INTRODUCTION This document describes some of the best practices learned during the

installation of thousands of Rosemount Guided Wave Radar level transmitters in upstream oil and gas applications. However, it is not a complete set of instructions; for more detailed information, refer to the respective product manual:

• Rosemount 5300 Series Reference Manual (Document No. 00809-0100-4530)

• Rosemount 3300 Series Reference Manual (Document No. 00809-0100-4811)

The Rosemount 3300 Series and 5300 Series Guided Wave Radar transmitters are Time Domain Reflectometry Pulsed Radar level instruments. They are utilized in the Oil and Gas industry for the measurement of hydrocarbons and water in production and separator tanks. Both the Rosemount 3300 and 5300 Series have the ability to measure overall level as well as interface level in the vessels. They can be installed in several different configurations including flanges, threaded, and side-mounted connections.

The Rosemount 3300 can transmit measurement values and diagnostics with the 4-20 mA HART protocols. The Rosemount 5300 is a high performance transmitter and can transmit measurement values and diagnostics with the 4-20 mA HART and F

OUNDATION™ fieldbus communication protocols.

This document describes which series, models, and probes to use on the various applications within upstream Oil and Gas fields, and therefore serves as a selection guideline specific to these applications and needs. Local restrictions, regulations, or best practices may also apply and should be taken into consideration.

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 gauge 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.

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 / 5300 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.

INTRODUCTION In addition to selecting the appropriate radar level transmitter, mechanical

installation is one of the most critical steps of the commissioning procedure. When done correctly, the subsequent transmitter configuration will be considerably simplified.

The main focus of this section is to provide a framework for installations in a variety of tanks and process connections typically found in the upstream oil and gas industry.

MECHANICAL INSTALLATION

Recommended Mounting Position

Figure 2-1. Mounting Position.

To find an appropriate mounting position for the transmitter, consider the conditions of the tank. The transmitter should be mounted so that turbulence from disturbing objects is reduced. If turbulence is present, the probe may need to be anchored to the bottom.

2-2

Guidelines to be considered when mounting the transmitter:

• Do not mount close to inlet pipes

• If the probe sways because of turbulent conditions in the tank, the probe should be anchored to the tank bottom. In these applications, the best option is anchoring with a Magnet fastened to the weight

• Avoid mounting close to internal objects that are within 6 in. (150 mm) from probe at any time

• The probe should not come into contact with the nozzle or other objects in the tank

NOTE!

Violent fluid movements can cause forces that could break rigid probes.

Rosemount Radar Level Transmitters

Anchoring a Flexible Single Lead probe

A magnet can be fastened to a threaded (M8x14) hole at the end of the weight. Placing a metal plate beneath the magnet, as illustrated in Figure 2-2, will help to guide the probe.

Magnets should not be used on long nozzle applications because the magnet could attach to the side of the nozzle during installation.

Figure 2-3. Anchoring the probe through a welded eye.

The probe rope can also be used for anchoring. The probe rope can be pulled through a suitable anchoring point, e.g. a welded eye and fastened with two clamps. The length from the underside of the flange to the top clamp should be used to configure the probe length.

2-3

Rosemount Radar Level Transmitters

Make sure that the probe does not come into contact with the chamber wall, e.g. by using a centering disk.

A clearance distance of 1 in. (25 mm) between the probe end and the cage bottom is recommended.

Installation in pipes

A centering disk is recommended when installing in pipes to prevent the probe from contacting the chamber wall. The disk is attached to the end of the probe to keep the probe centered in the chamber. The discs are available in stainless steel (SST) and PTFE. The PTFE option is recommended for most applications and the SST centering disk is used for high temperature operations.

Figure 2-4. Improper and proper probe positions.

Reference Manual

00809-0600-4811, Rev AA

February 2009

2-4

To avoid bending the probe (rigid probes) or twisting and coming in contact with the chamber wall (flexible probes), a small clearance distance of 1 in. (25 mm) between the centering disk and chamber bottom is recommended. It should be selected with a dome shaped chamber bottom in mind, which may prevent the centering disk from reaching the bottom.

Side-pipe locations and the effective measurement range are determined by the mating tank connections. There are no constraints on the diameter of the side-pipes, but build-up and clogging should be considered. Also the inlet pipes should not protrude into the chamber since they may interfere with the radar measurement. Always use the same construction material for the chamber and the tank, otherwise, mechanical tensions can arise in the side-connections.

