THEORY OF OPERATION The Rosemount 3300 Series Radar Transmitter is a smart, two-wire

continuous level transmitter that is based on Time Domain Reflectometry
(TDR) principles. Low power nano-second-pulses are guided along a probe
immersed in the process media. When a pulse reaches the surface of the
material it is measuring, part of the energy is reflected back to the transmitter,
and the time difference between the generated and reflected pulse is
converted into a distance from which the total level or interface level is
calculated (see below).

Figure 2-1. Measurement
Principle.

The reflectivity of the product is a key parameter for measurement
performance. A high dielectric constant of the media gives better reflection
and a longer measuring range. A calm surface gives better reflection than a
turbulent surface.

APPLICATIONS The Rosemount 3300 Series Radar Transmitter program is suited for

aggregate (total) level measurements on most liquids, semi-liquids, and
liquid/liquid interfaces.

Guided microwave technology offers highest reliability and precision which
ensure measurements are virtually unaffected by temperature, pressure,
vapor gas mixtures, density, turbulence, bubbling/boiling, low level, varying
dielectric media, pH, and viscosity.

Guided wave radar technology in combination with advanced signal
processing make the 3300 transmitters suitable for a wide range of
applications:

Figure 2-2. Application
examples

Boiling conditions with
vapor and turbulence. For
these applications the
Coaxial probe is particularly
suitable.

APPLIC TURBULENCE

APPLIC BRIDLE

The 3300 Series of
transmitters is well suited
for bridle applications such
as distillation columns.

Separator tank. The model
3302 measures both level
and interface level.

APPLIC SEPARATOR

The Rosemount 3300
series is a good choice for
underground tanks since it
is installed on the tank top
with the radar pulse
concentrated near the
probe. It can be equipped
with probes that are
unaffected by high and
narrow openings or nearby
objects.

SYSTEM ARCHITECTURE

Figure 2-4. System architecture.

The Rosemount 3300 Series Radar Transmitter is loop-powered which
means it uses the same two wires for both power supply and output signal.
The output is a 4-20 mA analog signal superimposed with a digital HART
signal.

By using the optional HART Tri-loop, it is possible to convert the HART signal
to up to three additional 4-20 mA analog signals.

With the HART protocol it is possible to use multidrop configuration. In this
case communication is restricted to digital since current is fixed to the 4 mA
minimum value.

The transmitter can be connected to display Model 751 Field Signal Indicator
or it can be equipped with an integral display.

The transmitter can easily be configured by using a HART 275/375
Communicator or a PC with the Radar Configuration Tool software.
Rosemount 3300 Series transmitters are also compatible with the AMS

™

(Asset Management Solutions™) software which also can be used for
configuration.

Dead Zones The measuring range depends on probe type and properties of the product.

The Upper Dead Zone is the minimum measurement distance between the
upper reference point and the product surface. The Upper Dead Zone varies
between 4 - 20 in. (0.1 and 0.5 m) depending on probe type and product.

At the end of the probe the measuring range is reduced by the Lower Dead
Zone. The Lower Dead Zone also varies depending on probe type and
product.

PROCESS CHARACTERISTICS

The Rosemount 3300 Series has a high sensitivity due to its advanced signal
processing and high signal to noise ratio, which makes it able to handle
various disturbances. However, the following circumstances should be
considered before mounting the transmitter.

Coating Coating on the probe should be avoided since the sensitivity of the transmitter

may be decreased leading to measurement errors. In viscous or sticky
applications, periodic cleaning may be required.

For viscous or sticky applications, it is important to choose a suitable probe:

Coaxial Twin Lead Single Lead

Maximum viscosity

500 cP 1500 cP 8000 cP

Coating/Build-up

Coating not recommended Thin coating allowed, but no

bridging

(1) Consult factory if agitation/turbulence and high viscous products.

Coating allowed

(1)

Maximum measurement error due to coating is 1-10 % depending on probe
type, dielectric constant, coating thickness and coating height above product
surface.

