Resonant scanning circuit sweeps 0-10KHz to find lock, with 8-20% variance from contaminants
The resonant scanning circuit (Figure 8) scans frequency from high to low to high, e.g. 0 Hz to 10 KHz to 0 Hz, until signal lock; water contaminants of 1-20 ppm cause about 20% variance in resonant frequency, while normal water flow variance is about 8-10%.