The recommended chamber diameter is 3 in. (75 mm) or 4 in. (100 mm). Chambers with a diameter less than 3 in. (75 mm) may have build-up problems and it may also be difficult to center the probe. Chambers larger than 6 in. (150 mm) can be used, but provide no advantages for the radar measurement.

With the Rosemount 3300 / 5300 Series, single probes are recommended for use in 3 in. (75 mm) and 4 in. (100 mm) chambers. Other probe types are susceptible to build-up and should not be used in this application.

The probe must not touch the chamber wall and should extend the full height of the chamber, but it does not need to touch the bottom of the chamber. Probe type selection depends on the probe length:

Reference Manual

00809-0600-4811, Rev AA February 2009

Rosemount Radar Level Transmitters

Less than 3 ft. (1 m): Use Single Rigid Probe and no centering disk is needed. The transition zones and the height of the weight will limit the use of single flexible probes shorter than 3 ft. (1 m).

Between 3 ft. (1 m) and 10 ft. (3 m): Use either Rigid Single or Flexible Single Probe with the weight and centering disk. Rigid Single has smaller transition zones, while the Flexible Single requires less head-space during installation and is less likely to be damaged.

More than 10 ft. (3 m): Use Flexible Single Probe with a weight and centering disk.

Light hydrocarbon applications not in chambers: Use the Rosemount 5300 Series with either a Rigid Single or Flexible Single Probe. In very light hydrocarbons, the Rosemount 3300 signal loses too much energy on a single probe. The Rosemount 5300 has more efficient and sensitive microwave modules that increase signal strength. The 3300 will, however, work in light hydrocarbon chamber applications, because chambers have similar physics of propagation as the traditional coaxial style probe.

Transition Zones Transition zones, located at the very top and bottom of the probes, are

regions where measurement performance is reduced. Different factors affect the size of the transition zones - probe type, centering disk or no centering disk, and the material and media measured, as shown in Table 2-1.

If a Rosemount 3300/5300 Series Guided Wave Radar with single lead probe is installed in a 10-in. (250 mm) (DN250) high nozzle or larger, there may be resonance and double bounce problems. This can lead to measurement errors for products with low dielectric constants, so 10-in. (250 mm) nozzles or larger should be avoided.

In cases where 10-in. (250 mm) nozzles or larger are used, install an inner steel nozzle with a smaller diameter, as illustrated in Figure 2-7.

Threaded tank connection

Many Oil and Gas applications have 3-in. (75 mm) or 4-in. (100 mm) threaded connections on top of the tank roof.

For this connection, install the Rosemount 3300 / 5300 transmitters with a 1 ½-in. ( 37.5 mm) NPT threaded connection (model code option RA). The probe can be attached to a bushing or adapter piece, reducing the tank opening from a 3-in. (75 mm) or 4 in. (100 mm) threaded connection to the desired 1 ½-in. (37.5 mm) standard Rosemount 3300 / 5300 process connection.

Side mounted process connection

In some cases, tanks might not have top process connections suitable for installation of Guided Wave Radar units, so side mounted process connections are a viable and reliable installation practice. Certain precautions must be taken to ensure successful level measurements in these vessels. Both flexible and rigid single lead probes can be utilized for these installations.

A special mechanical configuration, Long Stud (model code option LS), can be used for the Flexible Single Lead probe to prevent contact with walls or nozzles. The Long Stud incorporates a longer rigid rod extension piece which connects to the flexible portion of the probe. This is useful for side mounted probes since it allows for the probe to extend further into the vessel before it is bent vertically down towards the tank bottom. Figure 2-9 illustrates this type of installation:

The Rosemount 3300 level transmitter can be configured with the Rosemount Configuration Tools (RCT) software by using the MA (+), MB (-) connectors. The PC communicates with the 3300 by transferring the HART protocol over the RS-485. This requires using a RS-232/RS-485 Converter.

To communicate with the 3300 transmitter, the COM port used for serial communication (RS-232) must be selected in RCT. Check the Device Manager in Windows if unsure which COM port to use.

See Help, Contents in RCT for information on how to use a specific COM port.

