OPERATOR INFORMATION AND FUNCTIONS
In general, the F127-P-EL will always function at Operator level. The information displayed depends
upon the SETUP-settings. All pulses generated by the connected flowmeter are measured by the
F127-P-EL in the background, whichever screen refresh rate setting is chosen. After pressing a key,
the display will be updated quickly during a 30 second period, after which it will slow down again.
Fig. 3: Example of display information during process.
For the Operator, the following functions are available:
Display calculated differential flowrate and calculated differential total
This is the main display information of the F127-P-EL. After selecting any other information, it
will always return to this main display automatically.
Total is displayed on the upper-line of the display and flowrate on the bottom line.
It is possible to display flowrate only with the large 17mm digits; in this instance press the
SELECT-key to read the total. When "-------" is shown, then the flowrate value is too high to be
displayed. The arrows
indicate the increase/decrease of the flowrate trend.
If the consumption is very low, it might be that a stable low flowrate is displayed and and a
stable totalisation; this is due to the settings of the unit.
Clear total
The value for total can be re-initialized. To do so, press CLEAR twice. After pressing CLEAR
once, the flashing text "PUSH CLEAR" is displayed. To avoid re-initialization at this stage,
press another key than CLEAR or wait for 20 seconds.
Re-initialization of total DOES NOT influence the accumulated total.
Display calculated differential accumulated total
When the SELECT-key is pressed, total and accumulated total are displayed. The
accumulated total cannot be re-initialized. The value will count up to 99,999,999,999. The unit
and number of decimals are displayed according to the configuration settings for total.
Display line temperature and calculated flowrate INLET / OUTLET
After pressing SELECT, the actual INLET / OUTLET temperature is displayed at the top line
of the display. At the bottom line, the calculated INLET / OUTLET flowrate is displayed
together with the measuring units for flowrate and temperature.
Low-battery alarm
When the battery voltage drops, it must be replaced. At first "low-battery" will flash, but as
soon as it is displayed continuously, the battery MUST be replaced shortly after!
Only official batteries may be used, or else the guarantee will be terminated. The remaining
lifetime after the first moment of indication is generally several days up to some weeks.

Alarm 01-03
When "alarm" is displayed, please consult Appendix B: problem solving.
