FEATURES

  • Keep tongue weight within the hitch and vehicle’s rated capacities.
  • Compare tongue weight to trailer weight to verify trailer is properly loaded.  Tongue Weight should be around 10-15% of Gross Trailer Weight (weight of trailer and cargo).
  • Save money on expensive tongue weight gauges
  • Convenient. No more hassle of using a bathroom scale to find tongue weight.
  • Safety. Proper tongue weight is key to safe towing and trailer sway avoidance. Use HaulGauge to get it right and tow safe.

HOW TO CALIBRATE TONGUE WEIGHT

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.

HOW DOES IT WORK?

HaulGauge measures weight by monitoring powertrain effort and vehicle acceleration.  Powertrain effort is calculated from a torque converter model.  HaulGauge uses the VIN to search its database for the correct torque converter calibration.   If HaulGauge doesn’t find a calibration within its database, the user may calibrate the scale utilizing a patented machine learning algorithm.  Acceleration is determined utilizing a triaxial accelerometer on board HaulGauge.   When powertrain effort is high relative to vehicle acceleration, then weight has increased.
