Product introduction

1. Product introduction

MAGFLOâ electromagnetic flowmeters offer reliable, precise and inexpensive flow measure­ment on all electrically conductive liquids. Typical applications are found in all industries. E.g.:

• Water sector: Potable water, treatment of chemicals, waste water and sludge.

• Food sector: Dairy products, beer, wine, soft-drinks and fruit juices.

• Chemical sector: Detergents, pharmaceuticals, acids and alkalies.

• Other sectors: HVAC, paper pulp and mining slurries.

MAGFLOâ electromagnetic flowmeters are characterised by simplicity:

Þ Simple to install
Þ Simple to commission
Þ Simple to operate
Þ Simple to maintain

MAGFLO

â

electromagnetic flowmeters are manufactured by Danfoss A/S, Flow Division - one of

the worlds leading makers of flowmeters.

All MAGFLOâ electromagnetic flowmeters feature a unique SENSORPROM® memory unit which
stores sensor calibration data and signal converter settings for the lifetime of the product.
At commissioning the flowmeter commences measurement without any initial programming.

The factory settings matching the sensor are stored
in the SENSORPROM® unit. Also customer specified
settings are downloaded to the SENSORPROM

®

unit. Should the signal converter be replaced, the
new converter will upload all previous settings and
resume measurement without any need for re­programming.
Furthermore, the "fingerprint" used in connection
with the Danfoss Verificator is stored during the sen­sor calibration.
The Danfoss Verificator can verify the accuracy of
the flowmeter while still installed years after the
initial calibration.

USM II "Plug & Play" add-on communication mo­dules.

USM II - the Universal Signal Module with "Plug &
Play" simpl ic it y makes it e asy to access and
integrate the flow measurement with almost any
system. It ensures the flowmeter will be easy to
upgrade to new communication platforms in the
future, too.

Mode of operation

Ui = When an electrical conductor of length L is moved at velocity v, perpendicular to the lines of
flux through a magnetic field of strength B, the voltage Ui is induced at the ends of the conductor

Ui = L x B x v

Ui= Induced voltage
L = Conductor length = Inner pipe diameter = k

1

B = Magnetic field strength = k

2

v = Velocity of conductor (media)
k = k1 x k

2

Ui = k x v, the electrode signal is directly proportional to the fluid velocity

SENSOR (Flow tube)

The sensor converts the flow into an electrical voltage (U

i

) proportional to the velocity of the flow.
The sensor is built up of a stainless steel pipe, 2 coils, electrodes, an isolating liner, housing and
where applicable, connecting flanges.

SIGNAL CONVERTER

The signal converter consists of a number of function blocks which convert the sensor voltage into
flow readings.

Power supply

2 different types of power supply are available. A 12 - 24 V a.c./d.c. and a 115 - 230 V a.c. switch
mode type.

Coil current module generates a pulsating magnetizing current that drives the coils in the sensor.
The current is permanently monitored and corrected. Errors or cable faults are registered by the self­monitoring circuit.

Input circuit amplifies the flow proportional signal from the electrodes. The input impedance is
extremely high: >10

14

W which allows flow measurements on fluids with conductivities as low as

1 mS/cm. Measuring errors due to cable capacitance are eliminated due to active cable screening.

Digital signal processor converts the analog flow signal to a digital signal and suppresses
electrode noise through a digital filter. Inaccuracies in the signal converter as a result of long-term
drift and temperature drift are monitored and continuously compensated for via the self-monitoring
circuit. The analog to digital conversion takes place in an ultra low noise ASIC with 23 bit signal
resolution. This has eliminated the need for range switching. The dynamic range of the signal
converter is therefore unsurpassed with a turn down ratio of minimum 3000:1.

CAN communication

The signal converter operates internal via an internal CAN communication bus. Signals are
transferred to/from a signal conditioner to the display module, internal/external option modules and
the dialog module.

Dialog module

The display unit consists of a 3-line display and a 6-key keypad. The display shows a flow rate or
a totalizer value as a primary reading.

Output module converts flow data to an analog, a digital and a relay output. The outputs are
galvanically isolated and can be individually set to suit a particular application.

The flow measuring principle is based on Faraday’s law of electromagnetic induction. The flowmeter
consists of a sensor type MAG 1100, 3100 or 5100 W and a signal converter type MAG 5000 or 6000.

The sensor must be mounted as shown in the
left figure. Do not mount the sensor as shown in
the right figure. This will position the electrodes
at the top where there is possibility for air bubbles
and at the bottom where there is possibility for
mud, sludge, sand etc.

Recommended installation is in a vertical/in­clined pipe to minimize the wear and deposits
in the sensor.

To achieve accurate flow measurement it is
essential to have straight lengths of inlet and
outlet pipes and a certain distance between
pumps and valves.
It is also important to center the flowmeter in
relation to pipe flanges and gaskets.
For accurate flow measurement, the sensor
must be installed in a section of straight pipe,
free of valves, elbows, tees, etc.

containing particles

Inlet and outlet conditions

Avoid:

· Installation at the highest point in the pipe
system

· Installation in vertical pipes with free outlet

For partially filled pipes or pipes with downward
flow and free outlet the flowmeter should be
located in a U-tube.

Recommended flow direction: upwards. This
minimizes the effect on the measurement of any
gas/air bubbles in the liquid.

Installation in vertical pipes

3.3
Installation conditions

(continued)

To ensure optimum flow measurement, atten­tion should be paid to the following:
The sensor must always be completely full with
liquid.

