How to fix Badger Meter Controller when flow meter generates too many pulses?
- C
  christinahudsonAug 9, 2025
  If the flow meter is generating too many pulses, verify the settings for Total and Flow Rate. Also, check the type of signal selected against the actual signal generated, and inspect the sensitivity of the coil input. Ensure the ER-420 is properly grounded. Use shielded wire for flowmeter signals and connect the screen to terminal 9, unless it's already connected at the sensor.
