【発明の名称】運動媒体の特性を測定するための音響学的方法
Document Type and Number:
Japanese Patent JP2686302
Kind Code:
B2
Abstract:
PCT No. PCT/SE88/00587 Sec. 371 Date Jun. 30, 1989 Sec. 102(e) Date Jun. 30, 1989 PCT Filed Nov. 1, 1988 PCT Pub. No. WO89/04482 PCT Pub. Date May 18, 1989.The invention relates to a method for measuring parameters and/or properties in a mobile medium, e.g. a liquid or a gas. If acoustic energy is transmitted into a mobile medium, a flow is initiated in the medium. This flow is measured providing information on the properties of the medium. If the medium contains bodies which reflect acoustic and/or optical signals, ultrasound or laser-Doppler is used for measuring the velocity of the bodies. The Doppler-shifted signal provides information on the viscosity of the medium and on the bodies in the medium.
