Commissioning with “QUICK SETUP” Page 76 ff.
You can commission the measuring device quickly and easily, using the special
“Quick Setup” menu. It enables to configure important basic functions using the local
display, for example display language, measured variables, units engineering, type of signal,
etc.
The following adjustments can be made separately as necessary:
– Empty-pipe/full-pipe adjustment for empty pipe detection (EPD)
– Configuration of current output (active/passive)
▼
Customer-specific configuration Page 54 ff.
Complex measuring operations necessitate additional functions that you can configure as
necessary with the aid of the function matrix, and customize to suit the process parameters.
All functions are described in detail, as is the function matrix itself, in the “Description of
Device Functions” manual, which is a separate part of this Operating Instruction.

Proline Promag 51 1 Safety instructions
Endress+Hauser 7
1 Safety instructions
1.1 Designated use
The measuring system Promag 51 is PTB certified for custody transfer with cold water and may be
used for measuring the flow of freshwater having a minimum conductivity of 5 µS/cm. A minimum
conductivity of 20 µS/cm is required for measuring demineralized water.
The Promag 51 is operated with a totalizer display suitable for custody transfer and, optionally, with
a pulse output suitable for custody transfer. The measuring system operates within a temperature
range of 0...+30 °C and can be deployed, for example, in the supply of drinking water:
• Internal monitoring of delivery pipe network (local water network)
• Calculation of the bill from the main supply pipe (junctions)
• Monitoring of the water source. For example, the amount of ground water (tank inlet points,
incl. pump stations).
• Certification for the amount supplied to the delivery network (tank outlet points).
• Monitoring of the withdrawal and supply of different water works in a supply pipe (overland
supply pipe of a water network).
Resulting from incorrect use or from use other than that designated the operational safety of the
measuring devices can be suspended. The manufacturer accepts no liability for damages being
produced from this.
1.2 Installation, commissioning and operation
Note the following points:
• A calibrated Promag 51 measuring system is protected by seals on the transmitter or the sensor
connection housing from manipulation of calibration parameters. As a rule, these seals may only
be broken by a representative of the appropriate approval authorities.
• Installation, connection to the electricity supply, commissioning and maintenance of the device
must be carried out by trained, qualified specialists authorized to perform such work by the facil-
ity's owner-operator. The specialist must have read and understood these Operating Instructions
and must follow the instructions it contains.
• The device must be operated by persons authorized and trained by the facility's owner-operator.
Strict compliance with the instructions in the Operating Manual is mandatory.
• Endress+Hauser will be happy to assist in clarifying the chemical resistance properties of parts
wetted by special fluids, including fluids used for cleaning.
• If welding work is performed on the piping system, do not ground the welding appliance through
the Promag flowmeter.
• The installer must ensure that the measuring system is correctly wired in accordance with the
wiring diagrams. The transmitter must be grounded, unless special protective measures have been
taken (e.g. galvanically isolated power supply SELV or PELV).
• Invariably, local regulations governing the opening and repair of electrical devices apply.

1.3 Operational safety
Note the following points:
• Measuring systems for use in hazardous environments are accompanied by separate Ex documen-
tation, which is an integral part of these Operating Instructions. Strict compliance with the
installation instructions and ratings as stated in this supplementary documentation is mandatory.
The symbol on the front of this documentation indicates the approval and the certification body
(0Europe, 2USA, 1Canada).
• The measuring device complies with the general safety requirements in accordance with
EN 61010, the EMC requirements of EN 61326/A1, and NAMUR recommendation NE 21.
• The manufacturer reserves the right to modify technical data without prior notice. Your
Endress+Hauser distributor will supply you with current information and updates to these
Operating Instructions.
1.4 Return
The following procedures must be carried out before a flowmeter requiring repair or calibration,
for example, is returned to Endress+Hauser:
• Always enclose a duly completed “Declaration of contamination” form. Only then can
Endress+Hauser transport, examine and repair a returned device.
• Enclose special handling instructions if necessary, for example a safety data sheet as per
EN 91/155/EEC.
• Remove all residues. Pay special attention to the grooves for seals and crevices which could
contain residues. This is particularly important if the substance is hazardous to health, e.g.
flammable, toxic, caustic, carcinogenic, etc.
!Note!
You will find a preprinted “Declaration of contamination” form at the back of this manual.
#Warning!
• Do not return a measuring device if you are not absolutely certain that all traces of hazardous
substances have been removed, e.g. substances which have penetrated crevices or diffused
through plastic.
• Costs incurred for waste disposal and injury (burns, etc.) due to inadequate cleaning will be
charged to the owner-operator.

