1. INTRODUCTION
1.1. SYSTEM DESCRIPTION OF THE E112-P
Functions and features
The flowrate / totalizer model E112-P is an explosion proof microprocessor driven instrument designed to
to linearize the flowmeters flow curve and display the flowrate, total and accumulated total.
The E-series product line has been designed with a focus on:
User-friendliness: operation through the glass without removing the cover.
Mounting flexibility: multiple solutions for sensor mounting, including 1” NPT or M25 bottom entry as
well as suitable for wall or pipe mount applications.
Ruggedness for harsh surrounding: not just designed to be explosion proof.
Usability: wide operational temperature, high ingress protection rating and international certification.
Installation friendly design: spacious cabling area, plug and play cable connection and easy removable
electronic module.
Cost effectiveness: aluminum enclosure with high quality industrial two component coating.
Suitability for offshore applications: stainless steel 316L enclosure version.
Ease for the Operator: functional information and identical operation as all F / D / N –series of Fluidwell.
Ability to process any type of sensor signals,
Multiple power supply options to suit any application, including long-life battery supply.
Transmitting possibilities with analog / pulse and communication (option) outputs.
Flowmeter input
This manual describes the unit with a pulse type input from the flowmeter "-P version". Other versions,
(0)4-20mA or 0-10V flowmeter signals, are pending.
One flowmeter with a passive or active pulse, Namur or sine wave (coil) signal output can be connected to
the E112-P. To power the sensor, several options are available.

Standard outputs
Configurable pulse output: a scaled pulse representing a certain linearized total quantity. Maximum
frequency 500Hz. The pulse length can be set as desired.
Configurable linear 4-20mA isolated analog output with 12-bits resolution representing the actual
linearized flowrate. Flowrate levels as well as the minimum and maximum signal output can be tuned.
Configuration of the unit
The highly praised configuration structure is identical to any other Fluidwell product while the clear texts
reduce potential mistakes. Once familiar with one product, you are able to control them all, often without a
manual: if you know one – you know them all.
The E112-P has been designed to be implemented in many types of applications. For that reason, a
SETUP-level is available to configure the E112-P according to your specific requirements.
SETUP includes several important features, such as K-factors, 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 (option), please make use of the power-management functions as described
in chapter 3.2.3.
Display information
The unit has a large transflective LCD with all kinds of symbols and digits to display measuring units, status
information, trend-indication and key-word messages.
Flowrate and totals can be displayed either with the small 7mm (0.28”) (11) digits or with the large 12mm
(0.47”) (7) digits. The E112 shows the operator a speedometer reflecting the actual flowrate.
A backup of the total and accumulated total in EEPROM memory is made every minute.
Backlight
A backlight is standard available while the brightness can be tuned as desired (externally powered only).
The backlight can even be used in battery powered applications: it will be switched on during a limited
period of time and will switch off automatically within 30 seconds after the key touch.
For loop powered applications only, the backlight will not function.
Options
The following options are available:
•Full Modbus communication RS232/485 (also battery powered),
•Mechanical relay,
•Power- and Sensor-supply.

3.4. EXPLANATION OF SETUP-FUNCTIONS
1 - TOTAL
UNIT
1.1 SETUP – 1.1 determines the measurement unit for total, accumulated
total and pulse output. The following units can be selected:
L - m3- kg - lb. - GAL - USGAL – IGAL - bbl - _ (no unit).
Alteration of the measurement unit will result in also making changes to
related settings to keep a match. Please note that the K-factor has to be
adapted as well; the calculation is not done automatically.
DECIMALS
1.2 The decimal point determines for total and accumulated total the number
of decimals. The following can be selected:
0000000 - 111111.1 - 22222.22 - 3333.333
K-FACTOR
1.3 With the K-factor, the flowmeter pulse signals are converted to a total unit.
The K-factor is based on the number of pulses generated by the
flowmeter per selected measurement unit (SETUP 1.1), 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.
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 – 1.3:
"2481300" and for SETUP – 1.4 - decimals K-factor "3".
Example 2: Calculating the K-factor.
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 – 1.3: "6523100" and for SETUP –
1.4 decimals K-factor "6".
DECIMALS K-FACTOR
1.4 This setting determines the number of decimals for the K-factor entered.
(SETUP 1.3). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this setting influences the total K-factor. (i.e. the position
of the decimal point and thus the value given)
This setting has NO influence on the displayed number of decimals for
total (SETUP 1.2)!
MULTIPLY FACTOR
1.5 This setting determines the scale factor of the Total. This makes it
possible 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

