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.