Bridging Heavy coating that results in product bridging across the two probes for twin

lead versions, or between the pipe and the inner rod for coaxial probes, will
cause erroneous level readings and must be prevented. Single lead probes
are preferred in this case.

Foam How well the Rosemount 3300 Series Radar Transmitter measures in foamy

applications depends upon the properties of the foam; light and airy or dense
and heavy, high or low dielectrics, etc. If the foam is conductive and creamy
the transmitter will probably measure the surface of the foam. If the foam is
less conductive the microwaves will probably penetrate the foam and
measure the liquid surface.

Vapor In some applications, as ammonia, there is heavy vapor above the product

surface that will influence the level measurement. The Rosemount 3300
Series Radar Transmitter can be configured to compensate for the influence
of vapor.

Measuring Range The measuring range differs depending on probe type and characteristics of

the application. The values given in Tabl e 2-3 can be used as a guideline for
clean liquids.

• Media with higher dielectric constant (ε
allows a longer measuring range.

• A calm surface gives better reflection than a turbulent surface. For a
turbulent surface the measuring range might be reduced.

• Surface foam and particles in the tank atmosphere are also
circumstances that might affect measuring performance.

Interface Model 3302 is the ideal choice for measuring the interface of oil and water or

other liquids with significant dielectric differences. It is also possible to
measure interface with the Model 3301 in bridle/tank applications when the
probe is fully immersed in the liquid.

Figure 2-6. Fully immersed
probe

Upper product

Lower product

BRIDLE_INTERFACE

Rigid twin lead, flexible twin lead and coaxial probes can be used to measure
interfaces. However, the coaxial probe is the preferred choice. For measuring
the interface level, the transmitter uses the residual wave of the first reflection.
Part of the wave, which was not reflected at the upper product surface,
continues until it is reflected at the lower product surface. The speed of this
wave depends fully on the dielectric constant of the upper product.

2-9

Rosemount 3300 Series

If interface is to be measured, the following criteria have to be fulfilled:

• The dielectric constant of the upper product must be known. The Radar

• The dielectric constant of the upper product must have lower dielectric

• The difference between the dielectric constants for the two products

• Maximum dielectric constant for the upper product is 10 for the coaxial

• The upper product thickness must be larger than 8 inch (0.2 m) for the

The maximum allowable upper product thickness/measuring range is
primarily determined by the dielectric constants of the two liquids.

Target applications include interfaces between oil/oil-like and water/water-like
liquids. For such applications the upper product dielectric constant is low (<3)
and the lower product dielectric constant is high (>20), and the maximum
measuring range is only limited by the length of the coaxial and rigid twin lead
probes.

(65 ft/20 m), can be gained from Figure 2-7 on page 2-10..

VESSEL CHARACTERISTICS

Heating Coils, Agitators The Rosemount 3300 Series Radar Transmitter is relatively insensitive to

objects in the tank since the radar signal is transmitted along a probe.

Avoid physical contact between probes and agitators as well as applications
with strong fluid movement unless the probe is anchored. If the probe can
move within 1 ft (30 cm) away from any object, such as an agitator, during
operation then probe tie-down is recommended.

In order to stabilize the probe for side forces, it is possible to hang a weight at
the probe end (flexible probes only) or fix/guide the probe to the tank bottom.

Tank Sha pe The guided wave radar transmitter is insensitive to the tank shape. Since the

radar signal travels along a probe, the shape of the tank bottom has virtually
no effect on the measurement performance. The transmitter handles flat or
dish-bottom tanks equally well.

The transmitter can be mounted in nozzles by using an appropriate flange. It
is recommended that the nozzle size is within the dimensions given in
Table 3-4. For small nozzles it may be necessary to increase the Upper Null
Zone (UNZ) in order to reduce the measuring range in the upper part of the
tank. By setting the UNZ equal to the nozzle height, the impact on the
measurement due to interfering echoes from the nozzle will be reduced to a
minimum. See also section “Disturbances at the Top of the Tank“ on
page 6-12. Amplitude Threshold adjustments may also be needed in this
case.

