Instruments

Interocean S4 Current Meter

Supplied Name: S4 Current Meter

Supplied Description:

An S4 Current Meter (InterOcean Systems, Inc) was mounted on the MLML Particle Trap.

Instrument Type

Generic Name: Interocean S4 Current Meter

Acronym: S4 Current Meter

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0154/

Generic Description:

The InterOcean S4 current meter is a basic electromagnetic current meter with two pairs of internal electrodes and a flux-gate compass with an integral data logger. The S4 current meter is designed to directly measure with high precision the true magnitude and direction of current motion using two pairs of titanium electrodes located symmetrically on the equator of the sensor. An internal flux-gate compass provides heading information, used to reference current direction to magnetic North or, for fixed installations, the instrument may be operated in an X-Y orthogonal mode whereby the current vector can be referenced to a landform or structure.