NOTE

Make sure the 3300 transmitter is alone on the bus and disconnect or turn off power from other devices.

Cathodic Protection The ground plane voltage is elevated in applications where the tank is

protected by a Cathodic Protection System. For HART units, an isolator should be used to protect the circuits from ground currents. A Modbus unit is more robust against ground currents, and can handle a difference of ground voltages of up to 20 V without using an Isolator.

Using an Isolator avoids undesired ground current in the 4-20 mA loop that may interfere with the correct 4-20 mA output. Installing an isolator ensures galvanic isolation between the control system and the transmitter and will break the undesired loop, preventing interference with the wanted output.

SPECIFIC APPLICATIONS

This document primarily describes two areas where our Guided Wave Radar product is an excellent choice for level or level & interface measurements. The areas are Gas Well and Oil Well applications. There are primarily three types of applications at these production sites:

• Separator tanks (horizontal or vertical)

• Production tanks

•Slop tanks

The main difference between the tanks referenced above is the process or product they contain. In gas wells, condensate (NGL) and water are the primary products, whereas crude oil and water are the primary products in oil wells.

The following description recommends which Rosemount Guided Wave Radar transmitter to use for the different applications, along with details on the proper model code for ordering. A complete list of recommended model code information is found in Appendix A.

SEPARATORS

Reference Manual

00809-0600-4811, Rev AA

February 2009

Horizontal separator (bullet tank)

Transmitter and probe selection

Horizontal separators are typically smaller in diameter and are used in both Gas and Oil fields. The recommended installation is a Rosemount 3300 with a Single lead probe.

Single Rigid Probes (model code option 4A) may be used if the tank height is less than 9 ft. 10 in. (3 m 250 mm), and for anything taller, a Single Flexible Probe (model code option 5A) must be used. If there is a high risk for a rigid probe bending during installation, a flexible probe can be used on anything taller than 3 ft. 4 in. (1 m 100 mm).

There are different materials of construction that can be used for the probes. However, Stainless Steel (316/316L) is sufficient for the majority of these applications, but material compatibility should be verified for each application.

Tank seal selection

The operating temperature is normally ambient temperature, however, the pressure will vary in different applications/separators. The product alternatives are either the Standard pressure and temperature tank seal (model code option S) or the High Pressure tank seal (model code option P).

• The standard seal is rated to 580 psig (40 bar) at maximum 302 °F (150 °C).

• The High Pressure tank seal is rated to 3500 psig (243 bar) at maximum 392 °F (200 °C) or higher pressure for a lower temperature, up to 5000 psig (345 bar) at a maximum of 100 °F (38 °C).

3-2

Model selection

The Rosemount 3302 is used for Level & Interface applications. If there is no interface and only level is required, the transmitter can be configured for Level measurement only. The separators have mounting connections either on the top or on the side of the bullet tank in a chamber. See “Process Connections” on page 2-7.

Reference Manual

• The standard seal is rated to maximum 580 psig (40 bar) at maximum 302 °F (150 °C)

• The High Pressure tank seal is rated to maximum 3524 psig (243 bar) at maximum 392 °F (200 °C) or higher pressure for a lower temperature, up to 5000 psig (345 bar) at a maximum of 100 °F (38 °C)

• One advantage of using Guided Wave Radar technology is that it can cut through foam because of its lower frequency

Rosemount Radar Level Transmitters

Vertical separator (vertical cylinder tank)

Figure 3-1. The Rosemount 3300 transmitter can be installed on vertical separator tanks.

Transmitter and probe selection

Vertical separators vary in tank height and are used in both gas and oil fields. The recommended product selection is a Rosemount 3300 with a Single lead probe. It can be installed on top of the tank. On tall vertical cylinders, the 3300 may be installed on a chamber on the lower side of the separator with the probe fully immersed.

Single Rigid Probes (model code option 4A) may be used if the tank height is less than 9 ft. 10 in. (3 m 250 mm), and for anything taller, a Single Flexible Probe (model code option 5A) must be used. If there is high risk for a rigid probe bending during installation, a flexible probe can be used on anything taller than 3 ft. 4 in. (1 m 100 mm). If the flexible probe version is used, select the probe type that has a weight attached to the end (model code option 5A).

