Abstract
PURPOSE:To suppress the influence of a pressure change in a main tank which may be generated due to the vibration of a vehicle by arranging a measuring room connected to a correcting tank in the main tank storing an object to be measured and finding out the volume of the object stored in the measuring room. CONSTITUTION:When a speaker 3 is driven, a pressure variation in the measuring room 14 is detected by a microphone 4. Oh the other hand, a pressure variation in the correction tank 2 is detected by a microphone 5. An output from the microphone 4 is inputted to a BPF 8a and an angular frequency signal component is extracted. The component is outputted by an amplitude detector 9a as an amplitude value corresponding to the component. On the other hand, an output from the microphone 5 is inputted to a BPF 8b and an angular frequency signal component is extracted. The component is outputted by an amplitude detector 9b as an amplitude value corresponding to the component. These output signals are supplied to a divider 10, the output of the detector 9b is divided by the output of the detector 9a to calculate the volume of a cavity part in the measuring room 14 and then the calculated value is subtracted from the whole volume of the measuring room 14 by a subtractor to output the subtracted result as the volume of the object to be measured.
