The current pulse repetition frequency is calculated from the current flow and the
configured pulse value:
Pulse repetition frequency = flow/pulse value
Example
• Flow: 24 l/min
• Pulse value: 0.001 l
• Pulse repetition frequency = 400 Pulse/s
The pulse output only outputs positive flow components in the set installation direction.
Negative flow components are ignored and not balanced.
Low flow cut off →  23 resets the pulse output.
Configuring the switch output
The Switch output submenu contains all the parameters that must be configured for the
configuration of the switch output.

Switch output
function • Off
The switch output is permanently switched off (open, non-conductive).
• On
The switch output is permanently switched on (closed, conductive).
• Diagnostic behavior
The output switches off when an event with the status signal F occurs
