The K-factor is the frequency divided by the flow rate => [1/s] / [g/s] = 1/g. The meter factor is obtained by dividing the prover test volume by the indicated volume of the meter. 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. Turbine flow meter is the most popular equipment to measure flow electronically. This should differ noticeably from Slow Speed, Set the Jerk for the X-axis. The coverage factor, or k value, determines the confidence in the data points within a certain standard deviation value. Per the Guide to the Expression of Uncertainty in Measurement (GUM), the expanded uncertainty is a measure of uncertainty that defines an interval about the measurement result within which the value of the measurand can be confidently asserted to lie. the slope of the line between the response for .

Which of the Balearic Islands is the best to visit? Professional Partner for Measure & Control. Calibrating them takes this difference in heat loss into account, thus ensuring that the calculations are based entirely on the substance being tested. Compressor oil. The 16 point K-factor would be programmed as follows. For k=1, there is a confidence that 68% of data points lie within one standard deviation, while k=2 means a confidence that 95% of the data points would lie within two standard deviations. Different Types of Flowmeters Technical and Application Analysis. Verify it using a host software like. What is the difference between K factor and meter factor? K-factor is a coefficient calculated by calibrating and comparing with other measuring devices that meet the accuracy requirements. The K-factor is then calculated by relating the engineering unit equivalent of 20 mA to the 10000 Hz. A firms capital requirement is the higher of its permanent minimum capital, its fixed overhead requirement, or its K-factor requirement. Therefore, this frequency of the pulse output is proportional to the rate of the flow. Simply stated a K-factor is a dividing factor.
