Build & Run a Learned Flow Program

"Learning flow" is a crucial step for any site utilizing a flow sensor on a smart controller. A Learned Flow program calibrates true flow rate at the station level by running one station at a time & recording measured flow rate for each station. These measurements set a stable foundation for flow deviation alerts & consumptive flow measurement. 

In the NLP, Learned Flow programs can be built like a standard program & include any number of stations. During a Learned Flow, the NLP automatically senses when flow has stabilized at a given station, reducing overall learned flow run time & flagging specific flow issues. 

Note: A Learned Flow Program must be completed when using low/high deviation flow alarms. It is recommended to Run a Learned Flow Program at least yearly to correctly calibrate expected flow rates. For sites with multiple mainlines, the NLP will allow irrigation during a Learned Flow Program if there are multiple mainlines.

1. Navigate to   → Irrigation Controller → Programs
2. Click
3. Under Strategy dropdown, select Sequential
4. Under Description, enter “Learned Flow Program”
5. Click CREATE
6. Click STEPS
7. Click
8. Under Target type dropdown, select All and under Type dropdown, select Learn Flow
9. Click Wait completion to toggle to
10. Click CREATE
11. Click SAVE
12. Click  next to your new learned flow program to run
13. Once the Learned Flow Program is complete, go to Stations → 
14. Under the Station Actions dropdown, select action Apply observed (learned) flow →  SAVE.

You can now see the new calibrated flow values as Expected flow. If you disagree with any of the Learned Flow values, manually update Expected flow by editing a station.
