2.3.1Trim Near Zone
Note
Trim Near Zone should not be performed on Dynamic Vapor Compensation or Coaxial probes.
Use Trim Near Zone when mounted in a nozzle, chamber, or still-pipe. An exception is narrow
nozzles as defined below:
2 in. (50 mm) < Nozzle height < 12 in. (300 mm)
Nozzle diameter < 2 in. (50 mm) for all single probes
(Nozzle diameter < 3 in. (75 mm) for 13 mm single rigid)
™
To co m plete the Trim Near Zone f u n ction:
1.Make sure the product level is below the near zone region (3.3 ft [1 m] from the flange
face).
2.Select Trim Near Zone and follow the instructions.
Note
Trim Near Zone should not be completed when the unit is installed in an empty metal tank. A
small amount of fluid should be added before the Trim Near Zone step is completed.

Section 2: Installation & configuration
March 2015
2.3.2Other optional advanced configurations
Other functions that may be required can be found in Appendix C of the reference manual.
Some of these may only be needed in certain conditions. This includes settings for:
Hold Off Distance/Upper Null Zone which defines how close to the upper reference
point a level value is accepted. This will block out false targets and measurements in this
area.
Threshold settings which determine the minimum signal amplitude limits of key
parameters such as the surface echo, interface echo, reference peak and end of probe
peak.
Probe End Projection is used to support the surface measurement in low dielectric
materials and when the surface is close to the end of the probe.
Echo tracking may be needed to enhance the measurement tracking capabilities in
some conditions such as rapid level changes or excessive turbulence
Dielectric constant settings may need adjustment in interface or saturated steam
applications.
Dynamic Vapor Compensation is used in saturated steam applications with a probe that
includes a steam compensation reflector.
Signal Quality Metrics are used to indicate the integrity of the surface signal compared
to the noise. It could be used to detect excessive coating on the probe or the presence
of some heavy foams.

2.4.3Review echo curve
1.Download and review the echo curve
2.Verify that the reference pulse is detected
3.Review peak amplitudes
For an empty vessel, verify the probe end pulse is visible. If the probe is grounded
(the end of the probe is touching a metal surface) or SST centering disk is used,
the pulse is positive. Otherwise the pulse will be negative.
Verify that no disturbing echoes are present above the Surface Threshold (ATC).
Note
Figure 2-8 illustrates the key elements of a theoretical echo curve. In an actual echo curve, the
probe end pulse and the probe end echo threshold line are not visible in an interface application,
they are shown for illustration purposes only.

2.5Common problems and recommended actions
2.5.1Double bounce
Tall, narrow, and/or rough nozzles may create double bounces, which disturb the measurement
signal. The double bounce always appears at twice the disturbance distance. For example, the
end of the nozzle may create a peak at 10 in. (254 mm). A second peak will appear at 20 in.
(500 mm).
Note
Trim Near Zone should not be completed when the unit is installed in an empty metal tank. A
small amount of fluid should be added before the Trim Near Zone step is completed.
Recommended actions:
Verify that mounting considerations are followed, as described in Section 3.2 Mounting
Considerations in the Rosemount 5300 Series Reference Manual (document number
00809-0100-4530).
Perform Trim Near Zone. See Appendix C.3.1 Use the Trim Near Zone Function in the
Rosemount 5300 Series Reference Manual (document number 00809-0100-4530) for
activation details. Fine-tune performance by trimming echoes in the near zone.
Adjust Upper Null Zone (UNZ). See Appendix C.3.2 Changing the Hold Off
Distance/Upper Null Zone in the Rosemount 5300 Series Reference Manual (document
number 00809-0100-4530) for details. Exclude any echo “before” the UNZ.
Installation and Configuration
Adjust Surface Threshold (ATC). See Appendix C.4 Threshold Settings in the Rosemount
5300 Series Reference Manual (document number 00809-0100-4530) for details.
Exclude any echo weaker than the threshold.

2.5.2Strong fixed echo - bent probe/probe contacting nozzle
A probe in contact with metal creates a strong echo and the measurement will lock onto the
strong echo.
Note
Heavy contamination may also create strong disturbance echoes.
Figure 2-9. Echo Curve with a Bent Probe
Recommended actions:
If bent probe, try to straighten it gently. If this is not possible, a replacement of the
complete probe assembly may be required.
Verify that mounting considerations described in Section 3.2.5 Mounting in
Chamber/Still Pipe in the Rosemount 5300 Series Reference Manual (document
number 00809-0100-4530) are fulfilled. The probe length should be slightly shorter
than the chamber length.
Consider adding a centering disc at the bottom of the probe. For more information, see
Section 3.3.9 Mounting a Centering Disc for Pipe Installations in the Rosemount 5300
Series Reference Manual (document number 00809-0100-4530). This helps to keep the
probe centered in the chamber/still-pipe.
If flexible probe in contact with nozzle, consider using a long stud. For more
information, see Section 3.2 Mounting Considerations in the Rosemount 5300 Series
Reference Manual (document number 00809-0100-4530).

b.General noise floor amplitude (see Figure 3-2)
The noise floor should be relatively flat with low amplitude. This can vary with the
size and shape of the chamber internal structure. For example, some inlet
connections may have a rough weld edge and this can result in a small
disturbance on the echo noise floor. In general, the noise floor should be
relatively flat and below the general threshold setting.

