AMI Deltacon DG Safety Instructions 1.3. Restriction for use The AMI Deltacon DG is designed for determination of: specific (total) conductivity cation (acid) conductivity after the cation exchanger degassed conductivity after a sample reboiler in water-steam- cycles only.
Product Description 2.1. Description of the System Application The AMI Deltacon DG is a complete monitoring system for the au- tomatic, continuous measurement of the conductivity before (spe- Range cific conductivity) and after a cation exchanger (cationic or acid conductivity) and the conductivity of the re-boiled sample (de- gassed conductivity).

AMI Deltacon DG Product Description Alarm Relay One potential free contact. Alternatively: Open during normal operation, closed on error and loss of power. Closed during normal operation, open on error and loss of power. Summary alarm indication for programmable alarm values and in- strument faults.
Page 12
AMI Deltacon DG Product Description Degassed After the heat exchanger the sample is heated up to 0.5 °C below the boiling point. Hereby volatile components are removed from the Conductivity: sample, mainly carbon dioxide. Thus, the degassed cation conduc- tivity is a measure of the impurities without a CO2 error.
