Electromagnetic Velocity Meter


Description: Electromagnetic current meters use Faraday's Law of electromagnetic induction to determine the velocity of water. The meter is attached to a wading rod, where it is lowered and raised to different water level elevations to measure velocity within that water column. This is performed in increments at a cross section of the channel to produce a discharge calculation. The Electromagnetic current meter is accompanied with a handheld device that displays the individual measurements.
