NOTICE

It is strongly recommended that the meter be configured using an
independent (off- network) single host computer. After configuration of the
meter, the DHCP option should be disabled.

• IP Address: Enter the IP Address for the meter's Ethernet port.

The factory set IP Address is 172.16.17.200 for Daniel Gas Ultrasonic
meters or you can use 192.168.135.100 if DHCP is enabled in the meter
(see DHCP below for more details).

Dynamic Host Configuration Protocol (DHCP): Business PCs are usually
configured to work in a network environment where a DHCP server
assigns an IP address to each computer when they connect to the
network.

If a PC is configured to obtain an IP address from a DHCP server and it is
going to connect through the Ethernet Cable (1-360-01-596) to a Daniel
meter that is not connected to a network, then the DHCP server in the
meter must be enabled so it can assign an IP address to the PC when it
connects.

The DHCP server can be enabled on the meter by setting the DHCP switch
on the CPU module to the ON position.

When connecting to a meter with DHCP enabled, use the IP address of

192.168.135.100 to connect to the meter. In this mode you can create
just one Meter Directory record with this IP address to connect to all your
meters with DHCP enabled. When the connection is made, select to use
the Meter Name in the meter instead of the Meter Directory Name in
order to keep all log files and configurations separate from each meter.

Click OK to accept the changes or click Cancel to discard any changes and
return to the Meter Directory dialog box.

3 Optional feature keys

3.1 General overview of the Optional feature keys

Daniel 3410 Series Gas Ultrasonic Flow Meters offer many industry-leading features
including Chapter 21-compliant data log access, gas chromatograph (GC) interface,
AGA10 sound velocity calculation (with comparison to measured sound velocity) and
Continuous Flow Analysis diagnostics.

Daniel recognizes that these features are valuable to many, but not all customers. The
optional keys may be purchased with the meter or at a later time and this key enables all
optional features available. All keys are unique to the CPU board's serial number, so a key
entered for one meter will not work in another meter.

The Continuous Flow Analysis optional feature is enabled via a software "key" value that is
specific to the meter's CPU Board. This software feature key consists of 16 characters
divided into four hyphen-separated, 4-character groups (such as 1234-5678-90AB-CDEF).
This dialog is only available while connected to a meter with firmware that contains option
keys to enable.

3.1.1

3.1.2

In Daniel MeterLink, access the Key Manager to view key statuses, add keys or change the
key values.

Obtaining optional keys

If you do not have a valid key to enter to enable a feature, you must have the CPU board
serial number available, which displays in the Meter > Key Manager dialog and the Meter
Menu > Meter Information dialog, when you contact Daniel to obtain the key. The keys
can be given verbally over the phone or they can be e-mailed in a Key file for easy entry.

• Also see, Daniel MeterLinkHelp > Technical_Support

GC interface key

The optional GC interface feature allows the meter to read gas property data (composition
and heating value) from a Daniel gas chromatograph.

The meter can use the gas composition data to:

1. Calculate AGA8 compressibilities for converting volumetric flow rate and volumes

to standard (base) condition

2. Calculate AGA8 density for calculating mass rate and mass totals

3. To optionally calculate the AGA10 sound velocity (see AGA10 key (sound velocity

calculation)). The meter uses the GC-reported gas heating value to calculate the

energy rate and totalized energy rate values. This feature is enabled/disabled via the
GCKey data point.

4 Measurement

4.1 Flow measurement

Daniel 3410 Gas Ultrasonic Flow Meters measure the transit times of ultrasonic pulses
passing through the medium on two parallel planes. The measurement paths (also
referred to as "chords") are angled to the pipe axis, and each chord has two transducers
acting alternately as transmitter and receiver as shown in Direct path transit-time

measurement principle. This permits the transit times to be measured both with and

against the flow (upstream and downstream).

The transducers are mounted on the meter body at accurately known locations for each
pipe size so the distance L between opposing transducers and the angle are precisely
defined for the measurement path.

The 3418 combines the power of two interlocked 4-path British Gas design meters in one
flowmeter body. The second set of chords is the mirror image of the first, which allows the
meter to cancel out the effects of swirl and cross flow.

Figure 4-2: Signal Analyzer - update rate, stack size, filter and emission rate

Terminology

• Sequence - a complete cycle of firing all enabled transducers in a single round of

transducer operation.

• Stacking - the process of modifying a sequence so that each individual transducer is

fired "x" times (where x equals the stack size) before the next transducer in the
sequence is fired.

• Stack size - the multiple of times each transducer is fired before the next transducer

within the sequence is fired. (When stacking is absent or disabled, the stack size is
actually 1, because each enabled transducer is fired once during the sequence. When
stacking is applied or enabled, it is applied increments of 2, 4, 8, and 16 and are the
only stack size choices, so that each enabled transducer is fired 2, 4, 8, or 16 times
before the next transducer in the sequence is fired.)

• Emission rate - the time elapsed before the next transducer in a sequence is fired,

regardless of stack size (minimum emission rate is 2 milliseconds with the Filter ON or
OFF). We recommend the default Filter setting, which is the OFF position.

• Stack emission rate - the time elapsed before a single transducer is re-fired when

stacking is enabled (minimum stack emission rate is 2 milliseconds with the Filter OFF).

• Chords inactive or active - the exclusion or inclusion of a chord-forming pair of

transducers in the sequence of transducer operation.

• Update time - the time elapsed, in seconds, between each processing, or recalculation

of data that is collected from sequences of transducer firings.

• Batch period, or batch cycle - synonymous with Update time, as defined above.

24 Operations manual

Operations manual Measurement

DAN-20057316 January 2019

• Sample - refers to one point on the waveform as in samples per cycle. The data that is

collected from one Sequence of transducer operation. (This term is displayed in the
Daniel MeterLink™ Signal Analyzer screen, and is nearly synonymous with Sequence, as
defined above. That is, Samples/update, as displayed in the Daniel MeterLink™ Signal
Analyzer Wizard, could be interpreted as Sequences/update.) This shows the average
number of new samples collected during an update period.

