The physical quantity measurement device for measuring the physical quantity of the fluid has a measurement flow passage through which the fluid flows; a detection element for detecting the physical quantity of the fluid; a plate-shape physical quantity detector that detects the physical quantity of the fluid by the detection element in the measurement flow passage; a protection body that protects the physical quantity detector; a body recess arranged on the outer surface of the protection body at a position separated from the physical quantity detector in the orthogonal direction, which is orthogonal to a thickness direction of the physical quantity detector.

A physical quantity measurement device includes a physical quantity detector that detects a physical quantity of a fluid in a measurement flow path, a physical quantity processor that receives a detection result of the physical quantity detector, and a support plate part that supports the physical quantity detector and the physical quantity processor. The support plate part includes a detector support portion to which the physical quantity detector is attached, and a processor support portion that is located at a position spaced apart from the detector support portion and to which the physical quantity processor is attached. Between the detector support portion and the processor support portion, a heat transfer regulation portion is provided to regulate heat transfer from the processor support portion to the detector support portion.

In some examples, a system includes an airflow sensor disposed at least partially within an air intake system for an engine. The airflow sensor may be configured to measure a flow rate of air flowing past the airflow sensor in the air intake system, and includes a sensor element and a heater associated with the sensor element. A heater control circuit may control the heater to control a temperature of the sensor element. Further, a processor may be configured by executable instructions to cause the heater control circuit to, in a first operation mode, maintain the sensor element at a higher temperature range, and, in a second operation mode, maintain the sensor element at a lower temperature range that is above an ambient temperature and that is lower than the higher temperature range.

A cargo body panel includes a composite construction including an interior skin, an exterior skin, and a core positioned between the interior and exterior skins. The panel has parallel first and second edges spaced in a first direction. A pocket is formed by the interior skin at a location spaced away from the first and second edges, the pocket extending parallel to the first and second edges to define a length. The pocket is wide enough to accommodate a logistics profile insert having a width that exceeds a depth of the pocket, the depth measured into the panel, perpendicular to both the first direction and the length.

A thermal, flow measuring device comprising a sensor with a metal sensor housing, which has a hollow body for connecting to a plug-in apparatus and/or a tube or pipe wall, wherein the hollow body has a base area; wherein the sensor housing has at least first and second pin sleeves, which protrude starting from the base area, wherein the metal sensor housing is embodied as one piece and the pin sleeves and the hollow body are connected together seam freely, especially weld seam freely.

A flow rate measurement device includes a housing having a main flow path, a sub flow path formed inside the housing to allow a part of a fluid to be detected flowing through the main flow path, an inlet portion that allows the fluid to be measured flowing in the main flow path to flow into the sub flow path, an outlet portion that allows the fluid to be measured flowing in the sub flow path to flow out to the main flow path, a flow rate detection unit that is provided between the inlet portion and the outlet portion in the sub flow path and detects a flow rate of the fluid to be measured flowing through the sub flow path, and a communication hole that is provided between the flow rate detection unit and the outlet portion and communicates the sub flow path and the main flow path.

A flowmeter is inserted into a main passage through which a target fluid flows. The flowmeter includes a housing, a sub passage, an inlet portion, an outlet portion, a flow rate detector, and a protrusion. The housing includes a side surface and a tip end surface. A part of the target fluid flows into the sub passage from the main passage. The target fluid flows into the sub passage through the inlet portion and flows out of the sub passage through the outlet portion. The flow rate detector is configured to detect a flow rate of the target fluid flowing through the sub passage. The tip end surface includes a first end area and a second end area. The protrusion protrudes from the tip end surface and is located in both the first end area and the second end area.

A flowmeter is configured to measure a flow rate of a gas flowing through a main passage. The flowmeter includes a housing and a flow rate detector. The housing is made of a resin and includes a bypass passage branched off from the main passage. The flow rate detector is disposed in the bypass passage and transmits detection signals in accordance with the flow rate of the gas flowing through the main passage. The housing includes a non-insulation portion including graphite.

A flowmeter is disposed in a passage through which a fluid flows. The flowmeter includes a first passage and a second passage. The first passage defines an opening through which a part of the fluid flows into the flowmeter from the passage. The second passage branches off from the first passage and includes a flow rate detector configured to detect a flow rate of the fluid flowing through the second passage from the first passage. The second passage has one end at which the second passage branches off from the first passage and the other end. The second passage includes at least one end opening at the other end and an inflow reducer configured to restrict the fluid from flowing into the second passage through the at least one end opening.

A physical quantity detector includes a housing, a circuit board, a cover, a resin member, a conductor, and a conductive member. The circuit board includes a board surface. The cover faces the board surface and defines, together with the hosing, a passage through which the target fluid flows. The conductor includes a passage side portion and a connecting portion. The conductive member electrically connects the connecting portion to the circuit board. The conductive member includes a first end in the thickness direction facing a contact target that is either one of the connecting portion or the board surface. The first end includes a contact portion in contact with the contact target and a contactless portion away from the contact target in the thickness direction.
