Description

Technical Field

[0001] The present application belongs to the field of fluid flow meter detection, and specifically relates to a fluid flow meter detection device, a detection system and a detection method. Background Art

[0002] With the development of science and technology, fluid flow meters have been widely used, covering many fields such as metallurgy, electricity, chemical industry, petroleum, transportation, environmental protection and daily life. The accurate measurement of flow meters is crucial to improving production efficiency, ensuring production safety, reducing energy waste, and fair trade settlement.

[0003] As a national statutory measuring instrument, flow meters are usually factory inspected before leaving the factory to meet the measurement accuracy specified by national standards or industry standards. However, after the meter is installed and put into operation, the accuracy of the meter will change due to factors such as meter scaling, wear and tear, and attenuation of meter components, resulting in errors in measurement accuracy or even measurement errors. Taking water meters as an example, as electromechanical water meters are used online, especially in northern China, scaling will form inside the water meter cavity, causing the water meter cavity to become smaller. Due to the reduction effect, the flow rate of water flowing through the water meter becomes faster and the water pressure becomes greater, causing the impeller used for measurement in the mechanical water meter to rotate faster, causing the water meter measurement value to become larger, resulting in a large measurement error, which in turn causes unfairness in trade settlement. However, due to the long-term lack of convenient and effective detection devices and detection methods that can detect the measurement accuracy of online water meters, the measurement errors and errors of online water meters have long been ignored, seriously affecting the fairness of trade settlement. Similarly, other fluid flow meters such as oil meters also have similar problems. Therefore, there is an urgent need for a portable or mobile fluid flow meter with convenient detection device and detection method, so as to conduct regular sampling or inspection of various fluid flow meters running online to ensure fair trade settlement.

[0054] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] like Figures 1 to 5 As shown, the fluid flow meter detection device includes: a connecting joint 10, a standard flow meter 20 and an intelligent component 30.

[0056] The connecting connector 10 is connected to the input end of the standard flow meter 20. The connecting connector 10 is used to connect the flow meter 002 to be tested. The standard flow meter 20 is electrically connected to the smart component 30. The smart component 30 is used to obtain the flow value of the standard flow meter 20 to determine whether the flow meter 002 to be tested is accurate.

[0057] In the embodiment of the present application, since the connection joint 10 is connected to the input end of the standard flow meter 20, when it is necessary to detect the flow meter 002 to be detected, the connection joint 10 can be directly connected to the flow meter 002 to be detected, so that the fluid flowing through the flow meter 002 to be detected can flow into the connection joint 10, and flow to the standard flow meter 20 through the connection joint 10, so that the standard flow meter 20 can detect the flow of the fluid flowing through the flow meter 002 to be detected. Since the standard flow meter 20 is electrically connected to the smart component 30, the smart component 30 can obtain the measurement value of the standard flow meter 20, and can compare the measurement value with the measurement value of the flow meter 002 to be detected to determine whether the flow meter 002 to be detected is accurate. That is, in the embodiment of the present application, by setting the standard flow meter 20 and the smart component 30, when the standard flow meter 20 detects the fluid flowing through the flow meter 002 to be detected, the smart component 30 can obtain the measurement value of the standard flow meter 20 in real time, and then compare the measurement value with the measurement value of the flow meter 002 to be detected to determine whether the flow meter 002 to be detected is accurate. That is, in the embodiment of the present application, the fluid flow meter detection device can more conveniently determine whether the flow meter 002 to be detected is accurate or whether it has a fault.

[0058] It should be noted that in actual applications, when it is necessary to test the flow meter 002 to be tested, it can be connected to the connecting joint 10 through a hose, and the hose can be connected to the outflow pipe of the flow meter 002 to be tested. Therefore, after the fluid flowing through the flow meter 002 to be tested flows to the outflow pipe, it can flow through the hose to the connecting joint 10, and then flow into the standard flow meter 20 through the connecting joint 10, which is equivalent to the standard flow meter 20 and the flow meter 002 to be tested The same fluid is tested, so that the measurement value of the standard flow meter 20 can be obtained by the smart component 30, and the smart component 30 can determine whether the flow meter 002 to be tested is accurate based on the measurement value of the standard flow meter 20.

[0059] In addition, in the embodiment of the present application, the smart component 30 may be a circuit board with a control function. Of course, the smart component 30 may also be other types, for example, the smart component 30 is a chip with a control function, and another example is that the smart component 30 is a host computer with a control function. The specific type of the smart component 30 is not limited in the embodiment of the present application.

