They have a newly installed moisture analyser and would like some help with calibration.

The questions to the study group are as follows…

  1. Is the analyser capable of analysing moisture?
  2. If so, what is the best calibration?

Data

We have 1 sec interval data from the analyser for a few months.

  • Attenuation
  • Phase Shift 1
  • Phase Shift 2
  • Depth
  • Tonnage

We have corresponding moisture data as measured in the lab approx. 3-4 sample per day

Background Reading

 

Confidentiality

The analyser vendor has given us full access to the data but it should not be shared outside the study group. The conclusions can be shared.
