1. INTRODUCTION
1.1. SYSTEM DESCRIPTION
Functions and features
The flow rate / totalizer model F115-P is a microprocessor driven instrument designed to show the
flow rate, the total and the accumulated total. This model is able to detect the flow direction and to
show a positive or negative flow rate, the totals for both directions and the cumulative totals.
This product has been designed with a focus on:
ultra-low power consumption to allow long-life battery powered applications (type PB/PC),
intrinsic safety for use in hazardous applications (type XI);
several mounting possibilities with aluminum or GRP enclosures for harsh industrial
surroundings;
ability to process all types of flowmeter signals;
transmitting possibilities with analog / pulse and communication outputs.
Flowmeter input
This manual describes the unit with a pulse input from the flowmeter. Other versions are available to
process (0)4-20mA signals.
Two flowmeters with a passive or active pulse, Namur or sine wave (coil) signal output, with a phase
difference of 90 or 270 degrees, can be connected to the F115-P. To power the sensor, several
options are available.
Standard outputs
Pulse output to transmit a pulse that represents a totalized quantity as programmed.
Negative / positive pulse output indication.
Linear (0)4-20mA or 0-10V analog output to represent the actual flow rate as programmed. The
(0)4-20mA or 0-10V signal limits can be tuned.

Configuration of the unit
The F115-P is designed for use in many types of applications. For that reason, a setup menu is
available to program the F115-P according to your specific requirements.
The setup includes several important features, such as K-Factors, engineering units, signal
selection, power management (to extend battery life-time), etc. All settings are stored in a non-
volatile memory and therefore kept in the event of a power failure or an exhausted battery.
Display information
The unit has a LCD with (optional) backlight to show the process information, status and alarm messages.
The display refresh rate is programmed in the setup menu.
At a key press, the display refresh rate will switch to FAST for 30 seconds. When 'OFF' is selected,
the display goes off after 30 seconds after the last key press. The display temporarily comes on after
a key press.
A backup of the total and accumulated total in EEPROM memory is made every minute.
Options
The following options are available: isolated or active (0)4-20mA / 0-10V analog output, full Modbus
communication RS232/485/TTL (also battery powered), intrinsic safety, mechanical relay or active
output, power- and sensor-supply options, panel -mount, wall-mount and weather-proof enclosures,
flame proof enclosure and LED backlight.

2.3. OPERATOR INFORMATION AND FUNCTIONS
In general, the F115-P operates in the operator
mode. The shown information depends on the
settings which are made in the setup menu.
The signal from the connected sensor is processed
by the F115-P in the background, independent from
the selected display refresh rate.
Fig. 3: Process information (typical)
For the Operator, the following functions are available:
Display differential flow rate / total or flow rate
This is the main display information of the F115-P. After the selection of any other information, it
will always return to this main display automatically. Differential total is shown on the upper line
of the display and flow rate on the bottom line. When selected in the setup menu, the display
shows the flow rate only. When you press the select key, the total shows momentarily.
When "-------" is shown, the flow rate value is too high to be displayed. The arrows indicate
the increase/decrease of the flow rate trend. For the total, the differential total is shown.
Based on the configuration, the following information is shown in case of reverse-flow:
- flow rate will be negative and total will count down, or
- flow rate value will be zero and no totalization, or
- flow rate will be positive and total will count up.
Clear total
The value for total can be reset. To do so, press the CLEAR/key twice. When the key is
pressed once, the text "PUSH CLEAR" is shown. To avoid a reset at this stage, press another
key other than the CLEAR/key or wait for 20 seconds. A reset of the total does not influence
the accumulated total.
Display accumulated total
When the SELECT/key is pressed, total and accumulated total are shown. The accumulated
total cannot be reset. The value will count up to 99,999,999,999. The unit and number of
decimals are shown according to the settings for the total.
Low-battery alarm
Only use original batteries. Original batteries can be ordered at the manufacturer.
The use of unapproved batteries will void the warranty.

At the end of the battery’s life-time, the
voltage starts to drop. When the voltage
becomes too low, the battery indicator comes
on. When the battery indicator is on, install a
new and fresh battery as soon as possible.

