2.1 DP Level and remote seal system measurement
DP Level is a reliable measurement solution for measuring level, density, interface, or mass of a process
media inside a tank.
Remote seal system measurement is unaffected by agitation, foam, or internal obstacles. Remote
diaphragm seals extend limitations due to process conditions such as high and low temperatures,
corrosive processes, viscous mediums, and hygienic applications.

2.3 Understanding seal system performance
2.3.1 Volume temperature effects (process temperature effects)
Fill fluids expand or contract with temperature changes, creating a volume change that is absorbed by
the diaphragm seal and is seen as back pressure at the transmitter. This back pressure creates a shift in
the transmitter reading. For symmetrical or balanced systems, this error is usually minimal due to the
back pressure being equal on both sides. However, head temperature effect is still present.
Note
Other factors that affect seal temperature effect include diaphragm thickness, seal type and size,
capillary length and inner diameter.

2.3.2 Density temperature effects (head temperature effects)
Density temperature effect is due to the change in specific gravity of the fill fluid caused by a change in
ambient temperature. When installed, the weight of the fill fluid will produce an initial pressure read by
the transmitter, equaling the height between the high and low connection taps multiplied by the fill
fluid's specific gravity. As ambient temperature changes, the fill fluid specific gravity will change causing
the weight of the fill fluid to change, thus changing the pressure read by the transmitter. Density effect
will be seen in both

2.3.3 System time response and performance
The time response of a system is based on the type of transmitter, its sensor range, the length and inner
diameter (ID) of the capillary, and the viscosity of the fill fluid (which is directly affected by the process
and ambient temperatures). These factors all play a role in the overall performance of any seal system.
The relationship between system time response and temperature error is illustrated in Figure 2-4. It can
be seen that changing the capillary ID has an inverse affect between the time response and temperature
effect of a capillary system. As the capillary ID is increased, the time response of the system decreases
while the temperature effect increases.

2.4 Balanced vs. Tuned-System assemblies
A balanced remote seal system is a symmetrical system that utilizes equal seals and capillary length on
the high and low pressure sides of the transmitter. Since the capillary lengths are the same, each side
ideally has the same amount of fill fluid, minimizing or completely eliminating the seal temperature
effect due to equal pressure on both sides of the transmitter diaphragm. The balanced systems are still
affected by the head pressure as shown in Figure 2-5.

Tuned-Systems assemblies are asymmetrical remote seal systems with one seal directly mounted to the
high side of the differential pressure transmitter, and the other side connected to a seal via capillary.
Another possible Tuned-System assembly is any remote seal system with unequal lengths of capillary or
two different remote seals on the high and low pressure connections. Due to the unequal lengths of
capillary, there are seal temperature effects. However, this seal temperature effect counters the head
pressure from the oil-filled capillary and reduces total temperature effects on the entire system.

2.5 Specifying the right solution for vacuum applications
2.5.1 Vacuum application overview
When a vessel is operating in a vacuum (negative gauge pressure), it is important to specify the correct
transmitter remote seal system to measure level accurately and reliably. Failure to do so can result in
output drift or complete system failure. The combination of high process temperature and vacuum
process pressure conditions creates additional requirements when specifying the transmitter remote
seal system.
2.5.2 Vacuum applications
There are three primary transmitter-seal system components necessary to successfully specify vacuum
application solutions:
Seal system construction
Fill fluid selection
Transmitter mounting position
2.5.3 Seal system construction for vacuum applications
Emerson™ offers welded-repairable or all-welded vacuum system construction styles on diaphragm seal
assembles.
The all-welded vacuum construction was designed specifically for vacuum applications. In this
construction, the sensor module gaskets are removed and a disk is welded over the sensor isolators. This
eliminates the possibility of air being drawn into the seal system in deep vacuum conditions. This
premium design is strongly suggested for vacuum pressures below 6 psia (310 mmHga).
2.5.4 Transmitter mounting position
Mounting the pressure transmitter at or below the bottom vessel tap is an important factor to ensure a
stable measurement with vacuum applications. The static pressure limit for a differential pressure
transmitter is 0.5 psia (25 mmHgA), which ensures the transmitter sensor module fill fluid remains
within the liquid phase of the vapor pressure curve.
If the vessel static limit is below 0.5 psia, mounting the transmitter below the bottom tap provides a
capillary fill fluid head pressure on the module. A general rule is to always mount the transmitter
approximately 3 ft. (1 m) below the bottom tap of the vessel.
2.5.5 Fill fluid selection
When the process is under vacuum conditions, the fill fluid can vaporize at a lower temperature than
when it is under normal atmospheric or greater pressure. Each fill fluid has a specific vapor-pressure
curve. The vapor-pressure curve indicates the pressure and temperature relationship where the fluid is in
a liquid or a vapor state. Proper seal operation requires the fill fluid to remain in a liquid state.

