Abstract

The invention relates to a transmitter for consistency measuring of pulp suspensions at first hand, comprising a measuring body (1), shaped such as a blade, suspended in a vibration-producing apparatus. The measuring body (1) shaped such as blade (I′) shows wave-shaped side surfaces (9, 10) in its transverse direction and is vibratable in a frequency of oscillation between 20-80 Hz and with a predetermined amplitude of +/−2-8 mm, that provides a combination of both shearing force measurement and a measurement of the resistance of conveyance of liquid through a fiber netting.
