SPOTTER PLATFORM

Current Meter

Add a rugged, single-point current meter to your Spotter Platform to measure subsurface current speed and direction in real time.

Sample precisely, rapidly, and at depth with motion-tolerant, tilt-compensated performance and energy-efficient solar-rechargeable power.

Deployment & Best Practices

Configuration Options
Ideal for moored coastal deployments with one Spotter or a network.Integrate up to two more devices (e.g. pressure/oxygen) per Smart Mooring (max 3 total).

Remote Configuration & Controls
Direct control via Spotter Dashboard, binary/ASCII commands, and Sofar remote support.

Mounting
Mount with sensor head (pressure port) pointing downward to prevent debris clogging.

Max Operational Conditions
Up to 100 cm/s current velocity.

Calibration
Recalibrate annually (~0.50% FS drift).

Maintenance
Rinse with fresh water after retrieval.
Clean the pressure port to remove debris.
