113825.tifGuided Wave Radar Level Sensor
The Flexar guided wave radar sensor is a real-time, continuous bin level measurement system using TDR (time domain reflectometry) principles where radar pulses are focused down to the material surface by the unit’s wave guide (a heavy-duty cable) where the time-of-flight of the pulse reflection back to the instrument electronics is directly related to the empty distance in the vessel and the material level. Guided wave radar technology has proven successful for most powder and bulk solids applications, including dusty conditions. It is also suitable for a multitude of liquid applications. The real-time measurement ability of the Flexar works well for dynamic storage situations including concrete batch plants, grain elevators during peaks times, and in balancing material levels in surge bins that supply pellets used to fuel furnace or boiler fires.
