  • Page 40: K-Factors Explained

    K-Factors Explained K-FACTORS EXPLAINED The K-factor (with regard to flow) is the number of pulses that must be accumulated to equal a particular volume of fluid You can think of each pulse as representing a small fraction of the totalizing unit An example is a K-factor of 1000 (pulses per gallon) This means that if you were counting pulses, when the count total reached 1000, you would have accumulated one gallon of liquid Using the same reasoning, each individual pulse represents an accumulation of...
  • Page 41 K-Factors Explained Example 2 Known values are: Full Scale Flow Rate 85 gpm Full Scale Output Frequency = 650 Hz 650 Hz × 60 sec = 39,000 pulses per min 39,000 pulses per min K-factor 458.82 pulses per gallon 85 gpm The calculation is a little more complex if the velocity is used because you first must convert the velocity into a volumetric flow rate to be able to compute a K-factor To convert a velocity into a volumetric flow, the velocity measurement and an accurate...
