The transmitter continuously emits signal sweeps with a constantly varying frequency towards the product surface. Since the transmitter continuously changes the frequency of the transmitted signal, there will be a difference in frequency between the transmitted and the reflected signals (see Figure 2-1). The frequency of the reflected signal is subtracted from the frequency of the signal transmitted at that moment, resulting in a low frequency signal which is proportional to the distance to the product surface. This signal is further processed to obtain fast, reliable, and highly accurate level measurements. Figure 2-1: FMCW-method fd=distance A. Frequency (GHz) B. Time (s) C. Transmitted signal D. Reflected signal 2.2 Process characteristics 2.2.1 Dielectric constant A key parameter for measurement performance is reflectivity. A high dielectric constant of the media provides better reflection and enables a longer measuring range. Rosemount 3408 Level Transmitter 9 dfinfmaxfminfoutfinfouttfACDB Transmitter overview September 2022 Reference Manual 00809-0100-4418 2.2.2 Foam and turbulence Foaming liquids or turbulence may cause weak and varying surface echo amplitudes. Surface turbulence is not normally a problem unless it is excessive. Measurement in foamy applications depends largely on the foam properties. When the foam is light and airy, the actual product level is measured. For heavy and dense foam, the transmitter may measure the level of the foams upper surface. The Double Surface Handling function allows the user to select if the foam layer or product surface should be used as output. Related information Process conditions Double surface handling 2.3 Vessel characteristics 2.3.1 In-tank obstructions The transmitter should be mounted so that objects such as heating coils, ladders, and agitators are not in the radar signal path. These objects may cause false echoes resulting in reduced measurement performance. However, the transmitter has built-in functions designed to reduce the influence from disturbing objects where such objects cannot be totally avoided. Vertical and inclined structures cause minimal effect since the radar signal is scattered rather than directed back to the antenna. 2.3.2 Tank shape The shape of the tank bottom affects the measurement signal when the product surface is close to the tank bottom. The transmitter has built-in functions which optimize measurement performance for various bottom shapes. 2.4 Non-contacting radar technology Non-contacting radar technology is ideal for a wide range of applications as it is maintenance-free, has a top-down installation that reduces the risk of leakages, and is unaffected by process conditions such as density, viscosity, temperature, pressure, and pH. The Rosemount 3408 uses Frequency Modulated Continuous Wave (FMCW) technology and smart algorithms to maximize measurement accuracy and reliability, even in small tanks and challenging fast-filling vessels. 10 Emerson.com/Rosemount Reference Manual 00809-0100-4418 Transmitter overview September 2022 2.4.1 Application examples Storage tanks Ensure correct filling and storage levels in your tanks. Mixing tanks Gain insights into your process and ensure production runs smoothly without interruption.

The output is a 4-20 mA analog signal superimposed with a digital HART signal. By using the optional Rosemount 333 HART Tri-Loop, the digital HART signal can be converted into three additional 4-20 mA analog signals. With the HART protocol, multidrop configuration is possible. In this case, communication is restricted to digital, since current is fixed to the 4 mA minimum value. The transmitter can be combined with the Emerson Wireless 775 THUM Adapter to wirelessly communicate HART data with IEC 62591 (WirelessHART) technology. In addition, the transmitter can be connected to a Rosemount 751 Field Signal Indicator, or it can be equipped with an integral display (available with optional Bluetooth wireless technology).

