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
