YEAR END PROMOTIONAL OFFER! Between now and December 31, 2018, every SonTek-SL 1500 or 3000 purchase will receive a free canal mount (view demo) which includes a 1.2m (4ft) length mounting frame section, slide assembly with adjustable angle mounting plate, and handle bar!* Mention promo code SLMOUNT during order. Additional mounting frame sections available for purchase.
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.

First time users can collect test data within minutes of receiving the SonTek-SL. Deployments require only a few minutes to configure the SL and start collecting data. This system provides the highest quality Doppler velocity data without requiring the user to become an expert on Doppler technology.
Water Velocity and Level: Water velocity, level, flow, and total volume-multiple parameters from one easy-to-use instrument. Acoustic Doppler profile of velocity data and acoustic water level offer the most accurate, reliable measurements.
SmartPulseHD®*: An intelligent algorithm that looks at water depth, profiling range, velocity, and turbulence, and then acoustically adapts to those conditions using pulse-coherent, broadband, and incoherent techniques. Best data possible under any condition. High-def cell sizes down to 4 cm.
Compact, Hydrodynamic Design: Incredibly lightweight and easy to transport and mount. Slim shape is easy to maintain, stays clean, increases available sample area, and fits into more places.
Water Velocity Profiling: Customizeable, flexible setup options to suit a variety of applications. 3G models offer 128-cells for high-resolution and detailed profiles.
Acoustic-Pressure "Duo" 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.
Versatile, Easy Mounting: Easy-access side mounting reduces concerns over personnel safety, lowers operational cost by avoiding divers and boats, avoids interruption in facility operations, and avoids interruption in data and water delivery to clients and stakeholders.
Wave Spectra Option: Integrated pressure sensor calculates and outputs wave-height and period, in real-time.

SonTek-SL 3G Firmware — v 3.100 — 06DEC2018
Find the latest version of SonTek-SL 3G Firmware here. Please contact firstname.lastname@example.org for technical help or questions.
Argonaut-SL/SW/XR Firmware — v 12.2 — 01MAR2016
Recent update corrects Modbus Output "Level" Parameter: The Modbus output of the "Level"parameter in Register 30051 & 30052 was corrected to not include the SystemElevation used in the "Stage" parameter and the flow calculations. It is now simply the water level above thevertical beam as intended. The changedoes not affect any other output formats (i.e. SDI-12) or internally recorded data.
Previous udpates include:
- Adds two new Channel Types (Culvert and Equation)
- Improved Total Volume calculations; allows accumulating volume even when collection is temporarily interrupted
- Option added to disable Total Volume Reset on the Flow Display
- Adds SDI-12 Auto Sampling, which allows instrument to continue data collection even when no data logger command is received
- Improved low-battery recovery; allows automatic data collection restart if a low-voltage battery recovers (e.g., when battery recharges itself via a solar panel)
- Adds an alternate method of interrupting data collection via a modem using plus (+) or equals (=) characters
- Scaling of analog output signals now based on setting of Total Volume units
If you wish to take advantage of the new features in this version, follow the instructions below based on the version of firmware currently in your system.
