Only 2% accurate, but the calibration factor specified as 7.5hz/(l/min)=450pulses/liter seems to be quite off as well. After averaging a couple of tests, I've calculated it to be more like 13.25hz/(l/min) = 796 pulses/liter.
Seems to report relatively accurate flow.
Exactly what I was looking for, and worked perfectly. Just as advertised.
