1. Safety instructions
1. Please read through this Operating Manual very carefully before putting the
device into service. Carry out all steps strictly according to the instructions.
2. Take note of all instructions and illustrations.
3. Make sure the housing is fitted correctly again after opening. Otherwise foreign
bodies and moisture could penetrate the device.
4. In the following cases, the 230 V power supply must be disconnected immediately
and a technician called in:
• Water or other liquids have penetrated the device
• In spite of having carefully followed all of the instructions given in this
Operating Manual, the unit is not operating correctly
• If the unit is dropped and the housing damaged
• If the display on the unit is not working
• If one of the three buttons does not work
Under no circumstances must you attempt to repair anything yourself or try to
get things working by randomly pressing the buttons.
1.1 Installation
The device may only be installed by qualified specialist personnel while observing
customary local safety regulations.
During installation, make sure of the following:
• The direction of flow corresponds to the label on the unit
• The measuring device must be fitted in a horizontal position
• The unit must not be subjected to any mechanical stresses
• Only seals and connectors suitable for the planned operating conditions
must be used
• The pipework upstream and downstream of the device must be
appropriately supported
• The system must be vented before it is put into operation
The device and the flow sensor are not protected against overvoltage and polarity
reversal.
The integrated electronic system will not work without a power supply. If the
device is operated without a power supply, measurement is impossible.

FC PRO ENG Page 4
The FC PRO is an all-purpose electronic display and evaluation unit for operation
with approved DIGMESA AG flow sensors.
The FC PRO is used as an external display unit and is connected to the flow
sensor by means of a cable.
The FC PRO has been developed to measure and control the consumption of
liquids. The built-in LCD display informs the user of the volume that has flowed
through and the current flow rate. The alarm function is used to indicate when
a defined volume has been reached. A protective code prevents manipulation
by non-authorised persons.
Application examples:
• Monitoring filter cartridges
• Monitoring ion exchangers
• Checking drinks servings
• Monitoring cooling circuits
• etc...

6. Display
The Day counter can display up to 999‘999 litres. De-
pending on the pul/l value, up to 3 decimal places are
displayed.
The Current value indicates the current flow rate in litres
per minute (l/min).
The Total counter is a second counter for a max. of
99‘999 litres. It can be protected against (inadvertent/
unauthorised) resetting by a code. If the Mode button is
pressed once again, the display switches back to Day
counter.
If the Mode button is pressed once, the display switches
to the Current value.
If the Mode button is pressed once, the display switches
to the Total counter.
OK LED is illuminated.

RESET DAY COUNTER
Select the Day counter on the display and hold down
the Down and Up buttons simultaneously until RESET
appears briefly on the display and then the Day counter
reset to zero.
RESET TOTAL COUNTER
Select the Total counter on the display and hold down
the Down and Up buttons simultaneously until RESET
appears briefly on the display and then the Total counter
reset to zero.
OK LED is illuminated.
The last 5 resets are saved, with PoS 1 always being the

To query PoS 3, press the Up button briefly, then PoS 3
will be shown on the display alternatively with the saved
value. If the Up button is pressed again, PoS 4 is displa-
yed, and then if the Up button is pressed again, PoS 5
is displayed.
If no value is saved in one of the PoS 1 to 5, then „No
dATA“ appears and the display goes back to the last PoS
that has saved a value.
