OPTIWAVE 6300 C Non-Contact Radar Level Meter

Brand: Krohne
Request Information
Favorite

This device is a non-contact Radar (FMCW) Level Meter for distance, level, volume, mass and reflectivity measurement of powders, granulates and other solids. 

It gives a stabler measurement than pulse radar and is well suited to dusty process conditions. 

The device can operate at very low and very high process temperatures as long as the process connection temperature limits are observed.
Features
  • ±0.12" (±3 mm) standard accuracy 
  • PP or PTFE drop antenna: Its shape prevents product build-up in dusty applications 
  • Operates up to a flange temperature of 200° C (390° F) and psig: 580 (kPa: 4,000, bar: 40) 
  • Measuring range up to 260 feet (80 meters) 
  • Antenna can be extended to suit any nozzle length 
  • PACT ware and DTMs included as standard 
  • Optional second current output 
  • Directly-accessible graphic touchscreen/wizard (option) 
  • An installation wizard specifically for solids that permits the instrument to measure uneven surfaces accurately
