In many cases, the reasons canbe determined in this way and faults rectified.The below tables show typical examples of application-relatedmeasurement errors with bulk solids. A distinction is made betweenmeasurement errors during:• Constant levelReaction when malfunc-tion occursProcedure for fault recti-ficationTreatment of measure-ment errors with bulksolids
