A flow speed sensor arrangement is provided for measuring a flow speed of a fluid stream relative to an object. The arrangement comprises a first obstructive body having a first forward facing surface and two lateral edges and a second obstructive body having a second forward facing surface. The second obstructive body is positioned in tandem relative to the first obstructive body so that the first and second forward facing surfaces face the same direction and so that when the first forward facing surface is presented to an incoming fluid stream, the first obstructive body is between the incoming fluid flow and the second obstructive body. A sensor array is disposed on the second forward facing surface. The first and second obstructive bodies are attachable to the object so that the first forward face is presented to an incoming fluid stream when the object is immersed in the fluid stream.

A flow meter for measuring the flow rate of a fluid, with a measuring tube that forms a measurement chamber through which the fluid can flow and with at least one bluff body that is disposed in the measurement chamber and wherein, additionally, a measuring body, which can be displaced due to the formation of vortices at the bluff body, is disposed downstream of the bluff body in the measurement chamber. The flow meter has at least one protrusion protruding into the measurement chamber and is formed upstream of the bluff body at an inner wall delimiting the measurement chamber.

A device and a method for determining the flow velocity of a fluid in a hollow body, including at least one disturbance device disposed in the hollow body and at least one sensor for identifying disturbances that are induced in the flow by the disturbance device, which is disposed at a certain distance downstream in the direction of flow from the disturbance device, wherein the disturbance device includes means for generating changeable disturbances in the fluid flow.

The invention discloses an electrical connector. The electrical connector includes a main body, a connection part, a first temperature-sensing element and a second temperature-sensing element, wherein: the connection part electrically connects the main body with a charging element arranged in a flow channel; The main body includes a first side and a second side parallel to the flow direction of the fluid, and the first temperature sensing element and the second temperature sensing element are respectively arranged on the first side and the second side opposite to each other in an electrically insulating manner. The invention also discloses a fluid state testing device and a fluid heat exchange system with electrical connectors. The electrical connector, fluid state testing device and fluid heat exchange system of the present invention can realize measurement and monitoring of fluid flow rate; measurement and monitoring of fluid pressure; measurement and monitoring of fluid resistance; measurement and monitoring without affecting the fluid flow field At least one purpose of the lateral vibration frequency of the electrical connector and suppressing the longitudinal vibration and / or lateral vibration of the electrical connector.

The invention relates to an intelligent pipeline flow velocity monitor, and belongs to the field of fluid monitoring. An inner tube in a pipeline is divided into a left cavity and a right cavity by a separator plate. The left cavity is internally provided with a circuit board, and the end portion thereof is equipped with a left end cover; left and right half shafts of a pin shaft are sleeved by a buffer spring and a balance spring respectively; the left half shaft extends out of the left end cover, and the end portion thereof is equipped with an exciter; the right half shaft extends into the right cavity from the separator plate; a right end cover enables two outer frames and at least one inner frame to be pressed in the right cavity; a metal substrate is pressed between the adjacent inner and outer frames and between the inner frames; a cantilever beam of each metal substrate is bonded with a piezoelectric wafer to form a piezoelectric vibrator, and the other end of the cantilever beam is fixed to the right half shaft; and one side of each outer frame and the two sides of each inner frame are provided with a limit surface and a sediment groove. The advantages are that power generation and flow velocity automatic measurement are realized synchronously through a coupling effect, and thus online monitoring of the flow velocity can be realized in a true sense; the monitor, configured along the length direction of the pipeline, is simple in structure and small in radial dimension, and can obtain required energy through the multiple piezoelectric vibrators easily; and each piezoelectric vibrator is reasonable in structure, large in generated energy and high in reliability.
