Guidense TDR200-SMART

Continuous guided level radar

with Smart bidirectional digital communication

The Guidense TDR200-SMART is a guided wave radar (GWR) for continuous level measurement in liquids and solids. The Guidense TDR200-SMART has no sensor outputs but a smart bidirectional digital communication output to the ProcessMonitor M844 monitoring and data logging solution. The combined instruments represent Processmonitors Smart Services.

With Smart Services we go further then just remote monitoring. It is now possible to gain full access to the measured sensor data for improving and optimizing your complete process. Even the echo curve which is the sensors core information can be visualized. Problems in the process conditions like foaming, swirling and level changes can be explained and corrected. which results in a reliable and stabilized process. The Guidense TDR200-SMART and the M844 Data Acquisition and Communication Module are the next level of Smart Level Measurement. You can easily read, modify, store and analyse all process parameters from anyplace, anywhere, anytime using a web browser.
Overview Guidense TDR200-SMART


  • Stand alone level monitoring and data logging solution independent from local infrastructures, using GSM /GPRS communications and solar panel, battery or AC/DC power options.
  • Easy and time saving remote configuration through Smart bidirectional digital communication, even when the M844 has a public, dynamic IP address.
  • Full control to easily read, modify, store and analyse all process parameters from anyplace, anywhere, anytime using a web browser.
  • 3 Probe types: single rod probe, wire rope probe and a coaxial probe.
  • Measuring range: 100 to 20.000mm.
  • Fastest reaction time with 0,5 sec in the market for smallest vessels / tanks.
  • No influences caused by tank / vessel internals.
  • Power supplied by the M844.
  • Accuracy of +/-3mm or 0.03% of measured distance.
  • Resistant to harsh environments with IP68/NEMA6P enclosure.
  • Smallest inactive areas in the market.
  • Applicable in nearly every type of process and storage tank application.

Power Supply

  • Power supplied by the M844.

Analog Outputs

  • No analog output.

Control Outputs

  • No switch output.

Smart bidirectional digital communication with related M844 which provides full access for configuration, measurement data and process analysis.

Extremely suitable Smart level measurement solution for off-grid and hard to reach locations.

Suitable in almost every liquid and solids - independent of changing process conditions, such as density, conductivity, temperature, pressure, vapour, turbulence, low dielectric constant or low reflectivity.
The Guidense TDR200-SMART has almost no installation restrictions - it can be mounted in small tanks, tall and narrow nozzles and it measures precisely even with difficult tank geometries or close to interfering structures.
