American SonTek SL500 real-time online acoustic Doppler flow meter

Measuring flow velocity and water level in natural rivers and open channels requires a simple and effective instrument. SonTek-SL (abbreviation: SL or side-view ADCP), as an automatic online flow monitoring instrument, has been recognized and widely used in the industry. The two latest novel styles (3G) developed and developed adopt SonTek’s new technology – smart pulse function (SmartPulseHD). With application software, optional mounting brackets and various compatible integration methods, they can meet more user needs. requirements and applications. Specially designed, the instrument can be installed on bridge piers, channel walls or river banks. Smooth and flat shape makes on-site installation easier. Three models of different specifications are available, which can be used in small channels that can be jumped with one foot, or in large rivers like the Amazon River. The ultra-narrow acoustic beam and side-lobe suppression function avoid interference from the water surface and river bottom, allowing the sound waves to be emitted farther, thereby obtaining a larger horizontal measurement range.

American SonTek SL500 real-time online acoustic Doppler current meter application:
A reliable, classic online current meter installed on a dock or river bank for quick maintenance without the need for divers or boats. Compared with similar products from SonTek, it is lighter and easier to install. The horizontal measurement range is up to 120 meters. Especially suitable for:
·Suitable for long-distance rivers and ports
· Large rivers, estuaries, and water supply channels
· Installed on bridge piers and docksides to measure tides and current speeds for port security, ship navigation and weather forecasting
· Offshore platforms
SonTek-SL1500 (3G): widely used in medium width rivers
Flat and slim design, with intelligent pulse function, SL1500 (3G) becomes a powerful flow measurement system. Collect high-quality horizontal profile data, flow measurement range: 0.2-20 meters. With the side-view installation method, high-resolution and high-quality data can still be obtained even if water flow conditions change, thanks to the intelligent pulse function. Especially suitable for:
· Rivers, streams, water supply channels, irrigation channels, drainage channels
·Exhibits unparalleled performance even under very small flow rates (even flow interruption) or counter-flow conditions
· Meet the needs of simple installation and maintenance and uninterrupted projects in hydropower, heavy rain, and municipal construction
SonTek-SL3000 (3G): a smaller instrument
The smallest and lightest side-viewing Doppler flowmeter of its kind. SL3000 (3G) can use smaller sampling units, and the application channel can even be as small as 0.5 meters. High-resolution section unit, the smallest unit is only 4 cm. No matter how narrow the channel is, high-precision data can still be measured near the shore, the channel wall, or the edge of the hydraulic structure. Especially suitable for:
· Rivers, streams, water supply channels, irrigation channels, drainage channels
·Exhibits unparalleled performance even under very small flow rates (even flow interruption) or counter-flow conditions
· Meet the needs of simple installation and maintenance and uninterrupted projects in hydropower, heavy rain, and municipal construction