Avoid a vacuum in the measuring pipe, since
this can damage certain liners.

The flowmeter can be installed between two
reducers.

A flow velocity of 10 ft./sec. (V) in a sensor with
a diameter reduction from 4" to 3" (d1/d2 = 0.8)
gives a pressure drop of 0.04 psi.

Installation in large pipes

The electrical potential of the liquid must al­ways be equal to the electrical potential of the

sensor. This can be achieved in different ways
depending on the application:
A. Built-in grounding electrodes. (MAG 3100

and MAG 3100 W).

B. Direct metallic contact between sensor and

fittings. (MAG 1100 FOOD).

C. Wire jumper between sensor and adjacent

flanges. (MAG 1100 and MAG 3100).

D. Optional graphite gaskets on MAG 1100.

(Standard for MAG 1100 High temperature).

Suggestions for the direct
burial of MAG 3100 &
MAG 5100 W sensors

If MAGFLO 3100 or MAG 5100 W sensors are buried directly into the ground, we suggest the
following precautions:

The SENSORPROMâ unit should be removed from the terminal box on the sensor and relocated
in the signal converter remote mounting prior to burying the sensor.

All the sensor data plate information and serial number should be recorded for each sensor prior
to burying. This will ensure correct matching with the SENSORPROM

â

unit.

The sensor should be potted with the optional IP68 submersion kit and suitable coil and
electrode cables should be used prior to burying.

The use of pea gravel, at least 12 inches all around the sensor, is recommended. This provides
some drainage and prevents dirt from caking onto the sensor. It also helps locate the sensor
should excavation be necessary.

Before covering the pea gravel with earth, we suggest the use of electrical cable identification
tape laid above the gravel.

The sensor should not be subject to heavy vehicles applying excessive weight above the sensor
or pipeline.

NEMA 6 submersible kit
(option)

If the sensor is going to be buried or per­manently submerged, the terminal box must
be encapsulated with silicon dielectric gel.
The optional kit has two components.
Mix the two components well (without inducing
air) and pour the contents into the terminal box.
The material is a non-toxic, transparent, self­healing gel which cures in approx. 24 hours.
The gel can be penetrated with test instru­ments or be removed in case of cable replace­ment.

The Danfoss cleaning unit can be used with MAG 5000 or 6000 in rack mount versions.
The cleaning unit can be used in applications where the liner material and subsequently the
electrodes may be coated with deposits. If the coating is electrically insulating, the electrode signal
will be reduced. If the coating is electrically conductive, the electrode signal will be partly short­circuited. In both cases the accuracy of the meter will decrease (dependent on the type and thickness
of the coating).

Note

The cleaning unit cannot be used for flammable or explosive media!
Empty pipe detection and cleaning facility cannot be used at the same time.

The cleaning unit cleans the electrodes electro-chemically by applying a voltage to the electrodes
for approx. 60 sec. While cleaning, the signal converter stores and holds the latest measured flow
reading on the display and also the signal outputs. After an additional pausing period of 60 sec. the
flowmeter resumes normal measurement and the cleaning is now completed.

The relay in the signal converter activates the cleaning cycle. In the relay output menu (under
cleaning) the cleaning interval can be set between 1 hour and 24 hours.

Cleaning should only take place with liquid in the pipe. This can be achieved via the empty pipe
detection. It is therefore recommended to select “empty pipe detection” ON when using the cleaning
unit.

The cleaning sequence can also be controlled manually through the electrical input of the signal
converter. Before this is done, ensure that the measuring pipe is full.

Theory of operation

3.4
Cleaning unit

AC-cleaning

(For non-conductive coatings)

DC-cleaning

(For conductive coatings)

AC-cleaning is used to remove fatty deposits on the electrodes. Fatty deposits are seen from
Slaughter houses and in rare instances from wastewater applications and water applications with
oil residuals. During the cleaning process, the surface of the electrodes get warmer, which tends
to soften grease particles and the gas bubbles generated mechanically lift deposits away from the
surface of the electrodes.

DC-cleaning is used to eliminate electrically conductive deposits in the measuring pipe influencing
the measuring accuracy.
Particularly in district heating applications, an electrically conductive deposit (magnetite) may occur
and short-circuit the electrode signal. In this case the accuracy of the meter decreases and the signal/
noise conditions of the meter become inferior. The problem only arises if the conductivity of the water
is less than approx. 250 mS/cm.

During DC-cleaning, electrolysis takes place where the flow of electrons removes the particle
deposits from the electrode area.

A signal converter can be supplied in a version
tested and approved for custody transfer (CT).
The internal counter can accordingly be used
for billing.
This requires verification, sealing and setting of
the signal converter together with the sensor for
a specific flow range. After sealing, the data on
the signal converter must not be changed.

Marking

The marking has the following meaning according to European Norm EN 50014.

E: Certified to CENELEC standard.

Ex: Designates explosion proof material and indicates that the apparatus has been

approved in accordance with a certificate issued.

i: “Intrinsic safety” is a protection ensuring that the energy in the electric circuit is too small to

ignite the explosive atmosphere. There are two categories of intrinsic safety: “ia” and “ib”.

ia: In intrinsic safety category “ia”, the circuit must remain safe, even in the event of two

simultaneous errors occurring that are independent of one another.

ib: In intrinsic safety category “ib” the circuit must remain safe if an error occurs.

ll: Designates that the apparatus may be used in all areas (Except mining).
