[0023] This invention provides a self-adjusting sensitivity galvanometer device that requires no replacement, mainly comprising a housing 1, a detection mechanism 2, a display mechanism 3, and an adjustment mechanism 4. The specific embodiments of this invention are described in detail below with reference to specific examples and accompanying drawings.

[0024] like Figure 1 As shown, a self-adjusting sensitivity flow meter device that requires no replacement includes a housing 1. The housing 1 is a closed shell used to protect the internal mechanisms from interference and damage from the external environment. A detection mechanism 2 for detecting fluid flow is disposed inside the housing 1, and the detection mechanism 2 is fixedly connected to the housing 1 via a connecting piece. A display mechanism 3 for displaying the detection results is disposed on the upper surface of the housing 1, and the display mechanism 3 includes a display screen 17 and a display panel 18. An adjustment mechanism 4 for adjusting the sensitivity of a flow sensor 5 is disposed on the side wall of the housing 1, and the adjustment mechanism 4 includes an adjustment knob 10 and an adjustment rod 11.

[0025] like Figure 2 As shown, the detection mechanism 2 includes a flow sensor 5 disposed within the housing 1. The flow sensor 5 is used to detect the flow rate of the fluid, and its structure is as follows: Figure 3 As shown. The flow sensor 5 includes a flow detection tube 7, a first sensor 8, and a second sensor 9. The flow detection tube 7 is fixedly installed inside the housing 1 and is used to guide the fluid flow through the detection tube to ensure that the fluid flows stably through the detection area. The first sensor 8 and the second sensor 9 are installed inside the flow detection tube 7 and are symmetrical front to back. The first sensor 8 is used to detect the flow rate of the fluid, while the second sensor 9 is used to detect the flow velocity of the fluid. The first sensor 8 and the second sensor 9 are electrically connected to the signal processor 14 through the first wire 6, respectively, and transmit the detected flow rate signal and flow velocity signal to the signal processor 14.

[0026] The signal transmission unit 6 includes a first wire 6 and a second wire 6. The first wire 6 is used to transmit the flow rate signal and flow velocity signal detected by the first sensor 8 and the second sensor 9 to the signal processor 14. The second wire 6 is used to transmit the signal processed by the signal processor 14 to the display screen 17. The design of the signal transmission unit 6 ensures the stability and reliability of the signal during transmission.

[0027] like Figure 4As shown, the adjustment mechanism 4 includes an adjustment knob 10 and an adjustment rod 11 disposed on the side wall of the housing 1. The adjustment knob 10 is an externally operable knob used to adjust the sensitivity of the flow sensor 5. An inner rod 12 is fixedly mounted on the adjustment knob 10, and the inner rod 12 is threadedly connected to an outer rod 13. The outer rod 13 is connected to the signal processor 14. By rotating the adjustment knob 10, the position of the inner rod 12 within the outer rod 13 is adjusted, thereby adjusting the output parameters of the signal processor 14. The design of the adjustment knob 10 allows the operator to achieve fine adjustment of the sensitivity of the flow sensor 5 through simple manual operation.

[0028] like Figure 5 As shown, the display mechanism 3 includes a display screen 17 and a display panel 18 disposed on the upper surface of the housing 1. The display panel 18 has a flow rate display area 19 and a sensitivity display area 20. The flow rate display area 19 displays the current flow rate of the fluid, and the sensitivity display area 20 displays the current sensitivity of the flow sensor 5. The display panel 18 also has indicator lights, including a green indicator light 21 and a red indicator light 22. The green indicator light 21 indicates that the flow sensor 5 is in a normal sensitivity state, and the red indicator light 22 indicates that the flow sensor 5 is in a high sensitivity state. The indicator light design allows the operator to intuitively understand the current operating status of the flow sensor 5.

[0029] like Figure 2 and Figure 4 As shown, the signal processor 14 includes a microprocessor 15 and a memory 16. The microprocessor 15 is electrically connected to the memory 16, which stores parameter settings for different sensitivities. The microprocessor 15 reads the corresponding parameters from the memory 16 according to the adjustment range of the adjustment lever 11, and adjusts the sensitivity of the flow sensor 5 in real time. The microprocessor 15 is also responsible for processing the signals transmitted from the first sensor 8 and the second sensor 9, calculating the flow rate and velocity values ​​of the fluid through an internal algorithm, and transmitting these data to the display screen 17 for display via the second wire 6.

[0030] like Figure 5 As shown, signal converter 23 includes an A / D converter 24 and a D / A converter 25. The A / D converter 24 is electrically connected to the flow sensor 5 and converts the analog signal detected by the flow sensor 5 into a digital signal. The D / A converter 25 is electrically connected to the display screen 17 and converts the digital signal processed by the microprocessor 15 into an analog signal for display on the display screen 17. The design of signal converter 23 ensures efficient conversion between different signal formats, improving the accuracy and clarity of the displayed data.

