The term is usually encountered when dealing with pulse signals although analog K-factors are sometimes used. The meter factor is obtained by dividing the prover test volume by the indicated volume of the meter. Eliminating or minimizing factors that cause inaccurate measurements is a fundamental aspect of instrumentation design. Your Bowden should be higher, but the value might be . Calibration is a comparison between a known measurement (the standard) and the measurement using your instrument. The totalizer K-factor will be 500 x 1/0.001 = 500000. K factor uses the formula K factor = /T. QQ: 1833768980 The K-factor comes from the ratio of the neutral radius divided by the thickness of the material on prepared charts and has a value between 0.3 and 0.5. This activity requires that a comparison is made between a known reference measurement (the standard equipment), and the measurement using your instrument (test instrument). How do you calculate Cal factor? It is the actual coefficient obtained by the flowmeter manufacturer after verifying each instrument. One of the advantages of the in-line meter is that it does not require as much straight run as the insertion-style meter. A total uncertainty budget is calculated from these uncertainty values for each measurement point, and that is what is presented in this column of the certificate.
