Development of battery – driven electromagnetic flow converter
The mean parameter of battery-driven electromagnetic flow converter s is power consumption. Stronger signal, when magnetic field is the same, could be obtained, using channel of rectangular cross-section with wide electrodes. Magnetic circuit should be designed in the way that transmission coefficient would be as big as possible. Power consumption can be reduced, decreasing relative measurement interval and excitation current, but the parasitic signals shows up. Effectiveness of filtration of every pulse of electrode signal must be maximal. To heave a mean the composition of noise of signal, for filtering the best variant is Wavelet filters. During the examination, there was determined that the best is to use 4-leveled sets of filters. Ill. 11, bibl. 4 (in English; summaries in English, Russian and Lithuanian).