3.1.2 EXPLANATION OF SETUP-MENU 1 - TOTAL-A
UNIT
11
This setting is used to select the engineering unit for the indication of the
differential total, total (A and B), the accumulated total (A and B), and the pulse
output.
When you change the engineering unit, you must recalculate and
reprogram the K-factor for the (accumulated) total. When you
recalculate and reprogram the K-Factor, the history for
(accumulated) total is not correct anymore, because the
(accumulated) total is not recalculated. For future reference, best
practice is to make a note of the accumulated total before you
program the recalculated K-Factor.
DECIMALS
12
This setting is used to set the amount of digits behind the decimal point for the
(accumulated) total indication (A and B).
K-FACTOR
13
The K-Factor A determines the calculation factor for the forward total !
This setting is used to set the K-Factor for the total (A). 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 engineering unit, for
example per m3. A more accurate K-Factor (more decimals, as set in decimals
K-Factor) allows for a more accurate operation of the system.
Example 1: Calculating the K-Factor.
The flowmeter generates 2.4813 pulses per liter and the selected unit is m3. A
cubic meter consists of 1000 liter which gives 2.4813 pulses*1000 liter=2481.3
pulses per m3. So, the K-Factor is 2481.3. Enter for the Flowmeter K-Factor:
24813 and for the flowmeter K-Factor decimals: 1.
Example 2: Calculating the K-Factor.
The flowmeter generates 6.5231 pulses per gallon and the selected engineering
unit is gallons. So, the K-Factor is 6.5231. Enter for the Flowmeter K-Factor:
65231 and for the Flowmeter K-Factor decimals: 4.
When you recalculate and reprogram a new K-Factor, the history for
(accumulated) total is not correct anymore, because the
(accumulated) total is not recalculated. For future reference, best
practice is to make a note of the accumulated total before you
program the recalculated K-Factor.
DECIMALS K-FACTOR
14
This setting is used to set the amount of digits behind the decimal point for the
K-Factor (A).
3.1.3 EXPLANATION OF SETUP-MENU 2 - FLOW RATE-A
The settings for total and flow rate are entirely separate. In this way, different engineering units can
be used for each e.g. cubic meters for total and liters for flow rate.
UNIT
21
This setting is used to select the engineering unit for the indication of the flow rate
(A and B).
Alteration of the engineering unit will have consequences for
operator and setup values, they will not be automatically
recalculated to the value of the new selected unit. The K-Factor has
to be adapted as well; the calculation is not done automatically.
TIME
22
This setting is used to set the time unit for the flow rate calculation (A and B). Note
that the flow rate is given in engineering unit/time unit, e.g. liters/minute (l/min).
When you change this setting, also recalculate and change the settings
for the analog rate-min and analog rate-max.
DECIMALS
23
This setting is used to set the amount of digits behind the decimal point for the
flow rate indication (A and B).

FW_F115P_v1702_02_EN
Page 14
K-FACTOR
24
This setting is used to set the K-Factor for the flow rate (A). 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 engineering unit, for
example per m3. A more accurate K-Factor (more decimals, as set in decimals
K-Factor) allows for a more accurate operation of the system.
DECIMALS K-FACTOR
25
This setting is used to set the amount of digits behind the decimal point for the
K-Factor (A).
CALCULATION
26
The flow rate is calculated by measuring the time between a number of
pulses, for example 10 pulses. The more pulses the more accurate the
flow rate will be. The maximum value is 255 pulses.
This setting does influence the update interval for the flow rate and
thus, indirectly the update interval of the analog output.. (maximum
update 10 times a second). If the output response is too slow, decrease
the number of pulses. For low frequency applications (< 10Hz): do not
program more than 10 pulses, else the update time will be very slow.
For high frequency applications (> 1kHz): do program 50 or more pulses.
CUT-OFF
27
This setting is used to set the threshold for a minimum flow. If during this
time less than XXX-pulses are generated (refer to Calculation), the flow
rate will be shown as zero. The cut-off has to be entered in seconds.
3.1.4 EXPLANATION OF SETUP-MENU 3 - TOTAL-B
For Total, you can only set the K-Factor B when in the flowmeter menu the K-Factor is set to Dual.
Per default setting, the K-Factor is set to single (K-Factor A = K-Factor B). When Dual is selected,
the Total-B settings are not visible (editable). This is normal behavior.
K-FACTOR
31
K-Factor B determines the calculation factor for the reverse total !
This setting is used to set the K-Factor for the total (B). 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
engineering unit, for example per m3. A more accurate K-Factor (more
decimals, as set in decimals K-Factor) allows for a more accurate
operation of the system.
DECIMALS K-FACTOR
32
This setting is used to set the amount of digits behind the decimal point for the
(accumulated) total indication (B).
3.1.5 EXPLANATION OF SETUP-MENU 4 - FLOW RATE-B
For Flow rate, you can only set the K-Factor B when in the flowmeter menu the K-Factor is set to
Dual. Per default setting, the K-Factor is set to single (K-Factor B = K-Factor A). When Dual is
selected, the Total-B settings are not visible (editable). This is normal behavior.
K-FACTOR
41
K-Factor B determines the calculation factor for the reverse flow rate !
This setting is used to set the K-Factor for the flow rate (B). 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 engineering unit, for example per m3. A more accurate K-Factor
(more decimals, as set in decimals K-Factor) allows for a more accurate
operation of the system.
DECIMALS K-FACTOR
42
This setting is used to set the amount of digits behind the decimal point for the
K-Factor (B).
3.1.6 EXPLANATION OF SETUP-MENU 5 - DISPLAY
FUNCTION
51
This setting can be set to display differential total or rate.
When 'total' is selected, simultaneously, total is shown with the large digits and
flow rate with the smaller digits. When SELECT is pressed, the accumulated
total is shown temporarily.
When 'rate' is selected, only flow rate will be shown with the large digits
together with its engineering unit. When SELECT is pressed, the total and the
accumulated total are shown temporarily.
SHOW A-B
52
This setting determines the behavior of the operator menu. You can select
differential totals only (disable) or differential totals and accumulated totals
for flow A and flow B separately (enable).

