HOW DOES IT WORK?
Accelerometers on board HaulGauge measure the change in pitch as weight is loaded onto the trailer. HaulGauge uses the VIN to search its database for the correct suspension calibration. With vehicle pitch and suspension coefficient, the tongue weight may be calculated in real time. If HaulGauge doesn’t find a suspension calibration within its database, the user may calibrate the scale using their own weight as a reference.
