The pulse length can be set as desired with a maximum frequency of 500Hz.
•Unscaled frequency output for retransmission of the incoming pulses as robust square wave
forms.
•Configurable linear 4-20mA isolated analog output with 12-bits resolution representing the actual
compensated flowrate. Flowrate levels as well as the minimum and maximum signal output can
be tuned.
Configuration
The E126-P-EL has been designed to be implemented in many types of applications. For that
reason, a SETUP-level is available to configure your E126-P-EL according to your specific
requirements.
It includes several important features, such as K-Factor, measurement units, signal selection etc.
All settings are stored in an EEPROM memory and will not be lost in the event of a power failure or a
drained battery.
To extend the battery-life time, please use of the power-management functions as described in
chapter 3.
Display information
The E126-P-EL has a large LCD with all kinds of symbols and digits to display measurement units,
status information, trend-indication and key-word messages.
Flowrate and totals can be displayed either with the 11 small 7mm (0.28”) digits or with the 7 large
12mm (0.47”) digits. Additionally, the E126-P-EL has an analog speedometer to show the actual
compensated flowrate.
Backlight
A backlight is standard available. The intensity can be set as desired (externally powered only).
The backlight can even be used in battery powered applications: it will be switched on, at a fixed
intensity, during a limited period of time and will switch off automatically, 3 seconds after a key
touch.
For loop powered applications only, the backlight will not come on because of limited power.
Options
The following options are available: full Modbus communication RS232/485 or USB (also battery
powered), mechanical relay outputs, power- and sensor-supply options.

2 OPERATIONAL
2.1 GENERAL INFORMATION
This chapter describes the daily use of the E126-P-EL. This instruction is meant for users /
operators.
•The E126-P-EL may only be operated by personnel 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 optical keys are operated through the glass. The following keys are available:
Fig. 2: Control panel, optical keys
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
flowrate.
CLEAR-key
This key is used to CLEAR the value of total.
The CLEAR-key also provides access to historical day totals.
Use of optical keys
The optical keys are designed to operate stable and will not be activated when the glass surface is
not clean. However, keep the glass surface clean to avoid false key activations (false activations
reduce battery lifetime). Also do not mount objects within 100mm in the front of the product (shiny
surfaces could cause false activations). It is not necessary to touch the glass for activation.
Activating by touching the clean glass surface normally also works fine, but in case of detection
problems try not to touch the glass.
Unlock / lock optical keys
To prevent any undesired operation of the optical keys and to save battery power, an automatic key-
lock function is implemented. This function can be disabled at SETUP-menu Others.

Page 8
FW-E126-P-EL-M_v0203_03_EN.docx
When the optical keys are locked, the key lock symbol is shown at the top of the display as
shown below.
Fig. 3: Control panel, disable optical keys
To unlock the optical keys, the operator need to ‘activate’ the keys by pressing any of the keys for
about 1 to 2 seconds. After activation, the backlight will light up (if enabled) and the display will hint
the following sequence of keys for the operator to briefly touch after each other:
PROG –SELECT –CLEAR
When the sequence is successfully executed, the optical keys will be unlocked and the key lock
symbol will disappear.
The optical keys are automatically locked after 30 seconds of inactivity. However, to lock the optical
keys manually, touch the PROG and CLEAR key simultaneously for 3 seconds.
Enable or disable optical keys with on-off switch
Directly below the optical keys an on-off switch is located to enable or disable the optical keys. Move
this switch to the right to enable or to the left to disable the optical keys. When the optical keys are
disabled the key lock symbol will appear in the display and operation of the unit can only be
performed with the mechanical push buttons.
Fig. 4: Control panel, ON/OFF optical keys
For battery powered applications it is recommended to switch off the optical keys when
possible to save on power consumption significantly.
Push button operation
Next to the three optical keys also three push buttons are available when the cover is removed.
Make sure the key lock is active before removing the cover to prevent unwanted actions.
On the side of the collar of the display three black mechanical push buttons are present in the same
order as the optical keys, PROG –SELECT –CLEAR. They operate in the same manner as the
optical keys, and when pressed, the optical keys are disabled for 30 seconds to prevent any
interference.