ELECTRICAL INSTALLATION

Cable/conduit entries The electronics housing has two entries for ½ - 14 NPT. Optional M20×1.5

and PG 13.5 adapters are also available. The connections are made in
accordance with local or plant electrical codes.

Make sure that unused ports are properly sealed to prevent moisture or other
contamination from entering the terminal block compartment of the electronics
housing.

NOTE!

Use the enclosed metal plug to seal the unused port.

Grounding The housing should always be grounded in accordance with national and

local electrical codes. Failure to do so may impair the protection provided by
the equipment. The most effective grounding method is direct connection to
earth ground with minimal impedance. There are two grounding screw
connections provided. One is inside the Field Terminal side of the housing
and the other is located on top of the housing. The internal ground screw is
identified by a ground symbol: .

NOTE!

Grounding the transmitter via threaded conduit connection may not provide
sufficient ground.

NOTE!

In the Explosionproof/Flameproof version the electronics is grounded via the
transmitter housing. After installation and commissioning make sure that no
ground currents exist due to high ground potential differences in the
installation.
Grounding (+) will cause faulty operation but does not cause permanent
damage.

Cable Selection Use shielded twisted pair wiring for the Rosemount 3300 Series in order to

comply with EMC regulations. The cables must be suitable for the supply
voltage and approved for use in hazardous areas, where applicable. For
instance, in the U.S., explosion-proof conduits must be used in the vicinity of
the vessel. For the ATEX flame proof approval version of the 3300 Series,
suitable conduits with sealing device or flame proof (EEx d) cable glands must
be used depending on local requirements.

Use 18 AWG to 12 AWG in order to minimize the voltage drop to the
transmitter.

Hazardous Areas When the 3300 transmitter is installed in hazardous area, local regulations

and specifications in applicable certificates must be observed.

CONFIGURATION PARAMETERS

The Model 3301 transmitter can be configured for level and volume
measurements. The Model 3302 is designed to measure interface level and
interface distance as well.

The Rosemount 3300 transmitter can be pre-configured according to the
ordering specifications in the Configuration Data Sheet.

Basic Configuration The basic transmitter configuration includes setting the tank geometry

parameters. For interface measurements the dielectric constant of the top
liquid must also be given. For some applications with heavy vapor, the vapor
dielectric must be given as well.

Reference Gauge Height

The Reference Gauge Height is the distance from the Upper Reference Point
to the bottom of the tank. The transmitter measures the distance to the
product surface and subtracts this value from the Reference Gauge Height to
determine the level.

Probe Length

The probe length is the distance between the Upper Reference Point and the
end of the probe. If a weight is used at the end of the probe it shall not be
included.

This parameter is pre-configured at factory. It must be changed if the probe is
shortened.

Probe Type

The transmitter is designed to optimize measurement performance for each
probe type.

This parameter is pre-configured at factory. This value needs to be changed if
the probe type is changed.

Flexible and Rigid probes require different radar electronics and can not be
used with the same transmitter head.

Dielectric Constant of Upper Product

For interface measurements the dielectric constant of the upper product is
essential in order to obtain good accuracy. See section “Interface” on
page 2-9 for further information on dielectric constants.

If the dielectric constant of the lower product is significantly smaller than the
dielectric constant of water, you may need to make special adjustments. See
section “Interface Measurements for Semi-Transparent Bottom Products” on
page 6-5 for further information.

For level measurements the Upper Product Dielectric parameter corresponds
to the actual dielectric constant of the product in the tank. Normally this
parameter does not need to be changed even if the actual dielectric constant
of the product deviates from the Upper Product Dielectric parameter value.
However, for some products measurement performance can be optimized by
setting the proper product dielectric constant.