[0060] In addition, in some embodiments, Figure 4 As shown, the fluid flow meter detection device may further include a verification component 40, which is located at the lower side of the fluid outflow end of the standard flow meter 20, and is used to verify whether the standard flow meter 20 is accurate.

[0061] Since the verification component 40 is located on the lower side of the fluid outflow end of the standard flow meter 20, the standard flow meter 20 can be verified through the verification component 40, that is, the accuracy of the standard flow meter 20 can be verified through the verification component 40. Therefore, in actual applications, when using the fluid flow meter detection device to detect the flow meter 002 to be detected in the residents' homes, once the residents have doubts about the detection of the standard flow meter 20, the standard flow meter 20 can be tested on-site through the verification component 40, thereby ensuring the accuracy of the measurement values ​​detected by the standard flow meter 20, and further allowing the residents to be convinced of the measurement values ​​detected by the fluid flow meter detection device.

[0062] In addition, in some embodiments, Figure 3 or Figure 4 As shown, the verification component 40 may include a container 41 and a weighing component 42; the container 41 is arranged on the weighing component 42, and the fluid outflow end of the standard flow meter 20 faces the container 41, so that the fluid flowing out of the standard flow meter 20 can flow into the container 41, the weighing component 42 and the smart component 30 can be electrically connected, the weighing component 42 is used to weigh the container 41 and the mass of the fluid flowing into the container 41, and the smart component 30 is used to obtain the mass weighed by the weighing component 42, and verify whether the standard flow meter 20 is accurate based on the mass weighed by the weighing component 42.

[0063] Since the container 41 is arranged on the weighing part 42, and the fluid outflow end of the standard flow meter 20 faces the container 41, when the flow meter 002 to be tested is tested, after the fluid flowing through the flow meter 002 to be tested flows through the standard flow meter 20, the fluid flowing out of the standard flow meter 20 can flow into the container 41, and the weighing part 42 can weigh the container 41 and the fluid in the container 41 to determine the mass of the container 41 and the fluid in the container 41, and then verify whether the standard flow meter 20 is accurate based on the mass weighed by the weighing part 42, combined with the flow value, measurement duration, and unit volume mass of the standard flow meter 20. The weighing part 42 is electrically connected to the smart component 30, and the mass weighed by the weighing part 42 can be obtained by the smart component 30 in real time, and the smart component 30 can automatically verify whether the standard flow meter 20 is accurate based on the mass weighed by the weighing part 42. That is, by providing the receiving member 41 and the weighing member 42, it is possible to easily determine whether the standard flow meter 20 is accurate.

[0064] It should be noted that after the smart component 30 obtains the mass measured by the weighing piece 42, it can determine the flow rate, flow rate and other parameter values ​​of the fluid flowing out of the standard flow meter 20 based on the mass and the measurement time, and the flow rate determined by the smart component 30 is accurate, and then the smart component 30 can compare the determined flow rate with the measured value of the obtained standard flow meter 20 to determine whether the standard flow meter 20 is accurate. Specifically, if the flow rate determined by the smart component 30 is equal to the measured value of the standard flow meter 20, or the difference between the two is less than or equal to the set threshold, it indicates that the standard flow meter 20 is accurate. On the contrary, if the difference between the two is greater than the set threshold, it indicates that the standard flow meter 20 is inaccurate.

[0065] In addition, in the embodiments of the present application, Figure 4 As shown, the container 41 can also be connected to the first valve 140. When the first valve 140 is opened, the fluid in the container 41 can flow out of the container 41 through the first valve 140. When the first valve 140 is closed, the fluid in the container 41 can be stored in the container 41, that is, the fluid in the container 41 cannot flow out of the first valve 140.

[0066] Of course, in the embodiment of the present application, the verification component 40 can also be of other types, as long as the verification component 40 can directly or indirectly determine the flow of the standard flow meter. The specific type of the verification component 40 is not limited in the embodiment of the present application.

[0067] In addition, in some embodiments, Figure 5As shown, the fluid flow meter detection device can also include a mobile frame 50; the mobile frame 50 includes a frame body 51 and a rolling wheel 52 connected to the frame body 51, the frame body 51 has a first accommodating component 511 and a second accommodating component 512, and in the direction of gravity, the first accommodating component 511 is located above the second accommodating component 512; the weighing component 42 is arranged on the second accommodating component 512, and the connecting joint 10, the standard flow meter 20, the pressure gauge 110, the temperature gauge 120 and the intelligent component 30 are all arranged on the first accommodating component 511.

