2.1 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).

January 2015

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.

2.2 Application examples

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 Rosemount 3300 Series Transmitters suitable for a wide range of applications.

2.3 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

By using the optional HART Tri-Loop 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 Rosemount 751 Field 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 (RCT) software. Rosemount 3300 Series Transmitters are also compatible

with the AMS

2.4 Process characteristics

The Rosemount 3300 Series has 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.

2.4.1 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 select a suitable probe. For detailed information on the maximum recommended viscosity and coating, see Table A-6 on page 131.

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

2.4.2 Bridging

Section 2: Transmitter Overview

January 2015

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, causes 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.

2.4.3 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.

2.4.4 Vapor

In some applications, such 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.

2.4.5 Measuring range

The measuring range differs depending on probe type and characteristics of the application. The values given in Table A-4 on page 128 can be used as a guideline for clean liquids.

The maximum measuring range differs depending on application according to:

 Disturbing objects close to the probe.  Media with higher dielectric constant (

 A calm surface gives better reflection than a turbulent surface. For a turbulent surface,

 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.

2.4.6 Interface

Rosemount 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 a Rosemount 3301 in applications where the probe is fully immersed in the liquid.

Figure 2-3. Interface Measurement with a Rosemount 3302 and a Rosemount 3301 (Fully Immersed Probe)

Reference Manual

00809-0100-4811, Rev DA

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.

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 known. The RCT software has a

built-in dielectric constant calculator to assist users in determining the dielectric constant of the upper product (see “Dielectrics” on page 83).

 The dielectric constant of the upper product must have a lower dielectric constant than

the lower product in order to have a distinct reflection.

 The difference between the dielectric constants for the two products must be larger

than 10.

 The maximum dielectric constant for the upper product is 10 for the coaxial probe, and

5 for twin lead probes.

 The upper product thickness must be larger than 8 in. (0.2 m) for the flexible twin lead

probe, and 4 in. (0.1 m) for the rigid twin lead and coaxial probes in order to distinguish the echoes of the two liquids.

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). 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 2-4 on page 13.

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

2.5 Vessel characteristics

2.5.1 Heating coils, agitators

Transmitter Over view

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.

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.

2.5.2 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.

2.6 Components of the transmitter

The Rosemount 3300 Series Radar Transmitter has an aluminum transmitter housing which contains advanced electronics for signal processing.

The radar electronics produces an electromagnetic pulse which is guided by the probe.

There are different probe types available for various applications: Rigid Twin Lead, Flexible Twin Lead, Rigid Single Lead, Segmented Rigid Single Lead, Flexible Single Lead, and Coaxial.

2.7.1 Transition zones

The measuring range depends on probe type and properties of the product. The upper transition zone is the minimum measurement distance between the upper reference point and the product surface. The upper transition 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 transition zone. The lower transition zone also varies depending on probe type and product.

Figure 2-6 illustrates how the measuring range is related to the transition zones.

00809-0100-4811, Rev DA

For detailed information on transition zones for different probe types, see Tab le A- 4 on

page 128.

Note

Measurement accuracy is reduced in the transition zones. It may even be impossible to make any measurements at all in those regions. Therefore, the 4-20 mA set points must be configured outside the transition zones.

Flange connection on nozzles

Figure 3-3. Mounting in Nozzles

Section 3: Installation

January 2015

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 Ta bl e 3 - 4 . For small nozzles, it may be necessary to increase the Upper Null Zone (UNZ) 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 “Disturbances

at the top of the tank” on page 102. Amplitude Threshold adjustments may also be needed in

this case.

Note

Except for the coaxial probe, the probe must not be in contact with the nozzle.

3.4.2 Installation of single lead probes in non-metallic tanks

For optimal single lead probe performance in non-metallic tanks, the probe must be mounted with a metal flange, or screwed in to a metal sheet (d > 14 in./350 mm) if the threaded version is used.

Figure 3-4. Mounting in Non-Metallic Tanks

Avoid disturbing Electro Magnetic Compatibility (EMC) environment near the tank. Installation in metallic tank is recommended.

