Dear customer,
Thank you for purchasing this device SalinoMADD. This gauging device allows you to measure the flow of rivers
very fast and easily according to the tracer dilution method.
The SalinoMADD is shipped in a sturdy carrying case. It is strongly recommended to always replace the device,
the probe and accessories into this suitcase, which will ensure the best protection. Although it was designed
for use in difficult conditions, it is a piece of precision equipment that must be protected from impact. Handled
with a minimum of precautions, SalinoMADD will help you for long time!
In order to best use your new system, please read this manual and observe the manipulations described below.
CCoonntteenntt
Upon delivery of a device SalinoMADD, the package contains the following materiel:
• A carrying case in polypropylene with rubber-foam inserts
• A SalinoMADD measuring unit with 4 alkaline batteries 1,5V
• A probe for water salinity and temperature with 10 meters cable and connector
• A straight calibrated measure for 100ml.
• 5 doses of 20 ml calibration solution
• A CD “SalinoMADD” containing
o The software SalinoMADD
o This instruction manual
o A notice about the gauging method
o A demo video of a gauging with SalinoMADD
• A serial cable for the communication between SalinoMADD and a PC
The device is delivered ready to use and calibrated.
WWaarrrraannttyy
The device is delivered with a factory warranty for one year from the date of the invoice. Repairs are made in our
workshop; no further benefit can be taken into account without written confirmation of MADD
is understood that this warranty is available only if the device SalinoMADD was used in conditions for which it
was expected, as described below. Any other manipulation should be done at risk and peri of the user.

The device SalinoMADD uses the tracer dilution method to determine the stream flow of the measured
watercourse.
Principle
The main principle of this method consists to inject into a watercourse a concentrated solution of tracer.
Downstream, at a distance large enough from the injection point for a good mix with the river water, the tracer
concentration is measured during the passage of the tracer could. This dilution is a function of flow rate,
assumed constant along the section concerned during the measurement time.
The following conditions are necessary for the application of the dilution method:
• The flow of the river should remain roughly constant during the measurement;
• The tracer must pass totally through the gauging sector;
• At the measuring point, the mixture should be such that at each point of the section of the river must
spend the same amount of tracer.
According to the above conditions, this method is especially adapted in case of low depths, very high speed or in
presence of turbulences that does not guarantee a stable speed, like rivers or streams. As against, it is not
suitable for measuring flow in concrete channels which does not permit the mixing of the water.
Cooking salt as tracer
The cooking salt, sodium chloride (NaCl), is an ideal tracer: it is very easy to find, cheap and has a high degree of
dilution in water. Furthermore, it is not harmful to the fauna and flora at the concentrations used and it is few
absorbed by vegetation and materials of the bed of the river. Finally, it is very easy to measure its concentration
with a conductivity probe.

Replacing dry cells
The batteries are accessible on the back of the device.
Unscrew the two screws of the battery cover, remove
the old batteries and replace the 4 alkaline dry cells
respecting polarity as indicated inside the housing.
Close the lid.
A set of new cells has a voltage of 6V. This voltage is
displayed in the main menu. When this voltage downs
below 3V, it is necessary to change the batteries. The
autonomy is approximately 30 hours in normal use
with one set of alkaline manganese batteries, type.
AAA, AM3, LR6, Mignon, UM3 etc.
Power on the unit
To switch on the SalinoMADD, just press the button .
At this time the display on right for 2 seconds. It contains also the
software version, useful for eventual future updating.
Functions of the sensor touches
SalinoMADD possess four function buttons disposed on the front panel:
Switch on the unit.
Confirm the chosen parameters displayed.
Go to the next option. Increase numerical values step by step at the
programming of gauging sites.
Back to the last option. Return to the main menu.
