Electromagnetic Flow Meter

Operating Principles

The electromagnetic flow meter is an instrument for measuring the flow
of conductive fluid using Faraday's electromagnetic induction law, and
consequently the fluid must be electrically conductive.

As illustrated below a magnetic field with density B - perpendicular to the
direction of flow - stretches across a fluid flowing within an electrically
isolated pipe.

The magnetic flux will induce a voltage difference (E) that can be measured
between two electrodes arranged perpendicular to the direction of flow
and the magnetic field. The voltage is proportional to the velocity (V) of the
fluid.

➀ E = B x D x V x k [Volt] where
E is the voltage that is induced between the two electrodes
B is the magnetic flux density
D is the distance between the two electrodes
V is the fluid velocity
k is a dimensionless constant
The flow of the fluid Q (m3/s) is given by the following formula:

➁ Q = π x D2 x V / 4 => V = 4 / (π x D2) where

π : is the constant pi (= 22/7)
D: is the internal diameter
V: is the fluid velocity
The combination of above formulas ➀ and ➁ gives the following formula:

E = K x B x D x Q x 4 / (π x D x D) = 4 K x B x Q / (π x D)

The MagFlux® Flow Meter

Measurement

Electromagnetic flow meters may have either direct current (DC) or alter­nating current (AC) excitation.

When systems are AC excited, electrostatic and/or electromagnetic noise
may influence the measurements. A DC excited system however, is less
sensitive to noise produced by electromagnetic induction, simply be­cause the voltage induced over the electrodes will be a DC voltage. The
drawbacks are measurement errors due to electro-chemical polarization
between the electrodes and the fluid.

The MagFlux® electromagnetic flow meters are excited by a 2.5 Hz
square wave and thereby eliminate the drawbacks of both DC and AC
systems.

A microprocessor receives and measures the amplitude of the pulse with a
16-bit resolution, and converts and displays the result on the display unit.

Electrode Cleaning

Electrode cleaning is always in service to maintain clean and accurate
electrodes. The operating principle is a 55 Hz AC voltage superimposed
on the normal 2.5 Hz square wave. This step effectively reduces the risk
of a dirt layer build-up on the electrodes that eventually will deteriorate and
finally isolate electrical contact to the flow media.

Product Identification

A delivery will usually consist of a MagFlux® converter and a MagFlux®
flow sensor. Check that the item(s) delivered corresponds to the ordered
item(s). The part number and the calibration code are printed on an iden­tification label sticked onto the flow converter shipping box and on a label
on the flow converter itself. The part number, the serial number, the cali­bration code and the electrode/lining data for the flow sensor are printed
on a green name plate (see example below).

This calibration code (Cal. code) is unique and provides the MagFlux®
converter with information about flow sensor number, nominal diameter of
the flow sensor and calibration data for the flow sensor.

The current converter firmware requires an 8-character input, but it also
accepts 6 characters plus two "Ok"s. The example above (dw5uq4) would
require that you enter: d w 5 u q 4 "Ok" "Ok", where "Ok" indicates that
you press the "Ok" key without selecting any character. Only small letters
can be entered from the MagFlux® keypad.

If changes are needed to the unique sensor calibration code following
initial setup, this is the calibration code that the "Sensor Calibration Code"
menu must contain (see pages 44 and 86).

3. Flow Sensor

The following conditions must be satisfied to get the full benefit of the

MagFlux® flow sensor.

Minimum conductivity

• The conductivity of the media must be greater than 5 µS/cm.

Liner selection

• Use Teflon® lining for chemicals and food industries

• Use hard rubber lining for drinking water and waste water

• Use soft rubber lining for water with abrasive particles

Electrode selection

• Steel AISI 316TI-1.4571 for general purpose, sewage, water and district
heating systems

• Hastelloy for sea water

• Titanium and platinum for chlorine and other aggressive chemicals

Mounting location

• To obtain a stable and accurate flow measurement, it is very important
that the flow sensor is mounted correctly in the pipe system

• There must be no flow fluctuations

• Avoid locations where vacuum can occur; especially for flow sensors
with Teflon™ linings

• Avoid locations with vibrations from for example pumps

• Avoid locations with extensive temperature changes

• Avoid corrosive environments and locations with a great risk of con­densation, or consult factory for special builds for these locations

• Take care that condensate and water cannot enter the connector box
on the flow sensor.

