Claims

[Claims for Utility Model Registration] A throttle member provided with a throttle hole through which a measuring fluid flows to generate a differential pressure; a differential pressure sensor formed in a columnar shape and provided with pressure receiving elements at both ends; a holding member; a second holding member formed into a plate shape and consisting of a cover portion and a main body portion;
each of the holding members has a recess on one side, a through hole larger than the throttle hole, and a pressure conducting hole that communicates the recess with the through hole; and a first ↓ and a second screw-type stop valve that opens and closes the pressure guiding hole in the middle of the pressure guiding hole, each of which has one end opening into the recess and each other end opening onto an outer surface other than the one surface. A flow hole is provided, a blocking plug is provided at the other end of each of the first and second body flow holes, the throttle member is arranged such that the throttle hole and the through hole are coaxial, and the The differential pressure sensor is held between the holding members with the pressure receiving element facing the recess, and the aperture member, the differential pressure sensor, and the holding members are integrally fixed by a fixing means. A differential pressure type flow rate measuring device formed by forming the cover portion. The above when the foreboard second holding member is divided into a first part including the recess and a second part not including the recess so as to cross the pressure guiding hole between the recess and the stop valve. and the main body portion is formed to be the first portion, and the main body portion is formed to be the second portion.
A differential pressure type flow rate measuring device characterized in that it is formed into two parts.
