1 INTRODUCTION
1.1 SYSTEM DESCRIPTION
Functions and features
The flow computer, model F127-P is a microprocessor driven instrument for the calculation of
differential flow measurement applications using flow equations for liquids. This product has been
designed with a focus on:
two multi-purpose pulse inputs;
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 and temperature input
This manual describes the unit with a pulse input from the flowmeter. The F127-P has also a PT100
temperature input. 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 F127-P.
To power the sensor, several options are available.
Standard output
Pulse output to transmit a pulse that represents a totalized quantity as programmed.
Linear (0)4-20mA or 0-10V analog output to represent the actual calculated differential flow rate
as programmed. The (0)4-20mA or 0-10V signal limits can be tuned.

FW_F127PELTP_v1702_02_EN
Configuration
The F127-P is designed for use in many types of applications. For that reason, a setup menu is
available to program the F127-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.
Backlight
A backlight is available as an option. The brightness can be tuned as desired (requires power supply
type PD/PF/PM). For battery and loop powered applications the backlight will not function.
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, extended measurement range for PT100, panel-mount,
wall-mount and weather-proof enclosures, flame proof enclosure and LED backlight.
2 OPERATIONAL
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.

2.2 OPERATOR INFORMATION AND FUNCTIONS
In general, the F127-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 F127-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 calculated differential flow rate and calculated differential total
This is the main display information of the F127-P. After the selection of any other information, it
will always return to this main display automatically. 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, then the flow rate value is too high to be shown. The arrows indicate
the increase/decrease of the flow rate trend. If the consumption is very low, it might be that a
stable low flow rate and total is shown; this is due to the settings of the F127-P.
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.
Type IB: When a Normally Closed (NC) contact is used, the local clear total function is disabled
and a clear total is only possible with the external reset command.
Display calculated differential 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.
Display line temperature and calculated flow rate INLET / OUTLET
When the SELECT/key is pressed twice, the actual INLET / OUTLET temperature is shown at
the top line of the display. At the bottom line, the calculated INLET / OUTLET flow rate is shown
together with the engineering units for flow rate and temperature
Range error
As soon as the input value is out of the calibrated PT100 measurement range, the alarm indicator
shows. When the SELECT/key is pressed a few times, the alarm code is shown in the alarm
display. This alarm is also activated at a wire break or faulty sensor.
(standard range -100°C - +200°C or extended range, type ZV: -200° - +800°C).
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.
Fig. 4: Low-battery alarm (typical)

3.1.2 EXPLANATION OF SETUP-MENU 1 - TOTAL-A
1
TOTAL-A
11
unit
This setting is used to select the engineering unit for the indication of the 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.
12
decimals
This setting is used to set the amount of digits behind the decimal point for the
(accumulated) total indication (A and B).
13
K-factor
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.
14
decimals K-factor
This setting is used to set the amount of digits behind the decimal point for the
K-Factor (A).

Page 12
FW_F127PELTP_v1702_02_EN
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.
2
FLOW RATE-A
21
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

This setting is used to set the amount of digits behind the decimal point for the
flow rate indication (A and B).
24
K-factor
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.

filter
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.

This setting is used to calculate the flow rate by counting the number of pulses
within a certain time, for example 1 second. The longer the time the more
accurate the flow rate will be.
This setting does influence the update time for the analog output directly. If the
output response is too slow, decrease the number of pulses.
The shorter the update time, the higher the power consumption of the unit will
be (important for battery powered applications).

The backlight brightness can be adjusted from 0% (off) to 100% (full brightness)
in steps of 20%.
When the F127-P is only loop powered, the backlight is disabled. An external
power supply is required to supply the backlight.
53
measurement
To solve undesired display readings during low or even negative consumption
situations, four different measurement methods have been implemented. Note
that the selection does influence the analog output value (ref. flow rate) as well.
bi-directional
Shown flow rate: positive and negative.
Shown total: increases or decreases.
not negative
Shown flow rate: only positive or zero.
Shown total: increases or decreases.
threshold
Shown flow rate: as soon as the flow rate is lower than SETUP 54 or negative,
zero flow rate is shown.
Shown total: as soon as the flow rate is lower than SETUP 54 or negative,
totalization will stop.

