Features:

  • A wide range of applications, direct installation in storage silos, hoppers, vessels, sumps, etc.
  • Variants with fully coated electrodes for aggressive or electrically conductive media.
  • Measured data in real-time on the display (OLED or LCD available).
  • Analog output 4 – 20 mA with digital two-way communication HART®.
  • Compared with reflective level meters, CLM-70 measures along all the electrodes in full range (no dead zones).
  • Contrary to radar level meters, also media with extremely low dielectric constants (εr) can be measured.
  • Possible copying the configuration between level meters using the display module.