• Transport the devices in the containers in which they are delivered.
• Do not remove the protective plates or caps on the process connections until the device is ready
to install. This is particularly important in the case of sensors with PTFE linings.
Special notes on flanged devices
"Caution!
• The wooden covers mounted on the flanges before the device leaves the factory protect the linings
on the flanges during storage and transportation. Do not remove these covers until immediately
before the device is installed in the pipe.
• Do not lift flanged devices by the transmitter housing, or the connection housing in the case of
the remote version.
Transporting flanged devices (DN ≤300):
Use webbing slings slung round the two process connections (Fig. 5). Do not use chains, as they
could damage the housing.
#Warning!
Risk of injury if the measuring device slips. The center of gravity of the assembled measuring device
might be higher than the points around which the slings are slung.
At all times, therefore, make sure that the device does not unexpectedly turn around its axis or slip.

Transporting flanged devices (DN ≥ 350):
Use only the metal eyes on the flanges for transporting the device, lifting it and positioning the
sensor in the piping.
"Caution!
Do not attempt to lift the sensor with the tines of a fork-lift truck beneath the metal casing. This
would buckle the casing and damage the internal magnetic coils.

3.1.3 Storage
Note the following points:
• Pack the measuring device in such a way as to protect it reliably against impact for storage
(and transportation). The original packaging provides optimum protection.
• The storage temperature corresponds to the operating temperature range of the measuring trans-
mitter and the appropriate measuring sensors.
• The measuring device must be protected against direct sunlight during storage in order to avoid
unacceptably high surface temperatures.
• Choose a storage location where moisture does not collect in the measuring device. This will help
prevent fungus and bacteria infestation which can damage the liner.
• Do not remove the protective plates or caps on the process connections until you are ready to
install the device. This is particularly important in the case of sensors with PTFE linings.

3.2 Installation conditions
3.2.1 Dimensions
All the dimensions and lengths of the sensor and transmitter are provided in the separate
documentation “Technical Information”.
3.2.2 Mounting location
Correct measuring is possible only if the pipe is full. Avoid the following locations:
• Highest point of a pipeline. Risk of air accumulating
• Directly upstream a free pipe outlet in a vertical pipeline.

Fig. 7: Location
Installation of pumps
Do not install the sensor on the intake side of a pump. This precaution is to avoid low pressure
and the consequent risk of damage to the lining of the measuring tube. Information on the lining's
resistance to partial vacuum can be found on → Page 111.
It might be necessary to install pulse dampers in systems incorporating reciprocating, diaphragm
or peristaltic pumps. Information on the measuring system's resistance to vibration and shock
can be found on → Page 109.

Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration. The Empty Pipe Detection
function (see Page 77) offers additional protection by detecting empty or partially filled pipes.
"Caution!
Risk of solids accumulating. Do not install the sensor at the lowest point in the drain. It is advisable
to install a cleaning valve.

Fig. 9: Installation in partially filled pipe
Down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes longer than 5 meters. This
precaution is to avoid low pressure and the consequent risk of damage to the lining of the measuring
tube. These measures also prevent the system losing prime, which could cause air inclusions.
Information on the lining's resistance to partial vacuum can be found on Page 111.

3.2.3 Orientation
An optimum orientation helps avoid gas and air accumulations and deposits in the measuring tube.
Promag, nevertheless, supplies a range of functions and accessories for correct measuring of prob-
lematic fluids:
• Empty Pipe Detection (EPD) ensures the detection of partially filled measuring tubes,
e.g. in the case of degassing fluids or varying process pressure (see Page 77)
• Exchangeable Measuring Electrodes for abrasive fluids (see Page 100)
Vertical orientation
This is the ideal orientation for self-emptying piping systems and for use in conjunction with Empty
Pipe Detection.
F06-5xxxxxxx-11-00-00-xx-004
Fig. 11: Vertical orientation
Horizontal orientation
The measuring electrode plane should be horizontal. This prevents brief insulation of the two
electrodes by entrained air bubbles.
"Caution!
Empty Pipe Detection functions correctly only when the measuring device is installed horizontally
and the transmitter housing is facing upward (Fig. 12). Otherwise there is no guarantee that Empty
Pipe Detection will respond if the measuring tube is only partially filled or empty.

Inlet and outlet runs
If possible, install the sensor well clear of fittings such as valves, T-pieces, elbows, etc. Compliance
with the following requirements for the inlet and outlet runs is necessary in order to ensure
measuring accuracy.
• Inlet run ≥ 5 x DN
•Outletrun≥2 x DN
"Caution!
• The inlet run and the outlet run must have the same nominal width as the flowmeter!
• This data is applicable even with the use of adapters to increase fluid velocity (see Page 22).

3.2.4 Vibrations
Secure the piping and the sensor if vibration is severe.
"Caution!
It is advisable to install sensor and transmitter separately if vibration is excessively severe.
Information on resistance to vibration and shock can be found on →Page 109.
