1Basic information
1.1 Basic features
The inductive flow meter F5 is designed to measure, indicate and record the instantaneous and total flow of
the conductive media flowing through the sensor. The flow meter F5 records both forward and reverse flows.
As there are no moving parts in the flow profile the F5 can be used to measure extremely dirty liquids
containing solids. The only limitation is that the flowmeter can be used solely with conductive liquids.
Range of applications. The inductive flow meter F5 is for use in the Chemical Industry, Paper Industry,
Water and Wastewater Treatment Industry and most other process industries.
Features. The inductive flowmeter F5 is a highly accurate and stable device. The construction of the F5
flowmeter uses components with long-term, time and temperature stability. Configuration data is backed up
and can be recovered after a power failure. The back-up structure enables data recovery even if a partial loss
of data occurs as a result of (e.g. high level electrostatic discharge or a noisy power supply). Internal CPU
provides all functions usually built in electronic flow meters, incl. low flow rate correction, frequency
response setting, bandwidth of sensitivity setting at low flow rates, etc.
Power supply. F5 is supplied from internal lithium battery and doesn't need external power supply.
1.2 Warranty
Within the manufacturers general supply conditions, all material and manufacturing faults are covered by
warranty. Upon warranty claim, Emkometer will test the item and decide whether to repair it or replace with
a new one. Place of the warranty obligation is Czech Republic. Further claims on compensation, especially
for loss of production or resultant of damages, are strictly excluded.

Battery operated magnetic flowmeter F5 EMKOMETER
4 Operation manual
Any defects caused by improper use are absolutely not included in the warranty. Excluded from warranty
are also expendable items (as i.e. accumulators, batteries, pushbuttons after attained life time, ribbons, etc.)
In case of a warranty claim the user is asked to give detailed description of the defect and also of the
application for which you use the product. This information is important in order to avoid time and cost
extensive tests and for the eventual achievement of warranty claims from our suppliers and sub-suppliers.
For the item or instrument, returned after the expired warranty time, repair or replacement on warranty can
only be accepted, if manufacturer has been informed in time that a warranty case has occurred.
Warranty period for all types of electromagnetic flowmeter is 24 months.
The flowmeter should only be used according to the
instructions described in this operating manual.
2Preparing for start up
2.1 Inspecting contents of the package
Basic package includes the following items:
•Flanged sensor
•Electronic Transmitter (can be integral or remote) Operating manual.
The flowmeter is delivered ready for use after connecting to the power supply. Please check that it has been
correctly installed according to chapter “Installation”.
3Installation
3.1 Sensor location
Observe the following instructions to avoid measurement errors due to air bubbles or partially filled pipe:
Horizontal (standard) mounting
The sensor tube must always remain full. The best way to achieve this is to locate the sensor in a low section
of pipe, see the following picture. It is recommended to install the sensor in a section of straight pipe with at
least 5 times the pipe diameter before sensor and 3 times after sensor.

EMKOMETER Battery operated magnetic flowmeter F5
Operation manual 5
Pipe reducers
If the pipe diameter is not the same as the diameter of sensor, then pipe reducers can be used. So as not to
lose accuracy of the measurement, the slope of reducers should not exceed 8 .
Vertical mounting
When the sensor is mounted on a vertical section of pipe, the flow direction must be upwards. In the case of
a downward flow direction, air bubbles could collect in the sensor resulting in unstable and inaccurate
measurement.

Pumps
Never install the sensor on the suction side of a pump or on a section of pipe where a vacuum is possible.
Valves
Suitable location of a shutoff valve is downstream of a sensor.
Removal during maintenance
If the application requires removal of the sensor for periodic maintenance, it is recommended to install a
bypass section as the following drawing.

EMKOMETER Battery operated magnetic flowmeter F5
Operation manual 7
Position of electrodes
The axis of measuring electrodes must be approximately horizontal (see picture).
YES NO
Vibration
To avoid mechanical damage protect
both electronic unit and sensor against
mechanical vibrations. When strong vibrations are possible, both the input and
output pipe must be mechanically fixed or the remote version with a separate electronic unit should be
used.
Overheating
To avoid overheating, the electronic unit should be protected against direct sunlight especially in areas with
a warm climate with ambient temperatures over over 30 °C. If necessary a sunshade has to be mounted
over the electronic unit or a remote version with a separate electronic unit should be used.
3.2 Battery connection
The flowmeter is delivered with disconnected internal battery. Use the following procedure to connect
battery after installation of the flowmeter.
•Unscrew the back cover using the screwdriver.
•Insert the battery
•Screw the back cover on again.
3.3 Battery replacement
The battery life time depends on excitation frequency, flowmeter settings and ambient temperature.
These actions decrease battery lifetime the most:
•Short excitation time
•USB connection
•Active display
If the battery indicates low state, remove the battery by the following steps:

