Abstract

PURPOSE: To detect the boundary of two types of liquids quickly with high accuracy and to prevent the scaleover of the boundary, by using the optical detection set.
CONSTITUTION: Liquids not solble each other are poured into the manometer 18 for the vessels 16, 17 linked at the bottom with the manometer 18 substantially held horizontal so that the boundary is appeared, and the displacement of the boundary of the two liquids caused by the pressure difference exerted on the respective liquid surface of the vessels 16 and 17 is detected at the manometer. In this case, the detection section is provided with the transmitter 21 and the photo detectors 19, 20, 20', and the detection of the boundary is made by using the transmitted light amount of liquids or the refractive index.
