1. INTRODUCTION

1.1. SYSTEM DESCRIPTION

Functions and features

The flow rate monitor / totalizer, model F118-P is a microprocessor driven instrument designed to

linearize the flowmeters flow curve and to show the flow rate, the total and the accumulated total.

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.

One flowmeter with a passive or active pulse, Namur or sine wave (coil) signal output can be

connected to the F118-P. To power the sensor, several options are available.

Standard outputs

▪Max. three configurable alarm / pulse outputs: flow rate alarm, high- or low-flow rate alarm. Switched

as long as the flow rate is too high or too low.

▪Pulse output to transmit a pulse that represents a linearized totalized quantity as programmed.

▪Linear (0)4-20mA or 0-10V analog output to represent the actual, linearized, flow rate as

programmed. The (0)4-20mA or 0-10V signal limits can be tuned.

Fig. 1: typical application

Configuration of the unit

The F118-P is designed for use in many types of applications. For that reason, a setup menu is

available to program the F118-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. 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.

•Take careful notice of the "Safety rules, instructions and precautionary measures" in the

front of this manual.

This chapter describes the daily use of the F118-P. This instruction is meant for users / operators.

2.1. CONTROL PANEL

The control panel has three keys. The available keys are:

Fig. 2: Control Panel

Functions of the keys

This key is used to program and save new values or settings.

The PROG/ENTER key is also used to gain access to the setup menu (read

chapter 3).

This key is used to select the accumulated total.

The SELECT/key is also used to increase a value after the PROG/ENTER key has

been pressed (read chapter 3).

This key is used to reset the total.

The CLEAR/key is also used to select a digit or an option after the PROG/ENTER

key has been pressed read chapter 3).

2.3. OPERATOR INFORMATION AND FUNCTIONS

In general, the F118-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 F118-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 flow rate / total or flow rate

This is the main display information of the F118-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 displayed. The arrows 

indicate the increase/decrease of the flow rate trend.

▪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.

3.1.2. EXPLANATION OF SETUP MENU 1 - TOTAL

UNIT

This setting is used to select the engineering unit for the indication of the total, the

accumulated total 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

This setting is used to set the amount of digits behind the decimal point for the

(accumulated) total indication.

K-FACTOR

This setting is used to set the K-Factor for the total. 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

(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

This setting is used to set the amount of digits behind the decimal point for the

K-Factor.

3.1.3. EXPLANATION OF SETUP 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.

UNIT

This setting is used to select the engineering unit for the indication of the flow rate.

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

This setting is used to set the time unit for the flow rate calculation. Note that the

flow rate is given in engineering unit/time unit, e.g. liters/minute (l/min).

DECIMALS

When you change this setting, also recalculate and change the settings

for the analog rate-min and analog rate-max.

K-FACTOR

This setting is used to set the amount of digits behind the decimal point for the

flow rate indication.

DECIMALS K-FACTOR

This setting is used to set the K-Factor for the flow rate. 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.

FW_F118P_v1901_02_EN.docx

Page 12

CALCULATION

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.

CUT-OFF

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.

These settings determine how the flow rate is monitored and how the F118-P will process the alarm

conditions. For the setup of the configurable outputs, refer to setup menu: Relays.

FLOWZERO

When the flow rate is zero, then it is possible to ignore or disable the flow rate

monitoring. The following settings can be selected:

DEFAULT: in case of a low-flow rate alarm and zero flow, it will switch the

alarm output and indicate the alarm on the display.

NO RELAY: in case of a low-flow rate alarm and zero flow, it won't switch the

alarm output but will indicate the alarm on the display only.

IGNORE: in case of a low-flow rate alarm and zero flow, it won't switch the

alarm output and nothing will be indicated on the display.

ALARM LO

This submenu is used to activate the related alarm condition and to set the

threshold value for a this flow alarm. The setting 0.0 disables this alarm.

ALARM HI

This setting is used to activate the related alarm condition and to set the

threshold value for a this flow alarm. The setting 0.0 disables this alarm.

DELAY LO

This setting is used to set a delay time for the related alarm. When the

alarm condition is still valid after the delay time, an alarm is given.

DELAY HI

This setting is used to set a delay time for the related alarm. When the

alarm condition is still valid after the delay time, an alarm is given.

3.1.5. EXPLANATION OF SETUP MENU 4 - DISPLAY

FUNCTION

This setting can be set to display 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 measuring unit. When SELECT is pressed, the

total and the accumulated total are shown temporarily.

ALARM SET

This setting is used to determine in which menu you can change the

alarm settings. When programmed for setup menu only, the alarm

settings in the operator menu are read-only.

LIGHT

The backlight brightness can be adjusted from 0% (off) to 100% (full

brightness) in steps of 20%.

When the F118-P is only loop powered, the backlight is disabled. An

external power supply is required to supply the backlight.

3.1.6. EXPLANATION OF SETUP MENU 5 - 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 F118-P has several smart power management functions to extend

the battery life time significantly. Two of these functions can be set.

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 sec. 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

The F118-P has two modes: operational or shelf.

After "shelf" has been selected, the F118-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 F118-p again, press the select/key two times.

3.1.7. EXPLANATION OF SETUP MENU 6 - FLOWMETER

SIGNAL

With this setting the type of flowmeter output is selected. The settings with

LP (low-pass) filter are used to apply a build-in noise reduction.

Selections "active pulse" offer a detection level of 50% of the supply

voltage.

3.1.7. EXPLANATION OF SETUP MENU 7 - LINEARIZE

The linearization function is available to approach the real flow curve better as with the general

K-Factor (KF0). This to obtain a more accurate flow rate, 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 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 calculation and the method of linearization:

FW_F118P_v1901_02_EN.docx

The frequency is shown at the bottom line of the display. The maximum

frequency is 9999.9 Hz. With value 0.0Hz, the M-Factor is disabled. The M-

Factor (MF) is shown at the top-line of the display. The minimum value to be

entered is 0.000001 and the maximum value is 9.999999.

The MF is mostly a figure around 1.000000, like 0.945354 or 1.132573 and

always has six decimals, but the decimal separator is not shown.

LINEARIZE

This setting is used to enable or disable the linearization function.

DECIMALS

FREQUENCY

This setting is used to set the amount of digits behind the decimal point for the

frequency.

3.1.8. 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 flowrate. 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

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

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

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.

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.

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_F118P_v1901_02_EN.docx

Page 15

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.

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 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

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.

3.1.9. EXPLANATION OF SETUP MENU 9 - RELAYS

The outputs are configurable, they can be set to a specific alarm output, a scaled pulse output

according accumulated total or to off (energy saving when not used).

There are three outputs in the submenu, but the amount of outputs can vary due to

regulations or chosen options.

RELAY 1

This setting is used to set the function of related output R1.

Mind that when set to pulse, the output has a maximum frequency of 5Hz

to prevent contact bounce.

For intrinsic safe applications (XI):

The setting in this submenu is overridden by the setting of relay 3.

RELAY 2

This setting is used to set the function of related output R2.

Mind that this output has a maximum frequency of 500Hz.

RELAY 3

This submenu is used to set the function of related output R3.

Mind that this output has a maximum frequency of 500Hz.

For intrinsic safe applications (XI): The setting of this output (fast output)

is assigned to R1 (option XI has only two outputs).

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!

DECIMALS

This setting is used to set the amount of digits behind the decimal point for the

amount.

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.
