SonTek-SL Series

Inspired by the need for a SIMPLE way to measure water velocity and level in open channels, the SonTek-SL (affectionately known as the Side-Looker or SL) has earned worldwide acceptance as a long-term monitoring solution. Now, with two new (3G) models turbo-charged by our proprietary SmartPulseHD, the SonTek-SL features accessories, mounting options, software, and a variety of integration formats to ensure it fits your application.
Designed specifically for side mounting on bridges, canal walls, or riverbanks, the SL's SLEEK, 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 Amazon. Ultra narrow beam widths combined with unmatched side lobe suppression provide the SUPERIOR acoustic directivity necessary for achieving maximum horizontal range free of interference from surface or bottom boundaries.

Three models are available:
1) SonTek-SL500: Long-Range Option for Rivers, Ports and Harbors
2) SonTek-SL1500 (3G): Mid-Range Option with Wide Array of Use
3) SonTek-SL3000 (3G): Great Things Come in Small Packages

Special points of interest:
- Vertical acoustic beam plus pressure sensor for water level (3G models only). Not only redundant sources of water level, the acoustic vertical beam and pressure sensor continually self-check, and pressure data are auto-corrected to keep atmospheric offset negligible.
- Multicell velocity profiling
- Independent velocity measurement cell. This cell can be different in size from the multicells and located anywhere within the instrument's sampling range. This cell is used for flow calculations or other specialized functions
- Flow computation and output, including total volume
- FlowPack Velocity-Index Discharge Rating software package

Optional accessories:
- Canal Mount for installation in open channels.
- Easy-to-use Argonaut Flow Display for viewing SL500 data and system status
- Easy-to-use SonTek Flow Display for viewing SL (3G) data and system status
- SPF1500 protects against fluctuations in power and communications over long cable lengths
- External battery pack for autonomous operation (500WH)
