ABB LST200 ultrasonic level transmitter
ABB has launched the LST200 ultrasonic level transmitter, designed specifically for industries with large installed bases of level measurement devices — particularly water and wastewater treatment. With a modular design and intelligent algorithms, the product should be easy to install, commission and maintain.
Commissioning is said to be easy due to a set-up menu that guides users through configuration within 1 min. It also has a blue backlight that makes it highly visible in strong sunlight or darkness in locations such as lagoons and settling ponds. Maintaining the device is made easy through real-time echo waveform and diagnostic messaging for efficient troubleshooting.
High stability is achieved by an algorithm that enables the device to detect and automatically compensate for any instability in the strength of the ultrasonic signal. This makes it suitable for process basins for aeration, chlorine contact, skimmer tanks, sedimentation and flotation thickeners, where there can be unstable surface echo from foam or turbulence.
An intelligent algorithm with noise filtering makes the product useful in wet wells, lift stations and pumping stations as it is immune to noise from heavy equipment such as variable speed drives. Temperature compensation offers accuracy that is better than ±3 mm or 0.25% of full span.
Submersible in water, the product can survive flooding. It has a waterproof rating of IP68, which is relevant for the water and wastewater industries. A non-contact instrument made from polycarbonate, it is resistant to process liquids such as mild acid and base, chloride and oxidiser.