Dielectric Constant of Vapor

In some applications there is heavy vapor above the product surface having a
significant influence on the level measurement. In such cases the vapor
dielectric can be entered to compensate for this effect.

The default value is equal to 1 which corresponds to the dielectricity of
vacuum. Normally this value does not need to be changed since the effect on
measurement performance is very small for most vapors.

Upper Null Zone

This parameter should only be changed if there are measurement problems in
the upper part of the tank. Such problems may occur if there are disturbing
objects close to the probe. By setting the Upper Null Zone the measuring
range is reduced. See Section 6: Disturbances at the top of the tank for
further information.

Rosemount 3300 Series

4 mA point

The 4 mA point should be set above the Lower Dead Zone (see Section 2:
Dead Zones). If the 4 mA point is set to a point within the Dead Zone or below

the probe end, the full range of the analog output is not used.

20 mA point

Make sure that the 20 mA point is below the Upper Null Zone.

The 20 mA point should be set below the Upper Dead Zone (see “Dead
Zones” on page 2-7). If the 20 mA point is set to a point within the Dead Zone
the full range of the analog output is not used.

Probe angle

If the transmitter is not mounted vertically the angle from vertical position must
be given.

• Vertical Cylinder

• Horizontal Cylinder

• Vertical Bullet

• Horizontal Bullet

Strapping Table

Use a strapping table if a standard tank type does not provide sufficient
accuracy. Use most of the strapping points in regions where the tank shape is
non-linear. A maximum of 10 points can be added to the strapping table.

Figure 4-3. Strapping points

Actual tank bottom may look like this.

Using only 3 strapping points results in a level-to-volume profile
that is more angular than the actual shape.

Using 6 of the points at the bottom of the tank yields a
level-to-volume profile that is similar to the actual tank bottom.

Rosemount 3300 Series

BASIC CONFIGURATION This section describes the various HART commands used to configure the

3300 Series of transmitters for level measurements. The transmitter outputs a
4 - 20 mA signal proportional to the primary variable. Three additional
variables are available through the HART signal.

Transmitter Variables

HART Comm

1, ,1 ,1, 1

Transmitter Units

HART Comm

1, 3, 2

Reference Gauge Height

HART Comm

1, 3, 4

You may assign up to four transmitter variables. Typically, the primary variable
(PV) is configured to be Aggregate Level, Interface Level or Volume.

For the model 3301 the primary variable is typically set to be Level. If the
transmitter is in the Immerse Probe mode (see section “Measurement Mode” )
the PV is normally set to Interface Level.

For the model 3302 the PV is typically set to Interface Level, but Level and
other options may also be used.

Set transmitter units for level and temperature.

The Reference Gauge Height is the distance from the Upper Reference Point
to the bottom of the tank (see Figure 4-1 on page 4-2). When setting the
Reference Gauge Height, keep in mind that this value is used for all level
measurements performed by the 3300 Series transmitter.

The Reference Gauge Height must be set in linear (level) units, such as feet
or meters, regardless of primary variable assignment.

Probe Length

HART Comm

1, 3, 5

The probe length is the distance from the Upper Reference Point to the end of
the probe, see Figure 4-1. If the probe is anchored to a weight do not include
the height of the weight. This parameter is pre-configured at factory. The
Probe Length needs to be changed if for example the probe is shortened.

The transmitter automatically makes an initial calibration based on the type of
probe that is used. This parameter is pre-configured at factory and only needs
to be set if the probe is changed to another type. Choose one of the following
options:

• Rigid Twin Lead

• Flexible Twin Lead

•Coaxial

• Rigid Single Lead

• Flexible Single Lead

NOTE

Flexible and Rigid probes require different radar electronics and can not be
used with the same transmitter head.

For interface measurements the dielectric constant of the upper product is
essential for calculating the interface level and the upper product thickness.
By default the Product Dielectric parameter is about 2.

