TowSense™ technology is a digital towing scale system. Using an accelerometer circuit, TowSense™ measures changes in the velocity and pitch of your vehicle. It uses this data to calculate weights associated with towing and hauling.

Armed with TowSense™ technology, BetterWeigh™ wirelessly connects to your Apple or Android phone to display the weight of the vehicle, trailer, cargo / payload, tongue weight, pin weight, weight distribution and trailer brake gain.

How It Works

CURT BetterWeigh - How It Works Equation

Newton’s Second Law of Motion states that force equals mass multiplied by acceleration. Force is determined by measuring slip across the torque converter as the vehicle accelerates. Acceleration is determined by an onboard accelerometer.

BetterWeigh™ uses these properties to calculate the weight of your vehicle, trailer, cargo and more. With the unit calibrated, it can measure real-time weight while driving or at a standstill, and at any upward or downward grade.
