gathered can be used for control intervention and the generation of reports on, for
example, the effects of long-term abstraction.
Both before and during raw water treatment, the instruments and systems play an
important role in helping to ensure the quality of the drinking water supply.
A wide range of standard discrete monitoring and control products are offered, many
of which are also available in System 19 rack-mounting form for compact and
economical installation.
These are ably complemented by other, more specialised equipment and systems for
both analytical and water treatment applications, to meet the exacting requirements of the
industry.
Kent Instruments and systems and water meters are widely used throughout the water
distribution network in pipelines, water towers, reservoirs and so on.
In recent years a variety of microprocessor-based and computer-compatible add-on
systems have been developed to provide hard data on leakage control, water distribution
and other useful analyses.
The System 19 instrumentation and systems can be found in all areas monitoring the
outfalls from industrial processes, in rivers and at the treatment plant itself.
