💦 Travelling Irrigator Quick Check v1.0.0
Calibration check following the IrrigationNZ Code of Practice Part F, 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.
22 containers with the same known opening (over 150 mm; 9 litre buckets work well) in a line across the run, at right angles to the hose or cable. L11 and R11 go half way between the lane edge and the edge of wetting; L10 and R10 the same distance inside the lane edges; L1–L9 and R1–R9 evenly back to the centre line.
If the wetted width is no more than the run width there is no overlap: L11 and R11 are left out and ten buckets are spread across each side. Set Out Collectors fills in suggested distances; replace them with the actual distances if they differ. Record each volume against the correct position.
Put a marker flag beside the hose or cable at least 5 m either side of the bucket line, visible from outside the wetted area. Time the gun cart or boom between the flags.
What is calculated
- Irrigator speed and time for each run
- Applied depth after adding the overlap buckets
- Distribution uniformity and the excess water use factor
- Application intensity, and flow worked out from the buckets
- The speed to apply your target depth to 7/8 of the area
