WebDec 26, 2024 · This K factor will be given in terms of the number of pulses produced by the meter for a given volume flow. (Example) 200 pulses per US gallon, 150 pulses per liter, etc. The K-Factor is a value that is entered into a batch table or an indicator/totalizer to express the reading in engineering units. WebIn the following discussion, the parameter K c,s represents the loss factor based on the combined flow, stream flow area, and velocity for the side branch. Similarly, K c,st is for the straight-through pipe (the run). Figure 1 depicts the nomenclature. K-factor subscripts refer to base area reference and location in the Tee.
