1. System description
1.1 Areas of application
The Magphant flow monitor provides the plant system with the information needed on
flowrate in the piping. The magnetic-inductive measuring principle determines the
flow velocity of the conductive liquid at the tip of the sensor. Exceeding the preset
switchpoint (limit value) is indicated by a relay contact. An analogue 4...20 mA signal
proportional to the flow is also available for monitoring the flowrate at the same time.
The Magphant is ideal for process protection and monitoring.
1.2 Measuring principle
In accordance with Faradays law of magnetic induction, a voltage is induced in a con-
ductor that is moved through a magnetic field. In the electromagnetic principle of
measurement the flowing fluid represents the moving conductor. The induced voltage
is proportional to the flow velocity and is fed to the measuring amplifier by a pair of
electrodes.
Microprocessor-controlled electronics, with a stable zero-point, convert the voltage
into an analogue 4...20-mA output signal.
Ue= B x L x v = induced voltage
B = magnetic induction (magnetic field)
L = distance between electrodes
v = flow velocity at the tip of the sensor

2. Mounting and Installation
2.1 Protection type IP 66 (DIN 40050)
The Magphant fulfils all the requirements for IP 66.
Caution!
After successful installation in the field or after replacing an instrument, the following
points must always be observed in order to ensure protection to IP 66:
•Housing gaskets must be clean and undamaged and lie at the end of the cover
threads. The gaskets may need to be dried, cleaned or replaced.
•The screw cover must be firmly tightened.
•The cables used for connecting must have an outer diameter of 7...12 mm.
•The cable glands must be firmly tightened.
•The cable must loop down before entering the cable gland to ensure that no mois-
ture can enter it.
•An unused cable gland is to be replaced with a blind plug.
•The protective bush should not be removed from the cable gland.
2.2 Temperature ranges
Caution!
•The maximum approved ambient and fluid temperatures must be observed
(see Page 20).
•For outside installation of the instrument, take care that it is protected from direct
sunlight. This applies especially in countries with high ambient temperatures.

2.3 Mounting instructions
Orientation in the piping
The Magphant is best mounted in vertical piping.
If the piping runs horizontally, then the Magphant is to be mounted to the side.
This mounting procedure ensures that the electrodes are always immersed in flowing
fluid.
Caution!
Never weld the weld stub to the pipe with the Magphant in place.
Position of the electrode axis
The sensor is to be mounted so that the electrode axis is always 90° to the direction of
flow. The two PG 16 cable glands can be used as a visual check as these also lie on
the same axis.

2.4 Mounting in steel piping
The Magphant is mounted in steel piping using the weld stub supplied.
Two different versions are available, depending on nominal diameter:
Weld stub for DN 25
For DN 25 piping, the weld stub has the appropriate radius to match the diameter.
•Opening in the piping: ∅= 23 mm.
•Place the weld stub on the opening and weld it at right angles to the axis of the
piping.
Weld stub for ≥DN 40
For ≥DN 40 piping, the weld stub has a graduated scale to ensure that the stub can
be correctly positioned for mounting.
•Opening in the piping: ∅= 30 mm.
•Insert the weld stub into the opening, with the marking (according to the nominal
diameter) flush against the outer wall of the piping and weld it at right angles to the
axis of the piping. For diameters >DN 300, the DN 300 marking is to be used.

Mounting in plastic piping for diameters ≥DN 65
A plastic weld stub is used for mounting in plastic piping for diameters ≥DN 65.
These plastic weld stubs can be obtained from the Georg Fischer company in PVC,
PP and PE materials.
The L dimension must be adjusted by the customer accordingly, depending on the
pipe outer diameter.
The L dimension can be calculated based on the following formula:
S = pipe wall thickness
E = insertion depth of the plastic weld nipple
(E can be obtained from the table below)

Potential equalization
The Magphant should be connected to ground via the ground terminal at the housing
to ensure complete electromagnetic compatibility.
Note!
Take care that the ground cable is kept as short as possible.
3.3 Commissioning
Before switching on the measuring system, the following checks should be carried
out:
•Does the directional arrow on the Magphant agree with the actual flow direction,
i.e. do the two PG 16 cable glands lie at 90° to the direction of flow?
•Check the electrical connections and terminal assignments as shown on Page 13.
•Check that the local power supply agrees with the information stated on the name-
plate.
The following procedure should now be carried out:
1. Set miniature switch 1 (test mode) to the "normal" position (see Page 17).
2. Set the miniature switches 2 to 4 for
– time constant / relay latch time
– relay function
– min. / max. fail-safe
as appropriate.
3. After switching on the power supply, the outputs are deactivated for 5s (relay de-
energised and current output remains at 0 mA). Both LEDs flash during this proce-
dure.
4. Set the full-scale value. This can be done in two ways:
Full-scale value with actual flow (local calibration)
– Take into account general flowrates anticipated.
– Turn the full-scale potentiometer until the green LED lights up (see Page 16).
Setting the full-scale value without actual flow
– Set the full-scale potentiometer at the mean flow rate anticipated.
5. Use the limit switch to set the relay switchpoint in % of the preset full-scale as
described in Point 4.
Note!
A detailed description of the display and operating elements is given on Page 15/16.

(factory setting) Description of function
Time constant / Relay latch time
The times t = 3 s and t =10 s correspond to the current
output time constant and also to the relay latch time.
t = 3 s: The relay switches immediately and then remains
in this state for 3 seconds.
t = 10 s: The relay first switches when the measured value
is below or above the limit value for a continuous
10 seconds.
Relay functions
The relay is energised if all functions are operating
correctly. The relay is de-energised immediately when an
error or alarm occurs.
limit
The relay de-energises or the red LED lights up if the
signal moves outside the upper or lower limit value
(depending on the min./max. fail-safe setting).
(limit) + error
The same function as for "limit", but in addition:
The relay de-energises if the flow rate is larger than the
measurable value of the Magphant or if an instrument error
occurs. The red LED flashes. "Error" has higher priority
than "limit".

5. Troubleshooting and Remedies
5.1 Response of the measuring system to faults
•Error messages which occur during measurement are always indicated via the
current and, depending on the preset relay function, also via the relay output.
•In addition, a system or process error is always indicated when the red LED flashes.
5.2 Checking the electronics
The Magphant can be set to a test mode using miniature switch No. 1:
1. Set test mode switch to "test".
2. Turn the full-scale potentiometer anticlockwise until it comes to the mechanical
stop, the current output must now be exactly 20 mA.
3. If this is not the case, then the electronics module must be replaced.
