1 Safety instructions
1.1 Designated use
The Float Tank Gauge LT1100/1200 have been developed for use in all areas of industry. Many
years of operation in wide variety of applications have proven their reliability. No electrical power
is required to perform the measurement.
Typical application:
• Level indication of petroleum products such as crude oil, kerosene, light and heavy oil, vegetable
oil, palm oil, seed oil and animal oil.
• Highly viscous liquid such as asphalt
• Certain chemicals (corrosive/toxic vapor can be sealed using liquid seal pot)
1.2 Installation, commissioning and operation
• Mounting, electrical installation, start-up and maintenance of the instrument may only be carried
out by trained personnel authorized by the operator of the facility.
• Personnel must absolutely and without fail read and understand this Operating Instructions before
carrying out its instructions.
• The instrument may only be operated by personnel who are authorized and trained by the oper-
ator of the facility. All instructions in this manual are to be observed without fail.
• The installer must make sure that the measuring system is correctly wired according to the wiring
diagrams. The measuring system is to be grounded.
• Please observe all provisions valid for your country and pertaining to the opening and repairing of
electrical devices.
Caution!
Changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.
1.3 Return
The following procedures must be carried out before the instruments is sent to Endress+Hauser for
repair:
• Always enclose a duly completed “Declaration of Contamination” form. Only then can Endress
+Hauser transport, examine and repair a returned device.
• Enclose special handling instructions if necessary, for example, safety data sheet as per EN
91/155/EEC.
• Remove all residue which may be present. Pay special attention to the gasket grooves and crevices
where fluid may be present. This is especially important if the fluid is dangerous to health, e.g.
corrosive, poisonous, carcinogenic, radioactive, etc.
A copy of the “Declaration of Contamination” is included at the end of this operating manual.
Caution!
• No instrument should be sent back for repair without all dangerous material being completely
removed first, e.g. in scratches or diffused through plastic.
• Incomplete cleaning of the instrument may result in waste disposal or cause harm to personnel
(burns, etc.). Any costs arising from this will be charged to the operator of the instrument.
1.4 Disposal
In case of disposal, please separate the different components according to their material consistency.

3.1 Incoming acceptance, transport, storage
3.1.1 Incoming acceptance
Check the packing and contents for any signs damage.
Check the shipment, make sure nothing is missing and that the scope of supply matches your order.
3.1.2 Transport
Follow the safety instructions and transport conditions for instruments of more than 18 kg.
3.1.3 Storage
Pack the measuring instrument so that it is protected against impacts for storage and transport. The
original packing material provides the optimum protection for this.
The permissible storage temperature is -20...+70 °C.
3.2 Installation location
Note!
The LT 1100/1200 gauge head should be installed in a place where it is easy to read the scale.
Caution!
Tank enough space between the liquid inlet, agitator, and the float. Make sure the fluid entering the
tank will not hit the float directly.
If it is inevitable to install a float where it is facing the liquid inlet, setup a shield in front of the float
so that the wave will not directly hit the float.

3.5.1 Guide pipe material and installation
Pipe work would be required most of installation
except some tank top or under ground
applications. Basic pipe materials in three section
(gauge head to elbow, elbow to elbow, and
elbow to tank roof) and pipe support materials
are normarlly out of Endress +Hauser’s supply.
Caution!
• When choosing pipes, select either zinc plate
or stenless steel material.
• If you are using on extremely corrosive
substance, use either completed plating or
adhesive lining.