Battery operated magnetic flowmeter F5 EMKOMETER
8 Operation manual
1) Activate MENU → SETUP → GENERAL → BATTERY → Change new (yes)
You will be prompted to insert a new battery.
2) Insert new battery
3) Check date and time
3.4 Electric connection between converter and sensor –Remote version
For remote version converter and flanged sensor are connected with two (2-wire unshielded and 3-wire
shielded) cables. Standard length of cables is 6 meter. It is recommended to mount the transmitter not too
far from the flanged sensor. Use cables as short as possible.
Five-terminal connector is located in separated box. The same box is used for the converter and also for the
sensor. Colours of wires are following:
3-wire shielded cable (shielding is connected to the green wire):
Blue (Brown) : Electrode 1 (EL1)
Green : Ground
Red (White): Electrode 2 (EL2)
2-wire cable:
Brown : Excitation 1 (EXCITATION)
White : Excitation 2 (EXCITATION)
Use the following procedure to connect sensor cable to the transmitter or sensor:
•Switch off power supply.
•Dismount top cover of connection box. Four screws must be removed.
•Connect 5 wires to the connector.
•As the basic protection of connection box is IP65 it is important (in case you need better protection) to
fill the box (with connected wires) with reenterable insulating and sealing compound. One piece of
compound is standard part of delivery. Using this technology will be protection of transmitter IP67 and
protection of sensor IP68.
•Mount the cover back.
•Switch on power supply.
3.5 Sensor grounding
Proper grounding is critical for correct flow meter operation. The sensor is equipped with screw connection
for a grounding wire. This screw has to be connected to both pipeline flanges. Use Copper wire to connect
between the flange and the grounding screw on the sensor.
If the pipeline is made of an electricallynonconductive material, or if the pipe is lined with a similar material,
special grounding rings must be installed between flanges.
Note: Do not switch the flow meter on if it’s not properly grounded!

6System control
Flowmeter can be connected to the computer via USB bus. USB connector is located behind the front panel.
In fact, the connected computer creates a virtual serial port RS232 and utilities communicate with the layer
RS232. Communication parameters must be set in menu (item USB-RS232).
USB interface can work in three modes:
a) Normal –communication protocol ADAM compatible with flowmeter M910 and M920.
b) Modbus RTU –communication protocol Modbus, binary communication.
c) Modbus ASCII –communication protocol Modbus, ASCII communication.
To transfer data in Normal mode 8N1 data format is used, i.e. each data word includes 8 bits, no parity and
one stop bit. The communication speed can be set using the system menu. Available values: 1200, 2400,
4800, 9600 and 19200 Bd. Flowmeter in Modbus mode has its own modbus address. Range of this address
is from 1 to 247.
6.1 Command syntax
Communication between flowmeter and computer consists of a flow of periodically alternating commands
type command-response or query-response. Command is always a text followed by parameter and ended by
control sign <cr>. Response is always ended with control sign <cr>.
There are three types of responses:
1) Parameters value –response to a query
2) Ok –response to a command
3) ErrX –in case that command has wrong format. Where X is error code from the table below:
Error code
Meaning

Syntax description
<DNPD> = Decimal Numeric Program Data, this format is used to express decimal number with or without
the exponent.
<CPD> = Character Program Data. Usually, it represents a group of alternative character parameters. e.g. {0
| 1 | 2 | 3}.
? =
A flag indicating a request for the value of the parameter specified by the command. No other
parameter than the question mark can be used.
(?) =
A flag indicating a request for the parameter specified by the command. This command permits
a value to be set as well as requested.
<cr> =
carriage return. ASCII code 13. This code executes the command or query.
6.2 Command list
6.2.1 Main menu
Flowrate reading
RFL?
Response contains actual “Flowrate” value in selected units.
Example:
If query „RFL?<cr>” is sent, flowmeter returns response in format „100.000<cr>“. Resolution is designed
by Setup menu.
Volume reading
RVO?
Response contains actual “Volume” counter value in selected units.
Example:
If query „RVO?<cr>” is sent, flowmeter returns response in format „100.000<cr>“. Resolution is designed
by Setup menu.
Positive volume reading
RVP?
Response contains actual Positive volume counter value.
Example:
If query „RVP?<cr>” is sent, flowmeter returns response in format „100.000<cr>“. Resolution is designed
by Setup menu.
Negative volume reading
RVN?
Response contains actual Negative volume counter value.

6.2.2 Flowmeter
6.2.2.1 Flowrate parameters
Flowrate unit
FFS(?) <CPD> { 0 | 1 | 2 | 3 | 4 }
Following units can be set:
•0 l/s
•1 m3/h
•2 UG/m
•3 IG/m
•4 “User”
F5 confirms execution with string „Ok<cr>”.
Example:
Command „FFS 0<cr>” sets flowrate unit “l/s”. If query „FFS?<cr>” is sent, flowmeter returns response in
format „0<cr>”.
Flowrate user unit
FFU(?) <CPD>
Command sets text for flowrate user unit.
<CPD>
It represents user units expressed as 5 ASCII characters. F5 confirms execution with string „Ok<cr>”. In
case of query F5 returns set user unit.
Example:
Command „FFU l/m <cr>” sets flowrate user unit “ l/m “. After query „FFU?<cr>” flowmeter returns string
„l/m <cr>”.
Conversion constant for flowrate user unit
FFC(?) <DNPD>
Command sets conversion constant for flowrate user unit with respect to [l/s].
<DNPD>
It represents a constant, which is calculated as a ratio between flowrate in user unit and flowrate in basic unit
( [l/s] ). For example constant for [m3/h] is 3.6. F5 confirms execution with string „Ok<cr>”. In case of
query F5 returns set constant.
