5.1 Components
The Level Plus®LLE liquid level transmitter consists of four main
components; a base model, float, adaptor, and optional temperature
measurement. Varying the components of the transmitter allows the
transmitter to be customized to almost any application.
Base Model
The base model of the LLE consist of the housing, 3/4” NPT threads,
M12 connector, and either a 7 mm or 10 mm pipe. The drawing of the
base model is shown in section 5.7 Technical Drawing.
Floats
LLE transmitters offer numerous floats for different applications such
as stainless steel 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’, (Temposonics 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
Adaptor
The LLE is available with multiple adapters to allow for mounting of
the standard 3/4” NPT fitting into larger openings. Available adapters
include NPT fittings from 1” to 4”, ANSI flanges from 1” to 6”, SAE 5
bolt adapters, and custom flanges.
Temperature Measurement
The LLE offers an optional temperature measurement for analog
outputs models with a direct RTD output from a PT100 Class A RTD.
The RTD is located at 2" from the tip of the pipe for order lengths less
than 20" and at 10% of order length for all other lengths.
Accessories
Temposonics also offers a series of displays, housings, converters,
and other accessories, please refer to the ‘Accessories Catalog’,
(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. Temposonics tolerances reflect a maximum
non-linearity of +/- 0.5 mm. Temposonics 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.
The Temposonics obligation is limited to repair or replacement of any
defective part of the unit. No warranty can be provided for defects
that are due to improper use or above average stress of the product,
as well as for wear parts. Under no circumstances will Temposonics

6. Installation and mounting
6.1 Training
Installation should only be conducted by qualified service person-
nel according to local regulations or Temposonics trained service
technicians. Temposonics offers web based and in person training for
installation, commissioning, maintenance, and repair. Temposonics
also offers factory direct services for these same functions. Contact
Temposonics 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
• Adjustable pliers
• Large pipe wrench
• Common head screwdriver, slotted 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 level 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
3. Remove stop collars from rigid pipe.
4. Slide NPT adapter or flange onto rigid pipe and secure the
adapter/flange. To prevent damage to rigid pipe keep the adapter/
flange supported and towards the end of the level transmitter.
5. Slide the product float onto the rigid pipe. Slide the interface float
(optional) onto the rigid pipe. Install stop collar so the magnet of
the float is 64 mm (2.5 in.) from the tip of the rigid. Do not drop
float(s) or allow them to free fall along the rigid pipe as damage
may result.
NOTICE
The bottom stop collar can be removed or adjusted based on the
float selected for the application. Please consult the factory for more
information.
6. Slide float(s) and adapter or flange assembly back down to the
stop collar to prevent them from free falling during installation
into the tank. If you are using the o-ring stop collar it will not
support the weight of the adapter or flange. Insert the rigid pipe
and floats through the tank opening and lower the transmitter
float assembly into the tank until it rests on the bottom.
7. Connect the adpter or flange to the mating connector on the tank.
8. Connect the 3/4” NPT (rigid) to the adapter or flange
assembly. Tighten the NPT fitting to the adapter or flange. It is
recommended to use anti-seize on the connection.
9. Connect cable to connector.
10. Terminate the pigtail cable noting proper wire orientation. Wiring
diagram is shown in Section 7.
Consult Section 5.7 Technical Drawing to reference what the finished
installation should look like.

Level Plus® LLE
Operation Manual
I14 I
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. For model LLE there is a NPT thread mount or flange mount.
NPT Threaded mounting
The level transmitter can be mounted directly to the tank via a NPT
threaded fitting, assuming there is a proper threaded connection
available as shown in section 5.7. If the float will not fit through the
opening, 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.
Drilled and tapped flange mounting
The level transmitter can be mounted directly to the tank using a
flanged opening. If the float will not fit through the flanged 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.