Tank seal selection

The operating temperature is normally ambient temperature, but the pressure will vary in different applications/separators. One of the following product alternatives should be selected:

• Standard pressure and temperature tank seal (model code option S)

• High Pressure tank seal (model code option P)

Model selection

Rosemount 3302 is used for Level & Interface applications in situations where the probe is not fully immersed. The 3302 can be reconfigured for fully immersed applications in chambers. The separators have mounting connections either on top of the vertical tank or in a chamber on the lower side of the tank. These process connections are used for interface measurement. See “Process Connections” on page 2-7 for recommendations on different process connections.

Output measurement at different interface levels

Figure 3-2. Measurement levels.

Interface measurement depends on several factors. If the tank contains two products, level, interface, and thickness can be measured. However, if the upper or the lower product is pumped out, the peaks of the waveform plot must be interpreted properly to get precise measurement data.

Figure 3-2 gives an overview of the various echoes presented on a waveform plot when two products are found.

NOTE!

The measured thickness is different before and after emptying the lower product. The level measurement is done until it reaches the end of the probe.

When the lower product reaches the probe end, the signal generated turns into a constant, horizontal line, but no longer shows the actual interface. It also effects the thickness measurement.

The plot shows that there is a large layer of the upper product left after the lower product has been pumped out. In this case, both the upper product surface echo and the probe end echo are easily detected. The level and interface will not have the same value. The level will be set to the level of the upper product, and the interface (level) will be set to the probe end level.

If both the upper and lower products are pumped out, the level and interface (level) will have the same value until both the upper product surface echo and the probe end echo can be detected.

Thickness is measured from the product surface (level) to the interface. However, if the lower product is pumped out, the thickness will be measured from the product surface to the probe end only, since further signs cannot be detected.

When the tank refills, the level and interface output will be the same. Interface is not detectable until the minimum thickness requirement is reached.

PRODUCTION/SLOP TANKS

Vertical cylinder Transmitter and probe selection

Vertical cylinder tanks are holding or storage tanks where the separated product (oil or condensate) is stored before it is moved to the next step in the exploration process. These vertical cylinders vary in tank height.

If the tank is metallic, a Rosemount 3300 transmitter is sufficient. However, for a non-metallic tank, a Rosemount 5300 transmitter is required for additional EMI protection. Non-metallic tanks expose the probe to signal interference from nearby motors or cables. The 5300 provides a more stable microwave signal and improves EMI performance resulting in a more robust measurement. The recommended product selection is a Rosemount 3300 with single flexible probe with a weight attached to the bottom (model code option 5A).

Figure 3-6. The Rosemount 3300 with Single Flexible probe is suitable for metallic Vertical cylinder storage tanks.

Tank seal selection

Vertical cylinder tanks are usually vented to the atmosphere, but some have a vapor recovery system so the Rosemount 3300 standard tank seal is suitable.

For this application the Standard pressure and temperature tank seal version (model code option S) should be used. The standard seal is rated from full vacuum to maximum 580 psig (40 bar) at maximum 302 °F (150 °C).

Model selection

Most of these installations require both level and interface measurement, while some only require level measurement.

For metallic tanks, a Rosemount 3302 allows for configuring the 3300 for either Level & Interface mode or just Level.

For non-metallic tanks, a Rosemount 5302 allows for configuring the 5300 for either Level & Interface mode or just Level.

SLOP TANKS

Underground or open pit Transmitter and probe selection

Oily and dirty water, as well as residue, are pumped into slop tanks for temporary storage until further processing. Slop tanks are sometimes underground tanks, or open pits often covered with a metal cover/plate.

A Rosemount 3300 with single lead probe is recommended. Single Rigid Probes (model code option 4A) may be used if the tank height is less than 9 ft. 10 in. (3 m 250 mm). For anything taller, a Single Flexible Probe (model code option 5A) must be used. If there is a high risk for a rigid probe bending during installation, a flexible probe can be used on anything taller than 3 ft. 4 in. (1 m 100 mm).

If the flexible probe version is used, select the probe type that has a weight attached to the end (model code option 5A).

INTRODUCTION This section is a brief outline of commissioning, and does not provide

comprehensive information on the whole procedure.

To execute the commissioning process, the product-related Quick Installation Guides steps are to be followed.