LIGHT
53
The backlight brightness can be adjusted from 0% (off) to 100% (full brightness) in
steps of 20%.
When the F115-P is only loop powered, the backlight is disabled. An external
power supply is required to supply the backlight.
3.1.7 EXPLANATION OF SETUP-MENU 6 - POWER MANAGEMENT
When used with the internal battery option (type PB/PC), the user can expect reliable measurement over a long
period of time. The F115-P has several smart power management functions to extend the battery life time
significantly. Two of these functions can be set.
LCD NEW
61
The calculation of the display-information influences the power consumption
significantly. When the application does not require a fast display refresh rate, 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.
At a key press, the display refresh rate will switch to FAST for 30 seconds. When
'OFF' is selected, the display goes off after 30 seconds after the last key press.
The display temporarily comes on after a key press.
Example battery life-time with a coil pick-up:
1kHz pulse and FAST update: about 2 years;
1kHz pulse and 1 sec update: about 5 years.
BATTERY-MODE
62
The F115-P has two modes: operational or shelf.
After "shelf" has been selected, the F115-P 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 F115-P again, press the SELECT/key two times.
3.1.8 EXPLANATION OF SETUP-MENU 7 - FLOWMETER
The F115-P is able to handle several types of input signal. The pickup / signal is selected with:
SETUP 71 (Input A), Read also chapter 4
SETUP 72 (Input B), Read also chapter 4.
The selections "active pulse" offer a detection level of 50% of the supply voltage.

SIGNAL B
72
The secondary signal B is used to detect the direction of flow.
In most applications, the type of signal for input B will be the same type as
the main signal A (setting 71). For selection, read setting 71.
BI-DIRECTIoNAL
73
The secondary pulse input B of the F115 can be set to:
disable: input B will be ignored; the unit will act as a normal flow rate /
totalizer.
enable: the phase difference between flow A and flow B is used to
detect the flow-direction in the flowmeter.
PHASE
74
The phase difference between flow A and flow B can be set to 90 degrees or
270 degrees. In this way, you can easily swap the input signal to make it
count positive/negative.
COUNT NEGATIVE
75
This setting determines if a negative (reverse) flow should result in
processing the signal or if a reverse flow has to be ignored:
disable: a reverse flow will be ignored: flow rate will be zero and totals
will not count.
enable: a reverse flow will be processed: flow rate will be displayed and
total will be counted. Setup 76 determines how the signal will be
processed.
K-FACTOR
76
With this setting you can determine if the flow A and the Flow B use the
same K-Factor (as set for flow rate A) or different K-Factors for each flow.
When single is selected, the menus for total B and Flow rate B are empty.
CALCULATE
77
According to setting 76 - enable, select the way of calculation:
Add:
Forward flow rate will be calculated (signed) positive. Total, accumulated
Total and Total A will count up.
Reverse flow rate will be calculated (signed) positive. Total, accumulated
Total and Total B will count up.
Diff:
Forward flow rate will be calculated (signed) positive. Total, accumulated
Total and Total A will count up.
Reverse flow rate will be calculated (signed) negative. Total, accumulated
total and Total B will count down.
3.1.9 EXPLANATION OF SETUP-MENU 8 - ANALOG OUTPUT
A linear 4-20mA signal (option AB: 0-20mA or option AU: 0-10V) output signal is generated that
represents the flow rate. The settings for the flow rate influence the analog output directly. The
relationship between the flow rate and the analog output is set with the following settings.
OUTPUT
81
If the analog output is not used, select disable to minimize the power consumption
(e.g. save battery life-time).
Option AP: When a power supply is available but the output is disabled, a 3.5mA
signal will be generated.
RATE-MIN
82
Enter here the flow rate at which the output should generate the minimum signal
(0)4mA or 0V - in most applications at zero flow. The number of decimals shown
depend upon setup 23. The engineering units/time (e.g. L/min) are dependent upon
setup 21 and 22.
RATE-MAX
83
Enter here the flow rate at which the output should generate the maximum signal
(20mA or 10V) - in most applications at maximum flow. The number of decimals
shown depend upon setup 23. The engineering units/time (e.g. L/min) are dependent
upon setup 21 and 22.
RATE-NEG
84
In case a negative flow rate is displayed. it can be set to:
absolute: a negative flow rate will result in a normal positive analog
output signal as if it is a positive flow.
ignore: a negative flow rate results in a minimum output value (in most
cases 4mA or 0V).
CUT-OFF
85
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, 20mA or 10V.
When the flow is less than the required rate, the current will be the minimum signal
(0)4mA or 0V.
Example: Calculate the cut-off.
Rate-min: 0L/min [4mA], Rate-max: 100 L/min [16mA], Cut-off: 2%
Required rate [L/min]: (rate-max - rate-min)*cut-off: (100-0)*2%=2.0L/min
Output [mA]: rate-min + (rate-max*cut-off): 4+(16*2%)=4.32mA

