We have developed a method to extract fibre length distributions from acoustic data recorded on pulp streaming from a TMP refiner. The method is based on the use of a Continuous Wavelet Transform, CWT. Measurements were performed using an accelerometer on the refiner blow-line during a full-scale trial with a double disc refiner. During trials conditions were varied over a wide range. The agreement is good between results from our method, CWT-FLE and from FiberMaster.
