SonTek-SL 3G with SmartPulseHD®

TECH NOTE: SonTek-SL 3G with SmartPulseHD®

The new SonTek-SL (3G) features SonTek's exclusive SmartPulseHD®* feature for dynamic selection and optimization of the acoustic pulsing scheme. The feature was first introduced with the RiverSurveyor ADCP for instantaneous discharge measurements on moving platforms. Later, the feature was incorporated in the fixed-mounted SonTek-IQ. SmartPulseHD's unique algorithms provide the user "intelligent" data and this technical note describes the feature and its use in SonTek-SL 3G instruments. *Patent pending.
