The OLC series consists of a screw-in prism unit and an optical level detection device. The prism is installed in the compressor or the vessel and is not included with the OLC. The level detection device can be replaced without opening to the compressor or the vessel. Detection of the level is via infrared light. There is a built-in monitoring system for correct installation.
