Identification of the calibration procedure used. K-Factors are calibration values (pulses per unit of volume) used to convert flow sensor . The second step is to relate an incoming frequency range from the flow meter to a given calculated K-factor. Some flow applications dictate that multiple K-factors are used. Each calibration or response factor represents the slope of the line between the response for a given standard and the origin. The thermal mass flow meter is a meter that uses the principle of heat transfer. Note also that as the last two K-factors are the same any flow above 100 gpm will be modified by a K-factor of 104. Load Cell Calibration is an adjustment or set of corrections that are performed on a load cell, or instrument (amplifier), to make sure that the sensor operates as accurately, or error-free, as possible. In analytical chemistry, calibration is defined as the process of assessment and refinement of the accuracy and precision of a method, and particularly the associated measuring equipment (i.e., an instrument), employed for the quantitative determination of a sought-after analyte [2]. 1) The K-Factor is not always consistent across the entire flow rate measurement range.