[0031] The specific operation process of this utility model is as follows: First, the operator installs the flow meter device on the pipe where the fluid flow rate needs to be detected. When the fluid passes through the flow detection pipe 7, the first sensor 8 detects the fluid flow rate, and the second sensor 9 detects the fluid velocity. The first sensor 8 and the second sensor 9 transmit the detected flow rate signal and velocity signal to the signal processor 14 through the first wire 6, respectively. After receiving these signals, the microprocessor 15 in the signal processor 14 calculates the current fluid flow rate value and velocity value through an internal algorithm, and sends these data to the A / D converter 24 in the signal converter 23 for analog-to-digital conversion. The A / D converter 24 sends the converted digital signal to the microprocessor 15, and the microprocessor 15 then converts these digital signals to analog signals through the D / A converter 25, and finally displays them on the display screen 17.

[0032] In actual use, the operator can adjust the sensitivity of the flow sensor 5 by adjusting the knob 10 according to actual needs. When the adjustment knob 10 is rotated, the position of the inner rod 12 within the outer rod 13 changes, and the adjustment range of the adjustment rod 11 is transmitted to the signal processor 14. The microprocessor 15 in the signal processor 14 reads the corresponding parameters in the memory 16 according to the adjustment range of the adjustment rod 11, and adjusts the sensitivity of the flow sensor 5 in real time. For example, when it is necessary to detect low flow, the operator can rotate the adjustment knob 10 to the high sensitivity position. The microprocessor 15 will read the high sensitivity parameter setting in the memory 16, thereby improving the detection accuracy of the flow sensor 5. At this time, the red indicator light 22 lights up, and the sensitivity display area 20 of the display panel 18 shows that the flow sensor 5 is currently in a high sensitivity state. When high flow needs to be detected, the operator can rotate the adjustment knob 10 to the normal sensitivity position. The microprocessor 15 will read the normal sensitivity parameter setting in the memory 16 to expand the detection range of the flow sensor 5. At this time, the green indicator light 21 will light up, and the sensitivity display area 20 of the display panel 18 will show that the flow sensor 5 is currently in the normal sensitivity state.

[0033] In a specific application scenario, let's assume this flow meter is used in a pipeline flow monitoring system in industrial production. First, the operator installs the flow meter on the pipeline to be monitored, ensuring a proper connection between the flow detection tube 7 and the pipeline, allowing fluid to flow smoothly through it. When low flow rates need to be detected during production, the operator can rotate the adjustment knob 10 to the high-sensitivity position to improve detection accuracy and ensure even minute changes in low flow rates are accurately captured. When high flow rates need to be detected, the operator can rotate the adjustment knob 10 to the normal sensitivity position to expand the detection range and ensure accurate and reliable results for high flow rates. Through such adjustments, the flow meter maintains optimal detection performance under different operating conditions, effectively improving the reliability and stability of the monitoring system.

[0034] The design of the adjustment mechanism 4 and display mechanism 3 in this invention allows operators to easily adjust and view the sensitivity status of the flow sensor 5. The rotation of the adjustment knob 10 is simple and easy, and the intuitive display of the indicator lights allows operators to quickly understand the working status of the flow sensor 5. The flow display area 19 and sensitivity display area 20 on the display panel 18 respectively display the current flow value and sensitivity status, facilitating real-time monitoring of the equipment's operation.

[0035] Furthermore, the design of the microprocessor 15 and memory 16 in the signal processor 14 enables automated and precise adjustment of the sensitivity of the flow sensor 5. The microprocessor 15 automatically reads the corresponding sensitivity parameters from the memory 16 based on the adjustment range of the adjustment lever 11 and adjusts the operating state of the flow sensor 5 in real time, thereby ensuring the accuracy and consistency of the detection results. This design not only reduces operator intervention but also improves the intelligence level of the equipment.

[0036] In summary, this invention provides a self-adjusting sensitivity flow meter device that requires no replacement. Through the coordinated use of the detection mechanism 2, adjustment mechanism 4, and display mechanism 3, it achieves accurate detection of fluid flow rate. Furthermore, the sensitivity of the flow sensor 5 can be adjusted in real time according to actual needs, eliminating the need for sensor replacement, reducing equipment maintenance costs and time, and improving equipment reliability and lifespan. The fine adjustment of the adjustment mechanism 4 and the intuitive display of the display mechanism 3 allow operators to easily operate and monitor the equipment, improving user-friendliness and ease of operation. The design of the signal processor 14 ensures the detection accuracy of the flow sensor 5 under different operating conditions, improving the accuracy and consistency of the detection results. This invention has broad application prospects in pipeline flow monitoring systems in industrial production.
