Floats
SoClean®transmitters offer numerous floats for different applications
such as stainless steel, 3-A sanitary, Hastelloy®, Teflon, and Nitrophyl
for both product level and interface level. To be able to accurately
detect the interface level there needs to be a difference of at least
0.05in specific gravities between the product and interface liquids.
For detailed information about floats, refer to the ‘Accessories
Catalog’ (MTS Part#551103).
For assistance with selecting a specific float for your application,
please contact technical support with the following information:
• Specific gravity of liquid(s) being measured
• Process temperature
• Process opening size
• Vessel pressure
SoClean®transmitters should be used with a float having an offset
weight and made of stainless steel or Hastelloy®C. This allows the
float to stay in contact with the pipe to prevent the buildup of an
electrostatic charge. Non-metalic floats with a projected surface area
of less than 5,000 mm² should only be used in Zone 0, Gas group
IIA such as float part numbers 201643-2, 201649-2, 201650-2,
201109, 251115 and 251116. All other non-metallic floats offered by
MTS such as, 251939, 251119 and 251120 should not be used in a
hazardous area application.
Internal electronics
All transmitters come with two electronic components of a sensing
element and a board set. Rigid sensing elements are standard on
SoClean®. Flexible sensing elements are available upon request. The
board set consists of up to three electronic boards and a display.
A temperature sensing function is optional with the SoClean®
transmitter. The temperature sensing device is a Digital Thermometer
mounted inside the transmitter’s outer pipe assembly. The SoClean®
can be ordered with 1, 5, 12, or 16 temperature points.
Display
All LP-Series liquid level transmitters are shipped with a stylus (MTS
Part # 404108) to be used for manipulating the display. For single and
dual cavity housings, the stylus is designed to allow for programming
of the unit without removing the housing. When using the stylus make
sure to align the stylus with the shape outline around the buttons in
the same orientation. Failure to correctly align the stylus can cause the
display to not function properly. Password for entering the menu is
27513. For additional details consult the protocol specific Modbus
Interface Manual (MTS Part #551700), DDA Interface Manual (MTS
Part #551701), and HART®Interface Manual (MTS Part #551702).
Accessories
MTS also offers a series of displays, housings, converters, and
other accessories, please refer to the ‘Accessories Catalog’ (MTS
Part#551103).
5.2 Accuracy
For magnetostrictive transmitters inherent accuracy is measured
in terms of non-linearity. Non-linearity is a measurement of any
imperfections in the waveguide that are reflected in the linearity of
the transmitter’s output. MTS tolerances reflect a maximum non-
linearity of ±1mm. MTS is able to achieve such strict tolerances by
manufacturing all of its own waveguide from a proprietary alloy and
testing 100% of all transmitters before shipping.
5.3 Warranty
Important:
Contact Technical Support or Customer Service for assistance if
you suspect that the transmitter is not working correctly. Technical
support can assist you with troubleshooting, part replacement, and
Returned Material Authorization (RMA) information if required.
All Level Plus®transmitters come with a two year limited warranty
from the factory shipment date. An additional extended warranty can
be purchased. A Return Materials Authorization (RMA) number is
required and must accompany any transmitter returns. Any unit that
was used in a process must be properly cleaned in accordance with
OSHA standards, before it is returned to the factory. A Material Safety
Data Sheet (MSDS) must also accompany the transmitter that was
used in any process.
5.4 Storage
If storage is required prior to installation, store indoors in a dry
environment at ambient temperature range not to exceed −40…+71°C
(−40…+160°F).

6. Installation and mounting
6.1 Training
Warning:
When the pipe/hose of the LP-Series level transmitter is installed or
removed from the tank the release of flammable vapors will occur.
Take all necessary precaution when installing or removing the level
transmitter due to the release of flammable vapors.
Installation should only be conducted by qualified service personnel
according to IEC 60079-14 and local regulations or MTS trained
service technicians. MTS offers web based and in person training
for installation, commissioning, maintenance, and repair. MTS also
offers factory direct services for these same functions. Contact MTS to
discuss training or factory direct services before starting.
6.2 Stilling wells and guide poles
Level Plus®transmitters can be mounted in slotted or unslotted stilling
wells but a slotted stilling well is always preferred. Using a unslotted
stilling well will negatively affect performance of any level device as
the level in the stilling well can differ from the level in the tank. The
Level Plus®transmitter can also be installed to one side of the stilling
well to also allow for sampling and manual gauging from the same
opening as the automatic tank gauging. Contact technical support for
details.
Level Plus®transmitters do not require a stilling well for installation.
Our transmitters are installed in numerous tanks without stilling wells
with no loss in performance due to our patented flexible waveguide
and hose. A stilling well is highly recommended for agitated, turbulent,
and/or fast filling tanks.
6.3 Tools
• Channel Lock pliers
• Common head screwdriver, slotted screwdriver
• 3/4" Open End wrench
• Phillips head screwdriver, plus screwdriver
6.4 Installation steps
Caution:
It is recommended that assembly and mounting of this transmitter
should not be done alone. To ensure proper and safe assembly of
the SoClean®transmitter, a minimum of two (2) individuals are
recommended. Gloves are also recommended. PPE may be required
for work areas such as safety shoes, safety glasses, hard hat, and
fire resistant clothing.
1. Consult chapter 4.3 before starting.
2. Perform steps 1-10 in chapter 8.4.1 for Modbus or DDA. Perform
steps 1-9 in chapter 8.4.2 for Analog.
3. For CP end plug, remove hitch pin and install float. For DN end
plug, install float but be careful as float is not retained and will fall
off. For TB and DP end plugs, the float is already installed. Secure
the Tri-Clamp onto the mating connection on tank.
4. Tighten the Tri-Clamp to hold the transmitter in place.
5. Terminate the field wire cables noting proper wire orientation.
6.5 Mounting
The method of mounting the transmitter is dependent on the vessel
or tank in which it is being used, and what type of transmitter is being
mounted. There are two typical methods for mounting; threaded flange
mounting and welded flange mounting.
Threaded flange mounting
In some applications, the SoClean®transmitter can be mounted
directly to the tank or flange via a NPT or BSPP threaded fitting,
assuming there is a proper threaded connection available. If the float
will not fit through the flange opening when the flange is removed,
there must be some alternative means to mount the float on the
transmitter from inside the vessel; this may require an access port
nearby the entry point of the transmitter as shown in Fig. 8.

