PROBLEM TO BE SOLVED: To securely fix both end parts of a measuring pipe and restrain a liquid leak from both ends of the measuring pipe.SOLUTION: A thermal type flowmeter is equipped with an inflow side body 16 into which an inflow port 11a of a measuring pipe 11 is inserted, an outflow side body 17 into which an outflow port 11b of the measuring pipe 11 is inserted, an inflow side nut 15a in which a female screw 15g to be linked with a male screw 16b formed on the inflow side body 16 is formed, an outflow side nut 15b in which a female screw 15h to be linked with a male screw 17b formed on the outflow side body 17 is formed, a resin-made inflow side ferrule 18 deformed by linking of the inflow side nut 15a with the inflow side body 16 to form a seal area, and a resin-made outflow side ferrule 19 deformed by linking of the outflow side nut 15b with the outflow side body 17 to form a seal area.SELECTED DRAWING: Figure 3 |
