A current meter measures the strength and, in some models, the direction of currents flowing around the vessel. It can be used to help determine potential drift.
ApplicationsThese devices are used at sea, in rivers and ports. Knowledge of the currents affecting a vessel facilitates maneuvers by allowing for corrections to counter their effects. Commercial fishing boats use them to determine currents at different depths in order to locate schools of fish.
TechnologiesSuch meters can be mechanical, electromagnetic or acoustic. Ships normally have acoustic models, which use the Doppler effect to determine current strength. They consist of transducers, a processor and a display screen. Three beams are necessary to determine the three characteristics of the current.