Tri-Clamp mounting
The SoClean®transmitter can also be mounted to a Tri-Clamp as
shown in Fig. 10. First, install float(s) onto the transmitter. Second,
install the float retaining hardware on the tip of the transmitter. To
complete the installation, mount the transmitter, Tri-clamp and float(s)
as a unit in to the tank.

7. Electrical connections
7.1 Basic information
A typical intrinsically safe connection for the Level Plus®SoClean®
transmitter includes protective safety barriers, a power supply and a
reading or monitoring device. Refer to Agency information in chapter
13.
A typical Explosionproof/flame proof connection for the Level Plus®
SoClean®transmitter includes a power supply and a reading or
monitoring device. All cabling is in approved conduit with sealoffs
as specified by local electrical code. Refer to agency information in
chapter 13.
7.2 Safety recommendations
Be sure to:
1. Always follow applicable local and national electrical codes and
observe polarity when making electrical connections.
2. Never make electrical connections to the Tank Slayer®transmitter
with power turned on.
3. Make sure that no wire strands are loose or sticking out of
the terminal block connection which could short and cause a
problem.
4. Make sure that no wire strands, including shield, are in contact
with the electronic module enclosure.
5. The electronics module enclosure is grounded through internal
circuitry and is electrically isolated from the explosionproof
housing.
7.3 Industrial topologies
There are four topologies described and illustrated below. However,
the daisy chain topology is not recommended by MTS.
Point-to-point
The point-to-point topology consists of having only one device on the
loop as shown in Fig. 9. This topology is not usually used with a bus
network since it does not take advantage of placing multiple devices
on a loop.
PLC

I14 I
Fig. 11: Bus with spurs topology
PLC
Fig. 12: Tree topology
Fig. 13: Daisy-chain topology
Tree alignment
The tree topology is very similar to the bus with spurs topology with
the main difference of having a common junction box for all of the
transmitters as shown in Fig. 12. Bus with spurs and tree topologies
can also be used together to form a hybrid topology.
Daisy chain
The daisy-chain topology utilizes a single cable that is connected to
all of the transmitters with the cable being interconnected at each field
device. When using this topology make sure that the wiring practice
allows for one transmitter to be disconnected without disconnecting
the entire loop as shown in Fig. 13. MTS does not suggest using the
daisy-chain topology.

5. For Division Installations, an approved conduit seal is required
within 457 mm (18 in.) of the enclosure.
6. For Zone Installations, an approved conduit seal is required within
50 mm (2 in.) of the enclosure.
Bus with spurs
The bus with spurs topology has a main trunk cable that has each
device connected via its own spur at a junction box as shown in Fig.

7.6 Grounding
7.6.1 Safety grounding
Warning:
Grounding the transmitter through a threaded conduit connection
does not meet the requirements as a grounding of the sensor for
safety.
There are two methods to provide an earth ground connection to
the earth ground of the electronics. Either method must result in a
resistance of less than 1 Ω.
• Run an earth ground through the conduit and connect directly to the
earth ground lug inside the housing.
• Run an earth ground directly to the ground lug on the outside of the
housing.
7.6.2 Shield grounding
Warning:
The shield ground does not meet the requirements as grounding of
the sensor for safety.
Immunity performance of the sensor from external sources of
surge, burst, RF, radiated emissions and other noise is dependent
on a proper ground for the shield of the communications cable.
The communications cable shield should be of a braided type and
connected to the internal ground lug of the sensor housing.
Runs in a continuous metallic conduit
When installed inside a dedicated continuous metallic conduit,
the conduit provides a level of shielding protection from external
interference and a level of ground to the sensor housing. In this case
a foil type shielded cable with a drain wire connected to the internal
ground lug may be sufficient. Sharing of the metallic conduit with
other cables will result in loss of effective shielding performance of
the communication cable and possible degradation in performance
of the sensor. In this case a braided type shielded cable connected to
the sensor internal ground lug would be recommended. In all cases
paralleling the communications cable with any noise generating cable
inside of a conduit or with noise generating cables in close proximity
to the conduit may degrade the performance of the sensor.
Runs without a conduit
In some rare applications, or where safety may not be required, a
metallic conduit may not exist. The communications cable shield
should be of a braided type and connected to the internal ground
lug of the sensor housing. Alternatively a safety approved EMC
Cable Gland can be used for grounding the shield. Contact MTS for
information before using one of these cable glands.
NEC
Undesirable currents (ground loops) is a violation of the NEC and is a
safety hazard.