Rosemount 3408 Level Transmitter 93 Service and troubleshooting September 2022 Reference Manual 00809-0100-4418 7.5 Application challenges 7.5.1 Managing disturbance echoes There are two general methods for managing disturbance echoes:

Set amplitude threshold to filter out weak disturbance echoes and noise. Use the suppress false echoes function to manage strong disturbance echoes. Amplitude threshold The amplitude threshold is used to filter out noise and disturbing echoes from the product surface echo. The transmitter uses certain criteria to decide which type of echo peak that is detected. Only echoes above the amplitude threshold might be considered the product surface. The amplitude threshold can either be set to a constant value, or split into sections as defined by up to 10 anchor points. If necessary, a customized amplitude threshold section can for instance be used to remove the influence from the tank nozzle, or disturbances close to the tank bottom. Additionally, it might be needed in areas where there are occasionally strong echoes present, for instance due to wide mixer blades. Suppressing false echoes may not be sufficient in those areas. Note Do not create a customized amplitude threshold section around echoes which are already registered as false echoes. Adjust the amplitude threshold If necessary, the amplitude threshold can be increased if a disturbance echo is interpreted as the product surface. Alternatively, a lower threshold may be required to handle weak surface echoes (e.g. due to excessive foaming or turbulence). Prerequisites The amplitude threshold is set at factory for optimum performance and should not normally need an adjustment. Before changing the factory default, study the position and amplitude of the different echo peaks. It is recommended to adjust thresholds using Rosemount Radar Master Plus. Procedure 1. Select Service Tools Echo Curve. 94 Emerson.com/Rosemount Reference Manual 00809-0100-4418 Service and troubleshooting September 2022 2.

Rosemount 3408 Level Transmitter 95 Service and troubleshooting September 2022 Reference Manual 00809-0100-4418 2. Click again on one of the amplitude threshold points and select Save. Suppressing false echoes Stationary objects with horizontal surfaces may generate strong false echoes. When the surface is close to an obstruction in the tank (e.g. beams and agitators), the surface and false echoes might interfere and cause a decrease in performance. However, false echoes can be suppressed to reduce the influence of such objects, in case they cannot be totally avoided. When the surface is passing by a disturbing object, the transmitter will then measure with higher reliability, even if the surface echo is weaker than the false echo, see Figure 7-20. Figure 7-20: Suppression of False Echoes A. Amplitude threshold B. Disturbing object C. False echo suppression D. Suppressed echo E. Surface Add a new false echo suppression Prerequisites Follow these recommendations before suppressing new false echoes:

Make sure a correct amplitude threshold is set. Make sure the level is stable. A fluctuating level may indicate a temporary disturbance which is not due to an interfering object. 96 Emerson.com/Rosemount meter001 0002 0003 0004 0005 0006 0007 000mV0.51.01.52.02.53.03.5DBAEC Reference Manual 00809-0100-4418 Service and troubleshooting September 2022 Only suppress echoes which can be clearly identified as objects in the tank. Compare the list of interfering echoes with the tank drawing or visual inspection of the tank. Do not suppress false echoes located below the product surface.

This zone can be extended to block out disturbing echoes at the top of the tank. Prerequisites Note Make sure the Upper Range Value (100%/20 mA) value is below the Upper Null Zone. Measurements are not performed within the Upper Null Zone. Procedure 1. Identify desired Upper Null Zone using the echo curve plot. a) In Rosemount Radar Master Plus, start the echo curve reading. b) View the echo curve plot to find out if there are disturbing echoes close to the transmitter. 2. Set the desired Upper Null Zone value. a) Select Configure Level Setup Antenna. b) Under Advanced, type desired Upper Null Zone, and then select Save. Related information Read the echo curve Upper null zone 7.5.3 Tracking of weak surface echoes close to tank bottom Use tank bottom projection The Tank Bottom Projection function can be used to enhance measurement performance in the tank bottom region. If the product surface echo is weak in the tank bottom region and the bottom echo is strong (typical for flat tank bottoms), the transmitter may lock on the bottom echo and report a false level measurement (empty tank). If the application requires, the Tank Bottom Projection settings can be user-defined. Figure 7-23 illustrates an example of the Tank Bottom Projection when the tank is being emptied.

