The OTT SE 200 float-operated shaft encoder level sensor provides proven water level measurements in continuous, unattended monitoring in ground and surface water applications. A measured value is being calculated via internal processing and is available via the interfaces SDI-12 and 4 ... 20 mA.
The OTT PLS measures water level, depth to water, or pressure by means of an integrated controller and ceramic pressure-measuring cell. Design features such as multiple communication outputs (SDI-12 or 4 ... 20 mA), stainless steel housing, and a rugged cable make this sensor ideal for monitoring water level in a variety of applications.
The OTT CBS is a compact, accurate, and low power bubbler sensor for surface water level monitoring. The OTT CBS meets or exceeds USGS standards for accuracy, and will not drift over time. It features outputs for SDI-12 and 420 mA.
