22 22 Sentry COS Operation, continued Performance Factor Calculations There are two performance factors calculated by the COS controller: Can and Batch. Can performance factor is based on the expected sample volume for the current can versus the actual sample volume of the can. The can PF value calculation is based on total can weight since the last tare. CanPF = AccumulatedCanSampleVolume CalculatedCanSampleVolume The accumulated can sample volume is the actual volume collected for the can so far, where AccumulatedCanSampleVolume = AccumulatedCanSampleWeight MeanCanDensityinput The calculated can sample volume is the theoretical sample volume collected so far, where CalculatedCanSampleVolume = BatchVolumeThisCan x RequiredSampleVolume RequiredBatchVolume - BatchVolumeUptoPreviousCan Batch performance factor is based on the expected sample volume for the total batch processes so far versus the actual sample volume for the batch. This performance factor corresponds to the ANSI/ASTM D4177 standard. To get a batch PF calculation, you must tare the can between batches. BatchPF = AccumulatedBatchSampleVolume CalculatedBatchSampleVolume The accumulated batch sample volume is the actual volume collected so far, where AccumulatedBatchSampleVolume = AccumulatedBatchSampleWeight MeanDensityinput The calculated batch sample volume is the theoretical sample volume collected so far, where CalculatedBatchSampleVolume = MeasuredBatchVolume x RequiredSampleVolume RequiredBatchVolume
