Abstract
All interface position determining apparatus includes a transmitter that transmits au acoustic wave from a plurality of positions in an accumulating direction in which impurities contained in a liquid accumulate, from an outside of a wall surrounding the liquid; a receiver that receives the acoustic wave transmitted from the transmitter at a plurality of positions; and a determining unit that determines a position of an interface between a liquid layer and a sludge layer in the accumulating direction based on a condition of the acoustic wave received by the receiver.

An interface position determining apparatus comprising:
- a transmitter that transmits an acoustic wave from a plurality of positions in an accumulating direction in which impurities contained in a liquid accumulate, from an outside of a wall surrounding the liquid;
- a receiver that receives the acoustic wave transmitted from the transmitter at a plurality of positions;
- and
- a determining unit that determines a position of an interface between a liquid layer and a sludge layer in the accumulating direction based on a condition of the acoustic wave received by the receiver,
- wherein the determining unit detects a transition layer where the liquid is mixed with impurities, and that is present between the liquid layer and the sludge layer, based on the condition of the acoustic wave received by the receiver, and divides the transition layer into a plurality of layers in the accumulating direction in which impurities accumulate, to define an interface between the layers as the position of the interface between the liquid layer and the sludge layer.
