Delay time outside
the limit
Cause:
The measured error of the decay time constant is
outside the range defined in the WARNING (7546)
function.
Remedy:
Remove the sensor from the pipe and check
whether the inside wall of the measuring tube has
to be cleaned.

Coating detection
not possible
Cause:
Coating detection not possible:
1. The recovery time entered for this is too small.
2. The measuring tube is empty or not filled
completely.
Remedy:
1. Increase the value for the recovery time (
RECOVERY TIME function, 7523).
2. Fill the measuring tube (if necessary, check the
process conditions of the facility).

Remedy:
Check the application for process change (pressure,
air bubbles, inhomogenity etc.).
