Monitor Technologies’ Flexar® guided wave radar sensor is a continuous level measurement system using TDR (time domain reflectometry) principles. 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. The sensor:
- Can be used in dusty conditions.
- Can be interfaced to existing PLC or DCS with the analog 4-20mA output version.
- Has no moving parts.
- Does not require field calibration.
- Can be linked to the optional SiloTrack® software to automate level monitoring and report generation, to send email notifications to suppliers or corporate locations and to allow remote viewing of material level inventory.
