Abstract
Optical transmittances of a combination of a liquid to be detected and a container wall are measured in order to select two optical pass-bands, one of which is relatively high transmittance level while the other of which is relatively low transmittance. The light transmission quantities of the container at the selected two pass-bands are measured by one or more detecting elements. The light transmission quantities are converted into two electric signals, one of which is divided by the other in a signal process circuit.
