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 r eflected 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 T ransmitter 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:

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 possib le to convert the HAR T 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 Ros em o un t 75 1 Fi eld Signal Indicator or it can be equipped with an integral display.

The transmitter can easily be configured by using a Field Communicator or a PC with the Radar Configuration Tool software. Rosemount 3300 Series transmitters are also compatible with the AMS Suite software which also can be used for configuration.

For HART communication a minimum load resistance of 250 Ohm within the loop is required.

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 adva nced signa l 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:

Table 2-3. Probe type guide for different product viscosity

Coating not recommended Thin coating allowed, but no

(1) Consult factory if agitation/turbulence and high viscous products. (2) HTHP and HP single probes should be used with precaution in viscous or crystallizing media. Cooling

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

bridging

of high temperature vapor in the upper part of the probe may lead to condensation and deposition that blocks the measurement signal.

(1)(2)

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. If a Twin Lead probe is required, regular cleaning may be necessary.

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.

The maximum measuring range differs depending on application according to:

• Disturbing objects close to the probe.

• Media with higher dielectric constant (ε

) gives better reflection and

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.

• Coating/contamination can reduce the measuring range.

• Disturbing EMC environment in tank.

Interface Rosemount 3302 is the ideal choice for measuring the interface of oil and

water, or other liqui ds with significant dielectric differences. It is also possible to measure interface with a Rosemount 3301 in applications where the prob e is fully immersed in the liquid.

Figure 2-6. Interface measurement with a Rosemount 3302 and a Rosemount 3301 (fully immersed probe).

Coaxial, Rigid twin, Flexible twin and Rigid Single lead probes can be used for measuring interfaces. The coaxial probe is the preferred choice for clean liquids and when the bridle is not fully immersed. In applications with a fully immersed probe, the twin lead probes are recommended for nozzle installations, and the rigid single lead probe is best for bridle mounting.

Rosemount 3300 Series

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.

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

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

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

• The difference between the dielectric constants for the two products

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

Figure 2-7. Reduction of maximum measuring range for Flexible Twin Lead probe

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.

For the flexible twin lead probe, the reduction of maximum measuring range (65 ft/20 m), can be gained from Figure 2-7 on page 2-10.

However, chara cteristics varies widely between different applications. For other product combinations, consult factory.

Emulsion Layers

Sometimes there is an emulsion layer (mix of the products) between the two products which, depending on its characteristics, will affect interface measurements.

Please consult factory for guidelines on how to handle emulsion layers.

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 Shape 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.

SAFETY MESSAGES Procedures and instructions in this section may require special precautions to

ensure the safety of the personnel performing the operations. Information that raises potential safety issues is indicated by a warning symbol ( ). Please refer to the following safety messages before performing an operation preceded by this symbol.

Explosions could result in death or serious injury:

Verify that the operating environment of the transmitter is consistent with the appropriate hazardous locations certifications.

Before connecting a HART-based communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.

Do not remove the gauge cover in explosive atmospheres when the circuit is alive.

Failure to follow safe installation and servicing guidelines could result in death or serious injury:

Make sure only qualified personnel perform the installation. Use the equipment only as specified in this manual. Failure to do so may impair the

protection provided by the equipment. Do not perform any service other than those contained in this manual unless you are

qualified.

Process leaks could result in death or serious injury.

Make sure that the transmitter is handled carefully. If the Process Seal is damaged, gas might escape from the tank if the transmitter head is removed from the probe.

Rosemount 3300 Series

High voltage that may be present on leads could cause electrical shock:

Avoid contact with leads and terminals. Make sure the main power to the 3300 transmitter is off and the lines to any other

external power source are disconnected or not powered while wiring the gauge. Probes covered with plastic and/or with plastic discs may generate an ignition-capable

level of electrostatic charge under certain extreme conditions. Therefore, when the probe is used in a potentially explosive atmosphere, appropriate measures must be taken to prevent electrostatic discharge.

The transmitter can be mounted in nozzles by using an appropr iate 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 6-11. 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 comp artment 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 Explosion-proof/Flame-proof version the electron ics 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.

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

The 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.

00809-0100-4811, Rev CA February 2006

Rosemount 3300 Series

Reference Gauge Height

The Reference Gauge Height is the distance from th e Upper Refer ence Point to the bottom of the tank. The transmitter measures the dis tance 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 betwee n 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.

For Flexible Single Lead probes anchored with clamps, the probe length should be configured as the distance between the underside of the flange and the upper clamp (see “Anchoring” on page 3-18).

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 factor y. 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.

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 so me 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 prod uct 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 th e die lectricity of vacuum. Normally this value does not need to be changed since the effect on measurement performance is very small for most vapors.

4-3

Page 56

Rosemount 3300 Series

Upper Null Zone

This parameter should only be chang ed if there are measuremen t 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.

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.

Strapping Table

Use a strapping table if a standard tank type does not provide sufficient accuracy . Use most o f the strapp ing point s in region s where th e ta nk 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 co nfigure the

3300 Series of transmitters for level measurements. The transm itter 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

Measurement Units

HART Comm

1, 3, 1

Reference Gauge Height

HART Comm

1, 3, 2, 1

Y ou may assign up to fou r transmitter variables. T yp ically, 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 th e Upper Refer ence 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, 2, 2

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.

