SENSOR FLOMAT-FX
1WORKING PRINCIPLE
The FLOMAT electromagnetic flowmeters are based on Faraday’s induction law.
When an electrically conductive liquid flows through a magnetic field, perpendicular to the
flow direction, it induces a voltage V proportional to the liquid velocity.
Two electrodes in contact with the liquid and positioned perpendicularly to the magnetic
field, sense this voltage V.
2 RECEPTION
The FLOMAT electromagnetic flowmeters are supplied conveniently packaged for
transportation together with their instruction manual for installation and operation.
All the flowmeters have been verified in our calibration rigs to obtain the gain factor Fc for
each sensor.
2.1 Unpacking
Unpack the instrument carefully, removing any remains of the packing.
2.2 Storage temperature
-20ºC ...... +60ºC
V = B·v·d
Where:
V = Measured voltage in the electrodes
B = Magnetic field
v = Liquid velocity
d = Distance between electrodes

7
4.1 Sensor position
The optimum position to install the sensor is with the electrodes in the side of the pipe. This
way, air pockets at the top of the pipe are avoided.
3 HANDLING
It should always be done with care and without knocks.
4 INSTALLATION
This should be made in a straight pipe run that guarantees that the pipe is always completely
full and where there is a fully developed turbulent flow profile (follow indications on point 4.2).
Avoid high points of the pipes where air pockets usually form, or pipes with downwards flow
where vacuums can occur.
Partially full pipes can involve important reading errors.
Flow rate measurement with open discharge makes it necessary to install the flowmeter in a
pipe section with a siphon which avoids stagnation of air in the sensor.

8
4.4 Pumps
Pumps should be mounted upstream from the sensor to avoid the suction of the pump
(vacuum).
4.2 Straight pipe sections
The point where the FLOMAT sensor will be installed must be a straight pipe section,
separated from elements that can disturb the flow profile, such as elbows, diameter
changes, etc. Depending on the element the minimum necessary distances upstream from
the sensor are shown on the next page (BS 1042-2.2:1983 standard).
Downstream, the minimum recommended distance to a disturbing element is 5 x DN.
4.3 Valves
Control valves or shut-off valves should always be installed downstream from the sensor to
assure that the pipe is always full of liquid.

4.5 Aeration
If there is a point where the difference in level is higher than 5 m an air inlet valve should be
installed after the sensor to avoid a vacuum effect that could damage the sensor.
4.6 Vibrations
Vibrations of the pipes should be avoided by anchoring the pipe before and after the sensor.
The vibration level should be less than 2.2 g in the range of 20 -150 Hz according to IEC 068
-2-34.

11
4.7 Magnetic fields
Strong magnetic fields close to the sensor should be avoided.
4.8 Temperature
In open air installations it is recommended to install a protection to avoid direct sun light on
the flowmeter.
With thermally insulated pipes DO NOT insulate the sensor. High temperatures can damage
it.
The maximum liquid temperatures are shown on page 53.

12
5 MOUNTING
5.1 Pipe adaptor mounting
The sensor is normally supplied mounted in its pipe adaptor. Before welding the adaptor to
the pipe, the sensor must be removed to avoid irreparable damage due to excessive
temperatures.
There are two basic types of pipe adaptors: with threaded or with flanged connection.
For the smallest pipe diameters (DN40, 50 & 65) the pipe adaptor is supplied welded to a
short length of pipe with a “T” form. For this type just couple it to the pipe by welding or
gluing in the case of PVC, PP, PE or other plastics.
For DN80 and bigger, there are three lengths for each of the two types of fittings.
The process of putting the pipe adaptor in should be done accurately. The distance (H) (see
drawings on next page) which is what the pipe adaptor should protrude above the surface of
the pipe is important.

13
As shown in the following table, to know the distance, the thickness of the pipe smust be
known.
In order to make the positioning of the pipe adaptor in the pipe easier, there is a label on one
of its sides with markings indicating the position of the internal pipe diameter for each DN.
Cut this label above the line corresponding to the DN of the pipe, at a distance equal to the
pipe thickness. Peel off the bottom part of the label. Once the pipe adaptor is placed into its
final position, where the label was cut must coincide with the outer diameter of the pipe.
This ensures that the measuring electrodes penetrate far enough in the area of flow profile
that will allow an accurate measurement.

Example:
Suppose a pipe of 300 mm inner diameter (DN300) and 5.5 mm thick. In the chart we can
see that the distance that the pipe adaptor must extend above the external wall is H = 60.5 -
s = 60.5 - 5.5 = 55 mm.
The values in the chart are calculated considering the gasket supplied with the instrument,
which is 3 mm thick. If the thickness of the gasket is changed, the value of H will change.
The equation to calculate H’ for a gasket of thickness d is the following:
H’ = H + 3 - d
In the previous example, if the gasket was 5 mm thick, the distance that the adaptor should
extend above the external wall would be H’ = 55 + 3 - 5 = 53 mm.
Drill a 48.5 mm diameter hole in the pipe to insert the pipe adaptor and weld the fitting to the
pipe.
If the pipe is made of concrete or other material to which the pipe adaptor cannot be
welded, a clamp-on accessory or saddle should be used. In this case, please contact us to
inform about the suitable sensor length.
The axis of the pipe adaptor should be perfectly perpendicular to the pipe axis.
5.2 Sensor mounting
Once the pipe adaptor is mounted, place the flat seal in its position and install the sensor
with the arrow pointing in the flow direction. The electrodes must be perfectly perpendicular
to the pipe axis.
In order to align the sensor, the two bolts or pins situated in each side of the cylinder in the
top of the FLOMAT sensor must be aligned with the axis of the pipe and the arrow pointing
in the flow direction.
5.3 Tightening torque
The tightening torque for the flange screws should not exceed 7.1 Nm.
The tightening torque for the threaded fitting should not exceed 21 Nm.
5.4 Electronic converter connection
See point 2.1 on page 15.
5.5 Electronic converter programming
FLOMAT sensor is insertion type, so it can be installed in pipes with different diameters.
NOTE: It is essential to program the internal diameter of the pipe, in order that the converter
can indicate the correct flow rate (see point 6.4 on page 30 or point 13.3 on page 46).