7. Electrical connections
7.1 Basic information
Placement of installation and cabling have decisive influence on
the sensor‘s electromagnetic compatibility (EMC). Hence correct
installation of this active electronic system and the EMC of the entire
system must be ensured by using suitable metal connectors, shielded
cables and grounding. Overvoltages or faulty connections can damage
its electronics despite protection against wrong polarity.
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 level transmitter with
power turned on.
3. Use low-resistant twisted pair and shielded cables. Connect the
shield to ground externally via the controller equipment.
4. Keep control and sign leads separate from power cables and
sufficiently far away from motor cables, frequency inverters, valve
lines, relays, etc.
5. Use only connectors with metal housing and connect the
shielding to the connector housing.
6. Keep the connection surface at both shielding ends as large as
possible. Connect the cable clamps to function as a ground.
7. Keep all non-shielded leads as short as possible.
8. Keep the earth connection as short as possible with a large cross
section. Avoid ground loops.
9. With potential differences between machine and electronics
earth connections, no compensating currents are allowed to flow
across the cable shielding. Recommendation: Install potential
compensating leads with large cross section or use cables with
separate double shielding, and connect only one end of the shield.
10. Use only stabilized power supplies in compliance with the
specified connecting values
NOTICE
1. Do not mount the sensors in the area of strong magnetic or
electric noise fields.
2.Never connect / disconnect the sensor when voltage is applied.

7.3 Grounding
Earth/Machine Ground
The LLE is earth grounded through the process connection to the
tank with the assumption that the tank is grounded. If the tank is not
grounded then a ground will need to be connected to the housing of
the LLE. Without correct grounding the overvoltage protection will be
compromised.
Shield Ground
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 communica-
tions cable shield should be of a braided type and connected to the
internals.

according to local regulations or Temposonics trained service
technicians. Temposonics offers web based and in person training for
installation, commissioning, maintenance, and repair. Temposonics
also offers factory direct services for these same functions. Contact
Temposonics to discuss training or factory direct services before
starting.
8.2 Tools
• Adjustable wrench
• Anti-seize
8.3 Inspection
Below are some standard items that should be inspected on a
regular basis to make sure that the level transmitter and surrounding
environment are in operating condition.
• There are no visible unauthorized modifications
• Electrical connections are tight
• No obvious damage to cable
• Housing is not damaged or cracked
• No corrosion on visible parts
8.4 Preventative maintenance
The level transmitters do not typically require preventative
maintenance but may require preventative maintenance dependent
on the application. For general purpose applications where there is
no potential for buildup on the pipe and/or float there is no need for
preventative maintenance but routine inspection is still suggested.
For severe service applications where there is potential for buildup on
the pipe and/or float then preventative maintenance is required.
8.4.1 General purpose applications
8.4.1.1
Perform Inspection suggested in chapter 8.3.
8.4.1.2
It is suggested to disconnect the process connection between the tank
and the level transmitter and anti-seize or similar lubricant to prevent
damage to threads.
8.4.1.3
No additional preventative maintenance is necessary. Preventative
maintenance suggested for Severe Service Applications may be
performed.
NOTE
It is best to clean the pipe as it is removed from the tank to minimize
the amount of product that is removed from the tank. The user
should take caution and abide by all regulations so that product is
not spilled and the environment is not contaminated.

11.2 IO-Link output
IO-Link is an open standard according to IEC 61131-9. It is a serial,
bi-directional point-to-point connection for signal transmission and
energy supply. The bi-directional communication enables consistent
communication between sensors and the controller as well as
consistent diagnostic information down to the sensor level. For
additional details on setup please consult the EH IO Link manual
551485 section 5.
The measurement direction of IO Link can be programmed by the
customer. The Parameter Measuring Direction, Index 0x73, can be set
to False to measure from the housing to the tip of the pipe or True to
measure from the tip of the pipe to the housing.
11.3 SSI output
The SSI output is available as either 24 or 25 bit, Binary or Gray code,
and 0.1 mm resolution. The measurement direction is set to measure
up from the tip of the pipe.
11.4 CANopen output
CANbus (Controller Area Network) is designed for high-speed data
exchange at machine level. CAN is a vendor independent open
fieldbus system, based on standard ISO 11898. CAN specifies the
functional and technical parameters with which the intelligent digital
automation devices can be networked via a master-slave serial link
by using a communication profile. Protocol architecture of functional
and applications data is oriented to the OSI reference model (ISO
7498). Bus technology is administrated and developed by the user
organisation CiA (CAN in Automation)
The CANOpen output of the LLE is avaialbe with or without integral
termination, selectable Baud rate of 1000, 500, 250, or 125 kBit/s.