Select Save. 7.5.4 Handling strong double bounce echoes Double bounces are most commonly present in spherical or horizontal cylinder tanks, and usually appear when the tank is about 60-70 percent filled. In these cases, the amplitude may be strong enough for the transmitter to interpret the double bounce as the surface echo. The Double Bounce Handling function is used for managing such problems. A double bounce echo occurs when a radar signal bounces back and forth between the product surface and tank roof (or other object within the tank) before it is detected by the transmitter. Normally, these signals have a low amplitude and are ignored by the transmitter. Figure 7-25: Double Bounce Echoes A. Distance to surface B. Distance to first double bounce C. Actual level D. Virtual level (first double bounce) E. Signal amplitude F. Distance Prerequisites Note The Double Bounce Handling function should only be used if the problem of double bounces cannot be solved by changing the mounting position. 102 Emerson.com/Rosemount ABCEFD Reference Manual 00809-0100-4418 Service and troubleshooting September 2022 Note The surface echo is required to suppress the double bounce. If the surface echo enters the Upper Null Zone, there is no product surface reference and the double bounce might be interpreted as the surface echo. The Double Bounce Handling function is only available in Rosemount Radar Master Plus. Procedure 1. Read the echo curve plot to determine if double bounce echoes are present. 2. Select Configure Level Setup Advanced. 3. Under More Advanced Options, select Echo Tracking. 4. 5. In the Double Bounce Handling list, select Enabled or Disabled. If you enabled Double Bounce Handling, then enter desired Double Bounce Offset. 6. Select Save.

The transmitter operates in either standard mode with a 4 20 mA output signal or in multidrop. When the transmitter is in multi-drop mode, the current output is fixed to 4 mA. Burst mode When set to burst mode, the transmitter regularly sends out messages instead of waiting for the host to request it. Both the transmitter and host must be configured to operate in burst mode. Almost all HART host systems today are designed to communicate in poll/response mode, not burst mode. However, the Rosemount 333 HART Tri-Loop requires burst mode communication. Related information Use with the Rosemount 333 HART Tri-Loop Variable mapping Up to four device variables can be assigned for the HART protocol. The transmitter outputs a 4-20 mA signal proportional to the primary variable. Additional variables are available through the HART digital signal. Related information Output variables Damping value This parameter defines how fast the transmitter reacts to a change of the level value (step response). The default value is 2 seconds. A high value makes the level reading steady, while a low value allows the transmitter to respond to rapid level changes (but the presented level value may be less steady). Percent of range auxiliary Set this parameter to output the percent of range for another device variable (in addition to the primary variable).

Show negative level as zero When this setting is selected and the product surface is at or below Zero Level, the level measurement output will be zero. B.3.2 Environment Process conditions Foam This parameter should be used if there is, or may be, surface foam. When setting this parameter, the transmitter is optimized for conditions with weak and varying surface echo amplitudes, which is typical for presence of surface foam. Turbulent surface Set this parameter to improve the performance of the transmitter when there are small and local rapid level changes caused by surface turbulence. The reason for the turbulence might be splash loading, agitators, mixers, or boiling product. Cleaning in place Optimize measurement performance for applications with tank cleaning processes. Maximum level rate Fastest rate that may occur in the monitored process to (partially) fill or empty this tank. Note that product level rate may be higher during upset conditions. Product dielectric range Select the range of the dielectric constant for the product in the tank. If the range is not known, or if the product in the tank is changed on a regular basis, then select Default. B.3.3 Volume Select if the volume measurement should be calculated from the configured tank dimensions or a strapping table. Strapping tables can be used for irregularly shaped tanks, to eliminate errors due to bulging when product is added to a tank, or if a pre-defined tank type does not provide sufficient accuracy. 130 Emerson.com/Rosemount Reference Manual 00809-0100-4418 Configuration parameters September 2022 Strapping table Strapping table requires entering level-volume pairs in a table (maximum 50 points). Use most of the strapping points in regions where the tank shape is non-linear. Starting at the bottom of the tank, for each new point, enter the total volume up to the specified level value. Volume offset Use this parameter to add a volume to each calculated volume value, for example a sump volume below the Zero Level in the tank. B.3.4 Scaled variable The scaled variable can be used to convert a device variable into an alternative measurement, such as open channel flow, mass, or calibrated level (e.g. 5 point verification). This variable is available only for transmitters ordered with Smart Diagnostics Suite. The scaled variable is defined by creating a table of device variables and corresponding output variables. A maximum of 50 points can be specified. Between the points linearly interpolated values are calculated. Figure B-12: Scaled Variable Examples Input Variable:

B.3.5 Antenna Antenna type The transmitter is designed to optimize measurement performance for each available antenna type. This parameter is pre-configured at factory; it only needs to be set if the antenna is changed to another type, or if you have installed a spare transmitter. User defined antenna options These antenna parameters are applicable to customized antennas only. The settings are typically provided by factory. Upper null zone The Upper Null Zone defines how close to the device's reference point a level value is accepted. You can extend this value to block out disturbing echoes close to the antenna, for example from the tank nozzle. Note Make sure the 20 mA value is below the Upper Null Zone. Measurements are not performed within the Upper Null Zone (UNZ). Figure B-13: Upper Null Zone A. Upper Null Zone B. Disturbance echo C. Amplitude threshold D.

Product dielectric constant estimation is frozen if any of these conditions are not fulfilled. Unit Units of measurement of the user defined variable. More advanced options More advanced options are only available in Rosemount Radar Master Plus. By default, these parameters are automatically set based on current configuration. It is recommended that these parameters should remain at the default settings, unless there is a good understanding of the function and capability of the parameters. Empty tank handling The Empty Tank Handling functions handle situations when the surface echo is close to the tank bottom. 134 Emerson.com/Rosemount Reference Manual 00809-0100-4418 Configuration parameters September 2022 Table B-4: Empty Tank Handling Parameter Description Empty tank detection area Bottom echo visible when tank is empty The Empty Tank Detection Area defines a range where it is accepted to lose the echo from the product. If the echo is lost in this range, the tank is considered empty and the level is presented as 0. When the tank is empty, the transmitter looks in this range for the product surface. When a new echo is found in this range, it is considered to be the product surface. Therefore, if there are disturbance echoes in this area, they may need to be filtered out. This function requires the Bottom echo visible when tank is empty parameter to be disabled. Only enable this parameter if the bottom echo is visible when tank is empty. By setting this parameter, the bottom echo will be treated as a disturbance echo to facilitate tracking of weak surface echoes close to the tank bottom. Related information Enable bottom echo visible when tank is empty Tank bottom projection The Tank Bottom Projection is used to enhance measurement performance near the bottom of the tank. When the tank bottom echo is strong (typical for flat tank bottoms) and the dielectric constant of the product is low (e.g. oil), the transmitter may lock on the bottom echo and report a false level measurement (empty tank). This problem can be solved by using the Tank Bottom Projection function. Table B-5: Tank Bottom Projection Parameter Description Bottom product dielectric constant Maximum projection distance Minimum tank bottom amplitude Related information Use tank bottom projection Enter the product dielectric constant for the product in the bottom of the tank. This defines the range where the function is active. Enter the maximum distance from the zero level (tank bottom). Enter the minimum allowed amplitude for the echo from the tank bottom before this function is activated. Rosemount 3408 Level Transmitter 135 Configuration parameters September 2022 Reference Manual 00809-0100-4418 Echo tracking Surface echo tracking Use these settings to configure how the transmitter should keep track of the surface. These are advanced settings. Normally, they should not be changed. Table B-6: Surface Echo Tracking Parameter Search window size Track first echo Description This parameter defines a window centered at the current surface position where new surface echo candidates can be selected. The size of the window is Search Window Size. Echoes outside this window will not be considered as surface echoes. If there are rapid level changes in the tank, the value of the Search Window Size can be increased to prevent the transmitter from missing level changes. On the other hand, a large value may cause the transmitter to select an invalid echo as the surface echo. Select the Track First Echo check box if the first echo above the amplitude threshold always should be considered as the surface echo. Note Before enabling Track First Echo, analyze the echo curve and check amplitude thresholds. Double surface handling If there are multiple products in the tank, the Double Surface Handling function can be manually set to allow user to select if the upper or lower product should be used as output. The upper and lower surface echoes must be stronger than any disturbance echoes in the search region for Double Surface Handling to function properly. Table B-7: Double Surface Handling Parameter Track upper surface Track lower surface Upper product dielectric constant Description Track upper surface when there are multiple products in the tank (for example thin oil layer on top of water). Track the lower product surface, such as the interface when there are multiple products in the tank, or the product surface instead of a foam layer. Enter the dielectric constant for the upper product. A more precise value results in better accuracy for the lower surface level. 136 Emerson.com/Rosemount Reference Manual 00809-0100-4418 Configuration parameters September 2022 Double bounce handling Use this function to prevent transmitter from locking on strong double bounce echoes