2.3 OPERATOR INFORMATION AND FUNCTIONS
Check the key lock and unlock before operation
Unlock the optical keys as described before.
By default, the E126-P-EL will act at Operator level. The information displayed is dependent upon
the SETUP-settings. Signals generated by the connected flowmeter and sensors are measured by
the E126-P-EL in the background. The display values are however updated depending on the
selected refresh rate. After pressing a key, the display will be refreshed 8 times per second, after 30
seconds it will return to the selected setting.
Fig. 6: Example of display information during process
For the Operator, the following functions are available:
Display process values
On the main screen, the primary process values of the E126-P-EL are shown. By default, Total is
shown on the upper-line of the display and Flowrate on the bottom line.
In the configuration settings for Display, this can be changed to show only Flowrate on the large
12mm digits or to show Total and Accumulated Total simultaneously. When Flowrate is shown, the
arrows ▲▼ indicate the trend (increase or decrease) of the flowrate.
By pressing the SELECT-key, the operator can scroll through the screens showing the various
process values. After 30 seconds of inactivity, the display will automatically return to the main
screen.
The following table shows the available information:

(i.e. temperature compensated)
•When the toggle function is enabled in the SETUP-menu Display, temperature
information is shown on the bottom line of the main screen, alternating with the normal
information shown on the display.

Page 10
FW-E126-P-EL-M_v0203_03_EN.docx
Clear total
The value for Total can be cleared and reset to zero. This action does not influence the value of
Accumulated Total or Current Day Total.
To clear Total, press the CLEAR-key when Total is shown on the display and the display will show
the flashing text “PUSH CLEAR”. When the CLEAR-key is pressed a second time, Total is set to
zero. To avoid clearing Total at this point, press the PROG- or SELECT-key or wait for 20 seconds.
•If the ‘Total CLEAR password’ is set in the configuration settings for Total, the operator is
asked to enter the password before the “PUSH CLEAR” text is shown. The correct
password needs to be entered before Total can be cleared. (See paragraph 3.2.3.)
•The IB option (external reset) allows clearing of total via an external pushbutton. This
clear action operates in parallel with the clear action via the control panel but does not
require any extra confirmation or password. When the external connection is permanently
closed, Total still counts but the ”Clear Total” function via the control panel is disabled.
Display flowrate
Internally, the flowrate is calculated up to 8 times a second, To obtain a readable value, the flowrate
shown on the display is updated once every second. Flowrate is shown, based on the configuration
settings for Flowrate, with the configured number of decimals. The configured unit and time unit are
indicated on the bottom line of the display.
When “-------“ is shown, the flowrate value is too high to be displayed. The arrows ▲and ▼indicate
the trend (increase or decrease) of the flowrate.
Display line temperature
Several times a second, the input value of the temperature sensor is measured. Temperature is
calculated based on the configuration settings for Temperature and shown on the display with the
configured number of decimals and (display) unit.
Display total and accumulated total
A resettable Total and non-resettable Accumulated Total are available. The Total value can count up
to 9.999.999 before rolling over to zero; the Accumulated total can count up to 99.999.999.999
before rolling over.
The unit and number of decimals are displayed according to the configuration settings for Total.
Display current day total and previous day total
Two additional non-resettable totals are available: Current Day Total and Previous Day Total. These
totals are shown in the same unit and decimals as set in the configuration settings for Total.
At a specific time of day, the Current Day Total is copied to the Previous Day Total after which the
measurement of Current Day Total is restarted (reset to zero). The moment at which this action is
performed is called 'contract hour'. The contract hour can be configured in the configuration settings
for Total in steps of 1 hour.
•‘Current Day Total’ is often referred to as ‘Daily Total’.
•The Current Day Total shows the quantity that is measured since last contract hour, and
is a ‘running’ value.
•The Previous Day Total shows the total quantity that was measured the day before, and
is a ‘fixed’ value.
•Both Current Day Total and Previous Day Total cannot be reset manually.
Display historical day totals
Besides directly reviewing the Current Day Total and Previous Day Total, a list of the last 15
Previous Day Totals can be reviewed. To enter the list, press the CLEAR-key for 3 seconds. Use the
SELECT- and CLEAR-key to scroll up and down through the list of Previous Day Totals. The
number that is displayed on the left side of the bottom line indicates the age of the shown Previous
Day Total, in days. Note that the entry with age ‘00’ represents the (running) Current Day Total.
To return to the main display information again, press the PROG-key during 3 seconds or wait for 3
minutes.

