Krohne Non-Contact Radar Level Meter, OPTIWAVE 7300 C

OPTIWAVE 7300 C Non-Contact Radar Level Meter

Brand: Krohne
Add Product to My Catalog

This device is a non-contact Radar (FMCW) Level Meter for distance, level, volume and mass measurement of liquids, pastes and slurries. 

It gives a stabler measurement than pulse radar and is well suited to agitated 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 
  • Optionally equipped with a 4-button touch screen display and an easy-to-use setup wizard 
  • Reliable measurement in difficult process conditions 
  • Operates up to a process connection temperature of 200° C (390° F) and psig: 1,450 (kPa: 10,000, bar: 100) for standard applications, and up to 570° C (1058° F) for molten salt applications 
  • Measuring range up to 260 feet (80 meters) 
  • Horn and drop antenna versions can be extended to suit any nozzle length 
  • Drop antenna for corrosive liquids (with optional PTFE/PP flange plate) or where product build-up is likely to occur 
  • Sealed drop antenna extension option for pressurized tanks 
  • Hygienic antenna for processes where stringent hygiene standards must be obeyed 
  • PACTware and DTMs included as standard 
  • Optional second current output 
  • Directly-accessible graphic touchscreen/wizard (option) 
  • Converter rotates 360° 
  • Triple barrier gas-tight protection available for working with dangerous gases (using pre-stressed fused glass) 
  • Fast motion software that can measure 5 times per second for wave height measurement
