Cause/remedy
Cause:
The pipe transmitted wave may
superpose the signal. We
recommend you alter the sensor
configuration in the event of this
error message.
"
Caution!
A change of the sensor configura-
tion is required if the measuring
device indicates zero or low flow.
Remedy:
– In the SENSOR
CONFIGURATION function,
change the number of traverses
from 2 or 4 to 1 or 3 and mount
the sensors accordingly.
Cause:
System error
