The Fixed Profiling System delivers reliable, fully automated data collection for water column insights.
Mountable on a dam, pier, piling, or other stationary location, the Fixed Vertical Profiler offers user-programmable sample intervals and wireless transmission options. The profiler is compatible with all YSI EXO Sondes equipped with depth, and comes with Profile Wizard software for easy setup, configuration, and deployment.
When paired with a fully-loaded EXO Sonde, the fixed profiler can be programmed to move up and down the water column at regular intervals, collecting high-resolution data on water conditions across various parameters. Data can be transmitted via telemetry or a direct connection, such as Ethernet, for visibility into changing water conditions. With timely insights, operators can respond quickly and optimize operations.
Some of the notable features are:
- NEMA4 enclosure protects system electronics
- Compatible with all EXO Sondes equipped with depth
- User-selectable sampling intervals
- Profile Wizard Software for simple program configuration
- Wireless or direct-connect data transmission options
Applications include:
- Drinking water reservoirs monitoring water quality: salinity, turbidity, temperature, chlorophyll, DO, pH, and PAR (photosynthetically active radiation)
- Homeland security applications
- Research on upwelling events
- Hydropower thermal phenomena and temperature studies
- General monitoring of lakes, rivers, estuaries, and bays
- Industrial drinking water holding tanks
If you're interested in additional profiling systems, we also offer pontoon profilers.
Available Options:
- SCADA Interface - Allows for data collection from a YSI Vertical Profiler via direct connection or telemetry to a customer's PLC
