K-factor analysis is used in our facility in lieu of a plain +/- 3-sigma tolerance interval. , Does Wittenberg have a strong Pre-Health professions program? The K factor relates the metabolite signal to that obtained from tissue water, i.e., the procedure uses tissue water as an internal calibration standard. Any in SPE Disciplines (8) Journal. To calculate the correction factor, just subtract the UUC reading from the Nominal Value (STD-UUC). The totalizer K-factor in example 3 will be = 5 x 60 = 300 in order to totalize in gallons. K-Factors are calibration values (pulses per unit of volume) used to convert flow sensor . The calibration procedure used to determine the actual reference volume of the small volume prover. Needs to be an exact divisor of the K-factor Range (End - Start), Distance between the test lines. The equation is as follows: C = Q / (change in temperature). Once the meter factor is determined it is used as a volume correction in the calculation for net standard volume of a receipt or delivery of liquids. What is meant by the competitive environment? Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Similarly, k=3 means a really high confidence value that 99.7% readings would lie within three standard deviations of the mean. K-Factor A constant determined by dividing the thickness of the sheet by the location of the neutral axis, which is the part of sheet metal that does not change length. The device has unmatched capability of precise and repeatable K-Factor generation based on the turning of the balanced rotor and the subsequently generated frequency pulse signal via the magnetic coil assembly, providing accuracy of +/-.15% with special calibration applied.
