Signature500

Mean currents and turbulence, plus wave height, direction and ice tracking

The Signature500 ADCP is designed for flexibility. It measures current profiles at up to 8 Hz sampling frequency. It can also measure direct vertical velocity profiles, wave height and direction, and ice thickness and drift. The center beam also functions as a biological echosounder, enabling high-resolution measurements of biomass in the water column. All these features can be combined using Nortek’s patented concurrent mode technology.
