The K-Factor is determined using a flow lab calibration. Extended Reading: Magnetic Battery Operated Flow Meter. The K-factor is then calculated by relating the engineering unit equivalent of 20 mA to the 10000 Hz. The correction factor is reciprocal of the response factor2. The second step is to relate an incoming flow value from the flow meter to a given calculated K-factor. The Flow Meter K-factor is given by the manufacturer when it is calibrated. The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated Calibration Range The zero value is the lower end of the range or LRV and the upper range value is the URV.

A calibration procedure is a controlled document that provides a validated method for evaluating and verifying the essential performance characteristics, specifications, or tolerances for a model of measuring or testing equipment. We promise not to spam you. I cant remember what mine is set to, but if I recall it's set to something that I thought would be absurdly low (like 0.08 i think?). Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Use the equation of the calibration curve to adjust measurements taken on samples with unknown values. An alternative to using the manufacturers data is to conduct tests on-site against a calibrated standard. Using the MASStrol as an example the K-factors would be programmed as follows. 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. Electrical pulse signals are induced at both ends of the coil. 2) Viscosity is an issue as thicker or thinner fluids can change the rotor speed and affect the meter's calibration.

Wittenberg is a nationally ranked liberal arts institution with a particular strength in the sciences. The k-factor values for Linear Advance 1.5 are vastly different from Linear Advance 1.0, and those k-factor values should fall somewhere between 0.0 and 2.0. The K-factor is the frequency divided by the flow rate => [1/s] / [g/s] = 1/g. This is because the characteristics of your electrode will change over time and this needs to be compensated for. It represents how many frequency signals per cube. Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with SunAgri and INRAE in Avignon between 2019 and 2022.
