5.1.5 Audit log report
The Daniel 3810 Series Liquid Ultrasonic Flow Meter stores an audit log record whenever
any parameter affecting the liquid 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
Section 5.2.5 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 for the audit log are as shown in (Table 5-2). The points are
grouped and, within each group, are listed alphabetically. The groupings are as follows:
• Calibration
• Chord Proportions
• Co-located meter
• Communications
• Data Logging
• Expansion Correction
• Flow analysis
• Frequency, Digital, and Analog Signals
• General
• HART
• Indicators
• Local display
• Meter Information
• Pressure and Temperature
• Reynolds Number Calculation
• Signal Processing
• Tracking
