A system for measuring a conveyor belt includes a first detector fixed at a location along a path of a conveyor belt. A first signal generator is affixed at a first location of the conveyor belt such that the first signal generator is detectable by the first detector when the first signal generator is in range of the first detector. The first detector is configured to provide a first signal as the first signal generator approaches the first detector. The first detector is configured to provide a second signal as the first signal generator moves away from the first detector. A processor is in electronic communication with the first detector and configured to calculate a belt speed based on an elapsed time between the first signal and the second signal.

A method for estimating the weight of loads carried by implements may include controlling an implement subject to actual weighing conditions to lift a load and receiving an input indicative of a sensed force associated with lifting the load. The method may further include determining a correlation value indicative of a correlation between first and second force values for lifting a given load with the implement as a function of the actual weighing conditions and as a function of nominal weighing conditions, respectively, where at least one of the actual weighing conditions differs from at least one of the nominal weighing conditions. Furthermore, the method may include determining an adjusted force value for lifting the load based at least in part on the sensed force and the correlation value. Additionally, the method may include estimating the weight of the load based at least in part on the adjusted force value.
