CL series
CL series
Electric and distortion type level meter that can make completely non-contact measurements.

The meter is constructed so that a precise electric distortion sensor is part of the metal support. This sensor is inserted into a support of the bottom of the tank so that the electric distortion sensor can measure the volume of material in the tank.

  • For liquid
  • For powder

These meters can measure various substances from liquid to powder, and granulated materials. The special cylindrical sensor and unique installation method make it highly reliable.


Features, keys

  1. The sensor is a completely non-contact type so it is not affected by the status of the tank.
  2. The meter can measure almost any material.
  3. The special cylindrical sensor and unique installation method make it highly reliable.
  4. High reliable and stable against temperature change.
  5. The sensor can be installed easily in a conventional tank.

Usages, use examples

  • When a level meter cannot be installed in a tank.
  • Want to measure levels with completely non-contact
