1 Safety instructions
1.1 Designated use
The measuring device described in this Operating Manual is to be used only for measuring
the flow rate of conductive fluids in closed pipes.
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.
Examples:
• Acids, alkalis
• Drinking water, wastewater, sewage sludge
• Milk, beer, wine, mineral water, etc.
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:
• 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. The specialist must have read and understood this
Operating Manual 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 carrying out welding work on the piping, the welding unit must not be grounded by
means of the measuring device.
• The installer must ensure that the measuring system is correctly wired in accordance with
the wiring diagrams. The transmitter must be grounded, except in cases where special
protective
measures have been taken (e.g. galvanically isolated power supply SELV or PELV).

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 protection 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 protection
plates until immediately before the device is installed in the pipe.
• Do not lift flanged devices by the transmitter housing or, in the case of the remote version,
by the connection housing.
Transporting flanged devices DN
 300 (12")
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 300 (12")
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.
a0004295
Fig. 5: Transporting sensors with DN > 300 (12")
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 →160.
• 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 lining.
• Do not remove the protection 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
The dimensions and installation lengths of the sensor and transmitter can be found in the
"Technical Information" for the device in question. This document 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 →184.
3.2.2 Mounting location
The accumulation of air or gas bubbles in the measuring tube could result in an increase in
measuring errors.
Avoid the following locations:
• At the highest point of a pipeline. Risk of air accumulating.
• Directly upstream from a free pipe outlet in a vertical pipeline.
A0011899
Fig. 6: Mounting location
Installing 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 →165.
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 →161.

Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration. The Empty Pipe
Detection function offers additional protection by detecting empty or partially filled pipes →
125.
"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.
A0011901
Fig. 8: 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
(16,3 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.

3.2.3 Orientation
An optimum orientation position 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 problematic fluids:
• Electrode Cleaning Circuitry (ECC) to prevent electrically conductive deposits in the
measuring tube, e.g. for fluids causing buildup (see "Description of Device Functions"
manual).
• Empty Pipe Detection (EPD) ensures the detection of partially filled measuring tubes or in
the case of degassing fluids →125.
Vertical orientation
A vertical orientation is ideal in the following cases:
• For self-emptying piping systems and when using empty pipe detection.
• For sludge containing sand or stones and where the solids cause sedimentation.
A0011903
Fig. 10: 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 with the measuring device installed horizontally
only when the transmitter housing is facing upward (see diagram). Otherwise there is no
guarantee that Empty Pipe Detection will respond if the measuring tube is only partially
filled.

3.2.6 Foundations, supports
If the nominal diameter is DN 350 (14"), mount the sensor 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. 14: Correct support for large nominal diameters (DN  350 / 14")
3.2.7 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 only applies to liquids 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 fluid velocity
(downstream from the reduction) and the d/D ratio.

3.2.8 Nominal diameter and flow rate
The diameter of the pipe and the flow rate determine the nominal diameter of the sensor.
The optimum velocity of flow is between 2 and 3 m/s (6.5 to 9.8 ft/s)
The velocity of flow (v), moreover, has to be matched to the physical properties of the fluid:
• v < 2 m/s (v < 6.5 ft/s): for abrasive fluids

3.2.9 Length of connecting cable
In order to ensure measuring accuracy, please comply with the following instructions when
installing the remote version:
• Secure the cable run or route the cable in an armored 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.
• Ensure potential equalization between sensor and transmitter, if necessary.
• The permissible cable length Lmax depends on the fluid conductivity (→16).
• The maximum connecting cable length is 10 m (32.8 ft) when empty pipe detection
(EPD →125) is switched on.

3.3 Installation
3.3.1 Installing the Promag E sensor
"Caution!
• The protective covers mounted on the two sensor flanges guard the PTFE lining, which is
turned over the flanges. Consequently, do not remove these protection plates until
immediately before the sensor is installed in the pipe.
• Protection plates must remain in place while the device is in storage.
• Make sure that the lining is not damaged or removed from the flanges.
!Note!
Bolts, nuts, seals, etc. are not included in the scope of supply and must be supplied by the
customer.
The sensor is designed for installation between the two piping flanges:
• It is essential that you observe the necessary screw tightening torques on →20.
• If grounding disks are used, follow the mounting instructions which will be enclosed with
the shipment.
A0011908
Fig. 17: Installing the Promag E sensor
Seals
Comply with the following instructions when installing seals:
• PFA or PTFE lining seals are not required.
• Only use seals that comply with DIN EN 1514-1 for DIN flanges.
• Make sure that the seals do not protrude into the piping cross-section.
"Caution!
Risk of short circuit! Do not use electrically conductive sealing compound such as graphite.
An electrically conductive layer could form on the inside of the measuring tube and short-
circuit the measuring signal.
Ground cable
• If necessary, special ground cables can be ordered as accessories for potential equalization,
→128.
• For information on potential equalization and detailed installation instructions for using
ground cables, please refer to →62.
Screw tightening torques (Promag E)
Note the following points:
• The tightening torques listed below are for lubricated threads only.
• Always tighten the screws uniformly and in diagonally opposite sequence.
• Overtightening the screws will deform the sealing faces or damage the seals.
• The tightening torques listed below apply only to pipes not subjected to tensile stress.