3.4.3 Mounting in still pipes/bypass pipes

In order to prevent the probe from contacting the bridle wall when replacing displacers or installing in pipes, centering discs are available for the Rigid Single, Segmented Rigid Single, Flexible Single, and Flexible Twin Lead probes. The disc is attached to the end of the probe and thus keeps the probe centered in the bridle. The discs are available in stainless steel, Alloy C-276,

Alloy 400, and PTFE. See also “Mounting a centering disc for pipe installations” on page 49.

Note

It is not recommended that flexible probes are installed in bypass pipes.

4.2 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 Rosemount 3300 Series Transmitters can be pre-configured according to the ordering specifications in the Configuration Data Sheet.

4.2.1 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.

Figure 4-1. Tank Geometry

Reference Manual

00809-0100-4811, Rev DA

For the different tank connections, the upper reference point is located at the underside of the threaded adapter or at the underside of the welded flange, as illustrated in Figure 4-2:

Figure 4-2. Upper Reference Point

Basic Configuration/Start-Up

Page 73

Reference Manual

00809-0100-4811, Rev DA

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 should 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 Using a segmented

probe on page 36).

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.

Section 4: Basic Configuration/Start-Up

January 2015

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 cannot be used with the same transmitter head.

Dielectric constant of upper product

For interface measurements, the dielectric constant of the upper product is essential to obtain good accuracy. See Interface on page 12 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 Interface measurements for

semi-transparent bottom products on page 96 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.

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 (UNZ), the measuring range is reduced. See Disturbances at the top of the

tank on page 102 for further information.

Note

Measurements are not performed within the UNZ.

4 mA point

The 4 mA point must be set above the lower transition zone (see Transition zones on page 16). If the 4 mA point is set to a point within the transition zone or below the probe end, the full range of the analog output is not used.

20 mA point

Make sure the 20 mA point is below the upper null zone.

Reference Manual

00809-0100-4811, Rev DA

The 20 mA point must be set below the upper transition zone (see Transition zones on

page 16). If the 20 mA point is set to a point within the transition zone, the full range of the

analog output is not used.

Probe angle

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

4.2.2 Volume configuration

For volume calculations, you can select one of the standard tank shapes or the strapping option. Select None if volume calculation is not used.

Tank type

You can select one of the following options:

 Strap table  Vertical cylinder  Horizontal cylinder  Vertical bullet  Horizontal bullet

 Sphere  None

Reference Manual

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.

00809-0100-4811, Rev DA

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.

4.4.1 Transmitter variables

HART Comm

You can assign up to four transmitter variables. Typically, the Primary Variable (PV) is configured to be Aggregate Level, Interface Level, or Volume.

1, 1, 1, 1

For Rosemount 3301, the PV is typically set to be Level. If the transmitter is in the Immerse Probe mode (see Measurement mode on page 71), the PV is normally set to Interface Level.

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

HART Comm

1, 3, 1

Set transmitter units for level and temperature.

4.4.3 Reference gauge height

HART Comm

The Reference Gauge Height is the distance from the Upper Reference Point to the bottom of the tank (see Figure 4-1 on page 62). When setting the Reference Gauge Height, keep in mind that this value is used for all level measurements performed by the Rosemount 3300 Series Tr an sm i tt er.

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

1, 3, 2, 1

4.4.4 Probe length

HART Comm

The probe length is the distance from the Upper Reference Point to the end of the probe, see

Figure 4-1 on page 62. 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.

1, 3, 2, 2

4.4.5 Probe type

HART Comm

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. Select one of the following options:

 Rigid Twin  Flexible Twin  Coaxial  Rigid Single 0.3 in. (8 mm)  Flexible Single  Coaxial HTHP  Coaxial HP/C  Rigid Single HTHP 0.3 in. (8 mm)  Flexible Single HTHP  Rigid Single PTFE  Flexible Single PTFE  Rigid Single HP/C 0.3 in. (8 mm)  Flexible Single HP/C 0.3 in. (8 mm)

Note

Flexible and rigid probes require different radar electronics and cannot be used with the same transmitter head.

