Claims

[Scope of utility model registration request]

The method includes: a throttle member provided with a throttle hole through which a measurement 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; and two plate-shaped holding members; The holding member is provided with a recess on one side, a through hole larger than the throttle hole, and a pressure-conducting hole that communicates between the recess and the through hole, and one end of each is connected to the recess. first and second fluid communication holes are provided which are open and each other end is open to an outer surface other than the one surface; the pressure guiding hole is provided with a stop valve for opening and closing the pressure guiding hole; A blocking plug is provided at the other end of each of the flow holes, the throttle member is configured such that the throttle hole and the through hole are coaxial, and the pressure receiving element of the differential pressure sensor is configured to face the recess. In this way, while being held between the two pressers and the members,
A differential pressure type flow rate measuring device, characterized in that the throttle member, the differential pressure sensor, and the holding member are integrally fixed by a fixing means.
