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. Your Bowden should be higher, but the value might be . Some of common factors that would normally have an effect on the accuracy of a pressure calibrator measurement are: hysteresis, repeatability, linearity, temperature, and gravity. Each pulse generated represents a discrete amount of volumetric throughput. It represents how many frequency signals per cube. The first cycle is a relatively rapid cycle from 0 to 100 percent of the calibration. M900 K0.18. This is similar to uncertainty for the prediction of a new measurement. Only after the K-factor is known can the frequency counter indicate the flow rate and the total flow, and only then is the system accurate and according to specifications. This article is dedicated to helping you understand the meaning of k=2 and how it affects the validity of a calibration. Multiply this value by 100% to obtain the percent error. Calculations Using K-Factors 1. K-values for Linear Advance 1.0 and 1.5 are not compatible. The K-factor is a constant, referring to the number of measurable pulses required for a given volume of fuel to pass through the point where flow is being measured. When a trigonal column vortex generator is set in the fluid, regular vortices are generated alternately on both sides of the vortex generator, which is called Carmen vortex. Home Flow Measurement Solutions What is Flow Meter K-factor? huahengxa@gmail.com 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. Verify it using a host software like. Therefore, this frequency of the pulse output is proportional to the rate of the flow. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. The calibration range is the interval comprising the measurement values possible when registered with a measuring device and typical for the respective measurement process. Note that because the K-factor for the last two points are the same, any frequency higher than 43.67 Hz will be modified by a K-factor of 52.4 The set up is now complete.
