speed system with quartz
sensors that needed to be
operated, then the
manufacturer could send a
technician to the site to train
the operators. However, it is
becoming increasingly common
for weighing to be accompanied
by cameras; while measuring
and classification sensors are
used to automate the weighing
process – including the traffic
signals and information panels
that are involved. It is also
becoming more common for
data control and software to be
customized and many of these
subsystems are totally unrelated
to the products developed by
the weighing technology
manufacturer. Therefore,
the integrator is in a better
position than the manufacturer
to liaise training services for
all of the technologies in the
weighing system.
Finally, integrators are able
to arrange after-sales
warranties and maintenance
for all hardware and software
elements of the complete
weighing system.
When purchasing and
installing a complete weighing
system, customers should
consider having integrators as
a point of reference, because
relying solely on each
manufacturer does not
guarantee that the project will
run and end successfully.
Designing such a layout would
be far beyond the typical
capabilities of an electronics or
sensor manufacturer.
Another fundamental aspect
of the integrator is their support
in the validation of the site
and the associated roadworks.
This includes the geometrical
conditions of the weighing lane,
its conservation state over time,
or the state of the road
markings that determine the
boundaries of a lane in highspeed
weighing. If it is not clear
where the tolling lane is,
vehicles may accidentally drive
slightly into neighboring lanes
and this could distort the
results of the weighing process.
The ASTM 1318-09 and COST
During the start-up of a
weighing site, a substantial
amount of local constraints
must be considered in real time,
such as different vehicle types
and varying behaviors of
drivers. Theoretically, the
installation outcome should be
the same for any location, but
customization can affect the
outcomes. Unlike
manufacturers, the integrator is
able to customize each site
installation case.
Regarding software,
manufacturers are unable to
develop custom-made solutions
for each project, because the
cost would be too high. At best,
some may be able to develop
platforms that allow
multiformat data to be exported.
It is integrators who have the
capability of adapting each site
environment with customized
developments that are versatile
and unique to each project.
The penultimate step in a
project of this type delivering
training for operators and
maintenance technicians. For
example, if it was solely the
operation of a scale or a high-

Installation and operation
In many cases, integrators are
interested in helping the client
to validate their sites. They may
also be involved in supervising
workzones during the
installation of low- and
medium-speed scales to ensure
that the site is levelled correctly.
In all site cases – for high-,
medium- or low-speeds, the
integrator may be able to assist
with the auxiliary works – such
as ducts, manholes and bases –
that the client undertakes to
service their weighing systems.
Correct coordination between
all parties involved in the
installation process can help to
avoid problems that could
otherwise have been prevented.
