Temperature probes are provided in the first temperature measuring wing 107 and the second temperature measuring wing 108, and a heating wire is also provided in the second temperature measuring wing 108. A boss is provided on the outer surface of the measuring pipe 101, on which a limiting ring 110 is fixedly installed, and a limiting turntable 119 is rotatably installed in the limiting turntable 119, which is fixedly matched with the temperature measuring wing top seat 109. An adjusting rotating disk 113 is fixedly installed on the limiting turntable 119, and the adjusting rotating disk 113 is fixedly installed on the output shaft of the adjusting motor 112.

[0027] The surfaces of the first temperature measurement wing 107 and the second temperature measurement wing 108 are both provided with elastic resistance strips, and the surfaces of the elastic resistance strips are provided with an elastic insulating coating. An adjustment motor support plate 111 is also fixedly mounted on the restriction ring 110, and the adjustment motor support plate 111 is fixedly engaged with the adjustment motor 112. The restriction turntable 119 is provided with two symmetrically arranged restriction bevels 1191, and each restriction bevel 1191 is also provided with a roller placement groove 1192 on the side. Each two symmetrically arranged restriction bevels 1191 and the symmetrically arranged roller placement grooves 1192 constitute a restriction group, and the restriction groups can be provided with 1-6 groups. Each restriction bevel 1191 is overlapped with an extrusion column 117, which is slidably engaged with the inner wall of the restriction ring 110, and friction exists between the extrusion column 117 and the inner wall of the restriction ring 110. An elastic belt 118 is also provided between the restriction bevel 1191 and the extrusion column 117 to pull the extrusion column 117 into a narrow space. A roller 116 is rotatably installed in the roller placement groove 1192, a sliding chamber 1131 is opened on the adjusting rotating disk 113, and a magnetic block 114 is slidably installed in the sliding chamber 1131.

[0028] The support assembly includes a protective housing 210, with side support perforated plates 211 fixedly mounted on both ends of the protective housing 210. These perforated plates 211 are provided with vents and are fixedly mated to the mounting flange 105. Cooling fans 206 are rotatably mounted on both ends of the inner wall of the protective housing 210, each of which is fixedly mounted with a gear ring 207. A protective cover 212 is fixedly mounted on the outer surface of the protective housing 210, within which a cooling motor 209 is fixedly mounted. Gears 208 are fixedly mounted on both ends of the output shaft of the cooling motor 209, meshing with two gear rings 207. At least three roller brackets 204 are fixedly mounted on the inner wall of the protective housing 210. Each roller bracket 204 is rotatably mounted with rollers 205 spaced 120 degrees apart. The rollers 205 roll in engagement with the surface of the extruded housing 102, which is fixedly mounted on the outer surface of the measuring pipe 101. Fixed support ring plates 202 are provided at both end surfaces of the extruded shell 102. The two fixed support ring plates 202 are fixedly mounted on the corresponding roller brackets 204 through fixing frames 203, and pressure sensors 201 are provided between the two fixed support ring plates 202 and the two end surfaces of the extruded shell 102.

