Abstract

1,200,072. Liquid level indicators. ODIN CLORIUS A/S. Aug.2, 1967, No.35465/67. Heading G1H. In a liquid level indicator in which the surface of a liquid in a transparent container is read on a vertical scale a coloured surface is provided in the container above or below the liquid surface and the colour is viewed in the plane of the liquid surface by reflection at the meniscus of the surface.
