Claims

[Scope of utility model registration request]

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; A pressure guiding port provided on one side and the throttle hole; two plate-shaped holding members provided with a larger-sized through-hole and further provided with a pressure-conducting hole that communicates the pressure-conducting port with the through-hole; The differential pressure sensor is held between the holding members so that the pressure in the through hole is coaxial with the through hole, and the pressure in the through hole is guided to the pressure receiving element of the differential pressure sensor via the pressure guiding port. The differential pressure type flow rate measuring device is formed by integrally fixing the throttle member, the differential pressure sensor, and the holding member with a fixing means, in which one of the holding members is fixed to the measuring fluid. A pressure sensor is embedded in one of the holding members and the throttle member to detect the temperature of the fluid to be measured, and a temperature sensor is embedded in one of the holding members and the throttle member to detect the temperature of the fluid to be measured. A differential pressure type flow rate measuring device comprising a pressure sensor, and a computing unit that performs computation using each output signal of the pressure sensor and the temperature sensor and outputs a signal corresponding to the flow rate of the measured fluid.