(may occur in spherical and horizontal cylinder tanks). Related information Handling strong double bounce echoes Overfill prevention The Overfill Prevention function adds an extra layer of protection to prevent tank overfills. The function uses an independent echo logic algorithm to identify the surface echo close to the top of the tank. In the unlikely event there is a conflict between the normal and the overfill prevention echo logic, the Overfill Prevention function will have a precedence in determining the position of the surface. The transmitter will then output this new value, or generate an alarm if the normal echo logic is not able to find the surface echo at the new position. The Overfill Prevention Range defines the lower end of the range in which the function operates. The range is configurable. Expert options Use the expert options to view input registers, and to view and edit holding registers. Note Instructions for how to use Expert options are typically provided by factory and should only be modified if required. Related information View input registers View holding registers B.4 Alert setup B.4.1 Measurement recovery Measurement recovery time The Measurement Recovery Time (Echo Timeout) parameter controls the maximum time from when measurement is lost (e.g. due to process conditions such as foam or turbulence) until it is annunciated. If measurement is recovered within the time specified by this parameter, then it will not be annunciated. Measurement recovery handling By default, the Measurement Recovery Time is set up automatically by the device based on the transmitter configuration. It is recommended to leave the Measurement Recovery Handling at default unless required by your application. A higher value may be entered to increase robustness and Rosemount 3408 Level Transmitter 137 Configuration parameters September 2022 Reference Manual 00809-0100-4418 avoid nuisance alarms. Only enter a lower value if lost measurement is required to be annunciated within a certain time for your application. Used measurement recovery time This is the value used by the transmitter. B.4.2 Signal quality alert This section applies only to transmitters ordered with Smart Diagnostics Suite. Signal Quality is a measure of the product surface echo amplitude compared to the surface threshold and noise. The Signal Quality spans from 0 to 10. A low value means that there is a risk for the noise peak to be mistaken for the product surface peak. Note The Signal Quality may not be 10 even if the antenna is clean. The value depends on antenna type, application conditions, configured surface threshold, as well as the condition of the antenna. Build up on the antenna and different surface conditions are factors that can result in a low Signal Quality value. By setting an alert, the Signal Quality value can be used to schedule maintenance to clean the antenna, fine-tune the surface threshold, or detect and monitor adverse surface conditions such as turbulence or foam. Suitable alert limits vary from application to application. Appropriate value can be determined by logging Signal Quality over time and viewing maximum/minimum values. The Signal Quality Alert limit should be at least 1, but a better guideline is 2-3. Figure B-15: Signal Quality Alert A. Signal quality B. Time C. Alert ON D. Deadband E. Limit F. The Signal Quality drops below the alert limit and an alert message is triggered. G. The alert message is reset once the Signal Quality value rises above the Deadband range.
