Software Scales are installed in the motor starter of the conveyor.  They take the motor amperage and convert it to tonnes per hour.  There are no moving parts, no mechanical parts, nothing installed on conveyor.  Scales are calibrated to a known weight that transfers over the belt, no test weights are used.  Only requirements are an incline on the conveyor, a reasonable load on conveyor in relation to motor horsepower.  Scale accuracy is easily within 1%.  Scales can also include an angle finder and will work on Telescopic Conveyors