4.2 Signal processing

The signal at the receiving transducer is amplified, digitized and processed digitally to
provide accurate transit time measurement.

A measure of the signal "quality" is the signal-to-noise ratio (SNR). The higher the SNR, the
better the signal. In general there are two types of noise: "white" noise and "colored" noise.
White noise is noise that occurs across the frequency spectrum and is asynchronous to the
transmitted signal. Colored noise is concentrated around a particular frequency and can
be synchronous with the transmitted signal. The meter provides two methods for
improving the received signal waveform SNR by reducing the noise energy: Stacking and
Filtering.

4.2.1

4.2.2

Stacking

Stacking is a method of firing a transducer multiple times and averaging the received
signals on a point-by-point basis.

Stacking is effective on asynchronous noise such as is typically seen with valve noise. This
method is not useful for removing synchronous noise and should not be used when there
is a great deal of signal "jitter." Meters are configured by default with a stack size of 1 (no
stacking).

Care should be taken when turning on stacking and it is recommended to consult with
Daniel Customer Service if you are unsure of how stacking a signal can affect the meter's
operation. Refer to Technical Support under the Help menu of Daniel MeterLink for
contact information.

The number of consecutive times to fire each transducer is specified via the StackSize data
point. Available stack sizes are 1 (None), 2, 4, 8, and 16. A stack size of 1 selects no
stacking (i.e., stacking disabled). Stacking is only available when the standard update rate
is selected (see Batch update period).

Filtering

Filtering applies a bandpass filter that removes noise that is above and below the
transducer frequency.

Filtering is effective on noise outside of the frequency passband of the filter (e.g., filtering
works on any noise outside of the passband of the filter).

Filtering is enabled/disabled via the Filter data point (TRUE=enable filtering, FALSE=disable
filtering). Meters are configured by default with filtering disabled. The minimum emission
rate for the gas meter is 2 milliseconds with the filter ON or OFF. We recommend the
default Filter setting, which is the OFF position.

Care should be taken when enabling/disabling filtering and it is recommended to consult
with Flow Lifecycle Services for Daniel products if you are unsure of how this change can
affect the meter's operation. Refer to Technical Support under the Help menu of Daniel
MeterLink™ for contact information.

4.2.3 Batch cycle processing

Batch update period

Calculation updates performed by the meter, for deriving volume and velocity, are based
on batches of data samples collected from sequences of transducer firings. The batch
update period is dependent upon the user specified batch update period
(SpecBatchUpdtPeriod)and the stack size (StackSize) as shown in Table 4-1. The Standard
batch update period is the default. The actual batch update period is readable via the
BatchUpdatePeriod data point.

Table 4-1: Actual meter update period

Stack size

1 (None) 2 4 8 16

SpecBatchUpdtPeriod Rapid

(250 ms)

Standard
(1000 ms)

Emission rates

The emission rate is the period between firing two different transducers. The stacked
emission rate is the period between consecutive firings of a single transducer when
stacking is used (i.e., the stack size is not set to None).

The actual emission rates used (readable via the EmRateActual and StackEmRateActual
data points) are functions of the desired emission rates, meter type, firing sequence, stack
size, and pipe diameter.

The user specifies the desired emission rates via the EmRateDesired and
StackEmRateDesired data points. If a desired emission rate is set to zero, the meter uses
the fastest possible emission rate which can be as short as is 2 milliseconds. Otherwise, the
meter uses the fastest possible emission rate that is not less than the desired value. We
recommend setting the Filter to the OFF position.

The Signal Analyzer (Meter > Signal Analyzer) is used to configure the EmRateDesired and
StackEm-RateDesired. These values are set to zero to achieve the most transducer firings
per batch update.

26 Operations manual

Smoothing

The Daniel 3410 Series Gas Ultrasonic Flow Meter applies a method for smoothing the
output (particularly the frequency output) by averaging times collected from past batch
periods with new times for the current batch period.

Operations manual Measurement

DAN-20057316 January 2019

Smoothing can be applied in the following increments: 0 (i.e., smoothing is disabled), 20,
40, 60, or 80%.

For example, setting Smoothing to 20% means that of the samples used for the current
update, 20% will be from previously collected samples and 80% will be from the newly
collected samples. Thus, if eight new samples are collected, then those eight samples
along with the last two previous samples would be used together for the current update
period calculations.

Meters are configured by default for Smoothing of 0% (only new samples are used for the
Current Update period).

4.3 Acquisition mode

Daniel 3410 Gas Ultrasonic Flow Meters have two modes of normal operation: Acquisition
and Measurement. The Acquisition mode is used to acquire the ultrasonic signals. This
mode is entered when power is applied to the meter.

Once the ultrasonic signals are acquired, the Measurement mode is entered and the flow
velocity is measured. The meter remains in the Measurement mode as long as at least one
chord is operational.

4.3.1

If while in the Measurement mode all chords fail, then the meter re-enters the Acquisition
mode. If the VelHold data point is set to a value greater than zero, then, while in the
Acquisition mode, the meter holds the average weighted flow velocity to the last good
value for up to the VelHold number of batches before setting the velocity to zero. The
VelHold default value is 0.

The Acquisition mode uses the chords' "L" dimensions (LA…LH as appropriate to the meter
type) and the specified minimum and maximum sound velocities (SSMin and SSMax)
determines the signal search range. MinHoldTime and MaxHoldTime are also used to
determine the signal search range. The meter uses the more restrictive of SSMin/
MaxHoldTime and SSMax/MinHold time.

Re-acquisition

When fewer than MinChord (default 1) chords are good, then the meter re-enters the
Acquisition mode. If MinChord is set to the number of active chords, the meter will
reacquire on the first time a chord is failed for a batch.

Note that failed for a batch is different from hard failed. A chord fails for a batch when Pct­Good[A1..H2] is less than MinPctGood.

Hard fails occur after AlarmDef number of batches in a row.

