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 scope of supply mat-
ches 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.
Use webbing slings slung round 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
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.

3.1.3 Storage
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 10...+50 °C (preferably +20 °C).
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.
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 85 ff.
3.2.2 Mounting location
Correct measuring is possible only if the pipe is full. Avoid the following locations:
Highest point in the run. Risk of air accumulating
Directly upstream from an open pipe outlet in a down pipe.
Fig. 4: 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 79.
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 78.

Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration. The Empty
Pipe Detection function (see Page 54) 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. 6: 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. This precaution is to avoid low pressure and the consequent risk of damage 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 79.

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:
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 54).
Vertical orientation
This is the ideal orientation for self-emptying piping systems and for use in conjunction
with Empty Pipe Detection.
Fig. 8: 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. 9). Otherwise there is no
guarantee that Empty Pipe Detection will respond if the measuring tube is only partially
filled or empty.

3.2.4 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 DN
Outlet run 2 x DN
Fig. 10: Inlet and outlet runs
3.2.5 Vibrations
Secure the piping and the sensor if vibration is severe.
"Caution:
Information on resistance to vibration and shock can be found on Page 78.

3.2.6 Adapters
Suitable adapters to (E) 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 applies to fluids 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 2…3 m/s. The velocity of flow (v), moreover, has to be
matched to the physical properties of the fluid:
v < 2 m/s: for abrasive fluids
v > 2 m/s: for fluids producing build-up
!Note:
Flow velocity can be increased, if necessary, by reducing the nominal diameter of the
sensor (see Page 17).

3.3 Installation
3.3.1 Installing the Promag P sensor
"Caution:
The protective covers mounted on the two sensor flanges guard the Teflon (PTFE)
lining, which is turned over the flanges. Consequently, do not remove these covers
until immediately before the sensor is installed in the pipe.
The covers 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:
Observe in any case the necessary screw tightening torques on Page 23 ff.
The mounting of additional ground disks is described on Page 21.
Fig. 13: Installing the Promag P sensor
Seals
Comply with the following instructions when installing seals:
Measuring tube linings with PFA or PTFE No seals are required.
In case you use seals with DIN flanges, use only seals according to DIN 2690.
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 gra-
phite. An electrically conductive layer could form on the inside of the measuring tube
and short-circuit the measuring signal.
Ground cable (DN 25…200)
If necessary, a special ground cable for potential equalisation can be ordered as an
accessory (see Page 59). Detailled assembly instructions Page 36 ff.
