1 Safety instructions
1.1 Designated use
The Float Tank Gauge LT5-1 perform an important role in all areas of industry. Many years of opera-
tion in wide variety of applications have proven their reliability. No electrical power is required to per-
form the measurement. In addition, LT series can be installed easily in your site and can measure the
liquid level accurately, and can be used for the detector of the remote command. Therefore LT series
are best suited for use in the following operations.
•Management of Inventory
•Batch Process
•Management of Process Tank
•Safety Drive of Tanks
1.2 Installation, commissioning, and operation
•Mounting, electrical installation, start-up, and maintenance of the instrument may only be per-
formed by trained personnel authorized by the operator of the facility.
•Personnel must read and understand these installation instructions before performing the proce-
dures.
•The instrument may only be operated by personnel who are authorized and trained by the operator
of the facility. All instructions in this manual must be observed.
•The installer must make sure that the measuring system is correctly wired according to the wiring
diagrams. The measuring system must be grounded.
•Observe all law and regulations applicable and valid for your country and pertaining to the opening
and repairing of electrical devices.
•Always be sure to wear gloves when installing any device.
1.3 Operational safety
Changes or modifications other than those expressly approved by Endress+Hauser
are strictly prohibited. Unauthorized modifications can cause malfunction or dam-
age, resulting in serious injury or death.

2.3 Scope of delivery
It is extremely important to follow the instructions concerning the unpacking, transportation and stor-
age of measuring instruments provided in the chapter "3.1 Incoming Acceptance, Transportation, Stor-
age". Delivered Items vary depending on the product specifications (refer to "3.9 General View of Stan-
dard Drawings and Order Codes").

3.1 Incoming acceptance, transport, storage
3.1.1 Incoming acceptance
Check the packing and contents for any signs of damage.
Check the shipment, and make sure that nothing is missing and that the items match your order.
3.1.2 Transportation
•Follow the safety instructions and conditions of transportation for instruments in excess of 18kg
(40 lbs.).
•Do not lift the measuring instrument by its head (union or flange) during unpacking.
3.1.3 Storage
Pack the measuring instrument so that it is protected against impacts during storage and transporta-
tion. The original packing material provides the optimum protection for this.
The allowed storage temperature is -20 to +70 °C.

3.2 Installation location
Be sure to perform the following operation prior to installation of LT.
•LT series should be installed in a place where meter can be easily read.
•The float must be installed so it is positioned near the tank sidewall.
•In a spherical tank, the float must be installed so that it is positioned in line with the center of the
tank.
•When installing LT on tanks that have a dome roof with a steep incline, the float must be installed
so it is positioned in line with the center of the tank.
•Use an appropriate gasket on flange connection to maintain airtightness.
The float should be positioned as far from the tank inlet or stirrer as possible, so that
the waves, which caused by liquid inflow, do not directly impact the float. If there is
no choice but to position the float near an inlet or stirrer, install a wave guard to pro-
tect the float. If liquid flows into the tank abruptly, the float line may be severed.

3.4 Welding for gauge supporter
When welding the gauge supporter, refer to the diagram below. Pipe supporter is supplied by th cus-
tomer.
Distance between outer tank wall and gauge head (LT5-6 for high pressure) is 15 mm greater
than for that of LT5-1 (for low pressure) and LT5-4 (for medium pressure).

3.5 Guide pipe
3.5.1 Guide pipe material and installation
Most LT installations will require the use of guide pipes, excluding tank top or underground applica-
tions. Pipe supporters are generally used in three sections as follows.
•Gauge head to elbow
•Elbow to elbow
•Elbow to tank roof
•The guide pipe and guide pipe supporter must be supplied by the customer.
•Vending of guide pipe must be 5 mm (0.17 in) or less.
•Spacing between the guide and the sheave elbow must be 2500 mm (98.43 in) or less.
Figure 7: Attachment of guide pipe
Galvanized carbon steel pipe is recommended for use as guide pipes.
When application is for extremely corrosive gas, using stainless steel or hard PVC
pipe, containing a resin inner lining is recommended.

3.5.2 Guide pipe connection
•Use a PTFE sealing tape or gasket to maintain airtightness against gas or rain.
•Be sure connection between the guide pipe and the union is secure so that rain water does not enter
LT5 from the union connection.
•Be sure that threaded connections are properly threaded to avoid a distorted or bent connection,
and be sure that welded connections are straight with no burrs left on the inside.

3.8 Length of measuring tape and wire
The lengths of the measuring tape and wire are longer (extra length) than the actual measurement
length and vary depending on each option. The following tables show the actual lengths according to
options in 060 for each option of specification 070. However, note that the maximum length that can
be displayed on the display of the LT5 gauge head simply corresponds to the measurement range. See
the following tables and select the appropriate length accordingly.
In case of Feature 070 is:
1. Measuring tape SUS316, CRT
2. Measuring tape SUS316, tank top installation
3. Measuring tape SUS316, seal pot/BT