For vacuum applications, specify fluids that are specifically designed for use in these types of
applications such as Silicone 704 for vacuum applications, Silicone 705 for vacuum applications, or
UltraTherm

2.6.2 Seam weld design
A seam weld design is used when the upper housing material is different from the diaphragm material.
The seam welded design has a hermetic weld at the inner diameter of the diaphragm and a TIG weld at
the outer edge. The diaphragm floats on the upper housing over the gasket surface area and could tear if
a metallic gasket were used.

2.6.3 Brazed design

This option is used with Tantalum diaphragm when a metallic gasket is required.

2.7 Differences between electronic remote sensors and capillary systems
Rosemount 3051S Electronic Remote Sensors (ERS™) System technology utilizes two Rosemount 3051S
Pressure Transmitters connected via an electrical wire instead of a single pressure transmitter with
remote seals and capillary tubing. As the Rosemount 3051S ERS System calculates the differential
pressure between the two transmitters, capillary tubing is not needed, and thus eliminates all head
temperature affects on the system. Seals are not required, but may still be necessary on certain
applications that include high temperature, corrosive, or viscous processes. For more information, refer
to the Rosemount 3051S Series Product Data Sheet

2.8 Instrument Toolkit: seal ordering and application process
Rosemount Instrument Toolkit Software is an instrumentation specification tool that can be used to
assist in product selection. This program analyzes application and process conditions against a
configured Rosemount model number and calculates the total system performance including expected
head and seal temperature effects and system response times.

2.9 Rosemount Thermal Range Expander: proper use and applications
Figure 2-8. Rosemount Thermal Range Expander
The Rosemount Thermal Range Expander increases the application range where DP Level technology can
be used by expanding the ambient and process temperature ranges of the system.
Traditional remote seal systems are filled with a single fill fluid to operate in applications with varying
ambient and process conditions. Silicone 704 and 705 are commonly used fluids for hot process
applications going above 570 °F (300 °C); these fluids must be kept above 32 °F (0 °C) and 68 °F (20 °C),
respectively, in order to properly transmit the pressure signal to the transmitter. This can prove to be
difficult for outdoor installations where extremely cold ambient conditions cause these fill fluids to gel.
The Rosemount Thermal Range Expander is a seal system that uses two different fill fluids to extend the
operating temperature range of the system. A high temperature fill fluid, which is next to the hot
process, is kept warm enough to stay responsive. A second fill fluid, located on the other side of the
intermediate diaphragm, operates over a wide ambient temperature range. The Rosemount Thermal
Range Expander can operate in ambient temperatures as low as –75 °C (–103 °F), and process
temperatures up to 410 °C (770 °F). This improves response time up to 46 percent and eliminates the
need for mechanical heat tracing.
The Rosemount Thermal Range Expander can be used with any Rosemount 3051S DP Level configuration
including Balanced Systems, Tuned-System Assembles, Electronic Remote Sensors (ERS), or direct
mounted to a transmitter.

