You can connect an external pulse flowmeter to one
of the digital inputs in order to register the actual and
accumulated flows. Based on this, you can also
calculate the specific energy.
To enable a pulse flowmeter, set one of the digital
inputs to Accumulated flow and set the pumped
volume per pulse. See section Digital inputs.
