8 WATER LEVEL LIMITS
8.1 GENERAL
The water level limits consists in: n. 2 level rods, n. 2 probes, electrical cables, n. 2 electronic relays. The
device prevents the lowering of the level of water in the steam generators and the consequent overheating of
the membrature.
The principle of survey and control of the level is based on water conductivity. In order to guarantee
the correct operation of the device, following conditions must be fulfilled:
• Water conductivity > 250 µS/cm
• Water temperature < 210°C
• Pressure < 20 bar
(See. " Operating water " - Tab. 2 ).