HART Comm

Product Dielectric

HART Comm

1, 3, 3, 3

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 fo llowing options:

• Rigid Twin

• Flexible Twin

• Coaxial, Coaxial HP, Coaxial HTHP

• Rigid Single, Rigid Single HTHP, Rigid Single PTFE

• Flexible Single, Flexible Single HTHP, Flexible Single PTFE

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: Ser vice 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.

Va por Dielectric

HART Comm

1, 3, 3, 2

The Rosemount Configuration Tool (RCT) software includes a Dielectric Chart which 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.

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.

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 Immer sed 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).

Maximum Upper Product Thickness

HART Comm

1, 4, 5, 2

Damping

HART Comm

1, 3, 5

Display Panel

HART Comm

1, 4, 2

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.

Choose which variables to be displayed and the desired language to be u sed. The display toggles between the selected variables every two seconds.

When setting the range values, it is possible to enter the values directly using the keypad on the Field Communicator, or you may use actual values (HART command [1, 3, 4, 2]). Keep in mind that the 20 mA value should be below the Upper Dead Zone. If the 20 mA point is set to a point within the Dead Zone the full range of the analog output is not used.

Also make sure that the 20 mA value is below the Upper Null Zone (UNZ). (This 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.

The 4 mA point should be above the Lower Dead Zone. If the 4 mA point is set to a point within the Dead Zone or below the probe end (tank bottom for example), the full range of the analog output is not used.

Figure 4-15. Setup output tab

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 the Rosemount 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 Rosemount 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.

Tank Geometry

The Reference Gauge Height is the distance from the Upper Reference Point to the bottom of the tank (see Figure 4-1 on page4-2). 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:

• Rigid Twin

• Flexible Twin

• Coaxial, Coaxial HP, Coaxial HTHP

• Rigid Single, Rigid Single HTHP, Rigid Single PTFE

• Flexible Single, Flexible Single HTHP, Flexible Single PTFE

NOTE

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

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

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.

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 pa rameter 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.

SAFETY MESSAGES Procedures and instructions in this section may require special precautions to

Explosions could result in death or serious injury.

Verify that the operating environment of the gauge is consistent with the appropriate hazardous locations certifications.

Do not remove the gauge cover in explosive atmospheres when the circuit is alive.

Failure to follow safe installation and servicing guidelines could result in death or serious injury.

Make sure only qualified personnel perform the installation. Use the equipment only as specified in this manual. Failure to do so may impair the

protection provided by the equipment. Do not perform any service other than those contained in this manual unless you are

qualified.

High voltage that may be present on leads could cause electrical shock.

Avoid contact with leads and terminals. Make sure the main power to the Rosemount 3300 Transmitter is off and the lines to any

other external power source are disconnected or not powered while wiring the gauge.

Probes covered with plastic and/or with plastic discs may generate an ignition-capable level of electrostatic charge under certain extreme conditions. Therefore, when the probe is used in a potentially explosive atmosphere, appropriate measures must be taken to prevent electrostatic discharge.

Process leaks could result in death or serious injury.

Make sure that the transmitter is handled carefully. If the Process Seal is damaged, gas might escape from the tank if the transmitter head is removed from the probe.

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

In a typical measurement situation the following pulses app ear in the dia gram: 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 th e 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 33 0 0 tran s m itte r:

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.

WAVEFORMPLOT_GENERAL

Normally the thresholds are adjusted to approximately 50% of the signal peak amplitude. To adjust the Amplitude Thresholds open the Advanced section in the RCT Project Bar and choose Device Commands>Details>Set Nominal Thresholds. To reset the default values set Amplitude Threshold=0 (zero).

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 dif ficult 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 375 Field Communicator to change the amplitude thresholds. For the Field Communicator use the HART command [1, 4, 5, 3]. See also “Amplitude Threshold Settings” on page 6-13.

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.

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

disturbing noise. In most measurement situations this does not have a 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 stab le measurement sign al.

You can use the RCT software or a 375 Field Communicator to change the Damping value. For the HART Communicator use the key sequence [1, 3, 5].

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 tr ansmitter 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. Consequen tly, when there are rapid level changes in the tank, it may be necessary to decr ease 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 han dle 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, 3, 4]. 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 “stand ard” applications when both Interface Level and Product Level are measured.

Figure 6-6. Interface Level measurements in a full bridle pipe.

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 Le ve l measu re m en t by adju stin g the Re fe re nc e Ga ug e 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, 5, 5], or RCT: open the Advanced section in the Project Bar and choose Device Commands>Basics>Set Calibration Offset.

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 reg ion 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 unfavorable 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 indic at i on .

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.

NOTE!

The Trim Near Zone function should only be used for reducing impact from constant disturbances. It is not suitable for occasional disturbances.

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

Measurements are not performed within the Upper Null Zone (UNZ). By setting the UNZ parameter to zero, measurements can be performed in the region close to the flange (Near Zone). However, it is very important that there are no disturbances in that region if UNZ is set to zero.

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

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 certain level.

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.
