Daily log
The Daniel 3410 Series Gas Ultrasonic Flow Meter stores a daily log record once per day at the
specified contract hour. (Refer to the Daniel MeterLink Help files for information on specifying
the
ContractHour
data point.)
The meter can store up to 365 daily records. The user can select whether old, unread records
can be overwritten by new records when the log becomes full via the data point
DoOverwriteUn-
readDailyLog
. 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
IsDailyLogFull
indicates whether or not the daily log is
full and cannot overwrite old, unread records.
The data points included in the daily 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 (see
the help topic for any data point in Daniel MeterLink. Click
Help|Gas 3410 Series Registers
Reference,
select the
Index
tab, start typing the data point name until the desired point is
highlighted, and then click the

button.)
