Frequency Converter HiD2891
If the value should be displayed in l/min, l/h or m³/h, m/s or km/h, the number of input pulses per
liter, per m³, km or m must be entered (see Divider parameter). Then the units are converted as
follows:
Hz x 60
l/min =
Pulses per liter
Hz x 3600
l/h =
Pulses per liter
Hz x 3600
m³/h =
Pulses per m³
Hz x 1000
m/s =
Pulses per km
Hz x 3600
km/h =
Pulses per km
• Smoothing:
If values deviate sharply, smoothing can affect how quickly an output responds to a change in an
input value:
− 0 s = no smoothing
− 255 s = maximum smoothing
• Divider:
The Pulse/unit menu item only appears if you have selected a unit other than Hz for the value
display (see Unit parameter).
Enter the number of pulses per revolution, per liter, per m³ or per km, depending on the selected
unit. The conversion is performed as described in the Unit parameter.
