Abstract
The system of automatic chemical solution metering, used in urban water and wastewater treatment plants, is considered in the article. A functional diagram is proposed; simulation of Bessel filter of the third kind and Butterworth filters of the second and third kinds to rectify the signal is performed.
Keywords
automatic metering, noise, optimal filter
