Monitor Technologies’ Flexar guided wave radar sensor is a continuous 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) and 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 numerous liquid applications, as well as virtually all powder and bulk solids applications, including dusty conditions. The Flexar sensor can be interfaced to an existing PLC or DCS with the analog 4-20mA output version. The Flexar sensor also can be linked to the optional SiloTrack software to automate level monitoring and report generation, send e-mail notifications to suppliers or corporate locations and allow remote viewing of material level inventory.
Other benefits of Flexar include no moving parts for less wear and tear, a universal power supply for high or low voltage choices, and an optional split architecture configuration for high temperatures or high vibration.