Page 11
FW-E126-P-EL-M_v0203_03_EN.docx
Display speedometer flowrate
Along the edge of the display, a percentage based impression of the actual flowrate is shown. The
speedometer consists of 20 segments which run from 0 to 100% in increments of 5%. This function
can be enabled or disabled in the SETUP-menu Display.
2.4 OPERATOR ALARMS
Low-battery alarm (Type PB only)
During operation the battery voltage drops. When the battery voltage becomes too low, the battery
indicator comes on to show that the operation and indication become less reliable. When the battery
indicator is on, install a fresh and new battery (as soon as possible) to keep a reliable operation and
indication.
Fig. 7: Example of low-battery alarm
Range error
As soon as the input value of the temperature sensor is out of the calibrated measurement range,
e.g. because of a wire break or a faulty sensor, the alarm indicator shows, and ‘range error’is shown
on the temperature screen. When the SELECT-key is pressed a few times, the exact alarm code is
shown in the alarm display.

3.3.2 EXPLANATION OF SETUP-MENU 1 –TOTAL
•First setup the flowmeter at SETUP-menu 4 - Flowmeter. It has a direct influence on the
settings for Total.
•Change of the type of flowmeter unit (SETUP 4.2 and SETUP 4.3) will cause the Total
unit to jump to the default setting of the new flowmeter unit type.
•When a different unit is selected, the actual total values are NOT recalculated!
1
TOTAL
1.1
UNIT
This setting determines the measurement unit for (accumulated) total
and the scaled pulse output. The measurement units which are
available, are controlled from the UNITS which are selected in the
flowmeter menu.
AUTO-VOL: L –m3 –US gal –I gal –cf –Oil bbl –nL –nm3;
AUTO-MAS: kg –ton –US ton –lb;
HAND: l –m3 –US gal –I gal –cf –Oil bbl –kg –ton –
US ton –lb –nL –nm3 –---- (no unit).
1.2
DECIMALS
The decimal point determines for Total and accumulated Total the
number of digits following the decimal point.
The following can be selected:
0, 0.1, 0.02, 0.003
The next menu item can be modified only if the automatic unit
conversion in SETUP 4.2, Flowmeter-units, is set to Hand. Else,
the display will show “AUTO”.
1.3
K-FACTOR
With the Total K-Factor, the flowmeter pulse signals are converted to
a total unit. The Total K-Factor is based on the number of pulses
generated by the flowmeter per selected measurement unit
(SETUP 1.1). The more accurate the Total K-Factor, the more
accurate the functioning of the system will be.
After pressing PROG, the decimal point will be flashing. The decimal
position can be changed now by pressing the ▲-key.
1.4
FACTOR-X
This setting determines the multiplication factor of Total and
Accumulated Total and is also applicable to the Current and Previous
Day Totals. This functions allows to show up to 3 digits more of the
Total/accumulated Total. The amount shown is a rounded number.
The following can be selected:
x1 –x10 –x100 –x1000
1.5
CLEAR PASSWORD
Clearing Total by the Operator can be password protected.
This protection is disabled with value 000 (zero).
A 3 digit password can be programmed, for example 123.
1.6
CONTRACT HOUR
The contract hour can be set in steps of 1 hour to any hour of the day.
When the system clock reaches the time set in the contract hour, the
Current Day Total is copied to the Previous Day Total, after which the
measurement of the Current Day Total is restarted (reset to zero).
Without type ZL –Data logging, the clock will be interrupted in case
of a power-down. When the unit is powered up again, the display will
immediately ask the operator to enter the correct system time.
Without an initialized clock, all measurements and calculations are
performed as normal. However, when the Daily Total feature is
enabled, the detection of contract hour and updating the Current and
Previous Day Totals will not be done at the correct time.
1.7
CURRENT DAY-TOTAL
This setting shows the amount of product totalized, since the last
contract hour. This a ‘running’ totalizer and cannot be reset to zero.

