摘要：
In a method of and an apparatus for measuring a liquid content of a mixed phase fluid in a container, an oscillating voltage is applied to the fluid and a current with conductive and capacitive components derived, the conductive component being cancelled out. The capacitive component is phase shifted (34) into phase with the oscillating input voltage. A feedback loop (32, 23, ∑) attenuates the conductive component, avoiding amplifier saturation.
