APEX Current Profiling Float

APEX_Electromagnetic_EM
APEX_Electromagnetic_EM

Only Teledyne Webb Research offers the APEX - EM, a spinning float that directly measures water motion through induced electromagnetic currents. The measurements determine the speed and direction of moving sea water in fine detail. This data is important for understanding major weather events.

Key Features:

Benefits:

  • Measures speed and direction of moving water to within a few centimeters per second accuracy
  • Aircraft deployable by parachute
  • Programmable for surface avoidance during extreme weather events
  • Deployment proven EM technology