4.4.6 Product dielectric

Section 4: Basic Configuration/Start-Up

January 2015

HART Comm

1, 3, 3, 3

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 Interface measurements for

semi-transparent bottom products on page 96 for further information.The dielectric constant

of the product is used for setting the appropriate signal amplitude thresholds, see section

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.

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.

4.4.7 Vapor dielectric

HART Comm

1, 3, 3, 2

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.

4.4.8 Measurement mode

HART Comm

Normally, the measurement mode does not need to be changed. The transmitter is pre-configured according to the specified model:

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).

4.4.10 Maximum upper product thickness

HART Comm

For interface measurements, the Maximum Upper Product Thickness parameter can 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 get out of range.

1, 4, 5, 2

4.4.11 Damping

HART Comm

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 98 for more information.

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 must be below the upper transition zone. If the 20 mA point is set to a point within the Transition Zone, the full range of the analog output is not used.

Make sure the 20 mA value is below the Upper Null Zone (UNZ). (This parameter can be used if there are measurement problems in the upper part of the tank, see Disturbances at the top of

the tank on page 102). The UNZ is equal to zero in the default configuration.

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

See Transition zones on page 16 for more information on the size of upper and lower transition zones.

January 2015

This window also allows you to enter some general information about the transmitter, such as Message, Tag, Descriptor, and Date. This information is not required for the operation of the transmitter and can be left out if desired.

4.6.8 Setup - Output

The Output tab lets you assign up to four transmitter variables.

Reference Manual

00809-0100-4811, Rev DA

Typically, the 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 Rosemount 3301, the PV is typically set to be Level. If the transmitter is in the Immersed Probe mode (see Measurement mode on page 71), the PV is normally set to Interface Level.

For Rosemount 3302, the PV is typically set to be Interface Level, but Level and other options can 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 must be below the upper transition zone, and the 4 mA point must be above the lower transition zone if you want to use the full 4-20 mA range within the measuring range of the transmitter.

Make sure the 20 mA value is set below the Upper Null Zone (UNZ). (The UNZ parameter can be used if there are measurement problems in the upper part of the tank, see Disturbances at the

top of the tank on page 102.) In the default configuration, the UNZ is equal to zero.

See Transition zones on page 16 for more information on upper and lower transition zones.

See Basic configuration on page 69 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

4.6.10 Setup - Geometry

The Geometry tab contains information on reference gauge height, probe length, mounting type, nozzle inner diameter, and nozzle height.

The Reference Gauge Height is the distance from the upper reference point to the bottom of the tank (see Figure 4-1 on page 62). When setting the reference gauge height, keep in mind that this value is used for all level and volume measurements performed by the Rosemount 3300 Series Transmitter.

Reference Manual

00809-0100-4811, Rev DA

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 UNZ value, measurements in this region can be avoided. See

Disturbances at the top of the tank on page 102 for more information on how to use the UNZ.

The UNZ is equal to zero in the factory configuration.

Setup - Environment

The Environment tab contains information about measurement mode, the upper product dielectric constant and advanced environment options.

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

of the following methods to view the dielectric chart:

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

- Select the Dielectric Chart icon in the project bar Advanced section.

 The dielectric calculator allows you to calculate the dielectric constant of the upper

product based on the following input:

4.7.1 Tri-Loop

The Rosemount 333 HART Tri-Loop HART-to-Analog Signal Converter is capable of converting a digital HART burst signal into three additional 4-20 mA analog signals.

To set the Rosemount 3300 Series Transmitter up for the HART Tri-Loop, do the following:

1. Make sure the Rosemount 3300 Series Transmitter is properly configured.

2. If RCT is used for the Rosemount 3300 Series setup, it is recommended that the receive buffer and transfer buffer for the selected COM port are adjusted as described below in section To set the COM port buffers on page 89. Otherwise, Burst Mode cannot be turned off by RCT (for further information on other options for turning off the Burst Mode see To turn off the Burst Mode on page 89).

3. Assign transmitter variables primary variable, secondary variable etc. HART command [1,1,1,1]. RCT: Setup > Output tab.

™

4. Configure variable units: length, volume, and temperature.
