Audit log
The Daniel 3410 Gas Ultrasonic Flow Meters stores an audit log record whenever any
parameter affecting the flow measurement is modified. The audit log record indicates
which data point changed, the date and time of the change, and both the 'as-found' and
'as-left' values.
The meter can store up to 3000 audit records. The user can select whether old, unread
records can be overwritten by new records when the log becomes full via the data point
DoOverwriteUnreadAuditLog. This point can be modified using the Daniel MeterLink
Tools|Edit/Compare Configuration screen. The default is to overwrite old, unread records.
Refer to for information on reading records and marking records as read. The data point
IsAuditLogFull indicates whether or not the audit log is full and cannot overwrite old,
unread records.
The data points monitored and collected for the audit log are as shown in through below.
The points are grouped and, within each group, are listed alphabetically.
The groupings are as follows:
• AGA8
• AGA10
