Claims (3)
- 製鉄工場における排水管内を流れる排水の水質計測方法であって、センサー本体の上部取付部をボルトによりブラケット及び弾性材を介して排水管上部の基台にルーズに固定するとともに、先端部を排水管内の排水流中に挿入して、センサー本体が排水流に対して揺動自在となるように排水管に取り付け、前記センサー本体の下流側に生じるカルマン渦によりセンサー本体の前後間に分圧差を発生させ、これによりセンサー本体を排水流中で自然揺動して自己洗浄させながら水質の計測を行うことを特徴とする水質計測方法。
- 製鉄工場における排水管内を流れる排水の水質計測装置であって、センサー本体の上部取付部をボルトによりブラケット及び弾性材を介して排水管上部の基台にルーズに固定するとともに、先端部を排水管内の排水流中に挿入して、センサー本体が排水流に対して揺動自在となるように排水管に取り付けられた構造とし、前記センサー本体に下流側に生じるカルマン渦によりセンサー本体の前後間に分圧差を発生させ、これにより排水流中で自然揺動する自己洗浄機能をもたせたことを特徴とする水質計測装置。
- センサー本体の上部取付部と排水管外壁との間に弾性材が介在されている請求項2に記載の水質計測装置。