• There must be sufficient free space around the flow sensor.

• IMPORTANT: Observe that the correct flow direction is set in the

MagFlux

flow direction is "A" (flow direction towards left).

The flow directions A or B are clearly shown on the name plate. Default
flow direction is "A".

Pressure loss

The pressure loss can easily be determined, if the nominal pipe diameter is
greater than the MagFlux® flow sensor. See the diagram below:

Pressure loss graph

0.003

The diagram illustrates that decreasing the internal diameter from 100 mm
(DN) to 80 mm (DO) will cause a pressure loss of 0.003 Bar @3 m/s.

Pipe System

1. The flow sensor must be mounted in a location which is free from inter­fering elements like valves, Ts, bends, pumps, etc. to ensure a laminar
flow without turbulence upstream of the flow sensor. For that reason
the flow sensor must be mounted in a straight pipe at a distance from
interfering elements of minimum 3 x DN upstream and minimum 2 x
DN downstream.

Flow direction

Flow direction

Flow direction

Important: Valves should always be mounted on the downstream side

of the flow sensor!

19

FW: 842018/842009

Electromagnetic Flow Meter

2. If it becomes necessary to use reducers, the inner angle must not

exceed 7.5°.

The minimum length to keep the angle below 7.5° can be checked by

means of the formula below:

L = (D - d) x 7.63

where "D" is the large diameter and "d" the small diameter of the re-

ducer.

Example: If a flow sensor in dimension DN 80 is mounted downstream

of a 100 mm pipe, the reducer must then have a length of minimum
152,6 mm in order to keep the inner angle below 7,5 °.

3. Flange connections must be assembled concentrically on both the up-

stream and the downstream side. Measuring accuracy will be affected
by turbulence in the liquid from poorly made connections.

Important: Gaskets and grounding rings must also be mounted con-

centrically!

4. The flow sensor should always be filled with liquid. For that reason the

flow sensor must not be mounted at the highest point of the pipe sys­tem or in free outlets, where gravity could empty or partially empty the
pipe.

20EN 3.05 MagFlux Manual 1212

Electromagnetic Flow Meter

5. The flow sensor can be mounted vertically or horizontally.

If the flow sensor is mounted vertically, the flow direction should always

be upwards. In that way the effect from possible bubbles in the liquid
will be significantly reduced, just as it will ensure that the flow sensor is
always filled with liquid.

In case the liquid is carrying particles, for example when measuring

sludge, sewage, etc., the flow sensor must be mounted vertically.

6. When mounting horizontally in pipes with free downstream outlet, the
flow sensor should be mounted such that it will always be filled with liq­uid, for example in a bend situated lower than the height of the outlet.

In case the liquid is carrying particles, e.g. when measuring sludge,

sewage etc. the flow sensor must be mounted vertically.

21

FW: 842018/842009

Electromagnetic Flow Meter

7. When mounting horizontally the flow sensor can be rotated max. +/- 45°

seen from the connection end. If the flow sensor is rotated more than
45°, one of the electrodes may not be in full contact with the liquid.

Cabinet Mounted on the Flow Sensor

The cabinet is mounted on the flow sensor with four pcs. 6x12 hex cap
screws.

6. Startup

Initial Checks

Before switching on power the following steps must be checked.

1. The local mains power supply voltage corresponds to the voltage
printed on the identification label of the flow converter.

2. All electrical connections are made in accordance with the electrical
connection diagram shown on page 32.

3. All terminal screws are tightened.

4. All cable glands are tightly secured.

5. All grounding connections are made in accordance with the instruc­tions in this manual (see page 23).

Initial Flow Measurement

1. Make sure that the flow sensor is completely filled with liquid.

2. Turn on power to the flow converter and wait one minute.

3. Verify or enter the calibration code of the flow sensor in the
"Converter Setup/Service Menu/Sensor Calibration Code" menu (see
also page 86).

If the entered calibration code is incorrect, and for example indicates a

wrong internal diameter, read the correct calibration code on the con­verter as explained on page 14.

