6.1.2 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 “Options for reading daily and/or hourly log records” 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.
