摘要： A flow rate measurement unit includes: an inflow passage; an outflow passage; a screening passage including an inlet and outlet; an injector that injects a substance into the inflow passage; a first detector that irradiates the inlet with the light having the predetermined wavelength, and detects a first intensity; a second detector that irradiates the outlet with the light having the predetermined wavelength, and detects a second intensity; and a first controller that calculates a flow rate of the liquid by dividing a predetermined volume of the screening passage from the inlet to the outlet by a time difference obtained by subtracting a first time from a second time. The first time is taken from when the substance is injected until the first intensity reaches a peak, and the second time is taken from when the substance is injected until the second intensity reaches a peak.

摘要： This invention provides a multi-layer diaphragm which is for use in fluid devices and has excellent maintainability in addition to both operability and pressure resistance. This multi-layer diaphragm is provided with a first and second plate and with an elastic adhesive layer which binds together the first and second metal plates. The elastic adhesive layer has an elastic layer that is elastic in a direction which offsets the first and second metal plates from one another in the in-plane direction. The multi-layer diaphragm is provided with a metal mounting plate which, provided in a position allowing protrusion beyond the first and second metal plates in the outer edge direction, has a mounting unit for mounting to the fluid device.
