OPTIFLEX 1100 Guided Radar TDR Level Meter

Brand: Krohne

OPTIFLEX 1100 C is a 2-wire TDR level meter for measuring distance, level, volume and mass of liquids and solids.

Its simple, compact design allows service technicians to quickly assemble the probe and attach it to a threaded connection.

It is an affordable solution for applications that do not require a high level of accuracy and is also an excellent alternative to traditional level controls such as RF Capacitance, conductive and DP transmitters.
Features
  • 2-wire loop-powered level meter for liquids and solids 
  • For general-purpose use (non-hazardous areas) 
  • Measuring range up to 20 meters / 65.6 feet (liquids) and 10 meters / 32.8 feet (solids) 
  • Easy menu navigation without opening the housing 
  • Probes and process connections are made of stainless steel 
  • For process temperatures up to 100° C (210° F) and pressures psig: 0 to 232 (kPa: 0 to 1,600, bar: 0 to 16)
