ABBe LST300 Ultrasonic Level Transmitter - Product Description
The ABBe LST300 Ultrasonic Level Transmitter is a cutting-edge non-contact measurement device designed for precise and reliable level monitoring of liquids and solids in industrial storage tanks, silos, and open-channel applications. Utilizing advanced ultrasonic technology, it delivers accurate real-time data across industries such as water and wastewater treatment, oil and gas, chemical processing, and food and beverage production. Its robust design, coupled with intelligent diagnostics and flexible communication protocols, makes it a versatile solution for challenging environments.
Core Technical Performance
The LST300 operates over a measuring range of 0.25 meters to 15 meters (0.8 to 49 feet), with a resolution of ±1 mm and an accuracy of ±0.5% of the measured value. It functions effectively in temperatures ranging from -40°C to +80°C (-40°F to +176°F), ensuring performance stability in extreme climates. The device is powered by a 12-30 V DC supply and provides multiple output options, including 4-20 mA analog signals and HART® 7 or WirelessHART® digital communication for seamless integration into modern control systems. Its 50 Hz update rate enables real-time monitoring of dynamic processes, such as rapidly filling tanks or fluctuating open-channel flows.
Innovative Design and Durability
Constructed with a 316L stainless steel housing and IP66/IP68 protection, the LST300 withstands harsh conditions, including exposure to dust, heavy rain, and temporary submersion. The sensor's PTFE transducer face resists corrosion from aggressive chemicals, acids, and solvents, while the dual-compartment electronics design isolates sensitive components from thermal shocks and vibrations. For hazardous areas, explosion-proof variants comply with ATEX/IECEx Ex d IIC T6 Gb standards, certifying safe operation in Zone 1/21 environments with flammable gases or dust.
Advanced Functional Capabilities
Non-Contact Measurement: Ultrasonic pulses emitted by the transducer reflect off the medium's surface, eliminating physical contact and reducing maintenance needs in corrosive, viscous, or sanitary applications.
Intelligent Echo Processing: Adaptive algorithms filter out false echoes caused by foam, turbulence, or internal obstructions, ensuring reliable data even in complex tank geometries.
Built-In Diagnostics: Continuous self-monitoring detects issues such as transducer fouling, cable faults, or signal attenuation, triggering alerts via HART® or control system interfaces.
Multi-Variable Output: Measures level, volume, and flow rate (in open channels) with configurable linearization curves for irregular tank shapes.
Industry-Specific Applications
Water/Wastewater: Monitors reservoir levels, pump station wet wells, and chemical dosing tanks. Submersible models with anti-biofouling coatings prevent microbial growth in treatment basins.
Oil & Gas: Tracks crude oil storage levels in offshore tanks and detects overfill risks in refineries. ATEX-certified units ensure safety in hydrocarbon processing zones.
Chemical Processing: Measures aggressive liquids like sulfuric acid or caustic soda in reactor vessels, with PTFE components resisting chemical degradation.
Food & Beverage: Complies with hygienic standards (EHEDG) for level control in sugar silos, brewing tanks, or dairy processing vessels.
Certifications and Compliance
The LST300 meets global standards, including SIL 2 (IEC 61508/61511) for safety-critical systems, EN 61326-1 for electromagnetic compatibility, and NEMA 4X for outdoor durability. It is certified for use in potable water applications per WRAS and ACS schemes.
Competitive Advantages
Ease of Installation: Tool-free mounting brackets and intuitive setup via local display or ABBe's FieldCare™ software reduce commissioning time.
Energy Efficiency: Consumes 0.8 W in standard operation, ideal for solar-powered remote installations.
Long-Term Reliability: Maintenance-free operation with a 10-year MTBF (Mean Time Between Failures) minimizes lifecycle costs.
Optional Accessories
Sun Shield and Cooling Fins: Mitigate solar heating effects in desert or high-temperature environments.
Remote Display Module: Provides on-site level readouts and diagnostics for hard-to-access locations.
Blast-Proof Enclosures: Protect the transmitter in explosive atmospheres (ATEX Zone 0/20).
