5.1 Components
The Level Plus®LLH liquid level transmitter consists of three main
components; a base model, float, and process connection. Varying the
components of the transmitter allows the transmitter to be customized
to almost any application.
Base Model
The base model of the LLH consist of the housing, M18 threads, M12
connector, 10 mm inner pipe, 5/8” OD outer pipe, and pipe connection
fitting. The drawing of the base model is shown in section 5.7
Technical Drawing.
Floats
LLH transmitters offer numerous floats for different applications
such as stainless steel for product level. 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
Process Connection
The LLH is available with multiple connection types and sizes to allow
for mounting on the tank. The options include a 3/4" NPT fitting or a
Tri-clamp available from 1.5 to 6”.
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:

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, and hard hat.
1. Consult chapter 4.3 before starting.
2. Perform steps 1-10 in chapter 8.4.1
3. For pipe options C with T-bar end plug and D with DP end plug
the floats are captive and cannot be removed.
4. For pipe options E with Clean-in-Place end plug and F with DN
end plug the floats can be removed.
5. The pipe options E and F can be ordered with the 3/4" NPT fitting.
For this combination, remove the float and add adapter. Slide
adapter up the pipe and do not scratch the pipe. Place float on
pipe at the bottom.Do not drop float or allow it to free fall along
the rigid pipe as damage may result.
6. Insert the rigid pipe and floats through the tank opening and
lower the transmitter/ float assembly into the tank.
7. For Tri-clamp process connections, lower until the Tri-clamp rest
on the mating connection of the tank. Install Tri-clamp.
8. For NPT connections, connect the adapter to the tank. Position
level transmitter at desired height and tighten NPT fitting.
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® LLH
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 LLH there is a NPT thread mount or Tri-clamp
mount.
NPT Threaded mounting
In some applications, the model LLH transmitter can be mounted
directly to the tank or flange via a NPT 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. 3.
Tri-Clamp mounting
The model LLH can also be mounted to a Tri-Clamp as shown in Fig. 4.
Depending on the end plug the float may come on the level transmitter.
If not, install the float on the level transmitter. To complete the
installation, mount the transmitter, Tri-clamp and float as a unit into
the tank.

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.

Level Plus® LLH
Operation Manual
I16 I
7.3 Grounding
Earth/Machine Ground
The LLH 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 LLH. 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.

• 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
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.

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. 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.
9.2 Training
Repair should only be conducted by qualified service personnel
according to local regulations or Temposonics trained service
technicians. Temposonics offers web based and in person training for
installation, commissioning, maintenance, and repair. Temposonics

10. Spare Parts
Below are the spare parts list for the LP-Series shown as the display,
electronic module, sensing element, and flexible hose. Please contact
Temposonics Technical Support with any questions.
11. Interface
11.1 Analog output
The analog output for LLH is a single output The output codes
starting with V are voltage outputs and the codes starting with A are
current outputs. The first digit is the voltage or current closest to the
head and the second is closet to the tip. For example, A010 4..20mA
has the 4mA set point closest to the head and 20 mA closest to the tip.
The analog output cannot be adjusted.
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 LLH is avaialbe with or without integral
termination, selectable Baud rate of 1000, 500, 250, or 125 kBit/s.
The resolution is set at 0.02 mm and the output can be configured for
1 or 2 floats. The measurement direction is set to measure away from
the electronic housing and towards the tip of the pipe
11.5 Profinet RT & IRT
The model LLH is are available with PROFINET RT (Real Time)
and IRT (Isochronous Real Time). PROFINET IRT offers a
synchronized communication with a minimum cycle time of 250 µs.
For time-critical applications, linear extrapolation enables synchronized
controller communication for any stroke length of the sensor.
In addition to the measured position value via the PROFINET protocol
further data about the current sensor status, such like the total
distance travelled, the internal temperature and the total
operating hours, can be displayed for diagnostic purposes
For details on the Profinet RT & IRT output consult operation manual
551973 sections 5 and 6. The measurement direction by default is set
to measure away from the housing. The direction can be changed to
Reverse to allow for measuring away from the tip of the pipe
11.6 Ethernet/IP
The EtherNet/IP™ output supports CIP Sync™ (Common Industrial
Protocol) and DLR (Device Level Ring) capabilities. CIP Sync™ offers
synchronization between devices in an EtherNet/IP™ network, allowing
for increased control coordination in time-critical applications. DLR
capability provides a fault-tolerant network so that the sensor can be
used in ring connection topologies when reliable continuous system
operation is required.
