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.
