Water Current Velocity Measurements by a Magnetometer-Based Tilt
A novel instrument based on the tilt-drag principle is developed for measuring the instantaneous velocity of the water current. Instead to obtain the tilt by an accelerometer, a magnetometer is used. For a range of underwater velocities from 5 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$cm/5$</tex> to 50 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$cm/s$</tex>, the resolution of the instrument is 8.5 bits. The water velocity is obtained using edge computation by a microcontroller with a core based on an ARM CORTEX MO +. The error is less than a 5 % and the sensitivity 0.12 cm / <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$s$</tex> / LS B
