13.1 Connection Pulse Interface
The pulse interface has two outputs – Volume and Energy. flowIQ® 3100 only uses the volume output.
Each pulse output consists of 3 terminals: GND, Volume Pulse and Pull-up Volume. When the pulse output
is atie, Pulse is da to GND, i.e. the output is atie lo. A kΩ resistance is placed from Pull-Up to
Pulse.
The supply for terminals 1 and 2 and the supply connected to the Pull-Up do not need to be the same or at
the same level. The connection of the 8-pole plug J1 is indicated in figures below/next page.
