Abstract

　被測定流体が流れるメイン流路７と、メイン流路７から被測定流体を分流させる分流部９と、分流部９から分流された被測定流体がメイン流路７へ流通する分流部１０と、分流部９，１０間の主流路に設けた被測定流体の流れを絞る絞り部９ａ，１０ａとを有するボディ部２と、分流部９，１０に連通して被測定流体を流通させる流路を設けた分流路構造部１１と、分流路構造部１１に設けられた流路に面して配置されたセンサ１５を有し、当該センサ１５が検出した分流部９，１０から導入された被測定流体の検出結果に基づいて被測定流体を計測する流体計測部３とを備え、分流路構造部１１及び流体計測部３が、ボディ部２に対して着脱自在である。
