Abstract
Device for measuring the length and number of fibers in an aqueous suspension has a sensor with an upper and lower electrode with an insulating part between the electrodes, a rectifying channel having an inlet and outlet part, the first in close contact with the upper electrode, the second in close contact with the lower electrode, with mutually aligned openings of the sensor and the rectifying means. This arrangement can be applied for such suspensions of fibers or other particles, the electric conductivity of which is different from the conductivity of their carrying medium.