Flow Direction Check

1. Allow free flow through the sensor.

2. Check on the display unit screen that the flow value increases. If the
value goes negative, check that the "Flow direction" option is set cor­rectly and/or check the electrical connections on the flow sensor.

Language Selection

1. The default display language is English. If another language is required,
proceed with step 2.

2. Select "Display Setup" from the Main Menu.

3. Select "Language" from the Display Setup menu and chose the re­quired language (see page 96).

Display Read-out, one connected unit

All MagFlux® display read-outs are illustrated and described in this manual.
Chapter 6. MagFlux Menus (on page 47) gives a detailed description of the

displays shown during setup, configuration and normal operation.
A 5-line LCD screen displays symbols and the actual status during setup,

configuration, servicing and normal operation (see also page 48).

each unit have been assigned a unique name and Modbus ID num­ber. See page 98 for details.

Display Keys

The keys and the soft keys (variable key functions determined by the
display firmware) are used for initial programming and normal operation of
the flow meter.

The function(s) of the four available keys is displayed at the bottom of the
display. The symbols and actual functions are described in detail in the

Contrast Adjustment

Adjust the display contrast by pressing the two outmost keys simultane­ously (indicated by the keys) and press the up/down keys as required.

Save the new setting by pressing the two outmost keys simultaneously.

System Reset

You can reset and refresh all system displays and key combinations by
pressing all four keys simultaneously.

This feature is especially useful during for example a service call, where
the display language (Dutch, Danish, etc.) cannot be understood by the
service person. A system reset immediately sets the display language to
(GB) English.

The system reset must not be confused with the ultimate "Recover factory
settings" (see page 100) which deletes all local configurations/settings and
replaces them with default factory settings.

Initial Setup

Initial setup is normally performed by MJK personnel and is required to get
started with the MagFlux® flow meter.

A unique sensor calibration code provides the MagFlux® flow converter
with information about flow sensor number, nominal diameter and calibra­tion data.

If changes to the unique sensor calibration code are needed following
physical installation and initial setup, the "Sensor Calibration Code" menu
must be addressed.
A password is not required to enter or change the sensor calibration code.
Toggle through the displayed digits with the right-arrow key when prompt­ed for a password and press OK.

Electromagnetic Flow Meter

The data log contains:

• Date

• Time

• Flow values

In case of a power failure, the data logger continues when power returns.
If more converters are connected to one Display Unit, each converter has

its own individual log interval and can be sorted.
All converters share the same memory of 160.000 entry points.
The log data can be shown on the Display Unit or be stored in an external

CSV file. MJK-Field Link software is needed for transfer of data into CSV
file format via the USB port in the display unit. The format can be read in
for example Microsoft

An example of the log capacity of one sensor versus the time interval is
shown in the following table.

mA Output

When a MagFlux® is connected to a power supply for the first time, the
mA output is automatically set to provide 4 mA at zero flow and 20 mA at
a flow corresponding to the theoretical Qmax of the flow sensor.

Changes in the mA setting will not affect the relay output settings.
Note: Both values can be set in the range 10 % to 120 %, making it

possible to increase or decrease the mA signal.

The "mA Output" parameters can be configured in four different ways.
Each option is described in the following sections.

Using the factory setup MagFlux® returns to default mA settings corre­sponding to the chosen MagFlux® flow sensors Qmin and Qmax.

The mA output is an active output, and the maximum load is 800 Ohm.
The upper limit for the mA output is 20,5 mA

3,75 mA indicates the mA output is not in use
3,5 mA indicates flow under 4 mA level
20,5 mA indicates flow higher than 20 mA level.

The 20 mA maximum output is rounded up to the nearest round figure.

Example: The maximum flow of 17.676 m3/h for a DN25 is rounded
up to 20.000 m3/h.

Flow Forward

The mA signal provides 4 mA at zero flow and 20 mA at Qmax in the for­ward direction.

Electromagnetic Flow Meter

If a required volume betwen pulses is not contained in the above steps,
for example for a pre-set to a sampler, use the batch counter option.

The relays are limited to a minimum and a maximum of pulses pr. hour
depending on the 20 mA scale and the on-time of the relay in milli­seconds.