FW-E112-P-MAN-EN_v0101_08
Page 16
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.
UNIT
2.1 SETUP – 2.1 determines the measurement unit for flowrate.
The following units can be selected:
mL - L - m³ - mg - g - kg - ton- GAL - bbl - lb - cf - rev - none - scf - nm³ - nL - P
Alteration of the measurement unit will NOT affect 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
2.2 The flowrate can be calculated per second (/SEC), minute (/MIN), hour
(/HR) or day (/DAY).
Note: Changes to SETUP 2.2 Time unit has an effect on the settings of
SETUP 6.2 Rate Min and SETUP 6.3 Rate Max and SETUP 3.5
Ratespan. Don’t forget to update these settings after a change.
DECIMALS
2.3 This setting determines for flowrate the number of decimals.
The following can be selected:
00000 - 1111.1 - 2222.22 - 3333.333
Note: Changes to SETUP 2.3 Decimals will also change the decimal
setting of SETUP 6.2 Rate Min and SETUP 6.3 Rate Max and
SETUP 3.5 Ratespan. Therefore it is wise to first determine the
required decimals for the flowrate.
K-FACTOR
2.4 With the K-factor, the flowmeter pulse signals are converted to a flowrate
unit. The K-factor is based on the number of pulses generated by the
flowmeter per selected measurement unit (SETUP 2.1), for example per
liter.
The more accurate the K-factor, the more accurate the functioning of the
system will be. For examples read SETUP 1.3.
Alteration of the K-Factor will have consequences for Operator and
SETUP-level values!
DECIMALS K-FACTOR
2.5 This setting determines the number of decimals for the K-factor
(SETUP 2.4). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Note: SETUP 2.5 influences the flowrate K-factor setting only.
This setting has NO influence on the displayed number of
decimals for "Flowrate" (SETUP 2.3)!
CALCULATION
2.6 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
2.7 With this setting, a minimum flow requirement threshold is determined, if
during this time less than XXX-pulses (SETUP 2.6) are generated, the
flowrate will be displayed as zero.
The cut-off time has to be entered in seconds - maximum time is 999.9
seconds (about 15 minutes).
3 - DISPLAY
FUNCTION
3.1 The large 12mm (0.47”) digits can be set to display 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 while total will be
displayed after pressing SELECT.
When "accumulated total" is selected, total is displayed with the large
12mm (0.47”) digits and accumulated total is displayed with the 7 mm
(0.28”) digits simultaneously.
When battery powered, the user can expect reliable measurement over a long period of time. The
E112-P has several smart power management functions to extend the (optional) battery life time
significantly next to permanently disabling the infra-red keys. The following functions can be set:
LCD NEW
3.2 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.
The following refresh rates can be selected:
fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
(read 3 sec as a refreshment every 3 seconds, 30 sec as a refreshment
every 30 seconds)
When “off” is selected the display will be automatically switched off after
30 seconds since the last action. The display will return again after
touching one of the keys.
BACKLIGHT
3.3 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 untis the brightness will not change.
Note: When the unit is only loop powered it cannot make use of the
backlight. In that case an external supply is required.
BARGRAPH
3.4 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
RATESPAN
3.5 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:
0000.000 - 9999999
The number of decimals displayed depends upon SETUP 2.3.

5 - LINEARIZE
The linearization function is available to approach the real flow curve better as with the general
K-factor (KF0) entered with setup 1.4 and 2.4. 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
5.1 TO 5.F
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 5.H - 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.
DISABLE / ENABLE

6 - ANALOG OUTPUT
An analog 4-20mA signal is generated according to the flowrate with a 12 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:
OUTPUT
6.1 The analog output can be disabled.
In case of a passive analog output 3.5mA will be generated if a power
supply is available but the output is disabled. The following can be
selected:
enable – disable
RATE MIN
6.2 Enter here the flowrate at which the output should generate the minimum
signal (4mA) - in most applications at flowrate "zero".
The number of decimals displayed depends upon SETUP 2.3.
The time and measuring units (L/min for example) depend upon SETUP
2.1 and 2.2 and are displayed during editing.
RATE MAX
6.3 Enter here the flowrate at which the output should generate the maximum
signal (20mA) - in most applications at maximum flow.
The number of decimals displayed depends upon SETUP 2.3.
The time and measuring units (L/min for example) depend upon SETUP
2.1 and 2.2 but cannot be displayed.
CUT-OFF
6.4 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).
When the flow is less than the required rate, the current will be the
minimum signal (4mA).
Examples:
4MA
(SETUP 6.2)
20MA
(SETUP 6.3)
CUT-OFF
(SETUP 6.4)
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
6.5 The initial minimum analog output value is 4mA. However, this value
might differ slightly due to external influences such as temperature for
example. The 4mA 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. 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 and 4mA at maximum flowrate for
example!
TUNE MAX / 20MA
6.6 The initial maximum analog output value is 20mA. However, this value
might differ slightly due to external influences such as temperature for
example. The 20mA 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 20mA. 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 4mA at maximum flowrate and 20mA at minimum flowrate for
example!