If the VelHold data point is set to a value greater than zero, then, while in the Acquisition
mode, the meter holds the average weighted flow velocity to the last good value for up to
the VelHold number of batches before setting the velocity to zero. The VelHold default
value is 0.0.

4.4 Chord gas and sound velocity measurements

At each batch update period, each firing path's transit time measurements are averaged.
The average (mean) value for each path is available via data points MeanTmA1...
MeanTmH2 (as appropriate for the meter type).

NOTICE

The data point names often use a "short-hand" way of identifying the receiving transducer.
The last two characters identify the chord (A...H) and the transducer (1=upstream,
2=downstream). For example, MeanTmA1 is the mean transit time for the chord A
upstream transducer.

The difference between a chord's average upstream transit time and average downstream
transit time is the average delta time. The chord's average times and the chord "X" and "L"
dimensions are used to calculate the gas velocity and sound velocity measured by the
chord as shown in Equation 4-1 and Equation 4-2.

Optional AGA10 sound velocity calculation and comparison

The Daniel 3410 Series Gas Ultrasonic Flow Meter offers an option to calculate the sound
velocity (using AGA10 equations and gas property data) and compare the result to the
meter- measured sound velocity on an hourly basis.

This feature is enabled via the AGA10 Key (see AGA10 key (sound velocity calculation)).
The gas property data required for using this feature can be specified via data points or
optionally read from a Daniel GC (Configure Gas Chromatograph parameters). The AGA8
Detailed Method must be selected (via the HCH_Method data point, Configure Gas

Chromatograph parameters) in order for the AGA10 calculations to be performed (as the

AGA10 calculations require AGA8 Detailed method calculation intermediate results).

Every five seconds the meter updates the AGA10-calculated sound velocity. This value is
readable via the AGA10SndVel data point and the calculation status value is readable via
the AGA10SndVelStatus data point. The status values are as listed in the table below:

Table 4-2: AGA10 calculation status

AGA10SndVelStatus value Description

0 Calculation OK (no errors)

1 Calculation not performed as the feature is not enabled (see

Configure optional keys). AGA10SnVel is set to zero.

3 Calculation not performed due to invalid AGA8 calculation

results. AGA10SndVel is set to zero.

4 Calculation error due to division by zero. AGA10SndVel is set to

zero.

Over the course of an hour (starting from the top of the hour), the meter calculates the
average measured sound velocity (the average of the average weighted sound velocity)
and the average AGA10-calculated sound velocity. At the end of the hour, the two
averages are compared; the comparison error (%) is readable via the SndVelCompErr data
point.

Note that the comparison error is only calculated at the end of the hour if during the hour
all of the following are true:

4.4.3

• No AGA10 sound velocity calculation errors occurred (i.e., AGA10SndVelStatus always

equal to 0),

• the measured flow velocity was always above the minimum sound-speed-check flow

velocity (specified via the SndSpdChkMinVel data point which has a default value of 1
m/ s), and

• the measured sound velocity was always valid (as indicated by the QMeterValidity data

point).

Average weighted gas flow velocity

When all active chords are non-failed, the average weighted gas flow velocity is a weighted
sum of the chord velocity measurements as shown in Equation 4-4 where the chord
weights are determined by the meter geometry.

Average weighted flow velocity using chord proportions

In the event of one or more chord failure(s), the meter operation is dependent upon the
number of non-failed chords. If there is at least one operating chord, then the meter uses a
velocity estimation method described in the following paragraphs.

Operations manual Measurement

DAN-20057316 January 2019

If all chords fail, then the meter re-enters the Acquisition mode as described in the Re-

acquisition section.

The meter partitions the velocity range (for forward and reverse flow) into ten
consecutive, non- overlapping "bins" (where the velocity range is as specified via the
MeterMaxVel data point).

The meter maintains a set of bins for each active chord where each bin contain three data
values: (1) the chord's average velocity (within the bin's velocity range), (2) the chord's
average proportion value, and (3) an indicator that the value is still the default (Is[Fwd/
Rev]Prop[A..H]DfltBin[1..10]). A chord proportion value is the ratio of the chord velocity
to the average weighted flow velocity as shown in Equation 4-5 below. The default
indicator is used to determine if a bin's velocity and proportion data values have been
updated from their initialized values. The bins are initialized with the average velocity over
the bin's range and meter-geometry-dependent proportion values. All default indicators
are initialized to TRUE. The bin data is stored in non-volatile memory.

When the meter has operated for a user-specified number of consecutive batches without
any chord failures, the meter updates each chord's data values for the bin containing the
chord velocity as shown in Equation 4-6 and sets the bin's default indicator to FALSE. The

PropUpdtBatches data point, configurable via the Daniel MeterLink Edit/Compare
Configuration screen, specifies the number of consecutive failure-free batches required

for updating the bin data (range: [1, 1000], default: 24). The NumVals data point (that

For each non-failed chord, the interpolated proportion value used in Equation 4-7 is
calculated as follows:

• If the chord's velocity is surrounded by non-default (average velocity, average

proportion) data pairs, then the interpolated proportion is the linear interpolation
between the two data pairs.

• If the chord's velocity has a non-default (average velocity, average proportion) data

pair on one side of it but not the other, then the interpolated proportion is the data pair
average proportion.

• If there are only default (average velocity, average proportion) data pairs, then the

interpolated proportion is the corresponding bin's default average proportion value.

4.5 Volumetric flow rate values

The Daniel 3410 Series Gas Ultrasonic Flow Meter meter provides three volumetric flow
rate values: raw, (expansion-corrected and/or profile-effect corrected) flow-condition, and
base- condition. Note that a positive volumetric flow rate indicates flow in the forward
direction whereas a negative volumetric flow rate indicates flow in the reverse direction.

SpecZFlow and SpecZBase data points), and (2) the flow-condition temperature and
pressure to be live or fixed. If AGA8 calculations are not performed (i.e., neither internally

4.5.6 Volume

The Daniel 3410 Series Gas Ultrasonic Flow Meter provides forward and reverse volume
accumulators for each of the three volumetric flow rate values: raw, flow-condition (raw
with expansion and/or profile correction), and base-condition.