[0068] Since the weighing member 42 is arranged on the second receiving member 512, the connecting joint 10, the standard flow meter 20 and the intelligent component 30 are all arranged on the first receiving member 511, it is equivalent to that the standard flow meter 20 is located above the weighing member 42 in the direction of gravity, that is, the standard flow meter 20 is located above the receiving member 41, so that when the flow meter 002 to be tested is tested, once the fluid flowing through the flow meter 002 to be tested flows through the standard flow meter 20, the fluid flowing out of the standard flow meter 20 can directly flow into the receiving member 41 by gravity, that is, the fluid flowing out of the standard flow meter 20 can flow into the receiving member 41, so as to facilitate the verification of the standard flow meter 20. In addition, the frame 51 is connected with a rolling wheel 52, so that the frame 51 can be moved by moving the rolling wheel 52, and then the standard flow meter 20 and other components can be moved, so that when the flow meter to be tested in the resident's home is tested, the operator can move the mobile frame 50 and move the standard flow meter 20 and other components to the resident's home for testing.

[0069] It should be noted that the scroll wheel 52 may be a universal wheel. In addition, the number of the scroll wheels 52 may be set according to actual needs, for example, the number of the scroll wheels 52 is 4, and for another example, the number of the scroll wheels 52 is 8. This is not limited in the embodiments of the present application.

[0070] In addition, a fluid hole can be set on the first accommodating member 511, the accommodating member 41 faces the fluid hole, and the fluid outflow end of the standard flow meter 20 faces the fluid hole, so that the fluid flowing out of the standard flow meter 20 can flow into the accommodating member 41 through the fluid hole.

[0071] In addition, in some embodiments, Figure 5 As shown, a drag component 60 may be connected to the frame 51 , and the drag component 60 is used to drag the frame 51 to move.

[0072] Since the frame 51 is connected with the drag assembly 60, when the frame 50 needs to be moved, the frame 51 can be directly dragged and moved by the drag assembly 60. That is, by setting the drag assembly 60, it is convenient to move the frame 50, and then to move the standard flow meter 20 and other components.

[0073] It should be noted that, in the embodiment of the present application, the drag component 60 can be a retractable drag component. Specifically, the drag component 60 can be formed by an electric telescopic rod. Of course, the drag component 60 can also be formed by a non-electric telescopic rod. Of course, the drag component 60 can also be non-retractable, that is, the drag component 60 includes a drag rod, and the drag rod cannot be retracted.

[0074] In addition, in some embodiments, Figure 1 or Figure 3 As shown, the fluid flow meter detection device can also include a box body 70 and a display module 80; the display module 80 is arranged in the box body 70; the connecting joint 10 and the standard flow meter 20 are both located in the box body 70, and a first through hole is arranged on the box body 70, the first through hole faces the connecting joint 10, and the smart component 30 is electrically connected to the display module 80.

[0075] Since the display module 80 is arranged in the box body 70 and the smart component 30 is electrically connected to the display module 80, the smart component 30 can control the display module 80 to display so that the display module 80 can display corresponding information. For example, the display module 80 displays information on whether the standard flow meter 20 is accurate. For another example, the display module 80 displays the mass weighed by the weighing piece 42. In addition, the angle of the display module 80 relative to the box body 70 can be adjusted according to actual needs to facilitate the operator to see the content displayed by the display module 80.

[0076] In addition, in the embodiment of the present application, the display module 80 can be movable relative to the box body 70, and the display module 80 can also cover the box body 70, that is, when the fluid flow meter detection device is not needed, the display module 80 is covered with the box body 70, that is, the display module 80 is in contact with the box body 70; when the fluid flow meter is used, the display module 80 is unfolded, that is, the display module 80 is away from the box body 70, so that the operator can easily view the display module 80. Of course, the display module 80 can also be fixed to the box body 70.

[0077] In addition, the connection joint 10 and the standard flow meter 20 are both located in the box 70, so that the operator can directly move the standard flow meter 20 and other components to the required position by carrying the box 70, and the box 70 can protect the standard flow meter 20 to avoid the problem that the standard flow meter 20 may be easily damaged. In addition, a first through hole is provided on the box 70, and the first through hole faces the connection joint 10. Through such a setting, when it is necessary to test the flow meter 002 to be tested, the connection joint 10 can be directly connected to the flow meter 002 to be tested, avoiding the problem that the connection joint 10 is blocked and difficult to connect.

