F6.61 K-FACTOR TABLE (ONLY FOR FREQUENCY
OUTPUT)
K-Factor is the number of pulses which a sensor produces for one liter of
measured fluid. Here below all K-Factors for water at room temperature are
listed.
K-Factor values can depend on the installation conditions. K-Factor has to
divide the frequency generated by F6.61 in order to achieve the flow rate (l/s).
Please contact your dealer for K-Factor values not included in the table.
