•
Flow velocity
•
Check the flow direction. If reverse
flow is detected, check for valve leaks.
•
If the meter run typically has reverse
flow when flow is stopped, reconfig-
ure the ReverseFlowVolLmt to allow a
higher volume from the Field Setup
Wizard> General Page.

•
Speed of Sound
•
Compare Speed of Sound deviation
from measured SOS relative to the
average SOS.
•
Check the chord’s SOS.
•
Check and correct geometry configu-
ration (pipe diameter, distance
between the transducers (LA), and
delay time).
•
If present, resolve transducer issues
(failed transducer, cabling or debris
buildup on the transducer face, or
path length configured incorrectly).
•
If SOS is out of range and all checks
were positive, adjust SSMin or SSMax
(consult with a Daniel Service repre-
sentative before making these adjust-
ments).
