 Scaled pulse

 Impulse parameters DFM fuel flow meters
 DFM-50 360 ms  18000 ms  5 ml/pulse
 DFM-100 180 ms  9000 ms  5 ml/pulse
 DFM-100D 200 ms  36000 ms  5 ml/pulse
 DFM-250 180 ms  9000 ms  12.5 ml/pulse
 DFM-250D 200 ms 90000 ms  12.5 ml/pulse
 DFM-500 144 ms  7200 ms  20 ml/pulse
 DFM-500D 180 ms 144000 ms  20 ml/pulse

Uhigh= U supply (Ubattery)

Ulow= 0.7V

tlow= 80 ms

if one takes the model DFM-250, the highest flow is 60 seconds x 60 minutes / 180 ms = 20.000 pulses per hour = 250 l/h
