Electromagnetic log measures ship’s speed and indicates distance traveled.
The electromagnetic log measures speed through water (STW) from the flow of water at the bottom of the ship and calculates the total distance of navigation.
We have two types of sensor : single-axis (fore-to-aft) and dual-axis (fore-to-aft and starboard-to-port).
We have variations of sea valve for each ship’s bottom conditions.
