Calibrating the flow meter
When should you calibrate?
Because the number of pulses per liter can change during the lifespan of a flow meter, calibration must be carried out in the following cases:
- ▪
- Prior to initial start-up.
- ▪
- At the start of each season.
- ▪
- When you detect deviations between the quantity actually sprayed and the quantity displayed.
- ▪
- When you have replaced or repaired the flow meter.
Methods
There are two ways you can calibrate the flow meter:
- ▪
- The tank method – it is time-consuming, but precise.
- ▪
- The nozzle method – it is not as precise as the tank method, but is less time-consuming.
