1 Routine Maintenance
1.1 Meter maintenance
This section includes discussion of the maintenance of Rosemount 3814 Liquid
Ultrasonic Flow Meters.
For reference, you may download the MeterLink Quick Start Manual from:
www.emerson.com/meterlink
CAUTION
SURFACE TEMPERATURE HAZARD
Meter body and piping may be extremely hot or cold.
Wear appropriate personal protective equipment when coming in contact with
the meter.
Failure to comply may result in injury.
CAUTION
TRANSPORTATION HAZARD
When moving the meter, do not insert the forks of a forklift into the bore.
Inserting the forks may cause the meter to become unstable, resulting in injury to
personnel or damage to the bore and sealing face.
NOTICE
Prior to lifting the unit, refer to the flow meter nameplate or outline dimensional
(general arrangement) drawing for the assembled weight.
CAUTION
TRIPPING HAZARD
Clear all obstacles or obstructions from the work area when transporting,
installing or removing the meter.
Failure to comply may cause injury to personnel.

WARNING
CRUSHING HAZARD
Do not remove flange stabilizers.
Attempting to do so may allow the meter to roll, resulting in serious injury or
equipment damage.
Figure 1-1: Flange stabilizers
A. Flange stabilizers
CAUTION
ESCAPING FLUIDS HAZARD
The purchaser of the meter is responsible for the selection of Emerson
components/seals and materials compatible with the chemical properties of the
measurement fluid.
Failure to select suitable meter components/seals may cause escaping fluids,
resulting in injury to personnel or equipment damage.
1.2 Field hydrostatic pressure testing
procedures
The Rosemount 3814 Liquid Ultrasonic Flow Meter can be hydro-tested without
any special preparations. The transducers are not exposed to the process
pressure and can remain installed in the meter.
Routine Maintenance Maintenance and Troubleshooting Manual
January2023 00809-0100-3814

The liquid ultrasonic meter pressure containing parts include but are not limited
to the transducer housings. These pressure containing parts are pressure tested
while attached to the meter body as a completed ultrasonic meter assembly. The
hydrostatic test is verification of the pressure containing capability of the liquid
ultrasonic meter pressure containing parts and the seals that seal them.
CAUTION
LEAKAGE OR PRESSURE CONTAINING PARTS FAILURE
Use precautions to eliminate hazards to personnel in the event of leakage or
failure of the liquid ultrasonic meter pressure containing parts or failure of the
test equipment and to prevent over-pressurization during the test procedure.
Failure to comply may result in injury to personnel or cause damage to the
equipment.
1.3 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.
1.3.1 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. 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
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, or over time.
Looking at a single inspection report, that is either collected monthly or quarterly,
can give you an indication of the meter's 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 MeterLink which allows all important parameters to be trended.
MeterLink supports trending files in a Microsoft® Excel® workbook from multiple
3814 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 or Trend files 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. gauge 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 that 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.

log. Each of the Meter Archive logs include the Meter Configuration file.
