damage.

1.2

A. Flange stabilizers

CAUTION!

ESCAPING GASES OR FLUIDS HAZARD

The purchaser of the meter is responsible for the selection of Daniel components/seals and materials
compatible with the chemical properties of gas flow measurement.

Failure to select the suitable meter component/seals may cause escaping gases or liquids,
resulting in injury or equipment damage.

Field hydrostatic pressure testing procedures

Daniel 3410 Series Ultrasonic Gas Flow Meters are supplied with T-Slot transducer
assemblies which are extractable while the line is pressurized.

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 over­pressurization during the test procedure.

Failure to comply may result in injury to personnel or cause damage to the equipment.

Procedure

1. Slowly vent all line pressure on the 3410 Series Gas Ultrasonic Meter to atmosphere.

2. Disconnect transducer cable from the transducer holder.

3. If installed, remove the mount cover by loosening the two mount cover captive
screws.

4. Loosen the T-Slot transducer assembly with a 1 1/4 inch (32 mm) socket. Carefully
remove the T-Slot transducer assembly.

5. Place a label on the transducer assembly to marks its location (i.e., Model 3414-A1,
A2, B1, B2, C1, C2, D1, or D2; 3412-A1, A2, B1, B2; or 3411-A). Port locations are
marked on the transducer cable as well as on cast meter housings.

6. Inspect the transducer mount threads and ensure they are clean and free of debris.

7. Apply a small amount of Nickel antiseize compound (P/N 3-9960-134) to the
threads of the Hydrotest plug (P/N 1-360-01-212) from kit (P/N 1-360-01-220) and
install it into the mount. JuniorSonic kit part numbers are listed below.

• JuniorSonic™ SP Field Hydrotest Kit (P/N 1-360-01-221)

Maintenance and Troubleshooting manual 3

Maintenance

8. Repeat Step 1 through Step 6 for the other transducer(s) being careful to note the
location of each transducer in the meter assembly.

9. Run the field hydrostatic test.

10. Reverse the steps above to reinstall the transducers into their appropriate ports.
Before reinstalling the transducer assemblies, ensure the transducer ports, mounts,
and transducer holders are clean and free of debris. Apply a small amount of Nickel
antiseize compound to the outer threads of the transducer holders before installing
them into the mounts.

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. Daniel MeterLink displays the Maintenance Logs
and Reports dialog box. 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

Maintenance log collection parametersFigure 1-2:

Maintenance

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.

Maintenance and Troubleshooting manual 5

Maintenance

Trend log collectionFigure 1-3:

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 3410 Series meter
maintenance logs. Some parameters like gain, signal level, and noise level 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. 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.

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.

Figure 1-5:

Figure 1-6:

3410 Series Gas Ultrasonic Flow Meter with flow conditioner for uni­directional flow

3410 Series Gas Ultrasonic Flow Meter with flow conditioner for bi­directional flow

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

8 Gas Ultrasonic Flow Meters

Visual inspection

Periodically inspect meter and meter run for signs of components loosening or seals
leaking. This includes:

Maintenance

Procedure

1. Fluids leaking from seals. This could be visually noticed for liquids leaking. It may be
audible for gasses leaking. Ice may also form at a point of a gas leak.

2. Movement of components that should be rigid.

3. Excessive noise due to vibration could be sign of a loose component.

Inspection should be more frequent in systems with a large amount of vibration.

from this pair of transducers.

- If Chord A is failed and no other trans-

ducers 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.

- 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 holder. If
the value is over 2 ohms, replace the
transducers.

- If transducer cabling allows, swap ca-

bling 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.

• Blocked network ports on the computer run-

ning 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 mo-

dem 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 pre-

vent 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.

- A blocked DB API port will report “Error

10001 opening database connection to
<IP address>”.

- A blocked Streaming port will report an

error message “Unable to open a control
socket”. This will occur when opening

fully seated in the transducer holder.

Note

Do not over tighten the retainer.

7. Plug the keyed chordset into the transformer assembly.

8. Thread the cable nut onto the transducer retainer. Ensure the cable nut threads are

aligned correctly and hand-tighten.

3.3.5 Modifying the calibration parameters

When transducer pairs, mounts, stalks or transducer holders are replaced, the
corresponding meter calibration parameters must be updated for accurate operation. This
means modifying the affected chord "L" dimension (LA... LD) (see Determining the “L”
Value below), average delay time (AvgDlyA... AvgDlyD) and delta delay time (DltDlyA...
DltDlyD) using the Daniel MeterLink Transducer Swap-out Wizard (see Figure 3-7).