If the dielectric constant of the lower product is significantly smaller than the
dielectric constant of water, you may need to make special adjustments. See
section “Interface Measurements for Semi-Transparent Bottom Products” on
page 6-5 for further information.The dielectric constant of the product is used
for setting the appropriate signal amplitude thresholds, see Section 6: Service
and Troubleshooting for more information on amplitude threshold settings.
Normally this parameter does not need to be changed for level
measurements. However, for some products measurement performance can
be optimized by setting the proper product dielectric constant.

Vapor Dielectric

HART Comm

4-10

1, 3, 7

The Rosemount Configuration Tool (RCT) software includes a Dielectric Chart
wich lists the dielectric constants of a wide range of products. RCT also
includes a tool which allows you to calculate dielectric constants based on
measurements of the Upper Product Thickness.

In some applications there is heavy vapor above the product surface having a
significant influence on the level measurement. In such cases the vapor
dielectric can be entered to compensate for this effect.

The default value is equal to 1 which corresponds to the dielectric constant of
vacuum. Normally this value does not to be changed since the effect on
measurement performance is very small for most vapors.

immersed in liquid. In this mode the transmitter ignores the upper product
level. See Section 6: Interface measurements with fully immersed probes for
more information.

NOTE!

Only use Interface Immersed Probe for applications where interface is
measured for a fully immersed probe.

Enter the angle between the probe and the vertical line. The default value is
equal to zero. Do not change this value if the transmitter is mounted with the
probe along the vertical line (which is normally the case).

For interface measurements the Maximum Upper Product Thickness
parameter may be used in special cases when the dielectric constant of the
upper product is relatively high. By setting this parameter you can avoid that
interface measurements are getting out of range.

The default Damping value is 10. Normally this value does not need to be
changed. The Damping parameter determines how quickly the transmitter
responds to level changes and how robust the measurement signal is against
noise. See “High Level Rates” on page 6-7 for more information.

RCT-SETUP_OUTPUT

Typically, the Primary Variable (PV) is configured to be Product Level,
Interface Level or Volume.

Other variables like Product Distance, Interface Distance, Upper Product
Thickness, etc. are available as well.

For model 3301 the primary variable is typically set to be Level. If the
transmitter is in the Immersed Probe mode (see section
“Measurement Mode” ) the PV is normally set to Interface Level.

For the model 3302 the PV is typically set to Interface Level, but Level and
other options may also be used.

Set the Lower Range Value (4 mA) and the Upper Range Value (20 mA) to
the desired values. Keep in mind that the 20 mA value should be below the
Upper Dead Zone, and the 4 mA point should be above the Lower Dead Zone
if you want to use the full 4-20 mA range within the measuring range of the
transmitter.

Also make sure that the 20 mA value is set below the Upper Null Zone (UNZ).
(the UNZ parameter may be used if there are measurement problems in the
upper part of the tank, see Section 6: Disturbances at the top of the tank). The
UNZ is equal to zero in the default configuration.

See Section 2: Dead Zones for more information on Upper and Lower Dead
Zones.

See Section 4: Basic Configuration for more information on setting the Upper
and Lower Range values.

The default Damping value is 10. Normally this value does not need to be
changed. The Damping parameter may be changed if there are high filling
rates, see “High Level Rates” on page 6-7 for more information.

The Reference Gauge Height is the distance from the Upper Reference
Point to the bottom of the tank (see Figure 4-1 on page 4-2). When setting the
Reference Gauge Height, keep in mind that this value is used for all level and
volume measurements performed by the 3300 transmitter.

The Reference Gauge Height must be set in linear (level) units, such as feet
or meters, regardless of primary variable assignment.

The Upper Null Zone (UNZ) should not be changed unless there are
disturbances at the top of the tank. By increasing the Upper Null Zone value
measurements in this region can be avoided. See Section 6: Disturbances at
the top of the tank for more information on how to use the UNZ. The UNZ is
equal to zero in the factory configuration.

