Brief description
With the LIMES analyser, RLS Wacon offers a compact and very easy-to-use analyser for the
automatic online monitoring of water treatment plants.
The measuring device works on the principle of "limit value monitoring with colour change" and
provides all important functionalities for reliable field use.
The LIMES analyser automatically carries out water analyses at regular intervals to determine the
total hardness.
Based on the reagent type used, a limit value is specified by the user. There are 4 reagents
available for monitoring the total hardness.
If the limit value is exceeded, the unit outputs a message on a potential-free relay output. This
message can be further processed by a softening control. In this way, functions such as
automatic regeneration triggering can be realised.
The LIMES analyser is characterised by low maintenance costs. Up to 10,000 analyses can be
carried out with a 750 ml reagent bottle. The input contact of the device can additionally be
used to connect a flow monitor to the device. In this way, the LIMES interrupts the analysis
interval during downtimes of the water softener and automatically resumes the analysis when
the unit is put back into operation.
To prevent disturbances due to the counter ion effect, a first value suppression is available. If the
limit value is exceeded, this first carries out another control measurement before a hard water
message is issued.
You will find in-depth and much more information about your new LIMES analyser in this
manual.