Each volume accumulator is actually stored as a data pair: (64-bit unsigned integer
portion, 32-bit floating point fractional portion). For example, a volume of 12345.750 m
is stored as 12345 m3 for the integer portion and 0.750 m3 as the fractional portion. Note
that while a volumetric flow rate can be positive (indicating forward flow) or negative
(indicating reverse flow), the volume accumulators are always positive values.

The non-volatile volume accumulator data points are as listed in the table below:

The sign of the energy rate indicates the flow direction: a positive value indicates flow in
the forward direction, a negative value indicates flow in the reverse direction.

The energy rate validity is indicated by the EnergyRateValidity data point TRUE(1)
indicates valid). The energy rate is valid if the base-condition volumetric flow rate is valid
(indicated by QBaseValidity where TRUE(1) indicates valid) and if the in-use gas properties
are valid (indicated by AreGasPropertiesInvalidInUse where FALSE(0) indicates valid).

The energy rate is accumulated into the corresponding direction energy total regardless of
the energy rate validity.

The forward and reverse direction energy totals are each stored in non-volatile memory as
a data pair: a 64-bit unsigned integer portion and a 32-bit floating point fractional portion.
For example, an energy total of 12345.750 MJ is stored as 12345 MJ for the integer portion
and 0.750 MJ as the fractional portion. Note that while the energy rate can be positive
(indicating forward flow) or negative (indicating reverse flow), the energy totals are always

4.6 3410 Series gas flow meter characterizations

Symmetry

For Daniel 3410 Series Gas Ultrasonic Flow Meter SeniorSonic meters only, the following
flow characterizations are calculated/estimated: symmetry, cross-flow, chord turbulence,
profile factor, and swirl angle. Alarm limits are provided for the chord turbulence and swirl
angle values.

Symmetry is a dimensionless measure of the flow symmetry comparing the upper chords
to the lower chords and is readable via the Symmetry data point. Ideally the Symmetry
should be 1.0.

Cross-flow

Cross-flow is a dimensionless measure of the flow symmetry comparing the chords on one
side of the meter to the chords on the other side. It is readable via the CrossFlow data
point. Ideally the Cross-flow should be 1.0.

Chord turbulence

Chord Turbulence is a estimate of the turbulence (percentage) at a chord location. A value
is calculated for each active chord and is readable via the TurbulenceA, TurbulenceB,
TurbulenceC, TurbulenceD, TurbulenceE, TurbulenceF, TurbulenceG, or TurbulenceH
data points. A value of 0% indicates no appreciable turbulence.

Profile Factor

The profile factor is a dimensionless ratio of the inner chord velocities to the outer chord
velocities. It is readable via the ProfileFactor data point. Ideally the Profile Factor should be

1.17 for an 8-path transmitter head.

Swirl angle

The swirl angle is an estimate of the swirl (to the nearest degree) and is readable via the
SwirlAngle data point. It is calculated as a function of the meter body style and Profile
Factor (see above). A value of 0 degrees indicates no appreciable swirl.

5.1.1 Calibration methods

The Daniel 3410 Series Gas Ultrasonic Flow meter uses two calibration steps: "dry"
calibration and "wet" calibration.

In this methodology, the "dry-calibration" values are set by Daniel at the factory and are
not expected to be modified; the "wet-calibration" values are expected to be set as the
result of a user flow calibration (if desired). These two calibration methods are explained in
further detail below.

Important

The WRITE PROT. switch on the CPU Module must be disabled (OFF) before writing
calibration factors to the meter.

After the meter is configured, enable the WRITE PROT. switch (ON) to write-protect the
configuration.

calibration: 12-point piece-wise linearization, a third-order polynomial, or none. The wet
calibration method is selected via the CalMethod data point with "None" being the default
value. The wet calibration gas flow velocity is calculated from the dry calibration gas flow

Piece-wise linearization for wet calibration

If the 12-point piece-wise linearization (PWL) wet calibration method is selected, then the
dry-calibration gas flow velocity is calculated as shown in Wet calibration - 12-point piece­wise linearization.

The inputs to the 12-point piece-wise linearization are the (up to) 12 pairs of volumetric
flow rates and meter factors for each flow direction ([FwdFlwRt1, FwdMtrFctr1], ...,
[FwdFlwRt12, FwdMtrFctr12] for forward flow; [RevFlwRt1, RevMtrFctr1], ...,
[RevFlwRt12, RevMtrFctr12] for reverse flow). Refer to Calibrate meter factors to
configuring these data points using Daniel MeterLink.

NOTICE

The input flow rates should be entered in descending order (highest first) with their
corresponding meter factors. If these are entered in the wrong order, the meter will still
work but the accuracy may be affected. The meter will not accept negative values, so only
positive values should be entered for both forward and reverse flow rates. If fewer than 12
points are to be used, the unused flow rate and meter factor pairs should be set to 0 and 1
respectively.

If no wet calibration is selected, then the wet calibration gas flow velocity is equal to the
dry calibration gas flow velocity.

Triggered delta volumes

The "triggered delta volume" feature provides the ability to measure total gas flow volume
(flow- and base-condition) between two successive external event triggers.

To trigger an event, set the DoUpdtTrigDeltaVols data point to TRUE. This causes the
meter to save the current accumulated flow- and base-condition volume values (forward
and reverse). The meter then calculates the difference between these values and the
corresponding values saved from the previous event trigger. Finally the meter writes the
delta volume values to the appropriate data points (TrigDeltaPosVolFlow,

TrigDeltaNegVolFlow, TrigDeltaPosVolBase, and TrigDeltaNegVolBase) and sets the
DoUpdtTrigDeltaVols data point to FALSE to clear the trigger and indicate the calculation

completion.

48 Operations manual

Operations manual Configurations

DAN-20057316 January 2019

The triggered delta volume functionality is retained across power cycles as the
accumulated volumes values at the last event trigger are saved in non-volatile memory.