Probe

The 3300 Series transmitter automatically makes some initial calibrations
based on the chosen Probe Type. The following Probe Types are available:

• Twin Lead

• Flexible Twin Lead

•Coaxial

• Rigid Single Lead

• Flexible Single Lead

NOTE

Flexible and Rigid probes require different radar electronics and can not be
used with the same transmitter head

4-20

The Probe Length is the distance from the Upper Reference Point to the end
of the probe, see Figure 4-1. If the probe is anchored to a weight do not
include the height of the weight.

The Probe Angle is the angle between the probe and the vertical line. Set
this value equal to zero if the transmitter is mounted with the probe along the
vertical line (which is normally the case).

Normally the Measurement Mode does not need to be changed. The
transmitter is pre-configured according to the specified model:

Table 4-2. Measurement Mode

Model Measurement Mode

3301 Level
3302 Level, Level and Interface

(1) Default setting

Interface Immersed Probe is used for applications where the probe is fully

immersed in liquid. In this mode the transmitter ignores the upper product
level. See “Section 6: Interface measurements with fully immersed probes” for
more information.

NOTE!

Only use Interface Immersed Probe for applications where interface is
measured for a fully immersed probe.

Dielectrics

(1)

, Interface Immersed probe

(1)

, Interface Immersed probe

In some applications there is heavy vapor above the product surface having a
significant influence on the level measurement. In such cases the Vapor
Dielectric can be entered to compensate for this effect.

The default value is equal to 1 which corresponds to the dielectric constant of
vacuum. Normally this value does not need to be changed since the effect on
measurement performance is very small for most vapors.

For interface measurements the dielectric constant of the upper product is
essential for calculating interface level and the upper product thickness. By
default the Upper Product Dielectric parameter is about 2.

If the dielectric constant of the lower product is significantly smaller than the
dielectric constant of water, you may need to make special adjustments. See
section “Interface Measurements for Semi-Transparent Bottom Products” on
page 6-5 for further information.

The dielectric constant of the product is used for setting the appropriate signal
amplitude thresholds, see Section 6: Service and Troubleshooting for more
information on amplitude threshold settings. Normally this parameter does not
need to be changed for level measurements. However, for some products
measurement performance can be optimized by setting the proper product
dielectric constant.

RCT contains tools to estimate the dielectric constant of the current product:

•The Dielectric Chart lists the dielectric constant of a large number of

products. Use one of the two following methods to view the Dielectric
Chart:

- Choose the View>Dielectric>Dielectric Chart menu option.

- Click the Dielectric Chart icon in the Project Bar Advanced section.

•The Dielectric Calculator lets you calculate the dielectric constant of

the Upper Product based on the following input:

- actual upper product thickness,

- the dielectric constant value stored in the transmitter, and

- the upper product thickness presented by the transmitter.

Plotting the measurement signal

Figure 6-2. Waveform plot in RCT

The Radar Configuration Tool (RCT) has powerful tools for advanced
troubleshooting. By using the Waveform Plot function you get an instant view
of the tank signal. Measurement problems can be solved by studying the
position and amplitude of the different pulses.

To plot the measurement signal:

1. Start the Radar Configuration Tool program.

2. Choose the View>Plotting menu option, or choose the Plotting icon in
the RCT workspace (Advanced page at the left side of the workspace)
and click the Read button.

Upper Null Zone

WAVEFORMPLOT_GENERAL

In a typical measurement situation the following pulses appear in the diagram:

P1 - Reference pulse. This pulse is caused by the transition between
transmitter head and probe. It is used by the transmitter as a reference at
level measurements.

P2 - Product surface. This pulse is caused by a reflection on the product
surface. In Measurement Mode=Interface when Immersed Probe however, P2
indicates the interface since the surface of the upper product is ignored.

P3 - Interface or probe end. This pulse is caused by reflection on the interface
between an upper product and a bottom product with a relatively high
dielectric constant. It may also be caused by the probe end if there is no
product above. This pulse is shown when the transmitter is in Measurement
Mode=Level & Interface.

