摘要： Provided is a flow meter including a cylindrical measurement tube having an internal flow passage, and a sensor substrate including a heating resistance wire and a temperature detecting resistance wire formed on a detection surface thereof along an axis. An outer circumferential surface of the measurement tube is provided with a flat surface arranged as opposed to the detection surface, and a pair of recesses arranged so as to sandwich the internal flow passage at a position where the heating resistance element is arranged. The flat surface and the detection surface are bonded together to form a bonding area A having a width in a direction orthogonal to the axis. A width of a first portion on the axis where the pair of recesses is arranged is narrower than a width of a second portion on the axis where the pair of recesses is not arranged.

摘要： Provided is a pressure detection device, wherein a pressure detection unit includes: a pressure detecting diaphragm; a second connection portion; and four strain resistance portions. One of either a first connection portion or the second connection portion is formed of a magnet, and the other of either the first connection portion or the second connection portion is formed of a magnet or a magnetic body. The first connection portion and the second connection portion are arranged such that the first connection portion and the second connection portion are attracted by a magnetic force in a state where a flow passage unit is mounted on the pressure detection unit. The four strain resistance portions are attached to a region of a second surface of a pressure detecting diaphragm other than a center portion.

摘要： Provided is a pressure detection device comprising a pressure detection unit configured to detect pressure transmitted to a pressure detecting surface; a flow passage unit including a flow passage configured to allow fluid to flow along a flow direction from an inflow port to an outflow port, and a pressure transmitting surface configured to transmit pressure of fluid flowing through the flow passage to the pressure detecting surface; and a mounting mechanism by which the flow passage unit is removably mounted on the pressure detection unit. The pressure detecting surface includes a sliding layer having a sliding property for when the pressure detecting surface comes in contact with the pressure transmitting surface.

摘要： Provided is a pressure detection device including: a pressure sensor including a pressure detection surface for detecting a pressure of a fluid; and a flow channel unit having a flow channel formed therein to guide the fluid to the pressure detection surface. The flow channel unit includes a flow channel body having the flow channel 21a formed therein, and an earth ring disposed in contact with the pressure sensor. The earth ring is formed of a conductive fluororesin material including a fluororesin material and a conductive material in which the fluororesin material is dispersed, and is maintained at a ground potential.