COMMISSIONING The transmitter installation should be carried out as described in the Quick

Installation Guide, enclosed with every transmitter. Even though the transmitter may be installed on the bench, it must be configured according to the actual process conditions.

Do not bend the probe during any part of the installation. If it is necessary, shorten the probe, mount a centering disk, or anchor the probe during the mechanical installation. For more information see the respective Reference Manuals:

• Rosemount 5300 Series Reference Manual (Document No. 00809-0100-4530)

• Rosemount 3300 Series Reference Manual (Document No. 00809-0100-4811)

Beside these required steps, it is recommended as best practice to perform a Trim Near Zone, save a backup of the transmitter settings, and save the initial echo curve plot.

Trim Near Zone The Rosemount 3300 / 5300 Series transmitters are equipped with a firmware

functionality that minimizes the Upper Transition Zone based on the actual mounting conditions.

To activate this functionality, ensure that the tank or chamber is empty, alternatively, that the (upper) product is no closer than 40 in. (1 m), and then execute the Trim Near Zone command.

For the Rosemount 3300 Series, the Trim Near Zone command can be completed in the Radar Configuration Tools (RCT) software. Follow these steps to conduct a Trim Near Zone:

PLOTTING THE MEASUREMENT SIGNAL

Plotting the Measurement Signal for the Rosemount 3300 Series

Figure 4-2. Example of a 3300 Series Waveform plot.

The 3300 Series and 5300 Series are compatible with different softwares for plotting the measurement signal. The 3300 Series transmitter utilizes the Radar Configuration Tools (RCT) software, while the 5300 Series transmitter utilizes the Rosemount Radar Master (RRM) software.

The two software configuration programs have similar functions. Both programs have the ability to plot the measurement signal. This section explains how to view plots in RCT and RMM, and highlights the differences between the two plot views.

For the 3300 Series, the Radar Configuration Tools (RCT) program has powerful tools for advanced troubleshooting. Using the Waveform Plot function gives an instant view of the tank signal.

To plot the measurement signal:

1. Start the Radar Configuration Tools program by clicking the RCT desktop

icon: .

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

The plot shows peaks for the product surface (P2), reference pulse (P1) and end of probe (EOP). The probe end may not always be visible depending on the amount of product above.

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.

Plotting the Measurement Signal for the Rosemount 5300 Series

For the 5300 Series, Rosemount Radar Master (RRM) and other tools using enhanced EDDL have the functionality for advanced troubleshooting and plot viewing. In RRM, the waveform plot is often referred to as the Echo Curve.

To open the Echo Curve:

1. Start Rosemount Radar Master program by clicking on the RRM desktop

icon:

2. Choose the Too l s > Ec h o C u rv e menu option, or choose the Echo Curve

icon in the RRM workspace (Tools or Setup pane at the left-

hand side of the workspace) and click the Read button.

The echo curve represents the tank, as seen by the radar transmitter. Each peak corresponds to a reflection of the radar signal (e.g. the surface of the level or interface, an obstacle, or something else). By viewing single instances or movies of the echo curve, the transmitter configuration can be adjusted to achieve a reliable level measurement. Additionally, the echo curve gives insight into transmitter functionality. Usually, an echo curve analysis is not needed, because the transmitter automatically sets the appropriate parameters based on the startup information, such as tank height and tank media. However, the echo curve functionality is valuable for troubleshooting difficult applications.

Rosemount Radar Level Transmitters

Echo Curve Constituents

In a typical measurement situation, the following peaks appear in the echo curve:

Reference peak. This reference pulse is caused by the transition between transmitter head and probe.

Surface peak. This pulse is caused by a reflection from the product surface.

The measurement output from the device is presented with an arrow at the top of the plot. Normally, the output arrow points directly at the surface or interface echo peak, but sometimes the output and echo peak distance do not coincide. When this happens, a line is drawn from the echo peak to the position of the measurement output arrow.

4-7

Rosemount Radar Level Transmitters

The output arrow can be displaced when there are rapidly changing surface echo peaks because the transmitters filter the echo peaks to stabilize the measurement output. The displacement also occurs during interface measurement.

In the plot shown on page 4-7, the interface peak does not align with the interface output because the transmitter compensates for the decreased speed of microwaves through the upper product by using the dielectric constant of the upper product. The transmitters put the arrow at the actual physical distance to the interface, which is less than the distance to the interface peak.

