Dynamic characteristics of a liquid surface (160) are measured by sending acoustic signals (140) to or more target areas (162a-162c) on the liquid surface and receiving said acoustic signals (150a-150c) after reflection from the target area. The detected signals are processed to measure phase shift between the sent and received acoustic signals, the measured phase shift varying over time. The varying phase shift is used to indicate fluctuations over time in the local height of the liquid surface in the target area. The liquid may be water, effluent etc. flowing in a channel or conduit. With suitable calibration, the measured height fluctuations can be used to infer flow characteristics such as surface roughness, wave height, flow depth, flow velocity, volumetric flow rate, shear stress, sediment transport. Using an array of receivers and target areas, additional spatial and temporal characteristics of the surface and the flow can be measured.

47 METHOD AND DEVICE FOR SENSING OF OBSTACLES FOR AN AUTONOMOUS DEVICE EP95914657.0 1995-03-28 EP0753160A1 1997-01-15 EDLUND, Leif
The present invention provides a method and a system for proximate field orientation of an autonomous device and utilizes a transmitted wave having a first frequency of slow propagation, whereby reflections from obstacles within a proximate area are detected. According to the present invention receiving means are arranged in a slanted plane or preferably along a curved base-line to, in a simple way, obtain a three-dimensional direction to an obstacle reflecting the frequency of slow propagation. Additionally is arranged above at least one receiving means an absorber or a screen or a combination thereof, whereby that acts as an 'eyebrow' attenuating undesired reflections which at the receiving means come from overhead. Additionally at least one of the receiving means along the generally curved base-line is arranged differently in height in relation to the remaining receivers and preferably the most outer receiver means on each side in the line of receivers along the generally curved base-line are arranged differently in height in relation to the remaining receiving means for an improvement of the three-dimensional resolution.
