POSITIONING THE SENSOR IN SAMPLING FLOWMETERS
Journal Title: Metrology and Measurement Systems - Year 2008, Vol 15, Issue 1
Abstract
Flow-rate measurements have very important meanings in industry. The sampling flowmeters are devices which can be used for measuring the flow-rate in situations where full-bore flowmeters cannot be used for technical or economical reasons. The main problem in the flow-rate measurement with the help of sampling flowmeters is optimal positioning of the sensor in the pipe. When we use a mathematical model of a sensor and a mathematical model of an object, we can theoretically optimize the position of the sensor in the pipe.

A METHOD OF IDENTIFICATION OF RTS COMPONENTS IN NOISE SIGNALS
Noise signals containing two components with different distribution of current values of the noise signal, i.e. a component with Gaussian distribution and a component with non-Gaussian distribution, were analyzed. The no...
APPLICATION OF SOM IN CLASSIFICATION OF EGG SIGNALS
The report presents problems associated with computer aided gastric diagnosis. The subject of the study are electrogastrographic (EGG) signals (non-invasively measured electrical signals generated by the human stomach)....
REVISING THE SI: THE JOULE TO REPLACE THE KELVIN AS A BASE UNIT
The joule is proposed to replace the kelvin in the set of SI base units. Arguments in favour of such replacement are presented, including improved standard accuracy and unit system coherence. The joule is also proposed t...
MEASUREMENTS OF UNSTEADY FLOW PARAMETERS IN PIPE-RECEIVER AND PIPE-TURBOCHARGER SYSTEMS
In the paper, the characteristic features of an unsteady flow in two systems: a high-volume pipe-receiver and a pipe-turbine are described. The tests were made under the conditions of a pulsating pipe supply in the range...