Different amplitude thresholds are used in order to filter out unwanted signals.
The following amplitude thresholds are used for the 3300 transmitter:

T1 - amplitude threshold for detection of the Reference pulse P1.

T2 - amplitude threshold for detection of the product level peak P2.

T3 - amplitude threshold for detection of the interface level peak P3.

T4 - amplitude threshold that is used to detect whether the probe is fully

immersed in the upper product or not.

Normally the thresholds are adjusted to approximately 50% of the signal peak
amplitdue. To adjust the Amplitude Thresholds open the Advanced section
in the RCT Project Bar and choose Device Commands>Details>Set Nominal
Thresholds.

Interface Measurements for Semi-Transparent Bottom Products

In interface applications where the bottom product has a low dielectric
constant, or if the signal is attenuated in the upper product, the amplitude of
the reflected signal is relatively low and difficult for the transmitter to detect. In
such a case it may be possible to detect the reflected signal if the
corresponding amplitude threshold is adjusted.

The Radar Configuration Tool (RCT) lets you view a waveform plot to analyze
the measurement signal. The plot shows the signal and the thresholds used
for the different amplitude peaks. By adjusting amplitude threshold T3 it is
possible to detect even weak interface signals.

Guidelines for amplitude threshold settings:

• The amplitude threshold T3 should be approximately 50 % of the
interface signal amplitude.

• Threshold T3 should not be less than 3.

• If possible, T3 should be higher than T2.

You can use the RCT software or a HART 275 Communicator to change the
amplitude thresholds. For the HART Communicator use the HART command
[1, 4, 6, 2]. See also “Amplitude Threshold Settings” on page 6-14.

RCT lets you view a plot of the measurement signal along with the current
thresholds:

1. From the View menu choose the Plotting option, or double-click the

Plotting icon in the Advanced section of the RCT Project Bar.

2. Click the Read button .

3. To adjust the Amplitude Thresholds open the Advanced section in the

RCT Project Bar and choose Device Commands>Details>Set Nominal
Thresholds.

Rosemount 3300 Series

High Level Rates The measurement signal is filtered in order to minimize the influence of

disturbing noise. In most measurement situations this has no noticeable effect
on the response time to level changes. If high level rates occur it may
however be necessary to reduce the damping value in order to allow the
transmitter to respond quicker. If there is too much noise the damping value
may be increased in order to get a stable measurement signal.

You can use the RCT software or a HART 275 Communicator to change the
Damping value. For the HART Communicator use the key sequence
[1, 4, 4, 4].

In the RCT software open the Setup>Output tab and enter the desired
Damping value:

Output tab

Damping

SETUP_OUTPUT

The Damping parameter determines how quickly the transmitter responds to
level changes and how robust the measurement signal is against noise.
Technically, a damping value of 10 means that in 10 seconds the output from
the transmitter is about 63% of the new level value. Consequently, when there
are rapid level changes in the tank, it may be necessary to decrease the
Damping value for the transmitter to be able to track the surface. On the other
hand, in noisy environments, and if level rates are low, it may be better to
increase the damping value to have a stable output signal.

Interface measurements with fully immersed probes

The 3300 series has a measurement option which makes it possible to handle
interface measurements when the product level is not visible, for example in a
full bridle pipe as illustrated in Figure 6-6. In this case the probe is fully
immersed into the upper product, and only the interface level is detected by
the transmitter. Even if the upper product level drops, it is ignored by the
transmitter which continues to measure only the interface level, but the
measurement accuracy is reduced since the transmitter does not take into
account the influence of the air gap above the product surface.

The Measurement Mode parameter is available via the
HART command [1, 3, 9]. Choose the Interface when Immersed Probe option.

Measurement mode Interface when Immersed Probe can also be activated in
the RCT software:

1. Open the Setup window.

2. Select the Tank Config tab.

3. Choose Measurement Mode Interface when Immersed Probe.

4. Click the Send Page button.

NOTE!

