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.

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.

6 Operation manual

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:

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!
