Vicenza is the Italian and indeed world Read more, What fish can live with Tropheus? A wide variety of flow meters options are available to you, such as free samples, paid samples. Calibration standards are devices that are compared against less accurate devices to verify the performance of the less accurate devices. The Y-factor looks at a similar value, but it takes the stresses inherent in the material into consideration, making it more accurate than the K-factor. 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? From the above calibration sheet data we can relate the incoming frequency to the K-factor as follows. signal. 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.