DO 1 (Opto Relay)

The maximum limit is 500 pulses pr sec at 1 ms pulse length.

The formula for the minimum flow unit pr pulses is:
(flow at 20mA) x (pulse delay in mSec) / 1800000

Example: Min. flow unit/pulses for DN 100 max. flow 300 m3/h ?

3

Minimum flow unit pr pulses = 300 m
0,016 m3 which is rounded to 0,1 m3 by the MagFlux.

The formula for the maximum flow unit pr pulses is:
(flow at 20mA)

Example: DN 100 max. flow 300 m

Maximum flow unit pr pulses = 300 m

x 100 mSec / 1800000 =

3

/h ?

3

DO 2 (Mechanical Relay)

The maximum limit is 120 pulses pr hour.

The formula for minimum flow unit pr pulses is:
(flow at 20mA) / 120

Example: DN 100 max. flow 300 m3/h ?

Minimum flow unit pr pulses = 300 / 120 = 2,5 m3 which is rounded to
10 m3 by the MagFlux.

The formula for maximum flow unit pr pulses is:
(flow at 20mA)

Example: DN 100 max. flow 300 m3/h ?

Limitation of the automatic batch counter on DO 1 (Opto Relay)

The maximum limit is 500 pulses pr sec at 1 ms pulse length.

The formula for the minimum flow unit pr pulses is:
(flow at 20mA) x (pulse delay in mSec) / 1800000

Example: Min. flow unit/pulses for DN 100 max. flow 300 m3/h ?

Minimum flow unit pr pulses = 300 m
0,016 m3 which is rounded to 0,1 m3 by the MagFlux.

The formula for the maximum flow unit pr pulses is:
(flow at 20mA)

Example: DN 100 max. flow 300 m3/h ?

Maximum flow unit pr pulses = 300 m

Limitation of the automatic batch counter on DO 2 (mech. relay)

The maximum limit is 120 pulses pr hour.

The formula for minimum flow unit pr pulses is:
(flow at 20mA) / 120

Example: DN 100 max. flow 300 m3/h ?

Minimum flow unit pr pulses = 300 / 120 = 2,5 m3

3

x 100 mSec / 1800000 =

The formula for maximum flow unit pr pulses is:
(flow at 20mA)

Example: DN 100 max. flow 300 m3/h ?

Maximum flow unit pr pulses = 300 m

Limitation of the manual and adaptive batch counter on DO 1 or DO 2

The formula for minimum flow unit pr pulses is:
(flow at 20mA) / 360

Example: DN 100 max. flow 300 m3/h ?

Minimum flow unit pr pulses = 300 / 360 = 0,833 m3

24h Flow

The "24h Flow" option measures the total flow (FTot) for 1 day (24 hours)
and logs at midnight (12 PM). Contact MJK for detailed information.

Valid settings are "No" and "Yes" (default is "No").

Status

The "Status" option provides an overview of the in- and output status. The
check boxes can contain four different characters to indicate the current
status at that very moment:

X A cross (X) in a check box indicates an active state
/ A blinking forward slant (/) in a check box indicates that the input/

output is in the process of being activated. Eventually it turns into a
steady X.

\ A blinking backward slant (\) in a check box indicates that the

input/output is in the process of being de-activated. Eventually the
check box is cleared.

An empty check box indicates a de-activated state.

Sensor Calibration Code

Each and every MagFlux

®

has a unique calibration code that contains
calibration data for the specific unit. A calibration code could for exam­ple be dw5uq4 or 7v3ri0.

The current converter firmware requires an 8-character input, but it also
accepts 6 characters plus two "Ok"s. If the code is dw5uq4, enter:

d w 5 u q 4 "Ok" "Ok"

where "Ok" indicates that you press the "Ok" key without selecting any
character. Only small letters can be entered from the MagFlux® key­pad.

IMPORTANT: All letters are small letters (e.g. “a” and not “A”), and
numbers are big characters (e.g. “0”, zero and not “o”, small o).

A potential source of error is incorrect reading of numbers and letters,
where a small “o” is confused with a zero (“0”), or a small “l” is con­fused with the number one (“1”).

Note also that the default flow direction from factory is “A”.
