The pulse specifications for using our (models A-K, D and C-K) fuel flow meters with a remote readout unit are specified below.

Model	Timp min	Timp max	Scaled pulse
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

U_high= U _supply (U_battery)

U_low= 0.7V

t_low= 80 ms

Example: 
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
