A stereophotogrammetric technique is described which was used to measure amplitudes and wavelengths for wave patterns generated at the interface between two liquid layers flowing co‐currently in a closed rectangular conduit. In the preliminary experiments differences in the interfacial elevation due to the presence of Waves of amplitude as low as 0.2 mm. and wavelength of 75 mm. could be detected using this technique. Stereophotogrammetry having the advantage that no probes of any kind interfere with the flowing liquids may well become another useful tool in chemical engineering research.
