Proline Promag 51 Safety instructions
Endress+Hauser 5
1 Safety instructions
1.1 Designated use
The Promag 51 measuring device described in these Operating Instructions is approved to
OIML R49 and has an EC type-examination certificate according to Measuring Instruments
Directive 2004/22/EC (MID) for use in legal metrological control ("custody transfer") for cold
water (MI-001).
A minimum conductivity of 20 μS/cm is required for measuring demineralized water. Fresh water
can be measured as of a minimum conductivity of 5 μS/cm.
The Promag 51 is operated with a totalizer display for legal metrological control and, optionally,
with a pulse output for legal metrological control.
The measuring system operates within a temperature range of 0 to +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 Promag 51 measuring system for legal metrological control is protected by seals on the
transmitter or the sensor connection housing from manipulation of parameters relevant to
measuring technology (see Page 72). 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
facility's owner-operator according to the Measuring Instruments Directive 2004/22/EC (MID).
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 is willing to assist in clarifying the chemical resistance properties of parts wetted
by special fluids, including fluids used for cleaning. However, small changes in temperature,
concentration or the degree of contamination in the process can result in changes of the chemical
resistance properties. Therefore, Endress+Hauser can not guarantee or accept liability for the
chemical resistance properties of the fluid wetted materials in a specific application.
The user is responsible for the choice of fluid wetted materials in regards to their in-process
resistance to corrosion.
• If welding work is performed on the piping system, do not ground the welding appliance through
the 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.

Safety instructions Proline Promag 51
6Endress+Hauser
1.3 Operational safety
Note the following points:
• Measuring systems for use in hazardous environments are accompanied by separate
Ex documentation, 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
inspection authority (e.g. 0Europe, 2USA, 1Canada).
• The measuring device complies with the general safety requirements in accordance with
EN 61010-1, the EMC requirements of IEC/EN 61326, and NAMUR recommendation NE 21
and NE 43.
• Due to the performance rate in the electronic components, the maximum heating of the outer
housing surfaces is 10 K. When hot fluids are passed through the measuring tube, the surface
temperature of the housing increases. With regard to the sensor, in particular, you should expect
temperatures that can be close to the fluid temperature.
If the temperature of the fluid is high, ensure staff are protected against burns and scalds.
• 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
• 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.
• Please note the measures on ä79

3.1 Incoming acceptance, transport and storage
3.1.1 Incoming acceptance
On receipt of the goods, check the following points:
• Check the packaging and the contents for damage.
• Check the shipment, make sure nothing is missing and that the scope of supply matches your
order.
3.1.2 Transport
The following instructions apply to unpacking and to transporting the device to its final location:
• Transport the devices in the containers in which they are delivered.
• 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.
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.
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
transmitter and the appropriate measuring sensors. ä84
• 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.
• 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.

3.2 Installation conditions
3.2.1 Dimensions
The dimensions and lengths of the sensor and transmitter are provided in the "Technical
Information" document for the device in question. This can be downloaded as a PDF file from
www.endress.com. A list of the "Technical Information" documents available is provided in the
"Documentation" section on ä91.
3.2.2 Mounting location
Entrained air or gas bubbles in the measuring tube can result in an increase in measuring errors.
Avoid the following locations:
• Highest point of a pipeline. Risk of air accumulating
• Directly upstream a free pipe outlet in a vertical pipeline.
A0008154
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 ä85.
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 ä84.

Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration.
The Empty Pipe Detection function (EPD ä59) 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.
A0008155
Fig. 9: Installation in partially filled pipe
Down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes whose length h is 5 m
(16.4 ft). This precaution is to avoid low pressure and the consequent risk of damage to the lining
of the measuring tube.
This measure also prevents the system losing prime, which could cause air inclusions. Information
on the lining's resistance to partial vacuum can be found on ä85.

3.2.3 Orientation
An optimum orientation helps avoid gas and air accumulations and deposits in the measuring tube.
However, Promag also offers the additional empty pipe detection function for detecting partially
filled measuring tubes, e.g. in the case of degassing fluids or varying process pressure:
• Electrode Cleaning function (ECC) to prevent electrically conductive buildup in the measuring
tube, e.g. in the case of fluids that cake ("Description of Device Functions" manual)
• Empty Pipe Detection (EPD) ensures the detection of partially filled measuring tubes,
e.g. in the case of degassing fluids or varying process pressure (ä59)
Vertical orientation
This is the ideal orientation for self-emptying piping systems and for use in conjunction with Empty
Pipe Detection.
A0008158
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 (å11). 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 × DN
•Outletrun:2 × DN
A0003210

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 ä84.

3.2.5 Foundations, supports
If the nominal diameter is DN 350, mount the transmitter on a foundation of adequate load-
bearing strength.
"Caution!
Risk of damage.
Do not support the weight of the sensor on the metal casing: the casing would buckle and damage
the internal magnetic coils.
A0003209
Fig. 15: Correct support for large nominal diameters (DN 350)
3.2.6 Adapters
Suitable adapters to DIN EN 545 (double-flange reducers) can be used to install the sensor in larger-
diameter pipes.
The resultant increase in the rate of flow improves measuring accuracy with very slow-moving
fluids. The nomogram shown here can be used to calculate the pressure loss caused by cross section
reduction.
!Note!
The nomogram applies to fluids of viscosity similar to water.
1. Calculate the ratio of the diameters d/D.
2. From the nomogram read off the pressure loss as a function of flow velocity (downstream
from the reduction) and the d/D ratio.

3.2.8 Length of connecting cable
In order to ensure measuring accuracy, comply with the following instructions when installing the
remote version:
• Secure the cable run or route the cable in a conduit. Movement of the cable can falsify the
measuring signal, particularly if the fluid conductivity is low.
• Route the cable well clear of electrical machines and switching elements.
• If necessary, ensure potential equalization between sensor and transmitter.
• The permissible length of the connecting cable Lmax depends on the fluid conductivity
(å17). A minimum conductivity of 20 μS/cm is required for measuring demineralized
water. Most liquids can be measured as of a minimum conductivity of 5 μS/cm.
• The maximum length of the connecting cable is 10 m (32.8 ft) when Empty Pipe Detection
(EPD ä59) is switched on.
