Hourly log
The Daniel 3410 Series Gas Ultrasonic Flow Meter meter stores an hourly log record once
per hour on the hour. The meter can store up to 2400 hourly records (100 days' worth).
The user can select whether old, unread records can be overwritten by new records when
the log becomes full via the data point DoOverwriteUnreadHourlyLog.
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
IsHourlyLogFull indicates whether or not the hourly log is full and cannot overwrite old,
unread records.
The data points included in the hourly log and the corresponding log action are as shown
in the table below. Data points required by the API Chapter 21 standard are marked with
an asterisk (*). For information on a particular data point, consult Daniel MeterLink online
help.