[0078] It should be noted that in the embodiment of the present application, the display module 80 may be an LED display screen. Of course, the display module 80 may also be other types, for example, the display module 80 is an LCD display screen. The specific type of the display module 80 is not limited in the embodiment of the present application.

[0079] In addition, in the embodiment of the present application, the display module 80 and the box body 70 may be hinged via a hinge, so that the display module 80 is movable relative to the box body 70 .

[0080] In addition, in an embodiment of the present application, the connecting joint 10 can be flush with the outer wall of the box body 70, that is, the box body 70 can have a recessed portion, and a first through hole is set at the bottom of the recessed portion, and the connecting joint 10 can be passed through the first through hole, and the connecting joint 10 is located in the recessed portion and is flush with the outer wall of the box body 70, or the connecting joint 10 is retracted in the recessed portion, which can effectively avoid the problem that the connecting joint 10 protrudes from the outer wall of the box body 70, causing the connecting joint 10 to be easily damaged.

[0081] In addition, in the embodiment of the present application, the smart component 30 can be located in the box 70, so that the box 70 can protect the smart component 30 and avoid the problem of easy damage to the smart component 30.

[0082] In addition, in some embodiments, Figure 1 As shown, the box body 70 is movably connected to the box cover 71 , and the display module 80 is fixed to the surface of the box cover 71 facing the box body 70 . The box cover 71 can drive the display module 80 to move relative to the box body 70 .

[0083] Since the display module 80 is fixed to the surface of the box cover 71 facing the box body 70, and the box body 70 is movably connected to the box body 70, the box cover 71 can be moved to drive the display module 80 to move, that is, the display module 80 can be moved relative to the box body 70. Specifically, in actual application, if the fluid flow meter detection device is not needed, the box cover 71 can be closed on the box body 70, and the box cover 71 can protect the display module 80 and prevent the display module 80 from being easily damaged; when the fluid flow meter detection device is needed, the box cover 71 can be opened, which is equivalent to unfolding the display module 80 relative to the box body 70, and the operator can view the content displayed by the display module 80.

[0084] It should be noted that the box cover 71 and the box body 70 may be connected via a hinge, so that the box cover 71 is movable relative to the box body 70 .

[0085] In addition, in some embodiments, Figure 3As shown, the fluid flow meter detection device may further include an input module 90 , which is disposed on the outer wall of the housing 70 and is electrically connected to the smart component 30 , and is used to input information and instructions to the smart component 30 .

[0086] Since the input module 90 is disposed on the outer wall of the box body 70 and the input module 90 is electrically connected to the smart component 30, when using the fluid flow meter detection device, the operator can input information and instructions to the smart component 30 through the input module 90, so that the smart component 30 performs corresponding control. That is, by providing the input module 90, it is easy to operate to input information and instructions to the smart component 30.

[0087] It should be noted that the input module 90 may be an input keyboard.

[0088] Of course, in the embodiment of the present application, the display module 80 may also have a touch output function, and the operator may also directly click or slide on the display module 80, thereby inputting information and instructions to the smart component 30 through the display module 80. That is, the display module 80 has an input function, and in this case, the input module 90 may not be used, which can save costs.

[0089] In addition, in some embodiments, Figure 3 As shown, the fluid flow meter detection device may also include a box 70 and a display module 80; the display module 80 is arranged in the box 70; the connection joint 10, the standard flow meter 20 and the verification component 40 are all located in the box 70, and a first through hole is arranged on the box 70, and part of the connection joint 10 passes through the first through hole, and the smart component 30 is electrically connected to the display module 80. Through such a setting, the box 70 can protect the standard flow meter 20 and the verification component 40 to avoid the problem that the standard flow meter 20 and the verification component 40 are easily damaged, and through such a setting, the fluid flow meter device can also be made easy to carry, that is, when the operator carries it, the standard flow meter 20, the verification component 40 and other components can be carried by carrying the box 70, which is convenient for the operator to carry.

[0090] In addition, in some embodiments, Figure 1 As shown, the fluid flow meter detection device may further include a communication module 100 , which is electrically connected to the smart component 30 , and the communication module 100 is used to connect to a handheld mobile terminal 1000 and / or a server for communication.

