Frequently Asked Questions

How does iWeigh® work?
iWeigh® uses sensors to measure air pressure (for air ride suspensions) or a highly-engineered deflection sensor to measure micro-flexing of the axle group (for mechanical suspensions). By calibrating the system with known empty weight at time of the and known loaded weight, iWeigh® uses the saved calibrated data to accurately calculate and display the current weight of the vehicle.

The scale must be calibrated before use. iWeigh® can display weights in pounds or kilograms.

After calibration, simply view weights on the Air-Weigh app or through telematics. The weight data will update in real time.
