5.9.1 Log Format
Maintenance logs can be generated in one of two formats: Microsoft® Excel® and Comma-
Separated Values.
Microsoft® Excel
This is the recommend format for Maintenance logs in order to get the full benefits of this utility.
This option however is only available if you have Microsoft® Excel® 2000 or later installed on
your PC. The Excel® file generated by this utility has up to five worksheets as follows:
Charts - Contains charts of the data collected and stored on the Raw Data worksheet. This
worksheet is laid out to print two sheet per page on a standard 8 ½ x 11 sheet of paper.
Inspection Report -The inspection report is a one page summary of the configuration and
status of the meter. The report contains site information, meter configuration
information, alarms, and meter status. Click here for information on customizing this
worksheet.
SOS Sheet - (Available in Deluxe Edition of Daniel MeterLink Only) If a Computed SOS
value was entered, it will be included on this sheet.
Config - Contains the meter’s configuration. This configuration is called an extended
configuration because is contains registers that are read-only and are not viewable in the
Edit/Compare Configuration tool. These are registers used in the other worksheets of the
Maintenance logs.
Raw Data - Contains all of the data collected from the meter. Each row is a record polled
from the meter. Each record contains a date and time stamp based on the meter’s time
when the record was completely received. Each column of data following the date and
time stamps is a data point collected from the meter. Below all of the polled records are
rows that analyze the data and detail the minimum, maximum, average, the difference
from minimum to average, and the difference from maximum to average for each column
of data. The cells for
SystemStatus and StatA through StatD will contain a comment that
can be displayed by moving the mouse cursor over the marker in the upper-right corner of
the cell. The marker is only present if the cell is indicating an alarm (i.e. non 0x0000 value).
When using the Microsoft® Excel® log format, the following options are available:
SOS to use for comparison - To include a comparison of the meter’s measured SOS
to a calculated SOS, select one of the following methods for entering this data.
Manually entered SOS - Allows you to enter a speed of sound calculated from a 3rd
party package. This option is always available. After the Maintenance Log is
complete a dialog will be displayed in which you will enter a speed of sound to
compare against the meter. This data will be saved in the Maintenance log.
None - No speed of sound comparison will be performed or included in the
Maintenance log.
Default view -The Technician view displays the following data:
Meter Volumes, Temperature, Pressure, System Status, Flow Velocities,
Sound Velocities, Chord Statuses, Performance, Gains, Validity alarms, Flow
direction.