The delta volume data points are stored internally in non-volatile memory as double­precision floating point numbers. The delta volume data points can be read via Modbus as
either 32-bit floating point values or as integer values (using the [overflow,lower] LONG
register pair in a manner similar to reading the accumulated volumes).

Suggested user access logic

The following pseudo-code demonstrates the logic to access the triggered delta volume
functionality:

• INITIAL SET-UP:

Ensure Modbus units are set-up as desired: set Modbus register 10026 (UnitsSystem)
to 0 for U.S. Customary units or to 1 for metric units.

• Periodic Loop:

Wait for external event for synchronizing the start of the meter delta volumes.
Send trigger Modbus message: set Modbus register 12199 (DoUpdtTrigDeltaVols) to 1
(TRUE).
Read trigger Modbus register 12199 (DoUpdtTrigDeltaVols) in a loop until it is read as
0 (FALSE) indicating that the delta volumes have been updated.

5.1.2

Read delta volume registers (either the FLOAT registers or the LONG register pairs) in a
single Modbus read. If the delta volume registers are read as LONG register pairs, calculate
each delta volume as follows:

Equation 5-5: Triggered delta volume

DeltaVolume = Overflow × 1e9 + Lower

where

DeltaVolume = triggered delta volume (forward or reverse, flow-condition or base­condition) (m3 or ft3) (TrigDeltaPosVolFlow, TrigDeltaNegVolFlow,
TrigDeltaPosVolBase, TrigDeltaNegVolBase)

Overflow = triggered delta volume overflow integer value (forward or reverse, flow­condition or base-condition) (1e9m3 or 1e9ft3)

Lower = triggered delta volume lower integer value (forward or reverse, flow-condition
or base-condition) (m3 or ft3)

5.2 Calibrate analog inputs and outputs

NOTICE

The WRITE PROT. switch on the CPU Module must be disabled or the calibration values will
not be updated for a meter.

An analog input can be calibrated regardless of the corresponding input type, pressure of
temperature. However, if the corresponding input type is selected as Live, then the input
being calibrated is considered to be invalid and the in-use value depends upon the
FlowPOrTSrcUponAlarm selection (see above). In this case, the appropriate data point
(FlowPressureWhileCal, FlowTemperatureWhileCal) is set to the in-use value so that it
can be logged in the optional log.

The offset and gain can be reset to the default values (0 and 1, respectively) by clicking the
Reset Defaults button.

NOTICE

Clicking the Reset Defaults button writes the offset and gain immediately - the previous
values cannot be restored.

Click the Edit Scaling button to modify the input scaling.

NOTICE

Changes made to an analog input's offset, gain, and scaling values are written to the log.

From Daniel MeterLink, select Calibrate to make changes using the Analog Inputs Wizard.

Procedure

1. Choose the analog input to calibrate, either temperature or pressure and click Next.
The Current > Calibration screen shows the current offset and gain and the input
scaling (i.e., the pressures or temperatures corresponding to the minimum (4 mA)
input and maximum (20 mA) inputs).

2. Click Next to proceed to the Calibration > Method screen then, select either the
offset or two-point calibration methods.

• The Offset method requires a single calibration point and only affects the input's

calibration offset parameter.

• The two-point calibration requires calibrating at two different points (ideally far

apart in value) and affects the input's calibration offset and gain parameters.
Depending upon the selected calibration method, either one or two screens will

follow when the Next button is clicked.

3. The screen(s) displays the current (live) reading. When the input is stable, click the
Hold button to freeze the current reading.

4. Enter the correct value in the Actual edit box. Finally, the Finish screen shows the
new calculated offset and gain values.

5.3 Calibrate meter factors

The factory calibrated flow velocity is the result of applying a third-order polynomial
equation (see Third-order polynomial for wet calibration) to the average weighted flow
velocity. Daniel 3410 Gas Ultrasonic Flow Meters are factory calibrated and the default
calibration settings are recommended.

5.3.1

Flow calibration

Daniel 3410 Gas Ultrasonic Flow Meters can be calibrated during flowing conditions by
selecting the calibration type in Daniel MeterLink from Calibration > Flow Calibration.

In a timed calibration, the meter records the volume through the meter over a user
specified period of time for a calibration run.

A gated calibration records the volume seen between switch closures directly from a
prover for the number of passes it takes for the prover to make a run. Use the spin buttons
or type in the number of passes of a prover to make a run. Calibration Gating configuration
parameter selections are:

• Edge gated, active high

5.5 Configure digital input/outputs

Digital input

The Daniel 3410 Gas Ultrasonic Flow Meters provides one digital input (referred to as DI1).
The polarity of the input is configured via the DI1IsInvPolarity data point as follows:

• FALSE - normal polarity (default setting), or

• TRUE - inverted polarity

The digital input is not configurable via the Daniel MeterLink Field Setup Wizard. It must be
configured via the Daniel MeterLink Tools|Edit/Compare Configuration.

Digital input calibration

The IsDI1UsedForCal specifies whether digital input 1 (DI1) is used for general purpose
(when set to FALSE) or for synchronizing calibration (when set to TRUE). If used for
calibration, the polarity is determined by the IsDI1ForCalActiveLow data point select one
of the following:

• FALSE - general purpose (default setting), or

• TRUE - for synchronizing calibration

The IsDI1ForCalActiveLow data point specifies the polarity for digital input 1 (DI1) when it
is configured (via IsDI1UsedForCal) for use in synchronizing a calibration. See also
IsDI1ForCalStateGated.

• FALSE = Cal Active High

• TRUE = Cal Active Low (default)

The IsDI1ForCalStateGated data point specifies the calibration gating for digital input 1
(DI1) when it is configured (via IsDI1UsedForCal) for use in synchronizing a calibration.
When FALSE, the calibration is started/stopped via an inactive->active edge; when TRUE,
the calibration is started via an inactive->active state change and stopped via an active­>inactive state change. The active edge/state is specified via the IsDI1ForCalActiveLow
data point.

