Side-Looking Doppler Current Meter - SL Series

Horizontal Tabs


The SL is designed specifically for side mounting on bridges, canal walls or riverbanks; the SL’s low-profile housing makes installation easy. With three models to choose from, the SL can be used in channels as small as you can jump across to rivers as wide as the Severn Estuary. Ultra narrow beam widths combined with unmatched side lobe suppression provide the acoustic directivity necessary for achieving maximum horizontal range free of interference from surface or bottom boundaries. SonTek's user interface allows easy operation with minimal training and experience. Deployments require only a few minutes to configure the SL and start collecting data. The SL provides the highest quality Doppler velocity data without requiring the user to become an expert on Doppler technology.
