Level Aeran 2(LA2)employs unique technology to deliver high accuracy level readings for ballast tanks and drafts. Unlike most conventional pulse purge systems, LA2 uses a set of micro-computer controlled solenoid valves to regulate air supply, pressure during measurement, and atmospheric pressure adjustments. By intermittently stopping the flow of air during measurement for a steady pressure, LA2 achieves an accuracy of ±50mm at full scale. In addition, the system overall requires less air - and less energy – than other systems. A higher pressure purge of air during each cycle also helps keep the purge mouth free of clogs, resulting in lower maintenance requirements. The compact control box can be outfitted for up to 24 gauges, but still takes up little room.