Page 18
FW-E126-P-EL-M_v0203_03_EN.docx
1.8
PREVIOUS DAY-TOTAL
This setting shows the amount of product totalized, before the last
contract hour. This totalizer cannot be reset to zero.
See chapter 2 for information on reviewing more historical day totals.
3.3.3 EXPLANATION OF SETUP-MENU 2 –FLOWRATE
•First setup the flowmeter at SETUP-menu 4 - Flowmeter. It has a direct influence on the
settings for Flowrate.
•Change of the type of flowmeter unit (SETUP 4.2 and SETUP 4.3) will cause the flowrate
unit to jump to the default setting of the new flowmeter unit type.
•Changes to SETUP 2.1 Unit, SETUP 2.2 Time unit and SETUP 2.3 Decimals have an
effect on the analog output settings of SETUP 6.2 Rate Min and SETUP 6.3 Rate Max
and the display setting of SETUP 3.5 Ratespan.
Therefore it is best practice to first determine the required settings for the flowrate!
2
FLOWRATE
2.1
UNIT
This setting determines the measurement unit for flowrate. The
flowrate unit that can be chosen depends on the type of flowmeter
unit (volumetric or mass) set at SETUP 4.2.
The following can be selected:
AUTO-VOL: mL - L - m3 - US GAL - I GAL - cf - Oil bbl - nL -
nm3 - scf
AUTO-MAS: mg - g - kg - ton - lb - US ton
Hand: mL - L - m3 - US GAL - I GAL - cf - Oil bbl - nL -
nm3 - scf - mg - g - kg - ton - lb - US ton - rev -
P - ---- (no unit)
2.2
TIME
The flowrate can be calculated per /sec - /min - /hour - /day.
2.3
DECIMALS
This setting determines for flowrate the number of decimals.
The following can be selected:
0, 0.1, 0.02, 0.003
The next menu item can be modified only if the automatic unit
conversion in SETUP 4.2, Flowmeter-units, is set to Hand.
Else, the display will show “AUTO”.
2.4
K-FACTOR
With the Flowrate K-factor, the flowmeter pulse signals are converted
to a flowrate unit. The Flowrate K-factor is based on the number of
pulses generated by the flowmeter per selected measurement unit
(SETUP 2.1).
The more accurate the K-factor, the more accurate the functioning of
the system will be.
After pressing PROG, the decimal point will be flashing. The decimal
position can be changed now by pressing the ▲-key.
2.5
FILTER
This setting is used to stabilize the flow rate reading. With the help of
this digital filter a more stable but less actual reading 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. In practice it is best to use trial and error to find the
best setting for your application.
2.6
PERIOD
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).

