OPTION NO 2
This would be to fit an airbag pressure gauge to the airbag line and use pressure readings to indicate the load.Typically the unladen pressure would be marked on the gauge.
Then the truck or trailer would be loaded up to capacity load.
There after the truck or trailer would be weighed on the weighbridge and the pressure marked on the gauge. This would always indicate full load.
Half load would be determined by dividing the point between "no load" and "full load".
This method is the same as the above, just does not have the fancy enclosure or gauge.