Section 3: Verification and Validation of GWR without Fluid
March 2015
c.End of probe peak (see Figure 3-3)
The end of probe peak is affected by the probe type and the use of centering
discs. A metal centering disk will give a positive peak slightly offset from the
probe end. No centering disc or a non-metallic centering disc will result in a
negative probe end peak.
Figure 3-3. End of Probe Peaks
Reference Manual
00809-1600-4530, Rev AA

The use of weights will results in a positive peak at the top of the weight and a
negative peak at the bottom. The distance between the positive and negative
peak varies with the length of the weight.
4.(Optional) If using a verification reflector, note location of reflector pulse
(see Figure 3-4) please see “Verification reflector” on page 32 for more detail. Perform

4.1Verification procedure with active level
measurement
March 2015
At normal operating conditions, compare the transmitter level, or interface reading, with an
independent measurement. Unfortunately, it often happens that two independent
measurements do not match up perfectly, but check the sanity and the acceptable deviation.
Verify the correctness of level reading
The independent measurement can be done using a number of different complementary
devices, ranging from sight-glasses and hand-dipping to redundant differential pressure and
displacer transmitters.

Echo curve verification at operating conditions
At normal operating conditions, download and review the echo curve according to the following
steps:
1.Check reference pulse amplitude and position. Compare the result against the previous
plots, taken during cold startup.
2.Review peak amplitudes and threshold settings. Verify that the surface and/or interface
peaks are visible and that the thresholds have been set as described in threshold
settings. See Tab l e 4- 1below for rough guidelines of amplitudes. For information on
threshold settings, see “Common problems and recommended actions” on page 25.

4.7.1Other validation suggestions
To validate a device, do one of the following:
Check the end of probe peak and label when the vessel or chamber is completely
empty. Check if the peak corresponds to the EOP label. If it does not correspond, check
the probe length that was used in the configuration.
Check if there is an alternative measurement. Compare it to the GWR result. An
Magnetic Level Indicator (MLI) can be used, but with the caveat that the MLI is
density-dependent. For example, if the MLI float is sized to be used with oil, but the
validation is completed with water, the MLI and the GWR will be offset. The GWR will
track the surface regardless of the fluid density.
If the verification reflector is present, check its location to validate a reading after the
reflector calibration is complete.
Check if SQM is used. On a clean probe and a high dielectric fluid, the signal quality
value should be high (>8).
For an interface measurement, use an alternative way to know the interface, for
example a sight-glass. The DC of the upper fluid may need to be adjusted to make the
interface given by the GWR match the interface from the sight glass. The dielectric
calculator tool in RRM can be used to assist with this adjustment.
Additional options are available for the Rosemount 5300 that can be useful for diagnostics
under operating conditions.
5.2Signal Quality Metrics (SQM)
Section 5: Additional Options
March 2015
SQM indicates the surface signal integrity compared to the noise. It can be used to schedule
maintenance to clean the probe or detect and monitor turbulence, boiling, foam, and
emulsions.
The following diagnostics measurements are available:
Signal quality is a measurement of the surface peak amplitude compared to the surface
threshold (ATC) and the smallest marginal between the noise and the ATC above the surface
(indicated with a circle) compared to the ATC. The signal quality spans from 0 to 10, where 0
indicates a low margin, and 10 indicates a high margin. It indicates how much margin there is
until the noise peak is indicated as the surface level. Surface/noise margin is the relationship
between surface peak amplitude and the amplitude of the strongest noise peak above the
surface. The surface/noise margin spans from 0 to 10, where 0 indicates a low margin, and 10
indicates a high margin. It indicates how much disturbance the device can handle in the tank.
Note
Since signal quality is reflective of the surface conditions, the probe, and the threshold settings,
it intended to be used while the device is measuring level. It is not considered a valid parameter
when the tank or chamber is empty.
Note
The signal amplitude and the noise margin depend on probe type and application conditions, as
well as the condition of the probe. Even if the probe is clean, signal quality and surface/noise
margin may not be a 10.
Additional Options
To check if the SQM function is supported, do one of the following:
If “DA1” or “D01” is mentioned in the model code on the label, the device supports
Signal Quality Metrics. Model Code: 530xxxxxxxxxxxxxxxxDA1 or
530xxxxxxxxxxxxxxxxD01xx