Page 14
FW_F127PELTP_v1702_02_EN
stationary
Shown flow rate: as soon as the flow rate is lower than SETUP 54 or negative,
the stationary flow rate (SETUP 54) is shown.
Shown total: as soon as the flow rate is lower as SETUP 54 or negative,
stationary totalization (SETUP 55) will be activated. However, if the value of
setting 54 is zero, totalization increases or decreases.
54
stationary flow rate
Enter here the flow rate according SETUP 53: threshold or stationary. The time
and measuring units are according to flow rate SETUP 21 and 22.
threshold
Flow rate zero is shown as soon as the flow rate will be lower as this setting.
stationary
As soon as the flow rate is lower as this setting, this flow rate is shown.
If the flowmeters do not generate pulses, the flow rate shows zero.
55
stationary total
Enter here a flow rate per hour according to SETUP 53 –‘stationary’.
The measuring unit is according to TOTAL (A and B) - SETUP 11.
This flow rate is converted to a total which will be used as long as the flow rate is
lower as SETUP 54.
If the flowmeters do not generate pulses, the totalization will stop.
This function is disabled if value zero has been entered.
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 F127-P has several smart power management functions to extend the battery life time
significantly. Two of these functions can be set.

POWER MANAGEMENT
61
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.
62
battery mode
The F127-P has two modes: operational or shelf.
After "shelf" has been selected, the F127-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 F127-P again, press the SELECT/key two times.

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

FORMULA
91
equations type
This setting shows the formula. The type EL stands for Equations Liquid - flow
computer for corrected liquid volume
The formula used: Qnormal = Q * (1 + (Tnormal - T)) where:
Qnormal : calculated volume at reference conditions
Q: measured volume
: thermal expansion coefficient
Tnormal : reference temperature
T: measured temperature
92
thermal expansion
coefficient
Enter here the thermal expansion coefficient for the liquid used. The value to
be entered has to be multiplied with 1000. The decimal position is fixed but
cannot be shown: x,xxxxxx.
With the default value of 0.000000 the volume correction is disabled.
Examples: Calculation of the thermal expansion coefficient
for water is 0,00031 per K. Enter: 0310000.
for petrol is 0,00110 per K. Enter: 1100000.
93
normal temperature
Enter here the reference temperature Tnormal in degrees Kelvin (K). In most
applications, the volume has to be calculated at 15°C which is 288,15 K.
3.1.11 EXPLANATION OF SETUP-MENU A - 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.
A
ANALOG OUTPUT
A1
output
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.
A2
rate-min
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.
A3
rate-max
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.
A4
cut-off
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.

Page 17
FW_F127PELTP_v1702_02_EN
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
A5
tune-min
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.
A6
tune-max
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

store the new value.
If required, you can program the analog output 'up-side-down'. The (0)4mA or 0V

B
PULSE
B1
mode
The unit has three scaled pulse output modes. This functionality drives two pulse
outputs which, depending on the mode, can be used as follows:
signed
On pulse output R1 a pulse will be send when the total has increased or
decreased with the set quantity (SETUP B4). Pulse output R2 will send a 0 for
increase or 1 for decrease.
not negative
On pulse output R1 a pulse will be sent when the total has increased with the set
quantity (SETUP B4). On pulse output R2 the sign of the flow rate will be send
(positive=0, negative=1).

Page 18
FW_F127PELTP_v1702_02_EN
separated
On pulse output R1 a pulse will be sent when the total has increased with the set
quantity (SETUP B4). On pulse output R2 a pulse will be sent when the total has
decreased with the set quantity (SETUP B4).
B2
width
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!
B3
decimals
This setting is used to set the amount of digits behind the decimal point for the
amount.
B4
amount
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.
