2.3. OPERATOR INFORMATION AND FUNCTIONS
In general, the F113-A-OS will always function at Operator level. The information displayed is
dependant upon the SETUP-settings. The signal generated by the connected flowmeter is measured
by the F113-A-OS 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 F113-A-OS. 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.

Programming the flowrate alarm values
Note: This function might not be immediately accessible due to a configuration setting.
When the SELECT-key is pressed a few times, following flowrate alarm values are displayed:
low-low flowrate alarm (LL): enter here 20 L/min for example,
low flowrate alarm: enter here 40 L/min for example,
high flowrate alarm: enter here 200 L/min for example,
high-high flowrate alarm (HH): enter here 250 L/min for example.
To change the alarm value, the following procedure must be executed:
1) press PROG: the word "PROGRAM" will flash or a pass code will be requested,
2) use to select the digits and to increase that value,
3) confirm the new alarm value by pressing ENTER.
Fig. 4: Example of display information during programming minimum flowrate.
When data is altered but ENTER has not been pressed yet, then the alteration can still be
cancelled by waiting for 20 seconds or by pressing ENTER during three seconds: the former
value will be reinstated.
Flowrate alarm
When the actual flowrate is outside the allowed range, an alarm message will be displayed
indicating the type of alarm: "LO RATE", "HI RATE", "LO-LO RATE" or "HI-HI RATE".
The alarm is terminated automatically as soon as the flowrate is within its range again.
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.

3.2.3. EXPLANATION OF SETUP-FUNCTIONS
1 - TOTAL
MEASUREMENT UNIT
11
SETUP - 11 determines the measurement unit for total, accumulated total
and pulse output. 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, accumulated total and pulse output
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 20mA (or max signal).
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 20mA 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 20mA 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)!

HF113AEN_OS_v0501_05
Page 15
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.
Note: these settings also influence the analog output.
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 20mA (or maximum signal).
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 20mA at 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 20mA 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)!

HF113AEN_OS_v0501_05
Page 16
3 - ALARM
With these settings, it is determined how the flowrate will be monitored and the functionality of the
relay outputs (terminals 10-17) be determined.
Note: for relay output functions: read also SETUP 8 “relays”.
FLOW ZERO
31
When the flowrate is zero, then it is possible to ignore or disable the
flowrate monitoring. The following settings can be selected:
DEFAULT: in case of a low-flowrate alarm and zero flow, it will switch
the alarm output and indicate the alarm on the display.
NO RELAY: in case of a low-flowrate alarm and zero flow, it won't
switch the alarm output but will indicate the alarm on the
display only.
IGNORE: in case of a low-flowrate alarm and zero flow, it won't
switch the alarm output and nothing will be indicated on
the display.
ALARM VALUE

4 - DISPLAY
SET ALARM
41
This function determines if the flowrate alarm values can be set at both
Operator level and SETUP-level or SETUP-level only.
If SETUP has been selected, the alarm values are still visible for the
Operator but can not be changed.
FUNCTION
42
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.
5 - POWER MANAGEMENT
When used with the internal battery option (no option for the F113-A-OS), the user can expect
reliable measurement over a long period of time. The F113-A-OS 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 signal will be
processed and the output signals will be generated in the normal way.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
Example 3: Battery life-time
battery life-time with a FAST update: about 3 years.
battery life-time with a 1 sec update: about 7 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
52
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 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 F113-A can process the 4-20mA 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 20mA. 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 (0)4mA and value 1 (one) for 20mA.
FILTER
52
The analog output signal of a flowmeter does mirror the actual flow. This
signal is measured several times a second by the F113-A. The value
measured is a "snap-shot" of the real flow. With the help of this digital
filter a more 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:

6 - FLOWMETER (CONTINUED)
CUT-OFF
63
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 16mA (or 20mA / 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 61) SPAN (setup
13/24)
REQUIRED
CUT-OFF CUT-OFF (setup 63) REQUIRED OUTPUT
interpolation 450 L/min 25 L/min 25/450 x 100%=5.5% 16mA x 5.5% + 4mA = 4.88mA
square root 450 L/min 25 L/min (25/450)2 x 100%=0.3% 16mA x 0.3% + 4mA = 4.05mA
TUNE MIN / 4MA
64
With this setting it is possible to calibrate the input value for (0)4mA as the
signal from the flowmeter might not be exact 4.0 mA (or 0.0 mA) 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 "(0)4mA" 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.
TUNE MAX / 20MA
65
With this setting it is possible to calibrate the input value for 20mA as the
signal from the flowmeter might not be exact 20.0 mA 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 "20mA" 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.

7 - ANALOG OUTPUT
A linear analog (0)4-20mA or 0-10V signal is generated according to the flowrate with a 10 bits
resolution. The settings for flowrate (SETUP - 2) influence the analog output directly.
The relationship between rate and analog output is set with the following functions:
DISABLE / ENABLE
71
The analog output can be disabled.
3.5mA will be generated if a power supply is available but the output is
disabled (this is not valid in case type AB or AU has been supplied).
MINIMUM FLOWRATE
72
Enter here the flowrate at which the output should generate the minimum
signal (0/4mA or 0V) - in most applications at flowrate "zero".
The number of decimals displayed depend upon SETUP 23.
The time and measuring units (L/min for example) are dependant upon
SETUP 21 and 22 but are not displayed.
MAXIMUM FLOWRATE
73
Enter here the flowrate at which the output should generate the maximum
signal (20mA or 10V) - in most applications at maximum flow.
The number of decimals displayed depend upon SETUP 23.
The time and measuring units (L/min for example) are dependant upon
SETUP 21 and 22 but can not be displayed.
CUT-OFF
74
To ignore leakage of the flow for example, a low flow cut-off can be set as
a percentage of the full range of 16mA, (or 20mA or 10V).
When the flow is less than the required rate, the current will be the
minimum signal (0/4mA or 10V).
Examples:
4MA
(SETUP 72) 20MA (SETUP 73) CUT-OFF (SETUP 74) REQUIRED RATE OUTPUT
0 L/min 100 L/min 2% (100-0)*2% = 2.0 L/min 4+(16*2%) = 4.32mA
20 L/min 800 L/min 3.5% (800-20)*3.5%= 27.3 L/min 4+(16*3.5%)=4.56mA
TUNE MIN / 4MA
75
The initial minimum analog output value is 0/4mA or 0V. However, this
value might differ slightly due to external influences such as temperature
for example. The 0/4mA or 0V value can be tuned precisely with this
setting.
Before tuning the signal, be sure that the analog signal is not being
used for any application!
After pressing PROG, the current will be about 4mA (or 0mA / 0V). The
current can be increased / decreased with the arrow-keys and is directly
active. Press ENTER to store the new value.
Remark: the analog output value can be programmed “up-side-down” if
desired, so 20mA at minimum flowrate for example!
TUNE MAX / 20MA
76
The initial maximum analog output value is 20mA (or 10V). However, this
value might differ slightly due to external influences such as temperature
for example. The 20mA value (or 10V) can be tuned precisely with this
setting.
Before tuning the signal, be sure that the analog signal is not being
used for any application!
After pressing PROG, the current will be about 20mA. The current can be
increased / decreased with the arrow-keys and is directly active. Press
ENTER to store the new value.
Remark: the analog output value can be programmed “up-side-down” if
desired, so 4mA at maximum flowrate for example!
