UTS™ - Ultrasonic Tank Switch

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.
