Muir Matheson deploy the S4A current meter which coupled with PACE software provides accurate and reliable instantaneous and historical sea current data.  The S4A Instrument family is a continuing evolution in a series of proven multi-purpose hydrographic data acquisition products that are continuously upgraded using the latest devices and techniques in microprocessor based instrumentation. The versatile S4A instrument configurations are designed to provide direct measurements of Current Speed and Direction, Directional Wave, Tide, CTD, Salinity, Density, Sound Velocity, Turbidity, Chlorophyll and other parameters with high precision. The S4A is a truly unique instrument for water current sensing, designed to directly measure the true magnitude and direction of current motion in any water environment 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.
