3.2.2 The daily records
The daily records are used to log the daily records, also known as contract hours (user
defined).
Each daily record has:
•
a sequence number;
•
a date/time stamp;
•
the flowrate;
•
the total;
•
the accumulated total.
3.2.3 The event records
The event records are used to log the B3100 related events. These events have a
manufacturer defined content.
Each event record has:
•
a sequence number;
•
a date/time stamp;
•
(as applicable) an event type number;
•
(as applicable) an event content description.
The event records are used to log events that happen during operation. The logging is done
at the moment an event happens.
4 Operation
The data log function records the performance of the B3100 and the measured medium that
passed the sensor (e.g. flowmeter) with respect to the time and the date. The interval and
daily records are logged as programmed in the setup menu DATALOG.
4.1.1 The interval log
This log is made to record the data once at every user defined moment in time.
The B3100 makes one record, as a snapshot, per programmed interval. When the
maximum amount of records is made, the eldest record is overwritten by the newest record.
4.1.2 The daily log
This log is used to record the data at a pre-determined time in the day, e.g. before or at the
end of a so called contract hour. This function is meant to determine, by hand, the total of
the previous contract hour or to trend the total over a certain period of time. When the
maximum amount of records is made, the eldest record is overwritten by the newest record.
