The threshold Čerenkov counter based on dense aerogel with refraction index $n=$1.13 is described. This counter is used for $\pi/K$ separation at SND detector at VEPP-2000 $e^+e^-$ collider in the particle energy range up to 1 GeV. The results on separation efficiency for hadrons produced in $e^+e^-$ annihilation are presented. New results on the $e^+e^-\to K^+K^-$ process cross section has been obtained in the energy range $1.05\div 2.0$ GeV with using the Čerenkov counters. The cross section value was found to be consistent with previous measurements.
