    A belt scale is a load cell that is mounted to a conveyor idler or idler (s) and measures the downward force of the material. Calibrating with a known belt speed or using a speed sensor on the belt, the integrator both calculates the instantaneous rate and total. Belt scales can provide to 1% accuracy’s on belts ranging from 18” to 60
