    AMI-II CACE Safety Instructions 1.3. Restrictions for Use The AMI-II CACE is designed for determination of:  specific (total) conductivity  cation (acid) conductivity after a cation exchanger in power and industrial plant water. It calculates the pH value and the concentration of an alkaline substance (NH , morpholine, etc.) if present in the water.

  • Page 10: Product Description

    Product Description 2.1. Description of the System Application The AMI-II CACE is a complete monitoring system for the automatic, continuous measurement of the conductivity before (specific conduc- range tivity) and after a cation exchanger (cationic or acid conductivity). Based on difference conductivity measurement, the pH of the sam- ple can be calculated.

Summary alarm indication for programmable alarm values and instrument faults.  Normally open contact: Closed during normal operation, open on error and loss of power.
  • Page 12 AMI-II CACE Product Description Fluidics The sample flows via sample inlet [M] into the flow cell [D]. The spe- cific conductivity of the sample is measured with the first conductivity sensor [A]. A downstream capillary [G] regulates the sample flow be- fore the sample enters the sample chamber of the EDI module [H].
