1.3 Safety notes
DANGER
Only qualifi ed and trained personnel should
assemble, electrically connect and commission
the GEMÜ 3030 mFlow. Use qualifi ed
personnel for operation, servicing, inspection
and assembly. The areas of responsibility, the
monitoring of personnel and their competence
areas should be defi ned precisely by the

1.4 Correct use
7 The GEMÜ 3030 mFlow is suitable for use as defined in the
datasheet. In order to ensure correct product function, the
following notes should be observed. Pay attention to the
information on the product labels.
7 Non-observance of these notes and the notes in the general
operating instructions will void the guarantee on the GEMÜ
3030 mFlow and lead to a loss of legal liability.
7 The GEMÜ 3030 mFlow is used exclusively to measure flow
rates and flow velocities of liquid media and must be used
as specified in the datasheet.
7 Any other use or use above and beyond this is not
permitted. GEMÜ shall not be liable for any consequential
damage. The user carries sole risk.
7 Please pay attention to the pertinent technical safety
regulations when planning both the use and operation of the
device. The designer, plant constructor or operator is always
responsible for positioning and installing the GEMÜ 3030
mFlow.
1.5 Information on use in damp conditions
Under no circumstances whatsoever may the
GEMÜ 3030 mFlow be cleaned with a high
pressure cleaning device, because the protection
class IP 65 is not su cient for this.
The following information is intended to help when installing
and operating the GEMÜ 3030 mFlow in damp conditions:
Lay cables and pipework so that condensate or rain water
that remains on the pipework/cables cannot enter the cable
glands of the M12 plugs of the GEMÜ 3030 mFlow.
Check that all of cable glands for the M12 plug and the
fi ttings are mechanically secured.
1.6 Tools required for installation and assembly
The tools required for installation and assembly are not
included in the scope of delivery.
2 Manufacturer's information
2.1 Transport
G Only transport the flowmeter by suitable means. Do not drop
it and handle it with care.
G Dispose of packing material according to relevant local or
national disposal regulations / environmental protection
laws.
2.2 Delivery and performance
G Check that all parts are present and check for any damage
immediately upon receipt.
G The scope of delivery is apparent from the dispatch
documents and the design from the order number.
G The flowmeter's performance is tested at the factory.
2.3 Storage
G Store the flowmeter free from dust and moisture in its
original packaging.
G Avoid UV rays and direct sunlight.
G Maximum storage temperature: 60 °C.
2.4 Function
The magnetically inductive fl owmeter GEMÜ 3030 mFlow is
suitable for electrically conductive media (conductivity 20 S/
cm) and enables precise measurement of fl ow velocities and
volumetric fl ows of inert and corrosive liquids.
The fl owmeter works largely independently of the pressure,
temperature, density and viscosity of the medium.
The GEMÜ 3030 mFlow has two relay outputs, an RS-232
interface and a pulse and internally supplied current output
(4-20 mA).
As an option, the fl owmeter comes with an infrared interface
and/or a Profi bus DP interface, which can be used to operate
the GEMÜ 3030 mFlow.
The information required can be called-up on the two-line
display of the GEMÜ 3030 mFlow. Self-explanatory help texts
that explain the meaning of the parameters called-up are also
displayed.
The GEMÜ 3030 mFlow is operated using four keys.
2.5 GEMÜ CONEXO
The interaction between valve components equipped with
RFID chips and the corresponding IT infrastructure actively
increases process reliability.
Thanks to serialization, every valve and every relevant valve
component such as the body, actuator or diaphragm, and
even automation components, can be clearly traced and read
using the CONEXO pen RFID reader. The CONEXO app,
which can be installed on mobile devices, not only facilitates
and improves the „installation qualifi cation“ process, but also
makes the servicing process much more transparent and
easier to document. The app actively guides the maintenance
technician through the maintenance schedule and directly
provides him with all the information assigned to the valve,
such as test reports, testing documentation and maintenance
histories. The CONEXO portal acts as a central element,
helping to collect, manage and process all data.

4 Assembly / disassembly
4.1 Assembly
Before installing the GEMÜ 3030 mFlow in the piping, drain
and cool the piping to avoid caustic burns from the medium
and scalding.
The sensor should preferably be installed in a vertical rising
pipeline with an upwards flow direction. Installation in penstock
should be avoided wherever possible. Ensure that piping is
continuously filled.
Flow
In horizontal lines, care should be taken to avoid trapped air
when installing the sensor, as otherwise the measurement
result will be falsified.
Correct
Trapped air
Incorrect
Trapped air
There must be no free outlet downstream of the GEMÜ 3030
mFlow to ensure that the piping is always completely filled.
Correct
Flow
Incorrect
Flow
In addition, the flowmeter should be attached in the horizontal
installation position to the side of the lower specified area.
Preferred installation position
Installation position not recommended
Risk of trapped air
Risk of solid deposits
In order to avoid flow turbulence due to bends in lines that may
falsify the measurement result, a straight inlet distance of 10 x
DN and a straight outlet distance of 5 x DN should be provided.
Flow
The electronics housing with display can be rotated through
370°.

For plant-specific reasons, potential differences may occur
between the piping and reference earth.
To eliminate this, do the following:
Earth the piping upstream and downstream of the fl owmeter.
Connect pin 3 of plug X3 to the same potential.
To ensure accuracy, the sensor must already have
been in the medium to be measured for 24 hrs (with
supply voltage applied).

In certain areas, various codes are used to protect the confi guration level on the GEMÜ 3030 mFlow against improper changing of
parameters.
All menu items are marked by symbols indicating their write and read protection.

Example:
Default No
Yes...No

The following symbols are used for this purpose:
r0: no release required for reading
w0: no release required for writing
r1: lowest priority release code 1 required for reading
w1: lowest priority release code 1 required for writing
r2: medium priority release code 2 required for reading
w2: medium priority release code 2 required for writing
r3: top priority release code 3 required for reading
w3: top priority release code 3 required for writing
The codes can be changed or activated in the following menu:

Code:
Enter code for user access. The currently released user level is displayed at Active Level.
Example:
In Active Level 0, the fl owmeter is disabled in all three user levels.
Only the parameters marked by the symbol r0w0 can be read and changed.
Logout:
Serves to log out of write protected and read protected areas in the menu. This function disables various menus depending on the
user level activated.
User level 0 is displayed in parameter Active Level.
NewCode1:
Enter the new code for the lowest user level (user level 1) (factory setting 0).
NewCode2:
Enter the new code for the medium user level (user level 2) (factory setting 0).
NewCode3:
Enter the new code for the top user level (user level 3) (factory setting 0).
Factory setting 0 means that all three codes are assigned 0. This means that all parameter menus are released.
Example:
If user level 2 is to be disabled, user level 2 and also user level 3 must be assigned a code.
During activation or deactivation of the user levels via the RS232 interface, other codes can be assigned in the same
way as the direct input of codes via the GEMÜ 3030 mFlow keypad.
This ensures specifi c disabling of the use of the fl owmeter either directly via the fl owmeter or via the RS232 interface,
depending on the type of operation.
The codes for operation via the RS232-interface can only be assigned, activated or deactivated via the RS232-interface. The
codes for direct operation via the GEMÜ 3030 mFlow keypad can only be assigned, activated or deactivated via the keypad on the
unit itself.
