Abstract
An apparatus and method are provided in order to verify the calibration on the fluid handling system. A magnet coupled to the scale is used to attach a precalibrated weight so that a controller in the system can determine if the scale needs to be calibrated. This way a storage tank does not need to be removed in order to check the calibration of the scale. The system can be locked down if the calibration is not within the predetermined calibration tolerance.