• FALSE = Cal Edge Gated (default)

• TRUE = Cal State Gated

For detailed digital proving configuration, refer to Flow calibration.

Digital output

Select the function for which the digital output should be configured. Available options are
validity and direction.

The inverted operation option is useful if the output of the ultrasonic meter is reversed
from what a flow computer is expecting. This means that if the output normally outputs a
HIGH for a TRUE condition, selecting this checkbox will change the output to output a
LOW for a TRUE condition.

5.6 Outputs test mode

The Daniel 3410 Gas Ultrasonic Flow Meters provides a mode of operation for testing the
frequency, current (analog) and digital output signals. Entering, configuring, and exiting
this mode is accomplished by setting data points using the Daniel MeterLink Tools >
Outputs Test.

Figure 5-12: Meter Outputs Test page

Note

The AO2 is only available with CPU module, part number 1-360-03-010.

The Outputs Test dialog box allows you to monitor the live values of all the frequency,
current (analog) and digital outputs. Additionally the outputs can be set into a Test mode
to force the outputs to a specific user defined value. This dialog box is only available while
connected to a meter.

When the dialog box first opens, the available Outputs show the current "Live" values the
outputs are driving. The LED Test mode will remain gray while not in Test mode.

62 Operations manual

Operations manual Configurations

DAN-20057316 January 2019

To fix the frequency and current outputs to a user-defined value, enter the desired
percentage of full-scale into the Output setting. For Daniel 3410 Gas Ultrasonic Flow
Meters, each available output has individual output control and can be set from 0 to 150%.
The 100% Scaling indicates the full scale value for the frequency outputs and can be
changed from the Field Setup Wizard.

Click the Start button to enter Test mode. Each output has its own start button, so each
available output can be tested one at a time. The frequency and current outputs will not
be updated until the end of the next batch cycle. Once the Test mode LED turns green, the
output values displayed represent the values the outputs are driving under test.

The frequency outputs for both the A and B channels are displayed. If Channel B zero on
error is selected in the Field Setup Wizard the Channel B phase will show zero because the
frequency output is considered invalid during test mode.

The K-Factor and Inverse K-Factor will be displayed for the frequency outputs configured
for Volumetric flow rate. The values will be displayed next to the label for the associated
frequency output.

To set the digital outputs to a known state, select the Test High or Test Low for the
appropriate digital output and click the Start button for the digital output. Once the Test
mode LED turns green, the value displayed for the outputs will represent the values the
outputs are driving under test.

The timeout for each output in test mode is reset by Daniel MeterLink each time the values
are updated. As long as this dialog is open with an output in test mode, the output will
remain in test mode or until the Stop button is clicked to end the test.

In the event communications are lost between Daniel MeterLink and the meter (before a
test mode is stopped), the meter will automatically end the test mode after the
NonNormalModeTimeout has expired. This can be from 1 to 30 minutes depending on its
settings. By default, the timeout is set to two minutes.

The Output setting can only be changed while out of Test mode. To end the Test mode,
click Stop and wait for the end of the batch and the Test mode LED to turn gray to indicate
the Outputs are driving live values.

Click Cancel to close the dialog box. If the meter is currently in Test mode when Cancel is
clicked, Daniel MeterLink will first end the test mode before returning to the Main Screen.

5.7 Configure temperature and pressure

5.7.1 Flow-condition pressure and temperature

The flow-condition pressure and temperature are used by the Daniel 3410 Series Gas
Ultrasonic Flow Meter for various calculations such as:

• Expansion correction

• Flow profile correction (JuniorSonic™ meters only)

• Calculation of base (standard) condition volumetric flow rate and volumes

• Optional AGA10 sound velocity calculation

Model 3418 GUSM 63

Configurations Operations manual

January 2019 DAN-20057316

Configuration

The flow-condition pressure and temperature are individually configurable (via the
EnablePressureInput and EnableTemperatureInput data points) to be:

• Disabled (0),

• Live (1) (4-20 mA input signal)

• Fixed (2)

If an input is live, then the values corresponding to the minimum and maximum input (4
and 20 mA, respectively) are specified via data points (MinInputPressure,
MaxInputPressure, MinInputTemperature, MaxInputTemperature).

If an input is fixed, then its value is specified via a data point (SpecFlowPressure,
SpecFlowTemperature).

Alarm limits can be specified for each input (LowPressureAlarm, HighPressureAlarm,
LowTemperatureAlarm, HighTemperatureAlarm). Additionally, the flow-condition
pressure is configurable to be gage or absolute (via the InputPressureUnit data point). If
the pressure is gage, then the atmospheric pressure must be specified (via the
AtmosphericPress data point). See Configure the temperature parameters for the meter
and Configure the pressure parameters for the meter for details on configuring the flow­condition pressure and temperature.

Another data point (FlowPOrTSrcUponAlarm), common to both pressure and
temperature, is used to specify the data source to use when the selected input data is
invalid (i.e., value at or outside its alarm limits or a live input in calibration) as either:

• Last good value (0), or

• Fixed value (1).

This data point (FlowPOrTSrcUponAlarm) is configurable via the Daniel MeterLink Field
Setup Wizard > Temperature and Pressure page under Alarm Selection. It is also
configurable via the Daniel MeterLink Tools > Edit/Compare Configuration screen. The
default is to use the last good value.

Data updates

The Daniel 3410 Series Gas Ultrasonic Flow Meter samples the input analog signal(s) and
updates the corresponding data point(s) (LiveFlowPressure, LiveFlowTemperature) once
per second regardless of the input selection (disabled, live, or fixed).

Every five seconds, the meter updates the "in-use" flow-condition pressure and
temperature values (FlowPressure, AbsFlowPressure, FlowTemperature) depending
upon the input selection, validity of the input data, and the selected data source upon
alarm according to Table 5-7.

• Fixed temperature - If Fixed was selected on the Daniel MeterLink Startup Page for

Temperature It will also be enabled if a live temperature input was selected. Enter a
fixed value to use for calculations if the live input goes into alarm. Enter an average
temperature of the process fluid.

