Abstract

PURPOSE:To optically measure the density of sludge, etc. easily and exactly, by cleaning the transparent cylindrical body of the measuring head part by use of the piston seal. CONSTITUTION:The density of sludge flowing into the transparent cylindrical body of the density measuring head part 30 is measured through the projector and the photodetector 3, 5. This cylindrical body 2 is cleaned by the seal member 14a of the piston seal 14, and the density of sludge, etc. can be measured easily and exactly by only inserting the head part 30. In this regard, the head 30 can be lifted and lowered along the inwall of the guide part, as well.
