Select empty pipe cut-off
Empty pipe cut-off is OFF
Ensure that the measuring pipe is full
Electrode connection missing/
electrode cable is insufficiently
screened
Ensure that electrode cable is connec‐
ted and sufficiently screened
Unstable flow signal
Unstable
1. Pulsating flow
Increase time constant
2. Conductivity of medium too
low
Use special electrode cable
3. Electrical noise potential be‐
tween medium and sensor
Ensure sufficient potential equalization
4. Air bubbles in medium
Ensure medium does not contain air
bubbles
5. High concentration of parti‐
cles or fibres
Increase time constant
