FloScan says its direct flow measurement systems are more accurate than algorithm-based techniques. Models are available for all makes of marine diesel engines up to 6000 hp in tugboats and workboats of all kinds for applications including propulsion engines, gensets, bow thrusters and other diesel-powered systems. Krill Systems, a provider of integrated onboard and remote vessel monitoring systems for yachts and commercial vessels, recently introduced their SmartTug software, a PC based software system that improves vessel efficiency and data communication in a highly competitive and cost conscious industry.
