BAMO Mesures SAS designed the resistivity metre 319 ML / DB for process control and survey of demineralised water through two bottles of resins.
Input 1: controls the first bottle, as a blind instrument (without display). As soon as the fluid resistivity is less than the preset value the relay 1 switches on a signal alarm to inform the operator.
Input 2: controls the second bottle with its own alarm parameters. The measurement of resistivity is permanently displayed.
3 relay outputs are to be used either for the input 1 or input 2; adjustments are done by the operator.
The 4-20 mA outputs allow the report of process operations, in order to have a true image of water quality.