Average delay time and delta delay time modifications

The transducer pair average delay time and delta delay time are located on the transducer
pair calibration sheet. These values must be downloaded to the appropriate meter data
points (AvgDlyA... AvgDlyD, DltDlyA... DltDlyD). The lengths of the transducers are also
included on the calibration sheet and are etched on the transducers. Likewise the lengths
of the stalk assemblies, transducer holders, and mounts are etched on the individual
components. The length of the meter body is found on the original calibration sheet
supplied with the meter.

Determining the “L” value

The value "L" is determined by adding the length of the meter body to the lengths of the
two mounts and subtracting the lengths of the transducer holders, stalk assemblies, and
transducers. This value should be written to the appropriate meter data points for each
chord that received new transducers (LA... LD). See Equation 3-1 for the “L” dimension
calculation.

54 Gas Ultrasonic Flow Meters

Daniel MeterLink Transducer Swap-out WizardFigure 3-7:

Chord “L” Dimension Calculation

Meter repairs

The chord “L” dimension is calculated from the meter housing length as well as the
transducer pair lengths, mount lengths, holder lengths, and stalk lengths as shown in
Equation 3-1. The transducer lengths are etched on the transducers. Likewise, the lengths
of the mounts, stalk assemblies, and transducer holders are also etched on the individual
components. The length of the meter body is found on the original calibration sheet
supplied with the meter.

Maintenance and Troubleshooting manual 63

Meter repairs

Procedure

1. Remove power to the meter.

2. Unscrew the cable nut from the transducer holder and then, pull the cable chordset

from the transducer holder (see Figure 3-11).

3. Cut the tie wraps for the transducer cable you are replacing.

4. Use a wrench and loosen the cable gland (where the transducer cable enters the

Base Electronics Enclosure) until the transducer cable freely slides inside the gland.

5. Remove the two bolts holding the Base Enclosure cover to the Transmitter

Electronics Enclosure using a 6mm Allen wrench.

6. Lift the Transmitter Electronics Enclosure from the Base Enclosure. It may be

necessary to remove the ground lug wire and loosen the conduit connections prior
to removal.

7. Carefully prop the Transmitter Electronics Enclosure to the side.

8. Use a flat-blade screw driver and disconnect the transducer wiring terminal block

from the Acquisition Module (see Figure 3-12).

9. Place the Transmitter Electronics Enclosure in a clean dry area. Be careful not to

dislodge or damage the enclosure gasket.

10. Remove the transducer cable wires from the terminal block and slide the existing

cable through the Base Enclosure gland.

3.5.2

Install transducer cables

1. Use the existing cable and cut the new cable (Daniel P/N 1-360-01-310) for each

chordset to same length.

2. Insert the keyed chordset into the transducer holder. Make sure the keyed parts are

correctly aligned.

3. Screw the cable nut onto the transducer holder turing clock-wise until hand-tight.

Ensure the threads are correctly aligned and do not overtighten the cable nut.

4. Route the cable through the gland on the Base Enclosure and pull the cable up

through the Base Enclosure to allow enough slack to strip the cable wire.

5. Strip the outer insulation, outer shield, and inner insulation to just inside the cable

gland using a wire stripper. Verify that insulation of individual wires were not cut
while removing outer layers. Strip each wire 1/4 inch and wire them to the
Acquisition Module terminal block. Check the label number (i.e. A1) on the
Acquisition Module and match it with the label on the cable. Securely tighten the
mounting screws of terminal block J1 and J2 as shown in Figure 3-12.

64 Gas Ultrasonic Flow Meters

Meter repairs

Model 3414 Ultrasonic Meter Acquisition Module wiringFigure 3-12:

6. Only connect wires for Chords A1, A2, B1 and B2 for 3412 meter applications or A1

and A2 for 3411 meter applications. The relative position of the contacts is shown
on the Acquisition Module label adjacent to the terminal block. When terminating
the connector wires, ensure that the contacts clamp on the bare wires and not on
the wire insulation. Leave the connector plugged into the Acquisition Module while
terminating the individual wires.

7. Once the transducers are wired correctly, tighten the cable gland so that the

transducer cable is held securely in place. Pull the cable back through the gland to
remove the slack and configure the cable to follow the same path of the existing
cable (seeFigure 3-11) and note in Section 3.5.

8. Repeat Step 1 through Step 7 if you are replacing other cables.

9. Once all of the cables are replaced, dress with tie wraps (P/N 2-4-9158-001) in

groups of two; A1 and C1, D1 and B1, A2 and C2, D2 and B2. Install one cable tie
three inches from the Base Enclosure and another near the point the cables start to
bend and separate out into their respective port (see Figure 3-11).

10. Inspect the Transmitter Electronics Enclosure gasket for wear and replace it if

necessary.

11. If replacing the gasket, lubricate it with Molykote 111

(2)

(P/N 2-9-9960-135).

12. Prop the Transmitter Electronics Enclosure at an angle on top of the Base Enclosure.
