ABSTRACT:
There is disclosed an apparatus for use in an aerated bath comprising a sensor to sense mass concentration within a liquid, a dedubbler for forcing bubbles from the portion of the liquid to be sensed by the sensor, away from the sensor, and a flow limiter to limit liquid flow past the sensor to no more than that rate at which the debubbler can force bubbles away from the portion to be sensed. The debubbler removes bubbles and the sensor senses mass concentration without removal of liquid from the confines of the bath and before the liquid portion is reaerated by the bath. A process of sensing in the absence of bubbles is also disclosed.
