1.2 Routine Maintenance
Routine maintenance operations requires adherence to all applicable regulations and laws and
safety training for personnel to perform the maintenance operations. Review your
organization’s best practices procedures before performing routine maintenance.
1.2.1 Maintenance logs and reports
To monitor the performance health of the meter, and ensure it is operating within acceptable
specifications, routine diagnostics should be performed. Collecting a maintenance log gives
you a snapshot of the current health of the meter and you can compare the inspection reports
from previously saved logs. Use the Logs/Reports menu and click Maintenance Logs and
Reports. Daniel MeterLink displays the Maintenance Logs and Reports dialog. Choose the time
duration, log format and collection rate for the output file and click the Start button. You can
open the file immediately after it is generated or view it at a later time. It is recommended that a
Maintenance log be collected after an upset in the system.
In establishing a baseline to be used for the trending of the meter diagnostics, it is very helpful if
a set of log files are collected immediately after the meter has been installed in the field.
Preferably, collect the log files at several velocities within the operating range of the meter. This
helps establish that the flow profile is relatively constant throughout the meters operating
range (except velocities below 3 ft/sec where the profile may vary).
Maintenance log collection
Figure 1-2 Maintenance log collection parameters
Routine Maintenance 3
Section 1: Routine maintenance Maintenance and Troubleshooting Manual
January 2018 3-9000-772 Rev B
Trend maintenance log collection
Merging the results of two or more Maintenance logs into a single file, allows you to build a
historical database of the meter’s performance. Trending the logs indicates changes from the
original installation of the meter over time. Looking at a single inspection report, that is either
collected monthly or quarterly, will only give you an indication of the meter's current health.
Figure 1-3 Trend log collection
This is important since many diagnostics change slowly over time. Trending the maintenance
logs helps identify these changes and makes problems much more obvious than merely viewing
a single inspection report. The Trending feature is integral to Daniel MeterLink which allows all
important parameters to be trended. Daniel MeterLink supports trending files in a Microsoft®
Excel® workbook from multiple 3818 meter maintenance logs. Some parameters like gain,
signal level, and noise level may show a shift over time which can be useful in detecting changes
in the meter and the installation.
Maintenance logs to be trended must all have matching column headings. This means the logs
must be in the same units (i.e. U.S. Customary or Metric), must have the same pressure type (i.e.
gage or absolute), and must have the same time base (1/second, 1/minute, 1/hour, 1/day). If
not, an error message will be displayed stating the column headings do not match and the file
will not be added to the Workbook to trend list.

Archive log collection
Archive logs may be collected and the options include:
• Daily log - generated every 24 hours on the Contract Hour.
• Hourly log - generated every hour at the top of the hour.
• Event log - collects the alarm and event log records.

Check the transducer wiring for this pair of transducers to make sure
connections are secure and wired correctly.
— Verify the average gain of this transducer pair is not above 90dB. The gain
value can be read in Daniel MeterLink on the Monitor (Detailed) page.
— Measure the resistance with an Ohm meter across the two transducer wires
attached to the Acquisition Module. If the value is not .09<R<1.1 Mega Ohms,
replace the transducers.
— Collect a Maintenance Log, Configuration file and Waveform stream file with
Daniel MeterLink and contact your Daniel service representative.
• When connecting directly:
— Check the cross-over cable connection (P/N 2-3-3400-079)
• When Using a Hub:
— Use straight-through patch cable between the meter and the hub and a
straight-through patch cable between the hub and the PC
— Do not connect either the meter or PC to the hub UPLINK port.
— Check the CPU Module LED 1 is on (either solid red or flashing green). If the
LED is not on, check power to the meter.
— If the LED is on, check the Ethernet cable connections

Communication issues due to
blocked network ports
• Blocked network ports on the computer running Daniel MeterLink or on a company
LAN can prevent connections to the meter or prevent certain features from
working. These issues may occur over Ethernet, Modem and Direct serial connections. Reference the list of network ports used by Daniel MeterLink in the Help file
and the symptoms of having blocked ports. Contact your IT department for
assistance in resolving these issues.
• Error condition of a blocked network:
— Cannot connect to a meter
— Cannot collect Archive log files
— Cannot view or stream waveforms in Waveform Viewer or Signal Analyzer.
— Cannot upgrade firmware.
— Communications lost over serial or modem connections while
Daniel MeterLink is idle on a screen.
• Symptoms of blocked network:
— If a PING is blocked on this network port, serial or modem connections could
be lost after approximately 15 seconds of inactivity. This issue can be
confirmed by checking the log_meter log file in the Temp data folder. The
path of the Temp data folder is shown in the Daniel MeterLink About dialog.
— A blocked FTP port will generally not prevent a connection to the meter, but
will prevent log collections and program downloads. A blocked FTP port could
prevent a connection in the event the meter is running a newer version of
firmware for which Daniel MeterLink does not currently have a database configuration file. If this is a case, a message stating “Error reading database
config file dbconfig<databaseversion>.xml from the meter.” will be displayed.
Contact Daniel Measurement Services to obtain the database file and assistance in installing the file.

If you are using Windows® XP, Windows® Vista or Windows® 7 make sure that you do not have
more than one modem driver installed to the same COM port. Typically this will only be
necessary if you use one COM port to talk direct (serial communications) and use the same COM
port to connect to an external modem. This is an apparent limitation in Microsoft’s® Dial-up
Networking. If more than one modem driver is installed for a particular COM port, Dial-up
Networking will always use the last driver installed regardless of what is selected. The only work
around is to only install one modem driver per COM port on the PC at a time. Refer to the Daniel

printer driver information and Daniel MeterLink cannot use Excel® to generate reports or logs.
One solution is to install a local printer on your machine tied to LPT1. The local printer driver you
installed can be for any printer and the printer does not actually have to exist or be connected to
the PC. If you install a local printer, you can configure Daniel MeterLink to temporarily change
your Windows® default printer over to this local printer while running Daniel MeterLink. Do this
by selecting this local printer for the Override system default printer selection in the Program
Settings dialog. Daniel MeterLink will automatically change the Windows® default printer to the
selected override printer when it starts and will set the Windows® default printer back to its
original printer when it closes.