• Temperature alarm - Enter the low and high alarm limits. A temperature reading

outside of these limits causes a Temperature Validity alarm. The Alarm selection
determines what value to use while a live input is in alarm. This value is common with
the pressure Alarm selection so when one is changed, the other will change to match.

5.7.3 Configure the pressure parameters for the meter

• Pressure reading - Select either Gage or Absolute for the type of pressure reading

desired. If a live pressure transmitter is connected, select the type of reading the
transmitter outputs. If Absolute is selected, you must also enter the Atmospheric
pressure.

• Live pressure - Enter in the scaling for the transmitter connected to the analog input.

Min. input is the zero scale pressure of the transmitter (i.e. 1 Volt or 4mA). Max. input is
the full scale pressure of the transmitter (i.e. 5 Volts or 20 mA).

• Fixed pressure - Enabled if Fixed was selected for Temperature for meter corrections on

the Startup Page. It will also be enabled if a live temperature input was selected to
allow you to enter a fixed value to use for calculations if the live input goes into alarm.
Enter an average pressure of the process fluid.

• Pressure alarm - Enter the low and high alarm limits. A pressure reading outside of

these limits causes a Pressure Validity alarm. The Alarm selection determines what
value to use while a live input is in alarm. This value is common with the temperature
Alarm selection so when one is changed, the other will change to match.

5.8 Configure Gas Chromatograph parameters

Use the Meter > Field Setup Wizard menu and enable the View Gas Chromatograph
setup checkbox. Configure the following parameters to setup a serial port as a Modbus

master for polling a GC.

• Port - Select which port will be connected to the GC. While a serial port is configured for

communications to a GC, it will not act as a Modbus slave device for communications
from Daniel MeterLink or a SCADA system

• GC protocol - Select the protocol for which the GC is configured. The Daniel Gas

Ultrasonic meter uses 7 data bits, Even parity, and 1 stop bit for ASCII Modbus and 8
data bits, No parity, and 1 stop bit for RTU Modbus.

• GC baud rate - Select the baud rate for which the GC is configured.

• GC comms address/unit identifier - Enter the Modbus ID of the GC.

Gas properties

Gas property data (composition and heating value) are used by the meter for AGA8
calculations (for converting to base or standard volumes and for mass calculation), for
energy calculation, and for optional AGA10 calculations (sound velocity calculation and
comparison).

The data are also used by JuniorSonic™ meters when the profile correction factor is to be
calculated by the meter (rather than fixed or a default value). See Table 5-12 for GC
registers polled by the meter. The gas property data can either be fixed (specified via data
points) or optionally read from a Daniel™ Gas Chromatograph (GC). Reading the gas
property data from a GC requires a valid GC feature key (See GC interface key). Use the
Field Setup Wizard in Daniel MeterLink™ to configure these parameters.

Fixed gas property data

If the data is fixed, then the heating value and its reference temperature are specified via
the MeasVolGrossHeatingVal and RefTemperatureHV data points, respectively; the gas
components are specified via the data points listed in Table 5-8 below. Fixed gas property
data is always assumed to be valid.

NOTICE

If the gas composition is specified from within Daniel MeterLink, the data point's unit is
mole percentage, not mole fraction (as the data point name would imply).

good value (0) or Fixed value (1). When Last good value is selected, the "In-Use" gas
property data is not updated with the invalid GC-read gas property data. When Fixed value
is used, the "In-Use" gas property data is updated with the fixed gas property data.

The meter maps the appropriate input gas property data points (fixed or GC-reported as
discussed above) to the corresponding "In-Use" data points (the HeatingValueInUse data
point and the gas composition data points listed in the Table 5-10 below).

(0.30x1%=0.30%) is added to NHeptaneInUse, and 10% (0.10x1%=0.10%) is added to
NOctaneInUse.

The GC-reported NeoPentane component (NeoPentaneGC) quantity is added to the
IsoPentane component (IsoPentaneInUse).

The validity of the "In-Use" gas property data is readable via the
AreGasPropertiesInvalidInUse data point where TRUE(1) indicates invalid data and
FALSE(0) indicates valid data. The validity of the "In-Use" gas property data is a function of
the validity of the selected source data. If the source data is selected as Fixed, then the "In­Use" gas property data is valid (since the fixed data is assumed to be valid). If the source
data is selected as Live - GC, then the "In-Use" gas property data is valid only if the GC-read
gas property data is valid.

Optional gas chromatograph interface

The Daniel 3410 Series Gas Ultrasonic Flow Meter can optionally interface with any Daniel
gas chromatograph (GC) that supports the SIM 2251 mode to read gas property data
(such as for AGA8, AGA10, energy rate, mass rate, and/or profile correction calculations).

NOTICE

The gas chromatograph interface is an optional feature that requires a valid GC feature
key. Refer to GC interface key.

The following table lists the Gas Chromatograph SIM registers polled by the meter. Also

Note

Components read from the register 3001-3016 had 100 subtracted from them by the GC.

The Daniel Gas Ultrasonic Meter must add 100 to each ID read from the GC before looking
it up in this table.

Gas property data

The gas property data read from the GC includes gas composition, heating value, and
specific gravity (relative density).

The gas composition includes the 21 standard components plus C6+ and Neopentane (see

Table 5-9 for a list of data point names). Refer to In-Use gas property data for further

information on how the GC-read gas properties are mapped to the 'in-use' gas property
data points.

The GC-read heating value and specific gravity are stored in the HeatingValueGC and
SpecificGravityGC data points, respectively.

Data polling

The meter periodically polls the GC looking for data updates. If the meter is
communicating normally with the GC, then it polls the GC every one minute looking for an
update (i.e., a change in the GC analysis time). Otherwise, the meter polls the GC every 15
seconds.

When the meter determines that a GC update is available for the specified stream number,
it then reads the GC data using multiple reads one second apart until all the data is read.
The GC analysis time is read again at the end of the data collection to determine if another
update occurred during the data collection (i.e., the data is not all from the same update).
If so, the meter discards the gas property data just read and begins looking immediately
for the next update.