MX4 CONVERTER
1 INTRODUCTION
The MX4 converter unit can be used with the different FLOMID and FLOMAT series of
electromagnetic flow sensors. The electronic circuit is based on the most advanced
technology in digital signal processing, in order to obtain accurate and reliable
measurements.
The device provides the following features:
• Coil excitation by means of pulsed signal to obtain a negligible zero offset.
• Pulse and current output proportional to the flow rate and user programmable.
• Relay outputs user programmable as flow rate alarm or status.
• Local and remote mounting.
• Easy exchange with other sensors.
• Graphic display with intuitive menus.
• Adjustable front cover in order to make display reading easier, depending on
installation.
2 INSTALLATION
2.1 Sensor connection
2.1.1 Compact converter
The converter provides two
cables to be connected to the
sensor. Once connected, slide
the converter along the sensor
neck until the stop. Tight the
two fixing screws.

2.1.2 Remote converter
One of the ends of the cable has a header and two wires, to connect them to the sensor.
The connection is as explained in point 2.1.1.
The other end has to be connected to the converter, and has five wires. The cable must be
passed through the cable gland and the connection for each wire is explained in chapter 3.
2.2 Electrical connection
For the electrical installation, the MX4 converter has two terminal strips. To help in the wiring
of the equipment, the description of the terminals is marked on a label in the rear cover of
the device.
For the electrical installation it is recommended to use multiple conductor cables with
individual cable sections in the order of 0.25 to 0.5 mm2in order to make it easier to
connect. It is better to maintain the cables with mains voltage (power supply) separated from
the cables with low level signals (4-20 mA, etc.).
Before starting the installation, check that the cable glands are the right size for the cables to
be used. This will guarantee the instrument will stay watertight. The cable glands used are
for cables with outside diameters between 3.5 mm and 10 mm
To connect the cables, peel the outside insulation to free the inner cables. It is
recommended to put a terminal at the ends of the wires to avoid loose ends. Pass the
cables through the cable glands and screw down in the corresponding positions of the
terminal strip. Once the wiring is finished make sure that the cables are well gripped by the
cable glands to maintain the degree of protection.
Incorrect installation of the cable gland or inadequate cable placement can cause irreparable
damage to the converter.
IMPORTANT NOTE: In order to comply with the electrical safety requirements as per EN-
61010-1 (IEC 1010-1), the installation of the equipment must take into account the following:
• A mains switch must be provided to disconnect the equipment. This switch must
be marked as the disconnecting device for the equipment and be within easy reach
of the operator.
• The mains supply must have an earth line.
• The housing must not be opened when the instrument has mains supply
connected.
IMPORTANT NOTE: To ensure smooth operation of the equipment, it is recommended to
make the connection paying attention to the following points:
• For the output signals, use shielded cable when possible.
• Keep the cables away from strong sources of noise.

17
2.2.1 Power supply wiring
Before starting the installation of the equipment, check that the supply voltage available is
the same as marked on the label of the converter.
Terminal Power supply AC Power supply DC
8Earth NC
9 Neutral -
10 Phase +
It is very important to connect the mains earth to the instruments with AC power supply due
to the presence of a mains filter inside the converter that uses this connection.
2.2.2 Relay output wiring

18
Terminal Description Relay
6Normally Open Relay 1
5Common Relay 1
4Normally Open Relay 2
3Common Relay 2
The relay outputs provide relays with potential free contacts (see characteristics in page 53).
The status of the relay contacts corresponds to the relay at rest.
The relay contacts are not protected in any way, and therefore they must be installed
externally as required in the application, taking into account the limitations of the
characteristics of such contacts. In the case of having inductive loads, and to extend the
working life of the relay contacts, it is recommended to use overvoltage protection (VDR for
AC and diodes for DC loads). In all cases a fuse or some kind of protection against short
circuits, should always be provided according to the needs of the intended load.
2.2.3 Remote reset input wiring

19
Terminal
1Contact
2Contact
These terminals correspond to an input that resets the value of the totalizer. A potential free
normally open push button can be connected. The push button contact must be a good
quality snap action switch to guarantee correct working at low voltages and reduce contact
bounce effects.
2.2.4 Analog output wiring
Terminal
11 mA (positive, active output)
12 mA
13 mA (negative, passive output)
The analog output is galvanically isolated. It can be either active (which means that the
receiving device must be passive) or passive (which means that the receiver must supply the
power for the current loop). It is recommended to use a receptor with an input resistance of
less than 700 Ω to guarantee correct operation.
The configuration of the analog output mode (active or passive) is done by means of the
connection to the terminal strip. For active mode, terminals 11 and 12 are connected. For
passive mode, terminals 12 and 13 are connected.
NOTE: The analog output has protection against reversed polarity. Due to another
protection against over voltages, if a loop supply voltage of more than 32 V is connected
with reverse polarity, the converter may be damaged.

20
2.2.5 Pulse output wiring
Terminal
14 Collector
15 Emitter
The pulse output is opto-isolated. The terminals are the collector and emitter of a NPN
bipolar transistor.
In the case of using inductive loads, in order to protect the output transistor, the use of free
wheeling diodes is required.