Do not use Measurement Mode Interface when Immersed Probe in “standard”
applications when both Interface Level and Product Level are measured.

If the product level drops, the air filled region in the upper part of the pipe will
slightly reduce the measurement accuracy of the interface level. To achieve
high accuracy in this measuement mode the probe must be fully immersed.

Level and Distance Calibration

When calibrating the transmitter it is important that the product surface is calm
and that the tank is not being filled or emptied.

A complete calibration is performed in two steps:

1. Calibrate the Distance measurement by adjusting the Calibration Offset
parameter.

2. Calibrate the Level measurement by adjusting the Reference Gauge
Height.

Distance calibration

1. Measure the actual distance between the Upper Reference Point and the
product surface.

2. Adjust the Calibration Offset so that the Distance measured by the
transmitter corresponds to the actual distance.
The Calibration Offset parameter is available via
HART command [1, 4, 6, 4],
or,

Disturbances at the Top of the Tank

Using the Trim Near Zone Function

For transmitters using the Guided Wave Radar technology the performance In
the Near Zone (referred to as the region between 0-1.6 ft (0-0.5 m) below the
Upper Reference Point) is normally somewhat limited. However, the 3300
transmitter is equipped with software functionality that minimizes the Upper
Dead Zone. The factory setting is normally sufficient and doesn’t need to be
repeated after installation.

However, since the setting is optimized depending on actual installation,
further trimming may be necessary in the case of unfavourable conditions.
This may for example be the case if a Single Lead probe is mounted in a
small nozzle, or if there are disturbing obstacles in the Near Zone. The
trimming means that the measurement performance in the Near Zone is
maintained even under these conditions and prevents false echo indication.

To trim the Near Zone perfomance do the following:

1. Make sure that the product level is below the Near Zone region
(0-1.6 ft (0-0.5 m) below the Upper Reference Point).

2. Start the Radar Configuration Tools (RCT).

3. Choose the Device Commands option from the View menu.

4. Open the Details folder.

5. Click the Trim Near Zone option.

6. Select the Update option and click the OK button.

To reset the transmitter to factory settings do the following:

1. Start the Radar Configuration Tools (RCT).

2. Choose the Device Commands option from the View menu.

3. Open the Details folder.

4. Click the Trim Near Zone option.

5. Select the Reset to Factory Settings option and click the OK button.

Changing the Upper Null Zone

If there are measurement problems in the upper part of the tank you may use
the Trim Near Zone function as described above.

However, if the desired measurement range is below the Near Zone, or if
disturbing objects are located below the Near Zone, the Upper Null Zone
parameter can be used to avoid measurements above a specific level.

To set the Upper Null Zone do one of the following:

1. Select the HART command [1, 4, 4, 5].

2. Enter the desired value,

Amplitude Threshold Settings

Figure 6-10. Example 1:
amplitude threshold T2 is too
high.

The amplitude thresholds are automatically adjusted to appropriate values in
order to filter out noise and other non-valid measurements from the
measurement signal.

The amplitude of the measurement signal, i.e. the amplitude of the signal that
is reflected by the product surface, is related to the actual dielectric constant
of the product. The amplitude threshold that is used by the transmitter is
based on the parameter configuration of the current product dielectric
constant (see Section 4: Basic Configuration). Normally no other threshold
adjustment is needed, but if the transmitter still does not track the product
surface correctly it may be necessary to adjust the threshold values.

The Radar Configuration Tool (RCT) has a plot function allowing you to view
the reflections along the probe.

If the amplitude threshold is too high the product level is not detected as
illustrated in Figure 6-10.

If there are disturbing objects in the tank the threshold must be carefully set in
order to avoid locking on the wrong amplitude peak. In Figure 6-11 the
transmitter has locked on a peak above the actual product surface, i.e. a
disturbance was interpreted as the product surface, whereas the actual
product surface was interpreted as an interface or the probe end.
