Tank Level Alarm
TLA™
The TLA™ (Tank Level Alarm) is used for the detection of
high (95%) and high-high (98%) levels in tanks. The TLA™
is installed on the deck of tankers, gas carriers, floating
storages, FSO, FPSO, onshore storage tanks for oil,
petroleum products and liquefied gases.
Built on the same patented acoustic wave technology as
UTS™, TLA™ features a high level of accuracy, reliability and
customizability.
The TLA™ represents a two-point level switch with alarm
levels defined by the length of rods, which are produced
on request. Built-in test buttons are used for performing
a functionality test before filling the liquid, in accordance
with the requirements of classification societies. Being
highly adjustable to customer’s requirements, the TLA™ can
also be supplied as a three-point version.
The scope of supply consists of a 0.5 m flexible metal hose
for connection to the metal pipe in which cable routing is
laid on the deck.
Main Advantages

liquefied gas
• E asy installation
• N o maintenance
• N o moving parts
• N o electronics inside the tank
• N o sensitivity to vapour, moisture and
foam
• A utomatic self-test

Universal Pressure Transmitter
UPT™
The UPT™ (Universal Pressure Transmitter) is used for
the measurement and detection of the pressure in tanks
and pipeline installations onboard or ashore, for level
measurement (hydrostatic method) in service, ballast and
slop tanks, as well as for draught measurement.
The housing and membrane of the UPT™ are made of
stainless steel. The UPT™ can be supplied with various
types of flange and thread connections, including a special
extension for installation on top of tanks and reservoirs.
Special attention has been given to meeting demands for a
high level of enclosure, robust, compact construction and
resistance to shock and vibration where conditions of high
overload and temperature variation are common.
The UPT™ is specially designed for IP68 applications and
it meets the highest standards and extended requirements
for arctic and cold climate operation within industrial
equipment, marine and off-shore applications.
Main Advantages
• G eneral purpose pressure transmitters
• E asy installation
• C ustomized solutions
• S uperior performance
• A pplication versatility
• P lug-in electronic module

Universal Temperature Transmitter
UTT™
The Universal Temperature Transmitter (UTT™) is used for
the temperature measurement of various media – water, oil,
petrochemicals, acids, alkalies, gases and steam.
The UTT™ is characterized by a reinforced housing
manufactured in stainless steel and the option of open-air
installation.
The option of ordering the sensor with the required probe
length, with or without a thermowell, in explosion-proof or
standard construction, with any thread or flange connection
makes the UTT™ the most convenient solution for most ship
applications.
Main Advantages
• G eneral purpose temperature transmitter
• E asy installation
• C ustomized solutions
• R esistant to aggressive media
• R esistant to temperature drop
• E asy connection to most interfaces
