3.1 Incoming acceptance, transport and storage
3.1.1 Incoming acceptance
On receipt of the goods, check the following:
• 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 from the factory protect the linings on the
flanges during storage and transportation. In case of Promag L they are additionally used
to hold the lap joint flanges in place. Do not remove these covers until immediately before
the device 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 (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.

Endress+Hauser 11
Transporting flangeddevices DN  350 (14")
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  350 (14")
3.1.3 Storage
Please note the following:
• 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 →102.
• 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 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 →127.
3.2.2 Mounting location
Entrained air or gas bubble formation 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 from a free pipe outlet in a vertical pipeline.
A0008154
Fig. 6: Mounting 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 →107.
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 →103.

Promag 50 Installation
Endress+Hauser 13
Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration.
The Empty Pipe Detection function (EPD →76) 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. 8: Installation in a partially filled pipe
Down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes whose length
h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 pockets.
Information on the lining's resistance to partial vacuum can be found on →107.

3.2.3 Orientation
An optimum orientation position helps avoid gas and air accumulations and deposits in the
measuring tube. However, Promag offers the additional Empty Pipe Detection (EPD)
function to ensure the detection of partially filled measuring tubes, e.g. in the case of
degassing fluids or varying process pressure:
• Electrode Cleaning Circuit (ECC) for applications with accretive fluids, e.g. electrically
conductive deposits ("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 (→76)
• Exchangeable Measuring Electrodes for abrasive fluids (→95)
Vertical orientation
This is the ideal orientation for self-emptying piping systems and for use in conjunction with
Empty Pipe Detection.
A0008158
Fig. 10: Vertical orientation
Horizontal orientation
The measuring electrode plane should be horizontal. This prevents brief insulation of the
two measuring 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 (→10). Otherwise there is no
guarantee that Empty Pipe Detection will respond if the measuring tube is only partially
filled or empty.

Inlet and outlet run
If possible, install the sensor upstream from fittings such as valves, T-pieces, elbows, etc. The
following inlet and outlet runs must be observed in order to meet accuracy specifications:
• Inlet run: 5 × DN
•Outletrun:2 × DN
A0003210
Fig. 12: Inlet and outlet runs
3.2.4 Vibrations
Secure the piping and the sensor if vibration is severe.
"Caution!
If vibrations are too severe, we recommend the sensor and transmitter be mounted
separately. Information on resistance to vibration and shock can be found on →103.

3.2.5 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")
3.2.6 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 reducers and expanders.
!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 flow velocity
(downstream from the reduction) and the d/D ratio.

3.2.7 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
• v > 2 m/s (v > 6.5 ft/s): for fluids producing buildup
!Note!
Flow velocity can be increased, if necessary, by reducing the nominal diameter of the sensor
(→16).

3.2.8 Length of connecting cable
In order to ensure measuring accuracy, comply with the following instructions when
installing the remote version:
• Fix cable run or lay in armored conduit. Cable movements can falsify the measuring signal
especially in the case of low fluid conductivities.
• Route the cable well clear of electrical machines and switching elements.
• Ensure potential equalization between sensor and transmitter, if necessary.
• The permitted connecting cable length Lmax is determined by the fluid conductivity (→
16). 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 connecting cable length is 10 m (32.8 ft) when empty pipe detection
(EPD →76) is switched on.

3.3 Installation instructions
3.3.1 Installing the Promag D sensor
The sensor is installed between the pipe flanges with a mounting kit. The device is centered
using recesses on the sensor (→21).
!Note!
A mounting kit consisting of mounting bolts, seals, nuts and washers can be ordered
separately (→79). Centering sleeves are provided with the device if they are required for
the installation.
"Caution!
When installing the transmitter in the pipe, observe the necessary torques (→22).

Seals
When installing the sensor, make sure that the seals used do not project into the pipe 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.
!Note!
Use seals with a hardness rating of 70° Shore A.
