Menu 3.5 Tank gauge
General info
This menu item is only present, if the HARDI Tank Gauge is fitted. For increased accuracy, it is recommended to do the flow
calibration before proceeding. See menu [3.2.3 Tank method].
The tank content is measured from the bottom of the main tank using a fluid pressure sensor.
The accuracy is affected of the sprayer being level. Assume that if the sprayer’s hitch point height measured from the ground
is 550 mm, then the readout of tank contents changes with the height of the sprayer at the hitch point. Also when driving
on uneven or sloping ground, the readout will vary, as the fluid pressure changes above the sensor.
If the tank gauge is replaced, it must be recalibrated.
Menu 3.5.1 Adjustment
The correction factor for the specific gravity of the liquid sprayed can be
set.
÷
NOTE! Default value is 1.000.
For liquid fertilizers, the density is often higher than for water mixed with
pesticides, and the specific gravity (or density) might be 1.3 kg/litre. The
value in this case would be 1.300.
