Application-specific QUICK SETUPs Page 85 ff.
In “Quick Setup” mode you have the option of launching other, application-
specific Quick Setups, for instance the menu for measuring pulsating flow.
▼
Customer-specific configuration Page 65 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.

3.1 Incoming acceptance, transport and storage
3.1.1 Incoming acceptance
•Check the packaging and the contents for damage.
•Check the shipment, make sure nothing is missing and that the contents 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 the
device is ready to install. This is particularly important in the case of sensors with
Teflon linings.
Special notes on flanged devices
"Caution:
•The wooden covers mounted on the flanges before the device leaves the factory pro-
tect 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 (D ≤12" / DN ≤300):
Use webbed slings around the two process connections (Fig. 3). 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 meas-
uring device might be higher than the points around which the slings are.
At all times, therefore, make sure that the device does not unexpectedly turn around its
axis or slip.

3 Installation PROline Promag 53
14 Endress+Hauser
Transporting flanged devices (D ≥14" / DN ≥ 350):
Use only the metal eyes on the flanges for transporting the device, lifting it and position-
ing 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.
Fig. 4: Transporting sensors with D ≥14" / DN ≥ 350
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 permissible storage temperature is 14 to 122 °F / −10 to +50 °C (preferably 68 °F
/ 20 °C).
•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
Teflon linings.

3.2 Installation conditions
3.2.1 Dimensions
Dimensions and the fitting lengths of the transmitter and sensor are on Page 136 on.
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. 5: 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. Infor-
mation on the lining's resistance to partial vacuum can be found on →Page 127.
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 124.

Partially filled pipes with gradients necessitate a drain-type configuration. The Empty
Pipe Detection function (see Page 91) 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. 7: Installation in partially filled pipe
Down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes longer than 16
ft. (5 meters). This precaution is to avoid low pressure and the consequent risk of dam-
age 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 127.

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 accesso-
ries for correct measuring of problematic fluids:
•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 or varying process pressures (see Page 91)
•Exchangeable Measuring Electrodes for abrasive fluids (see Page 117)
Vertical orientation
This is the ideal orientation for self-emptying piping systems and for use in conjunction
with Empty Pipe Detection.
Fig. 9: 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 horizon-
tally only when the transmitter housing is facing upward (Fig. 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 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 D
•Outlet run ≥2 x D

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 124.

3.2.5 Foundations, supports
If the nominal diameter is ≥14" (DN ≥350), mount the transmitter on a foundation of ade-
quate 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.

3.2.6 Adapters
No pressure loss if the sensor is installed in a pipe of the same nominal diameter. Pres-
sure losses occur in configurations incorporating adapters (reducers, expanders). Con-
tact your Endress+Hauser representative or Endress+Hauser for information.
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 6 to 10 ft/s (2 to 3 m/s). The velocity of flow (v), moreover,
has to be matched to the physical properties of the fluid:
•v < 6 ft/s (2 m/s): for abrasive fluids such as potter's clay, lime milk, ore slurry, etc.
•v > 6 ft/s (2 m/s): for fluids producing buildup such as wastewater sludge, etc.
!Note:
Flow velocity can be increased, if necessary, by reducing the nominal diameter of the
sensor (see Section 3.2.6).
