. The value of the totalizer K-factor will depend on whether the flow rate was given in units per second, minute or hour and whether it is desired to totalize in whole units, tenths, hundredths etc. -. In vortex flowmeter, the relationship between flow rate and the number of vortexes generatedcan be expressed by the following formula. What is the difference between K factor and meter factor? How to Choose? It is the actual coefficient obtained by the flowmeter manufacturer after verifying each instrument. Required fields are marked *. The industry-accepted formula for assay on anhydrous basis = (assay on as-is basis100)/(100-%water). Use the equation Q = C x (change in temperature when a substance is burned in the calorimeter). This website uses cookies to improve your experience while you navigate through the website. for UBL) before printing. If the flow rate was given in units per second the totalizer K-factor (for whole units) is obtained by multiplying the rate K-factor by 1. Two applications that require multiple K-factors are: Some Flow meters have an option available that allows the user to input from 3 to 16 K-factors. 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. Because the blades of the impeller have a certain angle with the flow direction. Cal Factor = (amt of drug in mg) / (cc solution) / (60 min/hr). The process of calibration involves configuring an instrument to provide sample measurement results within an acceptable range.

What is a K-factor Simply stated a K-factor is a dividing factor. It can be transmitted to the display instrument remotely. This is known as the calibration factor of the calorimeter. 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. A continuous rectangular pulse wave with a certain amplitude is formed. On a practical level, this means that if you were to make 100 measurements, you could be confident that (at least) 95 of them would be accurate to within the stated uncertainty. The Flow Meter K-factor will be confirmed before it is put into use. Why Orifice Flow Meter Flange is not Recommended 150# Rating ? Caution! This K-factor is the value that is entered into a batch meter or indicator/totalizer in order to give a readout in engineering units. Compressor oil. 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. Put in the simplest of terms, K-Factor is no more complicated than understanding that the meter will generate a specific number of pulses for every unit of product passing through it. This process of evaluating factors that lead to uncertainty in measurement results is known as uncertainty evaluation or error analysis. The second step is to relate an incoming flow value from the flow meter to a given calculated K-factor. Home Flow Measurement Solutions What is Flow Meter K-factor?

Transit Time Flow Meter Advantages and Disadvantages, Reasons to Calibrate Different Types of Flow Meters, What is a Torbar? Calibration Uncertainty: Again, as with prediction, the data used to fit the process model can also be used to determine the uncertainty in the calibration. K-Factors are calibration values (pulses per unit of volume) used to convert flow sensor output frequencies to flow rates. month, every month the meters are left uncorrected. Maybe you've received a calibration certificate for your instrument and noticed that it mentions something like "reported at k=2" at the bottom of the certificate? Each of the standards used in the calibration (as listed in the "Measurement Standards Used in Calibration" section of the certificate) has uncertainty associated with their specification. The coverage factor, or k value, determines the confidence in the data points within a certain standard deviation value. A turbine flow meter has the following calibration data. The calibration is accomplished using a reaction with a known q, such as a measured quantity of benzoic acid ignited by a spark from a nickel fuse wire that is weighed before and after the reaction. Calibrating them takes this difference in heat loss into account, thus ensuring that the calculations are based entirely on the substance being tested. The totalizer K-factor in example 3 will be = 5 x 60 = 300 in order to totalize in gallons. Usually, there will be an option called Span Calibration. Calibration.
