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

Rosemount 3814 Liquid Ultrasonic Flow Meter 5

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
6 Emerson.com/Rosemount

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.
Routine Maintenance Maintenance and Troubleshooting Manual
January2023 00809-0100-3814

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.

1.3.2 Pipeline cleaning maintenance
WARNING
BURST HAZARD
Before pipeline cleaning and maintenance (“pigging operations”), remove
straightening vanes or flow conditioners. Failure to do so may cause excessive
pressure in the meter system, resulting in serious injury/death or equipment
damage.
Straightening vanes or flow profilers must be removed during pipeline cleaning
maintenance operations (“pigging operation”). If the meter run is pigged with a
flow conditioner in line, pressure may build up and cause the pipes and flanges
to burst and severely injure personnel. The excessive pressure may damage
the meter or the transducer ports may collect debris which may impede data
acquisition and flow measurement.
1.3.3 High Viscosity piping requirements
The piping requirements for High Viscosity meter applications are shown in
Figure 1-5.
Maintenance and Troubleshooting Manual Routine Maintenance
00809-0100-3814 January2023
Rosemount 3814 Liquid Ultrasonic Flow Meter 11

CAUTION
HIGH VISCOSITY FLOW MEASUREMENT METER RECALIBRATION
In high viscosity meter applications, if the connection between the upstream
meter flange (Figure 1-5, Item D) and the Venturi reducer (Figure 1-5, Item C) is
disassembled or disturbed for any reason, the meter will need to be recalibrated
in accordance with Rosemount recommendations. Alignment of this flange joint is
critical in the performance of the meter. It is recommended to consult Emerson
Customer Support for assistance when re-aligning this joint.
Failure to recalibrate the meter and correctly reinstall the flanged joint will result
in faulty flow measurement.

Error Recommended action(s)
Chord failure Chord is hard failed (Chord A, Chord B, Chord C or Chord
D) and meter is unable to obtain measurement data from
this pair of transducers.
•If Chord A is failed and no other transducers are
failed or are reporting status alerts, the issue is
most likely isolated to this pair of transducers or its
cabling. Check the transducer wiring for this pair of
transducers to make sure connections are secure and
wired correctly.
•Verify that the meter run is not partially full where the
top transducer pair are not submerged in the process
fluid.
•Verify the average gain of this transducer pair is not
above 90 dB. The gain value can be read in MeterLink
on the Monitor page.
•Remove the transducer cable from the transducer and
measure the resistance with an Ohm meter across the
two pins on the back of the transducer housing. If the
value is over 2 ohms, replace the transducers.
•If transducer cabling allows, swap cabling of failed
transducer pair with a pair with equal path lengths.
If the alarm remains active for this chord, then the
transducers are working properly. If this alarm clears
but the chord that was swapped now fails, the issue is
with the transducer.
•Collect a Maintenance Log, Configuration file and
Waveform stream file with MeterLink and contact your
Emerson Flow service representative.
CPU Module LINK LED •When connecting directly:
—Use a cross-over cable connection (P/N
1-360-01-596).
•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 LED1 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
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 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 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 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 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.
—A blocked DB API port will report “Error 10001
