Our products

Electromagnetic speed logs

Electromagnetic speed logs

Electromagnetic logs, or EM logs, calculate both speed and distance covered during navigation. The ship's speed through the water (STW) is measured through electromagnetic sensors installed in the hull and in direct contact with the water.



Repeaters display on a single unit all the data collected by the various on-board equipment for the smooth running of the ships (navigation, weather, armament, etc.).



Flowmeters are used to measure liquid flows. Depending on the application, BEN Marine flowmeters are available in two versions: electromagnetic or ultrasonic.

 Compass and diver compass

Compass and diver compass

Magnetic compasses for surface vessels and divers capable of withstanding severe conditions.
