Claims

[Scope of utility model registration request]

a pressure detection unit main body, and provided at different positions within the main body,
a pair of first and second flexible membranes that are integrally displaceable with respect to each other; a pressure chamber defined outside the first flexible membrane within the main body; 1. A flexible membrane chamber defined between the first and second flexible membranes, a pressure path provided in the main body and guiding the pressure of the fluid passing through the flow meter to the pressure impulse chamber, and the pressure impulse The first and second flexible membranes are connected to the first and second flexible membranes, which are displaced in response to the pressure of the chamber, and further include a shaft body which is displaceable in an amount corresponding to the pressure of the fluid; A pressure detection unit that is provided in communication with a membrane chamber and that detects a pressure change when the fluid leaks into the flexible membrane chamber through the first flexible membrane. Detection unit.
