A system and method for calculating the weight of a load over a conveyor belt system. The method comprises placing a material that has a weight onto a conveyor belt, moving the conveyor belt at a desired speed, and calibrating a weight meter to solve for the coefficients of a polynomial equation. The method then comprises operating the motor drive to send a desired power supply signal to the motor. The motor drive sends command signals to the motor to move the conveyor belt at the desired speed. The weight meter inputs the power supply and speed signal data as well as the coefficients calculated in the calibration into a polynomial regression formula to calculate for the mass of a load on the conveyor belt in which mass is a function of the power and speed. The weight meter outputs the mass calculation to the other system components. |
