is needed for the pulse output. Use the second configuration if the voltage at
the flow meter power supply is an acceptable driver voltage for the load
connected. (Take into account that the current used by the pulse load comes
from the meter’s power supply). Use the third configuration if you have an
AC powered unit only. In any case, the voltage of the pulse output is the
same as the voltage supplied to the circuit.
