4. INTRODUCTION
4.1 System description of the F110
The display / totalizer F110 is a battery-powered device driven by microprocessors for displaying of the flow rate, total and
accumulated total. For that purpose, one flow meter can be connected to the F110. Two outputs are standardly available:
• Pulse output (open collector): A scaled pulse mirroring the count on the display is generated for use by external
instruments like counters for example.
• The passive analogue output with 10 bits’ resolution has programmable set points according to the flow rate for both
4mA and 20mA.
Furthermore, options are available for full communication RS232/485 (also battery powered) and intrinsically safe.
The F110 is designed to be implemented in many types of applications. For that reason, a SETUP level is available to configure
your display/totalizer best according to your requirements. SETUP includes several important features as K-factors,
measurement units, signal selection, etc. To extend the battery life time, please make use of the power management
functions as described in chapter 6.4.4.
