
and electronics, radio and television, transport and communication, and scientific research. Electromechanical devices and
electronic components can be characterized using impedance measurements to identify the parameters of their equivalent electrical
model. New inductance measurement methods are being developed in specific fields of activity. Manufacturers of standards and

Auto calibration method of periodic device for measuring the pressure drop variable costs

The method of periodic auto-calibration a device for measuring the flow of alternating pressure drop directly in terms of their operation, which are widely used in various industrial sectors for the control and accounting costs of various liquid substances (oil, hot water, food, etc.). The basis of the method is based on the use of structural and temporal redundancy measurement conversions, enabling algorithmic way to identify and consider an amendment to the progressive flow errors as additive and multiplicative nature.
