Sensor cables and
conductivity of medium
Conductivity of Compact installation:
medium Liquids with an electrical conductivity ≥ 5 µS/cm.
For a conductivity between 5 and 10 µS/cm, the repeatability may degrade to
±0.5% of actual flow.
Remote
installation:
Standard cable
Note
For detection of empty sensor the min. conductivity must always be
≥ 20 µS/cm and the max. length
of electrode cable when remote mounted is 50 metres. Special cable must be used.
For remote mounting in Ex applications special cable cannot be used, empty sensor cannot be
detected and the electrically conductivity must be
≥ 30 µS/cm.
For remote mounted CT installations the max. cable length is 200 metres.
