(for all ILR models with display)
Unit of measure & scale factor programming
1. Press and release the RESET button to change the unit of measure (L, GAL, QT, PT).
2. Press and release the TOTAL button to select desired the unit of measure (the selected unit of measure will flash).
3. When the appropriate unit of measure is selected, press the TOTAL button to advance to the scale factor programming.
3.2 Scale factor
(for all ILR models with display)
The register collects input pulses from the oval gear meter and then determines the appropriate display output using the
scale factor. This scale factor varies depending upon the viscosity of the liquid being measured, therefore calibrating the
meter and register in the appropriate liquid will affect the scale factor. The scale factor is displayed as 5 digits (on the top row)
next to the unit of measure. The scale factor consists of 1 integer digit and 4 decimal digits.
1. Press the TOTAL button to select a digit (selected digits flash). After cycling through all 5 digits of the scale factor, the
register will return to the unit of measure selection.
2. Press RESET to change the selected digit. The scale factor must fall between the values of 0.5000 and 2.0000. The Badger
Meter factory preset is set between those values at 1.0000.
3. When finished adjusting the unit of measure and scale factor, press and hold the TOTAL button for one second to advance
to the Pulse Rate section.
NOTE: Error checking will not allow the user to advance to the next screen.

3.3 Changing the meter pulse rate (for all ILR models with display)
The meter pulse rate (screen is indicated by the “I” on the top row, on the left side) is the number of pulses per unit of measure
as detected by the register. The pulse rate varies according to the type of attached meter. The bottom row consists of the 5-
digit integer value of the meter pulse rate, whereas the top row consists of the 2-digit decimal value of the meter pulse rate.
The meter pulse rate is entered in pulses per liter if the selected unit of measure is liters. The meter pulse rate is entered in
pulses per gallon if the selected unit of measure is gallons, quarts or pints.
Meter Pulse Rate
1. Press the TOTAL button to select a digit (selected digits flash). Press RESET to change the selected digit. The pulse rate can
be any value between 00000.01 and 99999.99 on the top row; integer values are displayed on the bottom row. Example:
10.45 would display .45 on the top row and 10 would be displayed on the bottom row.
2. When finished adjusting the pulse rate, press and hold the TOTAL button for one second to advance to the “register
orientation” section.
NOTE: Error checking will not allow the user to advance to the next screen.
3.4 Changing the register orientation (for all ILR models with display)

4. ADDITIONAL PROGRAMMING: INDUSTRIAL ANALOG AND INDUSTRIAL PULSE (ILR750, ILR750T, ILR701,
ILR701T)
Output pulse lenght
(for models ILR750 and ILR750T)
Indicated by a “P” on the left hand side of the display, this screen allows the selection of the low duration of the output pulse.
•“0” for zero milliseconds (pulse output is disabled)
•“2” for 2 milliseconds
•“10” for 10 milliseconds
•“20” for 20 milliseconds
•“40” for 40 milliseconds
•“100” for 100 milliseconds
To advance to the next programming screen, hold the TOTAL button.
Output pulse lenght screen
About Output Pulse Length: The pulse rate duration should take into account the "Pulse Rate Out" and maximum meter
flow rate, to prevent an output pulse duration greater than the required time between pulses. The Output Pulse Length
should be set to less than the value of “t.”
Per the equation:
Maximum meter flow rate (in GPM or l/m)
t = ----------------------------------------------------------------- x 1000
60X output pulse rate
where t = the required pulse rate in milliseconds.
The output pulse rate = the programmed parameter (default = 1.00 PPL/PPG)
The maximum meter flow rate = the maximum flow rate of the meter for the application.