Interface peak (5302 only). This pulse is from the reflection from the interface between the upper and lower product. This peak will only be identified by the transmitter when it is configured for Measurement Mode Level & Interface.

Various amplitude thresholds filter out unwanted signals and pick up the different peaks. The transmitter uses certain criteria to select which peaks correspond to the actual level and interface surfaces.

Counting from the top of the tank, the first echo above the Surface Threshold is considered the product surface. Pulses further from the top, although above the Surface Threshold, are ignored. When the surface echo is identified, the next pulse that is below the product surface with a signal strength above the Interface Threshold is considered the Interface.

Surface Threshold - amplitude threshold for detection of the Product level peak. The surface threshold is a number of individually adjustable amplitude threshold points, called the Amplitude Threshold Curve (ATC).

Interface Threshold - known as amplitude threshold for detection of the Interface level peak.

Upper Null Zone / Hold Off Distance - measurements are not performed within the Upper Null Zone (UNZ) / Hold Off Distance, and can be used to avoid measurements above a certain level, e.g. disturbances in the nozzle.

Differences Between Plots in RRM and RCT

Figure 4-3. Surface Threshold Curve.

There are a few differences between functionality of the Waveform Plot in RCT and the Echo Curve in RRM. In RRM, the x-axis plots the physical distance to the product or disturbance. The x-axis in RCT represents the electrical distance.

Additionally, there are a few differences in the threshold settings. RRM has automated recognition of a fully submersed probe, so there is no need for a T4 threshold. In RCT, the T2, surface threshold, setting is linear. But in RRM, the surface threshold setting is a curve that can be manipulated by moving points along the threshold curve. The T3, interface threshold, is linear for both RCT and RRM. Figure 4-3 demonstrates a multi-point threshold curve.

The following Threshold Setting scenarios are shown using the Waveform Plot tool in RCT (connected to a Rosemount 3300 Series transmitter). Threshold settings for RRM (connected to a Rosemount 5300 Series transmitter) can be similarly configured. General guidelines for 5300 threshold settings can be found on page 5-10.

The Product Dielectric Constant is wrong, resulting in an amplitude threshold T2 above the actual product surface peak.

ROSEMOUNT 5300 THRESHOLD SETTINGS

Figure 5-12. Threshold settings in Rosemount Radar Master (RRM).

The Rosemount 5300 measurement is based on the radar signal pulses reflected by the product surface and the interface between two liquids. Various signal amplitude thresholds are used to separate the measurement signal from disturbing echoes and noise. The amplitude thresholds are automatically set by the 5300 transmitter, and no manual settings are needed. However, due to the properties of the product, it may be necessary to adjust the amplitude thresholds for optimum measurement performance. The

Rosemount Radar Master (RRM) supports threshold settings in the Advanced Configuration window:

1. Click the Advanced icon in the Device Config/Setup toolbar.

2. Select the Thresholds tab in the Advanced Configuration window.

5-10

Automatic threshold settings are enabled by default. In the Advanced Configuration window the Interface, Reference, Probe End and Full Tank thresholds can be set manually.

Automatic Surface Threshold

When this check-box is selected, the transmitter automatically sets the Surface threshold to a constant value based on the configured Dielectric Constant of the product.

Note that by enabling the Automatic Surface threshold setting, the Amplitude Threshold Curve (ATC) is replaced by a constant threshold value.

The Surface threshold can also be set manually using the Set Threshold function in the Echo Curve Analyzer / Configuration Mode window.

Rosemount Radar Level Transmitters

Probe End Threshold

If the Probe End Projection function is used, this threshold may need to be adjusted so the probe end pulse is properly detected.

Full Tank Threshold Offset

The Full Tank threshold is related to the Reference Threshold, and can detect that the tank is full. The given offset value determines the gap between the Reference threshold and the Full Tank threshold. The transmitter considers the tank full when the amplitude of the Reference Peak has dropped to a value between the two threshold values.

If the amplitude of the Reference peak is below the Full Tank Threshold (negative amplitude of the Reference peak) the tank is not considered full.

The Full Tank Threshold Offset should be set so the Full Tank Threshold coincides with an amplitude value equal to 90% of the Reference Echo peak amplitude when the tank is not full.

