Abstract

See full text

Fiber content measuring instruments having radiation detectors are used to indicate the average radius and/or the average length of particles in a flowing medium. In order to determine the average radius, a signal based on the alternating current voltage portion of the signal from a radiation detector having a high resolution is divided by a signal based on the direct current voltage portion and the signal from a radiation detector having the same or another resolution. In order to determine the average length a signal based on the alternating current voltage portion of the signal from the radiation detector having a low resolution is divided by a signal based on the alternating current voltage portion of the signal from the radiation detector having a high resolution.
