Information!
Only if the meter pipe is completely filled will
a correct measurement be made. The func-
tion "Detector empty pipe" can be used to
continuously monitor this condition. If the
fluid level drops below the electrode level,
then all outputs can be automatically set to
zero. Thereby erroneous pulses and indica-
tions can be avoided when the meter pipe is
empty. When the meter pipe is full, the error
message „empty pipe“ is turned off and the
systems returns to normal operation.
