2.3. OPERATOR INFORMATION AND FUNCTIONS
In general, the F012-U will always act at Operator level. The information displayed is dependant
upon the SETUP-settings. The signal generated by the connected flowmeter is measured by the
F012-U in the background, whichever screen refresh rate setting is chosen. After pressing a key, the
display will be updated very 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 flowrate / total or flowrate
This is the main display information of the F012-U. 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.
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 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.
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 original batteries supplied by the manufacturer may be used, else the guarantee and
liability will be terminated. The remaining lifetime after the first moment of indication is
generally several days up to some weeks.

MEASUREMENT UNIT
11
SETUP - 11 determines the measurement unit for total and accumulated
total. The following units can be selected:
L - m3 - kg - lb. - GAL - USGAL - bbl - _ (no unit).
Alteration of the measurement unit will have consequences for operator
and SETUP-level values.
Please note that the Span has to be adapted as well; the calculation is not
done automatically.
DECIMALS
12
The decimal point determines for total and accumulated total the number
of digits following the decimal point.
The following can be selected:
0000000 - 111111.1 - 22222.22 - 3333.333
SPAN
13
With the span, the flowmeter signal is converted to a quantity.
The span for Total is determined on the basis of the measurement unit
(setting 11) and the flowrate per second at 10V.
Enter the span in whole numbers (decimals are set with SETUP 14).
The more accurate the span, the more accurate the functioning of the
system will be:
Example 1 Calculating the Span.
Let us assume that the flowmeter generates 10V at a rate of
652.31 USGAL per hour, the selected unit is barrels.
There are 42 gallons in one barrel; so the rate is 652.31/42 is
15.53119 barrels/hour.
This is 0.0043142 barrels/second, which is the span.
Enter for SETUP - 13: "004314" and for SETUP - 14 "6".
Example 2 Calculating the Span.
Let us assume that the flowmeter generates 10V at a
flowrate of 2,481.3 Liters/minute and the selected unit is "cubic
meters / m3".
The rate per second is 2,481.3÷60 is 41.355 L/sec.
This is 0.041355 m3/sec., which is the span.
Enter for SETUP - 13: "041355" and for SETUP - 14 - decimals
span "6".
DECIMALS SPAN
14
This setting determines the number of decimals for the Span
(SETUP 13). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this function influences the accuracy of the Span
indirectly.
This setting has NO influence on the displayed number of digits for total
(SETUP 12)!

HF012UEN_v0402_03 Atex_IECEx_CSA_FM
Page 14
2 - FLOWRATE
The settings for total and flowrate are entirely separate. In this way, different units of measurement
can be used for each e.g. cubic meters for total and liters for flowrate.
The display update time for flowrate is one second or more.
MEASUREMENT UNIT
21
SETUP - 21 determines the measurement unit for flowrate.
The following units can be selected:
mL - L - m3 - mg - g - kg - ton - GAL - bbl - lb - cf - REV - no unit -
scf - Nm3 - NL - P.
Alteration of the measurement unit will have consequences for operator
and SETUP-level values.
Please note that the Span has to be adapted as well; the calculation is not
done automatically.
TIME UNIT
22
The flowrate can be calculated per second (SEC), minute (MIN), hour
(HR) or day (DAY).
DECIMALS
23
This setting determines for flowrate the number of digits following the
decimal point. The following can be selected:
00000 - 1111.1 - 2222.22 - 3333.333
SPAN
24
With the span, the flowmeter signal is converted to a quantity.
The span for flowrate is determined on the basis of the selected
measurement unit and time unit at 10V.
Enter the span in whole numbers (decimals are set with SETUP 25).
The more accurate the span, the more accurate the functioning of the
system will be:
Example 1 Calculating the span for flowrate
Let us assume that the flowmeter generates 10Vat a
flowrate of 2,481.3 Liters/minute, the selected unit is
"Liters" and time unit "minute".
The span is 2481.3
Enter for SETUP - 24: "248130" and for SETUP - 25 -
decimals span "2".
Example 2 Calculating the span for flowrate
Let us assume that the flowmeter generates 10V at a rate
of 652.31 USGAL per hour, the selected unit is USG and
the time unit is minute.
The span is 652.31 / 60 minutes is 10.87183 (GPM).
Enter for SETUP - 24: "108718" and for SETUP - 25 "4".
DECIMALS SPAN
25
This setting determines the number of decimals for the Span
(SETUP 24). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this SETUP - influences the accuracy of the Span
indirectly.
This setting has NO influence on the displayed number of digits for
"flowrate" (SETUP 23)!