Example

In the example below the following assumptions are made (note the negative sign):

Figure 5-13. Example of how to specify the Full Tank Threshold.

Reference Echo peak amplitude = -2000 mV.

Reference Threshold = -1000 mV.

The target position for the Full Tank Threshold is 10% below the Reference Echo peak amplitude. In this example the Full Tank Threshold should be located at 10% below the Reference peak at -2000 mV:

-2000 mV - (-200 mV)= -1800 mV.

Since the Full Tank Threshold refers to the Reference Threshold, the resulting offset value has to be expressed in terms of the distance to the Reference Threshold:

Full Tank Threshold Offset = -1000 mV - (-1800 mV) = +800 mV.

INTRODUCTION Once a Rosemount 3300 / 5300 transmitter is installed and configured, it will

continuously deliver measurement data with a minimum of maintenance. Transmitter performance should be verified on a regular basis to ensure proper function.

• Configure and commission the transmitter as described in this document and the Rosemount 3300 / 5300 Series Reference Manuals (Document No. 00809-0100-4811 and 00809-0100-4530)

• If needed, adjust threshold settings, Upper Null Zone settings, Trim Near Zone, or mechanical nozzle adjustments

• When using the 3300 Series, run the Self Test function to verify there are no transmitter hardware or software errors. The 5300 Series automatically performs a self test

• View and save a waveform plot for the configured transmitter. A plot function is available in the Radar Configuration Tools (RCT) for the 3300 Series, and in the Rosemount Radar Master (RRM) software for the 5300 Series. The plot is used as a baseline for future reference when verifying the transmitter

• For the 5300 Series, additional diagnostics capabilities eliminate the need for verification self-tests. The following information can be retrieved about the device:

- device status

test:

1. Open the Tools section in the RCT workspace Project Bar.

2. Click the Device Commands icon, or choose the Device Commands

option from the View menu.

3. Open the Diag folder and double-click the Self Test option.

4. Verify that the Self Test result is successful.

Rosemount 3300 Plot Verification

Figure 6-2. Rosemount 3300: Mesurement conditions can be analyzed by using the Waveform Plot.

To verify the Rosemount 3300 level measurement, read a waveform plot and save it on a disk. Open the original plot from the original transmitter commissioning and compare it to the new plot. Use the check list below to verify sufficient signal/noise ratio and proper amplitude threshold values.

1. Check the Reference pulse amplitude and position.

Ensure that the margin to T1 is sufficient. If the Reference pulse amplitude peak is above the threshold T1, the transmitter will report “Full Ta nk ” .

2. Check the noise amplitude versus threshold T2.

The noise level may increase when the probe is coated, reducing the margin to surface threshold T2. An insufficient margin may lead to the wrong peak being interpreted as the product surface.

3. Check the margin between signal peak P2 and surface threshold T2.

Robust measurement is achieved from having a margin that allows minor amplitude fluctuations because of a turbulent product surface or coated probe. Failure to detect the product surface, or the wrong peak being interpreted as the product surface may be from a margin that does not allow minor amplitude fluctuations.

4. Check the signal/noise ratio, i.e. the maximum noise amplitude/peak amplitude P2.

An incorrect ratio may cause failure to detect the product surface, or the wrong peak being interpreted as the product surface.

5. Check the margin between interface peak P3 and amplitude threshold T3.

If the margin is incorrect, it may lead to failure.

Rosemount 5300 Plot Verification

Recommendations for the Rosemount 5300 Series:

1. Use of the automatic threshold settings ensures that the dielectric constants of the upper and lower products have been entered correctly.

2. If needed, apply the Measure and Learn function.

3. Use the following best practices to apply custom threshold adjustments, if necessary:

• Generally, the threshold should be at 40-50% of the surface peak. Example: If the surface is 2000 mV, the threshold should be set at 800-1000 mV

• The threshold should never be closer than 300 mV to a disturbing object. Example: If there is a 1100 mV peak from an inlet pipe, the threshold around it should be 1400 mV

The threshold should never be below 800 mV in the range 0-1 ft. (0.3 m) and never below 500 mV from ranges above 1 ft. (0.3 m).

For products with very low dielectric constants, such as solids, it may be necessary to lower the threshold.
