• 2 wire instrument with HART digital communication
• Up to 10 m measurement range
• Wide temperature range of –40 to 85 °C
• Accuracy of ±2 mm (0.08 in) or 0.2 % of full span (the larger of the two)
• Beam angle as low as 5° with false echo filtering for narrow spaces • Easy installation with graphic echo display, advanced diagnostic and easy setup menu
• Unique GAP technology ensures the best performance under any conditions • IP66/67/68 and NEMA 4X (can submerge to 2 m depth for 24 hours)
• ATEX, IEC & FM Intrinsic safe and non sparking approved
The perfect fit for all water and waste water applications
• LST300 is made from metal and PVDF, and is resistant to corrosion, even if the whole instrument gets in contact with chemicals.
• LST300 automatically adapts to process conditions using unique GAP technology. It is the only product that works even in conditions with some vapor.
Storage, lagoons & settling ponds
• Easy setup of functional level measurement using the quick start menu. • Familiar and easy-to-learn menu structure for anyone who has used other ABB instruments.
• Direct interaction with the instrument without opening the front window cover, using ABB’s innovative and unique Through The Glass (TTG) technology.
Process basins including aeration, chlorine contact, skimmer tanks, sedimentation and flotation thickeners
• With advanced diagnostic functions such as detailed signal quality tracking and noise level diagnostics, LST300 replaces remote instruments as the most easy to install level transmitter.
• Works easily in the presence of turbulence and foam using unique GAP technology
Irrigation, plant inlet and final discharge
• Built-in equations and supporting software for open channel flow save you from doing the math manually.
• Class leading 2 mm (0.08 in) accuracy with temperature compensation ensures accuracy at all temperature ranges.
• Totalizer counts up to 10 million, keeping accurate track of the total flow over the device lifetime or the flow over an interval for your channel.
Wet wells, lift stations and pumping stations
• Immune to noise caused by the presence of heavy equipment such as like variable speed drives, LST300 is the perfect choice for pumping stations. • Market leading beam angle of 5° ensures easy installation and effective operation in narrow spaces.
• LST300 false echo filtering algorithm filters false echoes fro
• The entire LST300 is submersible in water, thus it can survive flooding conditions.
