3 Mounting and Installation
Warning!
•The instructions given in this section are to be observed at all times in order to
ensure safe and reliable operation of the measuring system.
•For explosion protected instruments the mounting regulations and the technical
data may differ from those stated here. Please refer to the Ex supplement of this
Operating Manual for additional information.
3.1 Transport instructions (DN ≥350/14")
The pipe lining on the flanges is protected by disks to prevent damage when
transporting to the measuring point. These are to be removed when installing.
Instruments are to be transported in the containers they are delivered in.
Transporting to the measuring point
•The sensor must not be lifted by the
transmitter housing!
•Use only the grips on the flange for
lifting out and mounting the sensor in
the piping (from DN 350 or 14").
Caution!
The sensor must not be lifted by the
metal casing using a fork lift truck!
This can buckle the casing and so
damage the internal magnetic coils.
Base and supports
The sensor is to be mounted on a base
which is sufficiently strong enough to
withstand its weight.
Caution!
Do not support the sensor by the sheet
casing. The casing may be dented and
so damage the magnetic coils inside
the sensor.
Warning!

3.2 Mounting location
Correct measurement is only possible
when the pipe is full. The following
locations should therefore be avoided:
•No installation at the highest point
(air accumulation).
•No installation immediately before
an open pipe outlet in a downward
line.
The alternative installation, however,
enables correct measurement.
Partly filled pipes
For inclines a mounting similar to a drain
should be adopted.
Added security is offered by Empty Pipe
Detection in order to detect empty or
partly filled pipes (see page 73).
Note!
Danger of solids accumulation!
Do not mount the sensor at the lowest
point of the drain. A cleaning valve
should also be installed.
Downward pipe
With the installation suggested opposite,
partial vacuum is avoided even with a
downward pipe > 5 m long (siphon, vent
valve downstream of the sensor).

3 Mounting and Installation Promag 33
10 Endress+Hauser

Installation of pumps
Do not mount the sensors on the
suction side of pumps. This prevents
low pressure and therefore possible
damage to the lining of the measuring
tube.
Information on the resistance to vacuum
of the flowmeter lining can be found on
page 115.
Pulse dampers should be installed
when using reciprocal, diaphragm or
peristaltic pumps.
Vibration
The piping before and after the sensor
should be securely fastened if there
is excessive vibration.
Information on shock and vibration
resistance is found on page 110.
Caution!
Excessive vibration necessitates
separate mounting of the sensor and
transmitter (see pages 20, 109).
Mechanical support of the sensor is
recommended for free runs of piping
over 10 m long.
Caution!

Promag 33 3 Mounting and Installation
Endress+Hauser 11

3.3 Mounting position
Vertical mounting:
This is the recommended position with
the flow upwards. Entrained solid
particles sink and fatty components in
the stationary fluid rise away from the
measuring electrodes. This is the
optimal position in empty pipe system
and when using Empty Pipe Detection
(see page 73).
Horizontal mounting:
The axis of the electrodes must be
horizontal, thus preventing brief insula-
tion of the electrodes by entrained air
bubbles.
Electrode axis:
The plane in which the electrode axis
lies with regard to the transmitter is
identical for the Promag A, H and F
sensors.
Inlet and outlet sections
The sensor should by mounted away
from fittings such as valves, T-pieces,
elbows, etc.
Inlet section: ≥5 x DN
Outlet section: ≥2 x DN
The inlet and outlet sections must be
observed in order to maintain accuracy.

3.4 Nominal diameter and flow rate
The diameter of the pipe usually governs the nominal diameter of the sensor.
The optimum flow velocity range is between v = 2...3 m/s. Furthermore, the flow
velocity (v) has to be matched to the physical properties of the fluid:
•v < 2 m/s →with abrasive fluids (potter’s clay, lime milk, ore slurry)
•v > 2 m/s →with fluids forming coating (wastewater sludge, etc.)
If it is necessary to increase the flow velocity, this can be done by reducing the
nominal diameter of the sensor (see following chapter).

3.5 Adapters
The sensor can also be mounted in a pipe with a larger nominal diameter when
suitable adapters (reducers and expanders) to DIN 28545 are fitted.
The resultant increase in the rate of flow increases the accuracy of measurement
with slowly moving fluids.
The adjacent nomogram can be used to
determine the pressure loss caused.
Procedure:
1. Determine the ratio of the
diameter d/D.
2. From the nomogram read off the
pressure loss at the flow velocity and
d/D ratio.
Note!
The nomogram applies to fluids with a
viscosity similar to that of water.

