The ISM-2001 Current Meter is a robust inductive sensor that is suitable for both long-term monitoring and profiling. The two-component current meter can be used in adverse conditions from the seafloor to just below sea surface. The device also measures in water with gas bubbles or turbid water.
The specially designed sensor generates a changing magnetic field in its surrounding. Free charge carriers pass through this magnetic field near the sensor and are separated by the Lorentz force building up an electric field that is linear to the flow velocity. Two pairs of electrodes measure the voltage, which is converted into flow velocities in two different directions. A two-axis magnetometer is available as a compass for precise output of the current direction.
