Using the MASStrol as an example the K-factors would be programmed as follows. It represents how many frequency signals per cube. Turbine oil. Its because the calorimeters are different, so the amount of heat lost to the environment is different. K-factor Calibration Pattern Caution! The correction factor in a measured value retains its importance in properly evaluating and investigating the veracity of an experimental result. The electronic device continuously divides the incoming pulses by the K-Factor, or multiplies them with the inverse of the K-Factor, to provide factored totalization, rate indication, and various outputs. Calibration in analytical chemistry is important because it is a way to ensure that equipment and reagents are uncontaminated and behaving as they should. The totalizer K-factor will be 500 x 1/0.001 = 500000. This K-factor will be given in terms of the number of pulses produced by the meter for a given volumetric flow.