Understanding Remote Seal Systems
Figure 2-12 shows the process and ambient temperature limits for the thermal optimizer with Silicone
704 and Silicone 705 Fill Fluids respectively. The shaded areas represent the temperature limitations;
applications outside of the shaded area cannot be used with a thermal optimizer.
For example, an application with an ambient temperature of 50 °F (10 °C) and a process temperature of
300 °F (149 °C) is within the limits, a thermal optimizer can be used in this application.
However, an application with an ambient temperature of 120 °F (40 °C) and a process temperature of
464 °F (240 °C) is outside of the limits. These high temperatures would be detrimental to the transmitter
electronics.
The submersible seal consists of a bellows-style seal and is designed for measuring level in top-down
applications with small tank connections, specifically 1.5-in. NPT threaded connections or 2- to 4-in.

in the process as shown below. Traditional DP Level seal systems are side mounted to tanks such that the
diaphragm seal is the only wetted material that comes in direct contact with the process fluid.
This assembly can only be ordered with Rosemount in-line transmitters for gage measurements.
Differential and absolute measurements are not available.

information on these seals.
3.1 Seals handling and installation
3.1.1 Diaphragm
The remote seal diaphragm is designed to withstand pressure and wear from process, but outside of
process connection conditions, remote seals are delicate and should be handled with care.
The protective cover should remain on the seal until the moment before installation. Try to avoid
touching the diaphragm with fingers or objects and refrain from setting the diaphragm side of the seal
down on a hard surface.

Even minor dents or scratches in the diaphragm material may impair the performance of the seal system
assembly. Care should be taken to ensure the seal diaphragm is not dented or damaged during seal
installation.
3.1.2 Capillary
When unpacking or handling seal system assemblies, do not lift the seal or transmitter by gripping the
capillaries. Avoid sharply bending or crimping the capillary tubing. The minimum bending radius of the
capillary tubing is 3-in. (8 cm).
3.1.3 Rosemount Thermal Range Expander
The Rosemount™ Thermal Range Expander system uses the heat from the process in order to keep both
fluids within the system functioning properly; therefore insulation is not always required. However, it is
always best practice to insulate systems to keep them functioning with optimum performance. The
Rosemount Thermal Range Expander should never be insulated above the line marked on the seal itself.

“Do Not Insulate
Above this Line”

3.1.4 Heat tracing
When using heat or steam tracing, exercise caution if PVC coating is added onto capillary, as PVC coating
should not be exposed to temperatures above 212 °F (100 °C) to avoid the possibility of thermal
breakdown.
Best practice for heat and steam tracing is to regulate the temperature slightly above the maximum
ambient temperature for a consistent result. To avoid accuracy effects and thermal stress, the capillary
should not be partially heated.

Reference Manual

NEVER attempt to disconnect the seals or capillaries from the transmitter or loosen bolts. Doing so will
result in loss of fill fluid and will void the product warranty.
Failing to recognize incorrect materials during installation may cause process leaks, which can result in
damage to the diaphragm seal system or death and/or serious injury to personnel. Proper wetted
material is required for specific process materials.
3.2 Gaskets
When installing remote seal systems which employ a gasket or a gasket and flushing connection ring,
make sure the gasket is aligned properly on the gasket sealing surface.
The user is responsible to ensure the gasket used does not exceed the temperature limits of the process.
Failure to properly install the gasket may cause process leaks, which can result in death or serious injury.
In addition, make sure the gasket does not press down upon the diaphragm face. Anything pressing on
the diaphragm will be read by the transmitter as pressure. A misaligned gasket may cause a false reading.
Installation
May 2017
The intermediate gasket between the seal and lower housing is supplied when the lower housing or
flushing connection is provided. The default gaskets are listed in Tab l e 3 -1 based on seal type. The
process gasket must be supplied by the end user. Tantalum diaphragms are not supplied with default
gasket, so a gasket option must be selected when applicable.
If a lower housing is supplied, then the following gaskets are the default gaskets for each seal unless
another gasket option is selected.

Note
The end-user is responsible for choosing a gasket and ensuring the process temperature does not exceed
the temperature limits of the gasket used. Failure to properly install the gasket may cause process leaks,
which can result in death or serious injury.
3.3 Tagging
Each remote seal system is tagged in accordance with the end-user requirements.
The remote seal model number is identified on the transmitter label, shown in Figure 3-2, 3-3, and 3-4.

The maximum working pressure (MWP) of the seal system assembly is stamped on the transmitter neck
tag. This can be dependent upon the maximum pressure rating of the seal system or transmitter upper
range limit.
