Water level
For water level and depth measurement, no application is the same in surface and groundwater. OTT Hydromet offers a variety of sensors with different measurement principles, tailored to fit the specific requirements of different hydrologic measurement sites, including bubbler, pressure sensor, radar, and shaft encoder technology. Multiple telemetry options are also available for remote data acquisition.
