750 ml indicator bottle. The input contact of the device can also be used to connect a flow monitor to the device. This means that the LIMES interrupts the analysis interval when the water softener is not in use and automatically resumes the analysis when it is restarted. - Page 7 General information These operating instructions describe the installation and operation of the LIMES online analyser. Installation and commissioning may only be carried out by an authorised specialist. The appliance may only be operated under the conditions described in these operating instructions.

Page 36: Operation And Handling
The reset may only take place if you have used a full 750 ml indicator bottle. Functional principle The LIMES, based on the SYCON series, is an online analyser for the automatic determination of total hardness using the colourimetric limit value method. A colour reaction is generated by adding an indicator to the water sample. -
