typically 6000 pulses / liter (mine is 6150 though)

so if your SF80 is 6000 pulses = 1L

100 Hz = 100 pulses/sec = 1LPM

if i remember it correctly the mid wire is for RPM

if you are going to hook it up to a CF633 type thingie with PPR=1 simply dividing the reading by 6000 gives you LPM

if you are hooking it up to a fan header on a mobo, divide the reading by 3000. or use Fan Type /3 in MBM5
mobo headers use divider /2 AFAIK