DISPLAY
3.1
FUNCTION
This setting determines which information is shown on the main
screen. The function can be set to indicate total, flowrate or
accumulated total.
•When “total” is selected, total is displayed with the large 12mm
(0.47”) digits and flowrate is displayed with the 7 mm (0.28”) digits
simultaneously.
•When “flowrate” is selected, only flowrate will be displayed with
the large 12mm (0.47”) digits together with its measuring unit.
•When "accumulated total" is selected, total is displayed with the
large digits and accumulated total is displayed with the small
digits simultaneously.
•When SELECT is pressed on the main screen, the operator can
scroll through the various process values. See chapter 2 for more
information on operator information and functions.
3.2
DAY TOTALS
A basic data log function is available to register Current Day Total and
Previous Day Total. This function sets the availability at operator
level:
•Off: Current Day Total and Previous Day Total are not available.
•Operator: Current Day Total and Previous Day Total are available
at operator level by pressing the SELECT key several times.
At SETUP-level, they can be reviewed at SETUP 1.7 and
SETUP 1.8.
•Hidden: Current Day Total and Previous Day Total are only
available at SETUP 1.7 and SETUP 1.8.
When this function is enabled, a list of the last 15 historical day totals
is available and can be reviewed from operator level.
Please see paragraph 2.3 for more information.
3.3
TOGGLE
By enabling the display toggle function, temperature information is
shown on the main screen (see chapter 2), alternating with the normal
information shown on the bottom line of the display.
The following can be selected:
enable –disable
When battery powered, the user can expect reliable measurement
over a long period of time. The E126-P-EL has several smart power
management functions to extend the (optional) battery life time
significantly next to permanently disabling the optical keys. The
following functions can be set:
3.4
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 output signals are generated in the normal way.
The following can be selected:
FAST –1 sec –3 sec –15 sec –30 sec –OFF
When “off” is selected the display will switch off automatically.
When an update rate other than “fast” is selected, pressing a key will
switch the update rate to “fast” for 30 seconds. After this time, the
display will return to the configured update rate (or switch off).
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 temporarily turn on after
touching one of the keys and turn off automatically after 30 seconds.

3.5
BACKLIGHT
The unit is provided with a backlight. The backlight brightness can be
adjusted from off (0) to a 100% in steps of 20%.
The following can be selected:
0% - 20% - 40% - 60% - 80% - 100%
For battery powered units the brightness is not adjustable.
When the unit is only loop powered it cannot make use of the
backlight. In that case an external supply is required.
3.6
BARGRAPH
The unit has a speedometer display which offers a quick impression
of the actual flow rate. This graph on the display can be switched on
or off. The following can be selected:
enable –disable
3.7
RATESPAN
With Ratespan the range of the speedometer can be set. The display
shows 0 –100 with 20 blocks so each block is 5% of the 100% range
set here. The following can be selected:
0000000 –9999999
The number of decimals displayed depends upon SETUP 2.3.
3.3.5 EXPLANATION OF SETUP-MENU 4 –FLOWMETER
To simplify the configuration of the Flowmeter, total and flow rate settings, the E126-P-EL is
equipped with an automatic unit conversion feature. This avoids different K-Factor calculations for
Total and Flowrate and all configuration it done inside the Flowmeter menu. To use the automatic
unit conversion, you only need to enter the (average) K-Factor and the related measurement unit.
These can be found on the test/calibration certificate that came with your flowmeter.
For a detailed description and tutorials on the automatic unit conversion function, please refer to our
website or your supplier.
To setup the automatic unit conversion, follow this procedure:
•SETUP 4.1: Select the correct type of flow meter signal
•SETUP 4.2: Select the type of measurement unit used on the certificate: volume or mass
•SETUP 4.3: Select the measuring unit according to the certificate
•SETUP 4.4: Enter the (average) K-factor shown on the certificate.
•SETUP 1.1: Select the desired measuring units for (accumulated) Total.
•SETUP 2.1: Select the desired measuring units for Flow rate
The automatic unit conversion can handle either volume or mass units. For measurement units
which are not supported, for example ‘revolutions’ or the use of volume and mass units
simultaneously, the automatic unit conversion can be set to ‘Hand’, allowing total and flowrate to be
configured independently.
Example: Calculating the K-factor.
To manually calculate the K-factor to enter for total or flowrate, follow this example:
Assume that the flowmeter generates 65.231 pulses per US gallon and the required measurement
unit is cubic foot / ft3. A cubic foot consists of 7.48052 gallon which implies 487.9618 pulses per
cubic feet. So, the K-Factor to enter is 487.9618.
