The KROHNE OPTIWAVE 6500 C Level Meter is a 2-wire 80 GHz radar (FMCW) level transmitter for demanding applications with powders in very dusty atmospheres. With its small beam angle, this radar is particularly suited for continuous, non-contact level measurement in high and narrow silos, hoppers or buffer storage containers up to 100m / 328ft Due to the high signal dynamics of the FMCW radar, the level transmitter is ideal for low-reflective media, dust, uneven surfaces or tanks with obstacles. As it features a flush-mounted PEEK Lens antenna, there is no intrusion of the antenna into the tank.

The OPTIWAVE 6500 provides accurate and reliable readings in process conditions with temperatures up to +150°C / 302°F and pressures up to 40 barg / 580 psig. It offers flange or thread connections as well as an optional 112mm / 4.4in antenna extension for the DN40 / 1.5in antenna. Approvals for use in hazardous areas are also available. The level transmitter comes with HART 7 communication.

Applications for the 6500 C include:

  • General level measurement
  • Minerals and Mining Industry
  • Chemical Industry
  • Food and Beverage Industry
  • Power Industry, Iron, Steel and Metal Industry
  • Pulp and Paper Industry
