Aiming at the characteristics of fast flow and high volatility of dense phase powder, the basic method of processing the powder flow signal by using the least mean square error LMS adaptive filter is firstly studied. The spatial filter effect of the capacitive sensor is studied first, and then the pulse is estimated by LMS criterion Response function, accurate peak-seeking, can overcome the impact of convolution and smearing method.Finally, the results of the actual measurement signal processing.
