Flow Sensor Wiring
The Series 3050 flow sensor inputs are extremely versatile, designed to accept either two-wire or three-wire pulse inputs
(Data Industrial 200 Series, SDI or 4000 Series) or Analog inputs. Although different rear panel terminals are used, all
parameters are set with the LCD/keypad interface. There are no internal or external jumpers, switches or potentiometers to
move or adjust.
The following pulse input types are accommodated.
• Pulse-DI: Used for all Badger Meter Data Industrial Flow Sensors. Provides an internal pull-up resistor and uses “K”
and “Offset” values for calibration.
• Pulse–K Factor: Accepts non zero-crossing inputs but provides no internal pull-up, classical “K” ( pulses/gallon)
values for calibration.
• Pull-up-K Factor: Provides an internal pull-up resistor and uses classical “K” ( pulses/gallon) values for calibration.
NOTE: All the above pulse input types wire the same as shown in Figure 4. See the Programming Flow Chart on
page 18 for required input configuration.
