• All parts of the device must be included in the potential equalization of the system.
• Cables, certified cable glands and certified dummy plugs must be suitable to withstand the
prevailing operating conditions, such as the temperature range of the process. Housing
apertures that are not used must be sealed with dummy plugs.
• The device should only be used for fluids to which all the wetted parts of the device are
sufficiently resistant. With regard to special fluids, including fluids used for cleaning,
Endress+Hauser will be happy to assist in clarifying the corrosion-resistant properties of
wetted materials.
However, minor changes in temperature, concentration or in the degree of contamination in
the process may result in variations in corrosion resistance.
For this reason, Endress+Hauser does not accept any responsibility with regard to the
corrosion resistance of wetted materials in a specific application. The user is responsible for
the choice of suitable wetted materials in the process.
• When hot fluid passes through the measuring tube, the surface temperature of the housing
increases. In the case of the sensor, in particular, users should expect temperatures that can
be close to the fluid temperature. If the temperature of the fluid is high, implement sufficient
measures to prevent burning or scalding.
• Hazardous areas
Measuring devices for use in hazardous areas are labeled accordingly on the nameplate.
Relevant national regulations must be observed when operating the device in hazardous areas.
The Ex documentation on the CD-ROM is an integral part of the entire device documentation.
The installation regulations, connection data and safety instructions provided in the Ex
documentation must be observed. The symbol and name on the front page provides
information on the approval and certification (e.g. 0Europe, 2USA,
1Canada). The
nameplate also bears the documentation number of this Ex documentation (XA***D/../..).
• For measuring systems used in SIL 2 applications, the separate manual on functional safety
(on the CD-ROM) must be observed.
• Hygienic applications
Measuring devices for hygienic applications have their own special labeling. Relevant national
regulations must be observed when using these devices.
• Pressure instruments
Measuring devices for use in systems that need to be monitored are labeled accordingly on the
nameplate. Relevant national regulations must be observed when using these devices. The
documentation on the CD-ROM for pressure instruments in systems that need to be
monitored is an integral part of the entire device documentation. The installation regulations,
connection data and safety instructions provided in the Ex documentation must be observed.
• Endress+Hauser will be happy to assist in clarifying any questions on approvals, their
application and implementation.

2.2 Installation conditions
2.2.1 Dimensions
For the dimensions of the measuring device, see the associated Technical Information on the
CD-ROM.
2.2.2 Mounting location
The accumulation of air or formation of gas bubbles in the measuring tube can result in an
increase in measuring errors.
For this reason avoid the following mounting locations in the pipe:
• At the highest point of a pipeline. Risk of air accumulating!
• Directly upstream from a free pipe outlet in a down pipe.

0008154
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. It might be necessary to
use pulse dampers in systems incorporating piston pumps, piston diaphragm pumps or peristaltic
pumps.
Information on the measuring system's pressure tightness and resistance to vibration and shock
can be found in the Operating Instructions of the CD-ROM.

Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration.
The empty pipe detection (EPD) function 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.
Down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes longer than 5 meters
(16 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 pockets.
For information on the pressure tightness of the measuring tube lining, see the Operating
Instructions on the CD-ROM.

2.2.3 Orientation
An optimum orientation helps avoid gas and air accumulations and buildup in the measuring
tube. The measuring device, nevertheless, supplies a range of functions and tools to measure
problematic fluids correctly:
• Electrode cleaning circuitry (ECC) to prevent electrically conductive deposits in the
measuring tube, e.g. for fluids causing buildup
• Empty pipe detection (EPD) for detecting partially filled measuring tubes, e.g. in the case of
degassing fluids or varying process pressures
• Exchangeable measuring electrodes for abrasive fluids (only Promag W)
Vertical orientation
Horizontal orientation
The measuring electrode plane should be horizontal. This prevents brief insulation of the two
electrodes by entrained air bubbles.
"Caution!
In the case of horizontal orientation, empty pipe detection only works correctly if the transmitter
housing is facing upwards. Otherwise there is no guarantee that empty pipe detection will
respond if the measuring tube is only partially filled or empty.
A0008158
This orientation is optimum for self-emptying piping
systems and when using empty pipe detection (EPD) or
open electrode detection (OED).

2.4 Installing the W sensor
2.4.1 Seals
Comply with the following instructions when installing seals:
• Hard rubber lining →additional seals are always necessary.
• Polyurethane lining →no seals are required.
• For DIN flanges, use only seals according to EN 1514-1.
• Make sure that the seals do not protrude into the piping cross-section.
"Caution!
Risk of short circuit!
Do not use electrically conductive sealing compounds such as graphite! An electrically
conductive layer could form on the inside of the measuring tube and short-circuit the measuring
signal.
2.4.2 Ground cable
If necessary, special ground cables can be ordered as accessories for potential equalization.
a0008165
!Note!
Screws, nuts, seals, etc. are not included in the scope of
supply and must be supplied by the customer.
The sensor is installed between the two pipe flanges:
• The requisite torques must be observed → ä18
• If grounding disks are used, follow the mounting
instructions which will be enclosed with the
shipment.
• To comply with the device specification, a
concentrical installation in the measuring section is
required
