Station calibration following the IrrigationNZ Code of Practice Part C, Section 2
Save everything entered on all tabs, plus the results, to a CSV file on your computer. Load it later to fill the tool back in and recalculate.
With the system running. These help find the cause of poor results; they are not used to calculate flows.
A station is the area controlled by one valve. In each station collect water from one emitter at the beginning, middle and end of the lateral nearest the inlet, two middle laterals and the lateral furthest from the inlet: 12 samples. Collect for at least 5 minutes or 250 mL.
Pressures (optional) at the beginning, middle and end of the first and last laterals, and at the station off-take, help explain poor results.
What is calculated
- For each station: mean emitter flow, application rate, applied depth, emission uniformity and an adjusted run time for the target depth
- Field uniformity across all stations, and with run times matched
- Pressure and flow patterns that point to likely causes of poor results