3.6 Mounting Promag A sensor
Various process connections are available for the Promag A sensor.
The process connections (adapters) are mounted in two ways:
A.
Coupling nut on a 1" threaded stub (mounting set)
•Internal thread
•External thread
•PVC adhesive coupling
•Hose connection
•Weld nipples
B.
Screw-in process connections (instead of threaded stub)
These process connections are mounted as standard in the factory before delivery.
•Flange joints
•Tri-Clamp
Seals / Screw tightening torques (Mounting set)
When fastening the process connections, the O-ring or the flat seal is pressed fully
into the seal groove in the threaded stub. The skirted nut thereby comes to a fixed
stop.
Length, Dimensions →see pages 99 ff.

3.7 Mounting Promag H sensor
The Promag H sensor is delivered with the process connection already mounted.
The various process connections are fastened to the sensor with 4 or 6 screws.
Seals / Screw tightening torques
When mounting the process connectors,
make sure that the seal is free of dirt
and correctly centered. The screws have
to be tightened.
The process connector forms a metal
connection with the sensor, to guarantee
a pre-defined seal compression.
The gaskets must be replaced at
frequent intervals!
Length, Dimensions →see pages 102 ff.
Welding the sensor into the pipework (welded nipple)
If the sensor is directly welded into the pipework, we recommend the following
procedure:
Caution!
The electronics may be destroyed! Take care that the welding ground is not via
the Promag 33 H sensor or housing.
1. Fasten the Promag H sensor with some spot welds into the pipe.
2. Loosen the screws at the process-connector flange and remove the sensor from
the pipe; make sure that the seal is also removed from the process connector.
3. Weld the process connector into the pipe.
4. Once again install the sensor into the pipe; making sure everything is clean and
the seal is correctly positioned.
Note!
•If the welding process is correctly executed in thin-walled food piping, the seal will
not be damaged by the heat, even when mounted. Nevertheless, we recommend re-
moving the sensor and seal first.
•For the disassembly, the pipe has to be spread by about 4 mm.

The sensor is mounted between the flanges of the piping (Fig. 15). Since the lining of
the measuring tube also covers the sensor flange, it also acts as a seal.
Caution!
The Teflon (PTFE) lined Promag F is fitted with protective disks to guard the lining
which is turned over the flanges. These disks are to be removed just before mounting
the sensor. Ensure that the lining on the flange is not damaged or removed.
These disks must remain in position during storage.
Seals
•If the measuring tube liner is made of soft rubber or Teflon (PTFE), a flange seal
is not required.
•With soft rubber lining the mating flange should have a thin film of non-conductive
sealing grease applied.
•Use a seal according to DIN 2690.
•Mounted seals must not protrude into the piping section.
Caution!
Danger of short-circuit! Do not use sealing materials that are electrically conductive,
e.g. graphite. This could result in an electrically conductive layer forming on the inside
of the measuring tube and therefore short-circuiting the measuring signal.

3.9 Turning the transmitter housing and local display
The transmitter housing and local display can be rotated in steps of 90°. This enables
the unit to be adapted to different mounting positions in the piping and so simplifying
reading and operation.
Warning!
For instruments with EEx d/de or FM/CSA Cl. I Div. 1 approval, the procedure for
rotating the instrument is different than that described here and is given in the
Ex-supplement to this documentation. Warning!

3.10 Mounting the transmitter (remote version)
The transmitter has to be mounted remote from the sensor when:
•access is difficult,
•space is restricted,
•extreme process and ambient temperatures prevail (for temperature ranges
see page 110),
•there is severe vibration (> 2 g/2 h per day; 10...100 Hz).
Wall and post mounting
The remote mounted version is delivered
with a wall bracket as standard.
A special mounting set can be supplied
for post mounting: Order No. 50076905.
Connecting cable
Two different versions are available
for remote versions:
FS version:
•The permissible length of cable
Lmax of more than 10 m is governed
by the conductivity of the fluid
(see Fig. 19).
•The maximum possible cable length is
limited to 10 meter for instruments with
Empty Pipe Detection (EPD). This
function is only available with the
FS version.
•The FS cable is recommended only for
distances smaller than 20 m.
FL version:
•All fluids with a minimum conductivity
of ≥5µS/cm (demineralised water
≥20 µS/cm) can be measured.
This is not dependent on the distance
between transmitter and sensor
(see Fig. 19).
•Empty Pipe Detection (EPD) is
not
available with this version.
Please also note the following for
obtaining correct readings:
•Fasten the cable gland or lay it in a
conduit. When the fluid conductivity is
low, cable movements can cause
serious changes in capacitance and
thereby falsify the measuring signal.
•Do not run the cable in the vicinity of
electrical machines or switching
elements.
•Ensure potential equalisation between
the transmitter and the sensor.