If the meter cannot successfully communicate with the GC after four consecutive polls (15
seconds apart), then the meter indicates the communication alarm via the IsGCComErr
data point with the GCCommStatus data point indicating an error code (listed in Table

5-14 below).

Configure the Continuous Flow Analysis features of the Daniel Ultrasonic meter. This
Daniel MeterLink™ Field Setup Wizard page is displayed only if the View Continuous Flow
Analysis setup was selected on the Startup Page and you have a valid Continuous Flow
Analysis key.

These features require that the meter baseline be set using the Tools > Set Baseline
Wizard.

• Flow limits - low and high flow velocity limits.

• SOS comparison (requires AGA 8 Detail method to be used) - compares the meter

average speed of sound to the AGA 10 calculated speed of sound.

• Liquid detection - identifies when liquids may be present in the bottom of the meter run

base on the meter's flow characteristics.

• Abnormal profile - identifies if the meter flow profile has shifted from the original

baseline profile of the meter.

• Blockage - identifies a possible blockage of an upstream flow conditioner.

• Internal bore buildup - indicates that the flow characteristics have changed indicating a

build up on the internal bore of the meter.

Set Baseline parameters

Select the direction to baseline and what data to use to perform the baseline. The wizard
will step you through setting a baseline in one direction.

It is necessary to baseline the meter in both directions if the meter will be operating in a bi­directional application. For meters only operating in a uni-directional application, the
meter only needs one baseline. The status message displayed on the Meter monitor
screen about the baseline not being set can simply be acknowledged to clear the alarm for
a flow direction you do not want to baseline.

Setting baselines in two directions is only necessary if the meter is installed in a bi­directional application. Flow through the meter in one direction can be quite different
from flow through a meter in the opposite direction. This could be because of flow
conditioners, thermowells, or elbows.

If a flow computer or SCADA system is used to write these values to the meter, they do not have to be entered at this time.

6.1 Archive logs

The Daniel 3410 Series Gas Ultrasonic Flow Meters provides five types of data logs (daily,
hourly, audit, alarm, and system logs).

Each log type is discussed in detail below followed by Daniel MeterLink instructions to read
(and optionally save) meter log records (Options for reading daily and/or hourly log

records).

6.1.1 Daily and Hourly log data points actions

Five different log data point actions are supported by the daily and hourly logs: snapshot,
average, flow-gated (average), totalize, and macro as described below:

• SNAPSHOT: causes the data point's value at the log time to be recorded.

• AVERAGE: causes the data point's average value over the log interval (day or hour) to

be recorded.

• FLOW-GATED: causes the data point's flow-gated average value over the log interval

(day or hour) to be recorded. A point's flow-gated average is the average of its values
when the flow is above the low-flow cut-off. If the flow does not exceed the cut-off
during the interval, then the data point's flow-gated average is the same as its regular
(non-flow- gated) average.

• TOTALIZE: causes the data point's accumulated value over the log interval (day or

hour) to be recorded.

• MACRO: causes the (boolean) data point's 'latched' value over the log interval (day or

hour) to be recorded. A (boolean) data point's latched value indicates if the point was
ever TRUE during the log interval (where a TRUE value is represented by a 1 and a FALSE
value is represented by a 0). This allows a group of boolean data points to be grouped
into a single integer value where each bit represents the latched value of a single
boolean data point.

Daily log

The Daniel 3410 Series Gas Ultrasonic Flow Meter stores a daily log record once per day at
the specified contract hour.

(Refer to the Daniel MeterLink Help files for information on specifying the ContractHour
data point.)

The meter can store up to 365 daily records. The user can select whether old, unread
records can be overwritten by new records when the log becomes full via the data point

DoOverwriteUnreadDailyLog. This point can be modified using the Daniel MeterLink
Tools > Edit/Compare Configuration screen. The default is to overwrite old, unread

records. Refer to Options for reading daily and/or hourly log records for information on
reading records and marking records as read. The data point IsDailyLogFull indicates
whether or not the daily log is full and cannot overwrite old, unread records.

Directory Operations manual

January 2019 DAN-20057316

The user can select whether old, unread records can be overwritten by new records when
the log becomes full via the data point DoOverwriteUnreadHourlyLog.

This point can be modified using the Daniel MeterLink™ Tools > Edit/Compare
Configuration screen. The default is to overwrite old, unread records. Refer to Options for

reading daily and/or hourly log records for information on reading records and marking

records as read. The data point IsHourlyLogFull indicates whether or not the hourly log is
full and cannot overwrite old, unread records.

The data points included in the hourly log and the corresponding log action are as shown
in the table below. Data points required by the API Chapter 21 standard are marked with
an asterisk (*). For information on a particular data point, consult Daniel MeterLink online
help.

Directory

which data point changed, the date and time of the change, and both the 'as-found' and
'as-left' values.

The meter can store up to 3000 audit records. The user can select whether old, unread
records can be overwritten by new records when the log becomes full via the data point

DoOverwriteUnreadAuditLog. This point can be modified using the Daniel MeterLink
Tools > Edit/Compare Configuration screen. The default is to overwrite old, unread

records. Refer to Options for reading audit, alarm, and/or system log records for
information on reading records and marking records as read. The data point
IsAuditLogFull indicates whether or not the audit log is full and cannot overwrite old,
unread records.

The data points monitored and collected for the audit log are as shown in Audit log
through Event log: alarm/audit below. The points are grouped and, within each group, are
listed alphabetically.

The groupings are as follows:

• AGA8

• AGA10

• Calibration

• Chord Proportions

• Co-located meter

• Communications

• Data Logging

• Expansion Correction

• Flow analysis

• Frequency, Digital, and Analog Signals

• Gas chromatograph

• General

• HART

• Indicators

• Local display

• Meter Information

• Pressure & Temperature

• Reynolds Number Calculation

• Signal Processing

• Tracking