[0029] The operating principle of a multi-scenario flow measurement system disclosed herein is as follows: The device's two mounting flanges 105 are installed in series within a pipeline where flow monitoring is required. As fluid passes through a first temperature-measuring wing 107 and a second temperature-measuring wing 108, a temperature probe within the first temperature-measuring wing 107 detects the fluid's temperature. This then activates a heating wire within the second temperature-measuring wing 108, heating the second temperature-measuring wing 108 to a temperature higher than the fluid's temperature (e.g., 10 degrees Celsius higher). Furthermore, the temperature probe within the second temperature-measuring wing 108 detects its own temperature and provides feedback, allowing the internal heating wire to regulate the temperature of the second temperature-measuring wing 108 in real time. In other words, as the fluid flow rate increases, more heat is removed from the second temperature-measuring wing 108. The faster the heat decays, the faster the fluid flow rate. Furthermore, to maintain the internal temperature of the second temperature-measuring wing 108, the heating wire needs to be continuously heated, consuming more power (increasing power consumption also requires an increase in the current supplied by the heating wire). When it is necessary to measure a fluid that cannot be heated, it is only necessary to control the output shaft of the adjusting motor 112. The output shaft of the adjusting motor 112 will drive the adjusting rotating disk 113 to rotate. The rotation of the adjusting rotating disk 113 will drive the limiting rotating disk 119 to rotate. When the adjusting motor 112 is started, the internal winding will generate magnetic force, thereby attracting the magnetic block 114 upward. The magnetic block 114 pulls the extrusion column 117 to move through the unlocking belt 115 (overcoming the elastic force of the elastic belt 118), so that the extrusion column 117 moves toward the roller 116, that is, the limiting inclined surface 1191 and the inner wall of the limiting ring 110 are not in a hurry to squeeze the column 117. At this time, the limiting rotating disk 119 can rotate normally, and the limiting rotating disk 119 can rotate normally. The rotation of the disk 119 will drive the temperature measuring wing top seat 109 to rotate. At this time, the temperature measuring wing top seat 109 will change the angle between the first temperature measuring wing 107 and the second temperature measuring wing 108 and the fluid flow direction. That is to say, when the fluid flows through the first temperature measuring wing 107 and the second temperature measuring wing 108, the first temperature measuring wing 107 and the second temperature measuring wing 108 will be deformed by the impact of the fluid, which will also cause the resistance of the elastic resistor strip on its surface to change. The greater the deformation, the faster the fluid flow rate. At the same time, the greater the resistance of the elastic resistor strip, the smaller the current passing through. Therefore, by measuring the magnitude of the current, the flow rate of the fluid can also be measured, and the flow rate can be obtained.When the fluid impacts the first temperature measuring wing 107 and the second temperature measuring wing 108, a force is applied to the first temperature measuring wing 107 and the second temperature measuring wing 108, causing the first temperature measuring wing 107 and the second temperature measuring wing 108 to have a tendency to rotate. The first temperature measuring wing 107 and the second temperature measuring wing 108 transmit the torque to the temperature measuring wing top seat 109, and then the temperature measuring wing top seat 109 transmits the torque to the limiting turntable 119, causing the limiting turntable 119 to have a tendency to rotate. At this time, the adjustment motor 112 is not started, that is, the extrusion column 117 is driven by the elastic belt 118 toward and away from the roller 116 , at this time, the limiting slope 1191 and the limiting ring 110 will squeeze the extrusion column 117, and the rotation of the limiting slope 1191 will drive the extrusion column 117 to rotate, and one of the extrusion columns 117 is subjected to the friction force of the limiting ring 110 and the pulling direction of the elastic belt 118, which further increases the extrusion force of the limiting slope 1191 and the limiting ring 110 on the extrusion column 117, so that the extrusion column 117 is stuck between the limiting slope 1191 and the limiting ring 110, which makes the first temperature measuring wing 107 and the second temperature measuring wing 108 unable to rotate, and can only rotate when the adjustment motor 112 is started.

[0030] When the first and second temperature measuring wings 107 and 108 are impacted by the fluid, the impact force is transmitted axially to the measuring pipe 101, and then to the extrusion housing 102. The extrusion housing 102 squeezes the pressure sensor 201 (because the protective housing 210 is stationary and the fixed support ring plate 202 is fixed to the protective housing 210 via the fixing frame 203 and the roller bracket 204, the pressure sensor 201 is squeezed). The pressure sensor 201 measures the magnitude of the fluid pressure exerted on the first and second temperature measuring wings 107 and 108, thereby reflecting the flow rate of the fluid and, therefore, the flow rate of the fluid. The swing angle of the first and second temperature measuring wings 107 and 108 is controlled by the adjustment motor 112. Therefore, the measurement sensitivity can be adjusted by adjusting the swing angle of the first and second temperature measuring wings 107 and 108 (the angle between them and the flow direction of the fluid). The larger the angle, the greater the pressure exerted on the pressure sensor 201.

[0031] When working in a high temperature environment, the heat dissipation motor 209 is started, and the two ends of the output shaft of the heat dissipation motor 209 drive the gear 208 to rotate. The gear 208 drives the heat dissipation fan 206 to rotate through the gear ring 207. The rotation of the heat dissipation fan 206 dissipates heat to the components inside the protective shell 210.
