1 INTRODUCTION
1.1 SYSTEM DESCRIPTION
Functions and features
The ratio monitor / totalizer model F114-P is a microprocessor driven instrument designed to
calculate, show and monitor the ratio between two flows as well as showing the flow rates and the
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, alarm and communication outputs.
Flowmeter input
This manual describes the unit with a pulse input from the flowmeters. 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 can be
connected to the F114-P. To power the sensor, several options are available.
Standard outputs
▪Max. three configurable alarm outputs: high-, low-, high-high- or low-low-ratio alarm. Switched
as long as the ratio is too high or too low.
▪Linear (0)4-20 mA or 0-10 V analog output to represent the actual ratio or flow rate as
programmed. The (0)4-20 mA or 0-10 V signal limits can be tuned.

Configuration of the unit
The F114-P is designed for use in many types of applications. For that reason, a setup menu is
available to program the F114-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 saved 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.

•This device may only be operated by persons who are authorized and trained by the
operator of the facility. All instructions in this manual are to be observed.
•Take careful notice of the "Safety rules, instructions and precautionary measures" in the
front of this manual.
2.2 CONTROL PANEL
The control panel has three keys. The following keys are available:
Fig. 2: Control panel.
Functions of the keys
PROG-key
This key is used to program and save new values or settings.
The PROG-key is also used to gain access to SETUP-level; please read chapter 3.
SELECT-key
This key is used to SELECT the displayed information, like accumulated total and flow
rate.
CLEAR-key
This key is used to CLEAR the value of total.
2.3 OPERATOR INFORMATION AND FUNCTIONS
In general, the F114-P will always function at Operator level. The information displayed is dependent
upon the SETUP-settings. The signal from the connected sensor is processed by the F114-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.
Fig. 3: Example of display information during process.
For the Operator, the following functions are available:
▪Display ratio
The ratio is calculated by measuring the flow A and flow B. The shown ratio can indicate:
-the actual flow rate of the additive compared to the flow rate of the main flow, or
-the actual flow rate of the additive compared to the total flow (summed additive + main flow).
The arrows indicate the increase/decrease of the ratio trend.

FW_F114-P_M_v2201-01_EN.docx
Page 9
▪Display flow rate
When enabled in the setup menu, the display shows the flow rate only. When you press the
select key, the total shows momentarily.
When "-------" is shown, then the flow rate value is too high to be shown. The arrows indicate
the increase/decrease of the flow rate trend.
▪Display total
The actual total quantity of each flowmeter is shown after pressing select several times.
▪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.
▪Programming the ratio alarm values
Setting the alarm values in Operator-mode may be disabled in the setup menu
When you press the SELECT/key several times, the ratio alarm values are shown:
•low-low ratio alarm (LL, 1-0.010 for example)
•low ratio alarm (LO, 1-0.2 for example)
•high ratio alarm (HI, 1-1.0 for example)
•high-high ratio alarm (HH, 1-1.2 for example)
To change the alarm value, the following procedure must be executed:
1. Press the PROG/ENTER key to access the submenu.
2. Use the SELECT/key to increase the digit. Use the CLEAR/key to go to the next
number.
3. Confirm the new alarm value by pressing ENTER. If you do not press the PROG/ENTER key
to confirm, your selection is not saved.
Fig. 4: Examples displayed information during programming high ratio alarm level: as
percentage (left) and as ratio (right).
▪Ratio alarm
When the actual ratio is outside the allowed range, an alarm message will be shown indicating
the type of alarm. The alarm is terminated automatically as soon as the ratio is within its range
again.
▪Low-battery alarm
When the battery voltage drops, the "low-battery" icon will be displayed continuously. The battery
MUST be replaced shortly after!
The remaining lifetime after the first moment of indication is generally several days up to some
weeks. See paragraph 6.3 for further information on battery replacement.

TOTAL A
1.1
UNIT
This setting is used to select the engineering unit for the indication of the
differential total, total (A and B) and the pulse output.
When you change the engineering unit, you must recalculate and
reprogram the K-factor for the total. When you recalculate and reprogram
the K-Factor, the history for total is not correct anymore, because the total
is not recalculated. For future reference, best practice is to make a note of
the total before you program the recalculated K-Factor.
1.2
DECIMALS
This setting is used to set the amount of digits behind the decimal point for
the total indication (A and B).
1.3
K-FACTOR
This setting is used to set the K-Factor for the total for flowmeter 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 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 total is
not correct anymore, because the total is not recalculated. For future
reference, best practice is to make a note of the total before you program
the recalculated K-Factor.
1.4
DECIMALS K-
FACTOR
This setting is used to set the amount of digits behind the decimal point for
the K-Factor (A).

3.3.3 MENU 2 - FLOW RATE
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.

FLOW RATE A
2.1
UNIT
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.
2.2
TIME
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.
2.3
DECIMALS
This setting is used to set the amount of digits behind the decimal point for
the flow rate indication (A and B).
2.4
K-FACTOR
This setting is used to set the K-Factor for the flow rate of flowmeter 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 m3. A more accurate K-Factor
(more decimals, as set in decimals K-Factor) allows for a more accurate
operation of the system.
2.5
DECIMALS K-
FACTOR
This setting is used to set the amount of digits behind the decimal point for
the K-Factor (A).
2.6
PERIOD
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 flowrate 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.

POWER MANAGEMENT
8.1
LCD NEW
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.
8.2
BATTERY MODE
The F114-P has two modes: operational or shelf.
After "shelf" has been selected, the F114-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 F114-P again, press the SELECT/key two times.

The (0)4 mA or 0 V value can be tuned precisely with this setting. The
initial minimum analog output value is (0)4 mA or 0 V. 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 4 mA (0 mA or 0 V). 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)4
mA or 0 V then represents the maximum flow rate or ratio and the 20 mA