HF012UEN_v0402_03 Atex_IECEx_CSA_FM
Page 15
3 - DISPLAY
FUNCTION
31
The large 17mm digits can be set to display total or flowrate.
When "total" is selected, both total and flowrate are displayed
simultaneously.
When "flowrate" is selected, only flowrate will be displayed with it’s
measuring unit while total will be displayed after pressing SELECT.
The functions below will only effect the optional LED-backlight.
BACKLIGHT
(OPTION)
32
If a LED backlight has been supplied, the color can be selected.
Following selections are available:
OFF - GREEN - AMBER
BRIGHTNESS
(OPTION)
33
The density of the backlight can be set in following range:
1-5
One is minimum and five is maximum brightness.
4 - POWER MANAGEMENT
When used with the internal battery option, the user can expect reliable measurement over a long
period of time. The F012-U has several smart power management functions to extend the battery life
time significantly. Two of these functions can be set:
LCD NEW
41
The calculation of the display-information influences the power
consumption significantly. When the application does not require a fast
display update, it is strongly advised to select a slow refresh rate.
Please understand that NO information will be lost; the input signal will be
processed and the output signal will be generated in the normal way.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
Example battery life-time:
battery life-time with a FAST update: about 3 years.
battery life-time with a 1 sec update: about 5 years.
Note: after a button has been pressed by the operator - the display
refresh rate will always switch to FAST for 30 seconds. When "OFF" is
selected, the display will be switched off after 30 seconds and will be
switched on as soon as a button has been pressed.
BATTERY-MODE
42
The unit has two modes: operational or shelf.
After "shelf" has been selected, the unit can be stored for several years; it
will not process the sensor signal; the display is switched off but all
settings and totals are stored. In this mode, power consumption is
extremely low.
To wake up the unit again, press the SELECT-key twice.
5 - FLOWMETER
SIGNAL
51
The F012-U can process the 0-10V signal in two ways:
Interpolation: the signal is processed linear
R = S x I
Square root: for differential pressure
R = S √I
where:
R = Rate: the calculated flowrate
S = Span: the maximum flowrate at 10V. The span is programmed
with setting 24 for flowrate and with setting 13 for total.
I = Input: the scaled analog value; in these formulas value 0 (zero)
for 0V and value 1 (one) for 10V.

HF012UEN_v0402_03 Atex_IECEx_CSA_FM
Page 16
5 - FLOWMETER (CONTINUED)
FILTER
52
The analog output signal of a flowmeter does mirror the actual flow. This
signal is measured several times a second by the F012-U. The value
measured is a "snap-shot" of the real flow as it will be fluctuating. With the
help of this digital filter a stable and accurate reading can be obtained
while the filter level can be set to a desired value.
The filter principal is based on three input values: the filter level (01-99),
the last measured analog value and the last average value. The higher
the filter level, the longer the response time on a value change will be.
Below, several filter levels with there response times are indicated:
FILTER VALUE RESPONSE TIME ON STEP CHANGE OF ANALOG VALUE.

75 13 seconds 26 seconds 43 seconds 86 seconds
99 17 seconds 34 seconds 57 seconds 114 seconds
CUT-OFF
53
To ignore e.g. leakage of the flow or vibration, a low-flow cut-off can be
set as percentage over the full range of 10V. When the analog value is
less then required with this setting, the signal will be ignored.
The cut-off value can be programmed is the range 0.0 - 99.9%.
Examples:
FUNCTION
(setup 51) SPAN (setup
13/24)
REQUIRED
CUT-OFF CUT-OFF (setup 53) REQUIRED OUTPUT
interpolation 450 L/min 25 L/min 25/450 x 100%=5.5% 10V x 5.5% = 0.55V
square root 450 L/min 25 L/min (25/450)2 x 100%=0.3% 10V x 0.3% = 0.3V
TUNE MIN / 0V
54
With this setting it is possible to calibrate the input value for 0V as the
signal from the flowmeter might not be exact 0.0V at flowrate zero.
This function will measure the real output value at flow zero.
Warning: be very sure that the offered signal is correct
before the calibration is executed as this function has major
influences on the accuracy of the system!
After pressing PROG, three settings can be selected:
CALIBRATE: with this setting, the input will be calibrated with the
actual "0V" value. After pressing enter, CAL SET will be displayed as
soon as the calibration is completed. From that moment, the analog
value must be more than the calibrated value before the signal will be
processed.
DEFAULT: with this setting, the manufactures value is re-installed.
CAL SET: to select the last calibrated value.

With this setting it is possible to calibrate the input value for 10V as the
signal from the flowmeter might not be exact 10.0V at maximum flowrate.
This function will measure the real output value at maximum flowrate.
Warning: be very sure that the offered signal is correct
before the calibration is executed as this function has major
influences on the accuracy of the system!
After pressing PROG, three settings can be selected:
CALIBRATE: with this setting, the input will be calibrated with the
actual "10V" value. After pressing enter, CAL SET will be displayed as
soon as the calibration is completed. From that moment, the analog
value must be less than the calibrated value for a reliable
measurement.
DEFAULT: with this setting, the manufactures value is re-installed.
CAL SET: to select the last calibrated value.