FW_F115P_v1702_02_EN
Page 17
TUNE-MIN
86
The (0)4mA or 0V value can be tuned precisely with this setting. The initial minimum
analog output value is (0)4mA or 0V. However, this value might differ slightly due to
ambient influences such as temperature for example.
Before tuning the signal, make sure that the analog signal is idle (not used) for
any application!
After pressing PROG, the current will be about 4mA (0mA or 0V). The current can be
increased / decreased with the arrow keys and is directly active. Press ENTER to
store the new value.
If required, you can program the analog output 'up-side-down'. The (0)4mA or 0V
represents the maximum flow rate and the 20mA or 10V represents the minimum
flow rate.
TUNE-MAX
87
The 20mA or 10V value can be tuned precisely with this setting. The initial maximum
analog output value is 20mA or 10V However, this value might differ slightly due to
ambient influences such as temperature for example.
Before tuning the signal, make sure that the analog signal is idle (not used) for
any application!
After pressing PROG, the current will be about 20mA or 10V. The current can be
increased / decreased with the arrow keys and is directly active. Press ENTER to
store the new value.
If required, you can program the analog output 'up-side-down'. The (0)4mA or 0V
represents the maximum flow rate and the 20mA or 10V represents the minimum
flow rate.
FILTER
88
This setting is used to stabilize the output signal. With the help of this digital filter a
more stable but less actual representation of the flow rate can be obtained.
The filter principal is based on three input values: the filter level (01-99), the last
calculated flow rate and the last average value. The higher the filter level, the longer
the response time on a value change will be.

3.1.10 EXPLANATION OF SETUP-MENU 9 - PULSE
Two transistor or mechanic relay outputs are available as scaled pulse output according to the total.
MODE
91
The unit has three scaled pulse output modes. This functionality drives two pulse
outputs which, depending on the mode, can be used as follows:
not negative
On pulse output R1 a pulse will be sent when the total has increased with the set
quantity (SETUP 94). On pulse output R2 the sign of the flow rate will be send
(positive=0, negative=1).
separated
On pulse output R1 a pulse will be sent when the total has increased with the set
quantity (SETUP 94). On pulse output R2 a pulse will be sent when the total has
decreased with the set quantity (SETUP 94).
signed
On pulse output R1 a pulse will be send when the total has increased or
decreased with the set quantity (SETUP 94). Pulse output R2 will send a 0 for
increase or 1 for decrease.

FW_F115P_v1702_02_EN
Page 18
WIDTH
92
The pulse width determines the time that the output will be active; in other words
the pulse duration. Value “zero” will disable the pulse output.
The pulse signal always has a 50% duty cycle, hence the minimum time between
the pulses is equal to the pulse width setting. If the frequency should go out of
range –when the flow rate increases for example –an internal buffer will be used
to “store the missed pulses”: As soon as the flow rate slows down, 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 its range!
DECIMALS
93
This setting is used to set the amount of digits behind the decimal point for the
amount.
AMOUNT
94
A pulse will be generated every time a certain quantity is added to the total. Enter
this quantity here while taking the decimals for pulse into account.
