ABSTRACT:
A method and apparatus are disclosed for obtaining a measurement indicative of the aspect ratio of non-spherical particles in suspension. Conductivity of the suspension is measured for two different orientations of the particles between measuring points and the difference between the conductivities measured is used as an indication of the particle aspect ratio. The particle orientation will be aligned in one measurement and in the other may be aligned and transverse to the first orientation direction or random. Alternatively, there may be a single aligned orientation but transversely directed conductivity measurements.
