Options are Calculated, Scaled AnInp2 or Digital Pulse.
• “Calculated” uses the ow rate setting “Pump Flow Rate” in the settings menus to calculate the current
Flow Rate.
• “Scaled AnInp2” uses an analogue sensor (ether current-loop or variable voltage ) to determine the
current Flow Rate.
• Digital Pulse uses a compatible digital output ow meter to determine the current Flow Rate.
