1 Safety instructions
1.1 Designated use
The Float Tank Gauge LT11/12 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 mea-
surement.
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 operator 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.

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.
