Measuring water level with the float-operated angle encoder

Attention: Due to the current delivery situation, please request the product by email or via our contact form!

The OTT SE 200 angle encoder is a cost-effective alternative for measuring water levels in float shafts or gauge pipes. Its reliable float mechanism is activated by the smallest changes in water level and delivers precise measured values ​​that can be output in analog or digital form via standard interfaces. Existing writing levels can be easily and quickly upgraded to digital using the SE 200.

Application area: surface water, groundwater
Measuring technology: Float-operated angle encoder
Measurement parameter: water level
Product highlights: Easy system integration with standard signal 4 ... 20mA; Variable: available with float rope or pearl cord
Measuring range: ±30 m
Accuracy: SDI-12: ±0.003 % FS; 4 … 20 mA: ±0.1 % FS
Internal data logger: No
Interfaces: SDI-12 or 4 … 20 mA

Advantages:

  • Flexible use: in level pipes from 4" (optional with installation kit), in float shafts or as a cost-effective upgrade for mechanical recording levels
  • Precise measured values: The float wheel reacts to even the smallest changes in the water level. The current position of the float wheel is recorded electronically and saved as a measured value.
  • Optimized resolution: Assignment of the 4 ... 20 mA signal to the actually required partial measuring range is possible, thus even more precise measured values
  • Analog or digital data output: optionally 4 … 20 mA interface or 4 … 20 mA/SDI-12 combined
  • Optionally available with pearl cord: slip-free even with rapid water level changes
  • Suitable for connection to external data collectors, programmable logic controllers (PLCs) or displays


Area of ​​operation:

Water level measurement in groundwater and surface waters, e.g.:

  • gauge systems with float shaft
  • level pipes from 4"
  • Upgrade of level recorders for on-site digitization of measured values

Can also be used for level measurements.
