1INTRODUCTION
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.
The electronic converter 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.
V = B·v·d
Where:
V = Measured voltage in the electrodes
B = Magnetic field
v = Liquid velocity
d = Distance between electrodes

4.1 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):
2 RECEPTION
The FLOMAT electromagnetic flowmeters with XL1 converter 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 for each
sensor.
2.1 Unpacking
Unpack the instrument carefully, removing any remains of the packing.
2.2 Storage temperatures
-20ºC ...... +60ºC
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.
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.

4.2 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.
Downstream, the minimum recommended distance to a disturbing element is 5 x DN.
4.1.1 Mixtures
If liquids of different conductivities are mixed it is necessary to install the sensor a minimum
of 50 x DN from the point of mixture in order to obtain a uniform conductivity of the liquid
and stabilize the readings.
If this distance is shorter, readings may be unstable.
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.
9
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.
4.4 Pumps
Pumps should be mounted upstream from the sensor to avoid the suction of the pump
(vacuum).
10
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.
4.8 Temperature
In open air installations it is recommended to install a protection to avoid direct sun light on
the flowmeter.
4.7 Magnetic fields
Strong magnetic fields close to the sensor should be avoided.
