UTS™ – Ultrasonic Tank Switch

Picture 044

Universal Level Switch UTS™ has extended operating temperature range from –200°C to +450°C and is designed for level detection in cargo holds, wells & service tanks in sea and river ships, oil tankers, chemical tankers, gas carriers, offshore drilling platforms.

Ultrasonic Tank Switch UTS™ is made of stainless steel and is used for level detection of liquids in vessel tanks, storage tanks, bilge water tanks, cofferdams as well as for control of water ingress to vessel’s compartments.

The operating principle of UTS™ is based on a breakthrough patented acoustic wave technology, providing outstanding results in extreme operating temperatures. Accuracy of measurement is ensured regardless of shape of tank, type of liquid or liquid temperature.

UTS™ is installed outside the tank/pipe with only a metal rod inside the tank/pipe. Acoustic waves in the metal rod created by piezo-electric transducer ensure transmission of signals. When liquid in the tank reaches the probe on the rod, the emission of sound waves is muffled. This change is picked up by the piezoelectric transducer and a signal is transmitted to the corresponding alarm. Having only the metal rod inside the tank and no mechanical or moving parts means no maintenance is required.

UTS™ can be easily installed in vertical, horizontal or any inclined position and is tested for operation in a wide range of media, such as water, oil, petroleum, petrochemicals, acids, wastewater as well as many others. Made of high-grade stainless steel, UTS™ can also be used in tanks and reservoirs with food products.

UTS™ can be installed indoors as well as outdoors, including explosive environments and harsh arctic conditions.

UTS™ is characterized by high resistance to sticky products, high robustness and shock resistance and increased reliability under dynamic load and vibrations due to reinforced rod and electronic unit of new generation. UTS™ is also supplied in a special “Arctic” version, for applications in harsh environments with ambient temperature of down to –60°C without heating the device.

API UTS™ Features:

  • Any type of liquid
  • Only steel rod inside the tank (electronics and connections outside)
  • Fully welded construction
  • No moving parts
  • Extended temperature range
  • No maintenance required
  • Automatic self test
  • No calibration needed
  • Explosion proof
  • Pre-adjustable alarm points
  • No sensitivity to foam
  • More than 300 possible variations

TLA™ – Tank Level Alarm

tla_02_2012_fritTLA™ – Tank Level Alarm is used for detection of high (95%) and high-high (98%) levels in tanks. 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 high level of accuracy, reliability and customizability.

TLA™ represents a two-point level switch with alarm levels defined by length of rods, which are produced on request. Built-in test buttons are used for performing functionality test before filling in the liquid, in accordance with requirements of classification societies. Being highly adjustable to customer’s requirements, TLA™ can also be supplied as a three-point version.

Scope of supply consists of a flexible metal hose 0.5m for connection to the metal pipe, in which cable routing is laid on the deck.

TLA™ Features:

  • Works with any type of liquid and liquefied gas
  • Easy installation
  • No maintenance
  • No moving parts
  • No electronics inside the tank
  • No sensitivity to vapor, moisture and foam
  • Automatic self test
  • Lengths on request
  • Only steel rod inside the tank (electronics and connections outside)

TGD™ – Tank Gauging Device

TGD™ – Tank Gauging Device – a multifunctional deck sensor is designed for simultaneous measurement of level, temperature (up to 15 points), pressure and density (option) in cargo tanks of tankers, gas carriers, floating storages, FSO, FPSO, offshore drilling and fixed platforms, onshore oil, petroleum products and liquefied gas storage tanks.

Depending on the application type, TGD™ can be supplied as a 1-channel (level or temperature measurement), 2-channel (level + temperature; temperature + density), 3-channel (level, temperature and pressure/density) or 4-channel version (level, temperature, pressure and density).

Operation principle of TGD™ is based on the patented principle of Guided Low Frequency (GLF™) wave propagation,
which allows equally precise measurements along tank height with any shape of tank and type of liquid.

Principle and Advantages of GLF™ Technology:

  • GLF technology measures difference in density between air and liquid.
  • Tank geometry and objects inside the tank, such as ladders, heating pipes, etc. do not affect the signal.
  • GLF technology secures equal measurement accuracy of the whole tank – from top to bottom.
  • Automatic calibration with accuracy of 1mm every 2 seconds.
  • GLF technology is not affected by foam.
  • GLF technology allows a reduced number of sensors to be installed in tank.
  • Flexible solution with possibility for waveguide to be bent/curved.

TGD™ Features:

  • Automatic calibration
  • High level of accuracy
  • Less cabling – only 2 wires
  • No moving parts – longer lifetime
  • Flexible and easy installation
  • Explosion proof

UPT™ – Universal Pressure Transmitter

upt UPT™ – Universal Pressure Transmitter is used for measurement and detection of 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.

Housing and membrane of UPT™ are made of stainless steel. 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.

UPT™ can be specially designed for IP 68 applications and it meets the highest standards and extended requirements for arctic and cold climate operations within industrial equipment, marine and off-shore applications.
