摘要：
When a suspension is exposed to a field of ultrasound, a voltage can be tapped from two electrodes whose distance apart is an odd multiple of half ultrasonic wavelengths, and this voltage can be used as a controlling factor for the addition of, preferably, retention and flocculating agents to the suspension. The process is particularly suitable for fibre suspensions for the purpose of monitoring the starting process in paper machines and for rapid operating control.