In a Field Communicator, if SQM is supported, it can be found with the [3, 2, 2, 1]
sequence. Check if “Diagnostics Suite” is present.
SQM can be enabled/disabled in Rosemount Radar Master. Select Setup > Advanced and select
the Signal Quality Metrics tab.
Note
If SQM is not supported or disabled, the signal quality and surface/noise margin will always be
set to 0.

device supports Signal Quality Metrics.
5.3Verification reflector
The reflector, which is available with single lead flexible probes, is used to test and continuously
verify that the transmitter functions properly in both tank and chamber/pipe installations.
Compared to traditional diagnostics that only monitor the transmitter electronics, the reflector
can also be used to diagnose the upper parts of the probe inside the tank for example build-up,
corrosion monitoring, and other process related conditions.
The primary use-cases for the reflector are:
Verification of transmitter and probe (proof-testing)
High level supervision (continuous monitoring of high level condition)
Figure 5-1. Verification Reflector
32
Additional Options
Reference Manual
00809-1600-4530, Rev AA
5.3.1High level supervision
Additionally, the reflector’s unique echo characteristics aid the transmitter to locate a liquid
surface above the reflector, thereby offering increased reliability to detect high level conditions
at a user selectable limit. The transmitter continuously monitors the status of the reflector and
abnormal conditions generate alarms and alerts as appropriate.
5.3.2Limitations for verification reflector
Not to be used in fully submerged applications
Minimum dielectric constant:
2.4 (for option code HL1)
2.0 (for option code HL2 and HL3)
Verification reflector must be installed at least 20 in. (0.5 m) below the flange face. In addition,
during the calibration procedure, the level surface must be as least 20 in. (0.5 m) below the
reflector.
More information
Section 5: Additional Options
March 2015
For more information and installation requirements, refer to the High Level Supervision Manual
(document number 00809-0900-4530).
The device should be installed and configured as a level sensing device per manufacturer’s
instructions. The materials must be compatible with process conditions and process fluids. No
special installation is required in addition to the standard installation practices outlined in this
manual.
The loop must be designed so that the terminal voltage does not drop below the minimum
input voltage when the transmitter output is 22.5 mA. See values in Tab le 6 - 1.
Section 6: SIS Installations
March 2015
It is assumed that the personnel installing, configuring, and operating the system have the
knowledge equal or greater than that of a qualified instrument technician familiar with
safety-related systems, process control applications, and general instrument use.

6.2Configuring in SIS applications
Use a HART® compliant master, such as Rosemount Radar Master (RRM) or a Field
Communicator, to communicate with and verify configuration of the Rosemount 5300 Series.
These instructions are applicable to the Rosemount 5300 Series safety-certified options with
any differences noted.
Damping
User-adjusted damping will affect the transmitter’s ability to respond to process changes.
Therefore, the damping values + response time should not exceed the loop requirements.
Alarm and saturation levels
DCS or safety logic solver should be configured to handle both High alarm and Low alarm. It is
also required that the transmitter is configured for High or Low alarm. Figure 6-1 identifies the
alarm levels available and their operation values
Figure 6-1. Alarm Levels and Operation Values
(1)
.
Reference Manual
00809-1600-4530, Rev AA
It is assumed that the current output signal is fed to a SIL 2-compliant analog input board of a
safety logic solver.
Note
Only the High or Low Alarm Mode can be used for the safety function. Do not choose Freeze
Current.
Write protection
A Rosemount 5300 Series safety-certified transmitter should always be protected from
unintentional configuration changes by a password protected function.
(1) In certain cases, the transmitter does not go into the user defined alarm state. For example, in case of a short circuit, the transmitter goes into High Alarm state even
if Low Alarm has been configured.

Reference Manual
00809-1600-4530, Rev AA
Site acceptance
After installation and/or configuration, proper operation of the transmitter (including
verification of all configuration changes) must be verified. A site acceptance test is therefore
required. The proof test outlined in this document can be used for this.
6.3SIS operation and maintenance
6.3.1Proof test
The following proof test is recommended. If an error is found in the safety function, the
measuring system must be switched out of service and the process held in a safe state by means
of other measures. Proof test results and corrective actions taken must be documented at
http://www.rosemount.com/safety.
Note
For a valid result, always perform the proof test on the product that will be stored in the tank
while the device is in operation.
Section 6: SIS Installations
March 2015
Note
Before every test, make sure you are connected to the correct transmitter by verifying QT/QS in
the model code on the label and your software version. Also verify that the serial number on the
label matches the one in your configuration tool. Make sure to enable write protection as soon
as you are finished.
Required tools: HART host/communicator and mA meter.
Note that prior to these tests, inspect the echo curve to ensure that no disturbing echoes
affecting the measurement performance are present.
