What does the binary number 0111 represent? 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. The procedure for analog inputs is essentially the same as for pulse inputs. This calculation has built-in error factors based on a relatively imprecise primary input coupled with conversions from analog frequency and sometimes back to analog for transmission purposes. A view of the correction factor in an experimental result allows the evaluators of the result to analyze it, keeping in mind the impact of uncertainty factors on the results. The axial design of Turbine Flow Meter is inherently linear within a known turndown range, typically 15:1, based on velocity of the measured fluid. Calibration is a comparison between a known measurement (the standard) and the measurement using your instrument.
