2.3. OPERATOR INFORMATION AND FUNCTIONS
In general, the F112-P will always act at Operator level. The information displayed is dependant
upon the SETUP-settings. All pulses generated by the connected flowmeter are measured by the
F112-P 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.
All information displayed is corrected by using the linearization table as stored in the F112-P.
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 F112-P. 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.

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 K-factor 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
K-FACTOR
13 With the K-factor, the flowmeter pulse signals are converted to a quantity.
The K-factor is based on the number of pulses generated by the
flowmeter per selected measurement unit (SETUP 11), for example per
cubic meter. The more accurate the K-factor, the more accurate the
functioning of the system will be.
Example 1: Calculating the K-factor.
Let us assume that the flowmeter generates 2.4813 pulses per
liter and the selected unit is "cubic meters / m3". A cubic meter
consists of 1000 parts of one liter which implies 2,481.3 pulses
per m3. So, the K-factor is 2,481.3. Enter for SETUP - 13:
"2481300" and for SETUP - 14 - decimals K-factor "3".
Example 2: Calculating the K-factor.
Let us assume that the flowmeter generates 6.5231 pulses per
gallon and the selected measurement unit is gallons. So, the K-
Factor is 6.5231. Enter for SETUP - 13: "6523100" and for
SETUP - 14 decimals K-factor "6".
DECIMALS K-FACTOR
14 This setting determines the number of decimals for the K-factor entered.
(SETUP 13). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this setting influences the accuracy of the K-factor
indirectly. (i.e. the position of the decimal point and thus the value given)
This setting has NO influence on the displayed number of digits for total
(SETUP 12)!

HF112PEN_v0501_04
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.
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 K-factor 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
K-FACTOR
24 With the K-factor, the flowmeter pulse signals are converted to a flowrate.
The K-factor is based on the number of pulses generated by the
flowmeter per selected measurement unit (SETUP 21), for example per
liter. The more accurate the K-factor, the more accurate the functioning of
the system will be. For examples read SETUP 13.
DECIMALS K-FACTOR
25 This setting determines the number of decimals for the K-factor
(SETUP 24). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this SETUP - influences the accuracy of the K-factor
indirectly.
This setting has NO influence on the displayed number of digits for
"flowrate" (SETUP 23)!
CALCULATION
26 The flowrate is calculated by measuring the time between a number of
pulses, for example 10 pulses. The more pulses the more accurate the
flowrate will be. The maximum value is 255 pulses.
Note: this setting does influence the update time for the analog output
directly (maximum update 10 times a second). If the output response is
too slow, decrease the number of pulses.
Note: the lower the number of pulses, the higher the power consumption
of the unit will be (important for battery powered applications).
Note: for low frequency applications (below 10Hz): do not program more
than 10 pulses else the update time will be very slow.
Note: for high frequency application (above 1kHz) do program a value of
50 or more pulses.
CUT-OFF TIME
27 With this setting, you determine a minimum flow requirement thresh-hold,
if during this time less than XXX-pulses (SETUP 26) are generated, the
flowrate will be displayed as zero.
The cut-off time has to be entered in seconds - maximum time is 999
seconds (about 15 minutes).

HF112PEN_v0501_04
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.
4 - POWER MANAGEMENT
When used with the internal battery option, the user can expect reliable measurement over a long
period of time. The F112-P has several smart power management functions to extend the (optional)
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; every pulse will be
counted 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 coil pick-up, 1KHz. pulses and FAST
update: about 2 years.
battery life-time with a coil pick-up, 1KHz. pulses and 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 count pulses, 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.

6 - LINEARISATION
The linearization function is available to approach the real flow curve better as with the general
K-factor (KF0) entered with setup 14 and 24. This to obtain a more accurate flowrate, total and
accumulated total as well as the analog and pulse output at any flowmeter frequency.
A maximum of 15 linearization-positions can be entered while the interpolation will calculate any
other position in-between.
For each linearization position, the frequency and a Meter Factor (MF) must be entered.
The Meter Factor for each frequency is calculated with following formula:
Meter-Factor = K-Factor at flowrate X
KF0
The lowest frequency and MF you enter will be valid from 0Hz. The highest frequency and MF will
be valid till 10KHz. It is advised to enter the frequencies in increasing order, however it is not
necessary. Please have a look at following example to understand the method of linearization:
FREQUENCY /
M-FACTOR
61 TO 6F
The frequency is displayed at the bottom line of the display.
The maximum frequency is 9,999.9 Hz. With value 0.0Hz, the M-Factor is
disabled. (Please read Setup function 6H - decimals frequency)
The M-Factor is displayed at the top-line of the display. The minimum
value to be entered is 0.000001 and the maximum value is 9.999999.
Please note that this value has always six decimals while the "dot" is not
displayed.
Most M-factors will be around 1.000000 like 0.945354 or 1.132573.

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.
In case of a passive analog output type AP, 3.5mA will be generated if a
power supply is available but the output is disabled.
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) depend 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) depend upon SETUP
21 and 22 but cannot 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

7 - ANALOG OUTPUT (CONTINUED)
FILTER
77 This function is used to stabilize the analog output signal.
The output value is updated every 0.1 second. With the help of this digital
filter a more stable but less precise reading can be obtained.
The filter principal is based on three input values: the filter level (01-99),
the last analog output 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 their response times are indicated:
FILTER VALUE RESPONSE TIME ON STEP CHANGE OF ANALOG VALUE.

8 - RELAY OUTPUT
One transistor or mechanic relay output is available as scaled pulse output according to the
accumulated total.
PERIOD TIME
PULSE OUTPUT
81
The period time determines the time that the transistor or relay will be
switched; in other words the pulse length. The minimum time between the
pulses is as long as the selected period time.
One period is approx. 7.8 msec. If the value selected is “zero”, the pulse
output is disabled. The maximum value is 255 periods.
Note: If the frequency should go out of range - when the flowrate
increases for example - an internal buffer will be used to "store the missed
pulses": As soon as the flowrate reduces again, the buffer will be
"emptied".
It might be that pulses will be missed due to a buffer-overflow, so it is
advised to program this setting within it's range.
If a mechanic relay is used for the pulse output, it is recommended to
reduce the max. output frequency to 0.5Hz, else the life time will be
reduced significantly.

1 0,0078 seconds 64 Hz.