[0091] Since the communication module 100 is electrically connected to the smart component 30, in actual application, the user's handheld mobile terminal 1000 can be electrically connected to the communication module 100, so that the user can send instructions to the smart component 30 through the handheld mobile terminal 1000, or the smart component 30 sends corresponding information to the handheld mobile terminal 1000, so that the user can see the corresponding information on the handheld mobile terminal 1000. That is, by setting the communication module 100, the communication between the user's handheld mobile terminal 1000 and the smart component 30 can be facilitated.

[0092] It should be noted that the communication module 100 may be a Bluetooth module, or a WIFI module, so that the handheld mobile terminal 1000 and the smart component 30 can be interconnected or networked. In addition, the handheld mobile terminal 1000 includes but is not limited to a mobile phone, a tablet computer, and the like.

[0093] In addition, in some embodiments, Figure 1 As shown, the fluid flow meter detection device can also include a first pipeline 001; the connecting joint 10 is connected to the input end of the standard flow meter 20 through the first pipeline 001, and at least one of the pressure gauge 110 and the thermometer 120 is connected to the first pipeline 001; the pressure gauge 110 and the thermometer 120 are both electrically connected to the smart component 30, and the smart component 30 is also used to obtain the pressure value of the pressure gauge 110 and / or the temperature value of the thermometer 120.

[0094] By setting at least one of the pressure gauge 110 and the temperature gauge 120, and both the pressure gauge 110 and the temperature gauge 120 are electrically connected to the smart component 30, the smart component 30 can obtain the pressure value of the pressure gauge 110 and / or the temperature value of the temperature gauge 120, and can determine whether the metering accuracy of the flow meter 002 to be tested is accurate based on the measurement value of the standard flow meter 20 combined with the pressure value of the pressure gauge 110 and / or the temperature value of the temperature gauge 120.

[0095] Among them, one end of the first pipeline 001 is connected to the connecting joint 10 , and the other end of the first pipeline 001 is connected to the inlet end of the standard flow meter 20 .

[0096] It should be noted that in the embodiments of the present application, the fluid flow meter detection device may include only the pressure gauge 110 , the fluid flow meter detection device may include only the temperature gauge 120 , or the fluid flow meter detection device may include both the pressure gauge 110 and the temperature gauge 120 .

[0097] In addition, in some embodiments, Figure 1As shown, the fluid flow meter detection device may further include a second valve 130; the second valve 130 is connected to the fluid outflow end of the standard flow meter 20. Through such a setting, the opening or closing of the second valve 130 can be controlled to control whether the fluid flows out from the fluid outflow end of the standard flow meter 20. Specifically, when the second valve 130 is opened, the fluid can flow out through the standard flow meter 20, and when the second valve 130 is closed, the fluid cannot flow out through the standard flow meter 20.

[0098] In addition, in the embodiment of the present application, the outflow end of the second valve 130 can be directed toward the receiving member 41 , so that the fluid flowing out of the second valve 130 can flow into the receiving member 41 .

[0099] In the embodiment of the present application, since the connection joint 10 is connected to the input end of the standard flow meter 20, when it is necessary to detect the flow meter 002 to be detected, the connection joint 10 can be directly connected to the flow meter 002 to be detected, so that the fluid flowing through the flow meter 002 to be detected can flow into the connection joint 10, and flow to the standard flow meter 20 through the connection joint 10, so that the standard flow meter 20 can detect the flow of the fluid flowing through the flow meter 002 to be detected. Since the standard flow meter 20 is electrically connected to the smart component 30, the smart component 30 can obtain the measurement value of the standard flow meter 20, and can compare the measurement value with the measurement value of the flow meter 002 to be detected to determine whether the flow meter 002 to be detected is accurate. That is, in the embodiment of the present application, by setting the standard flow meter 20 and the smart component 30, when the standard flow meter 20 detects the fluid flowing through the flow meter 002 to be detected, the smart component 30 can obtain the measurement value of the standard flow meter 20 in real time, and then compare the measurement value with the measurement value of the flow meter 002 to be detected to determine whether the flow meter 002 to be detected is accurate. That is, in the embodiment of the present application, the fluid flow meter detection device can more conveniently determine whether the flow meter 002 to be detected is accurate or whether it has a fault.

[0100] The present application embodiment provides a fluid flow meter detection system, such as Figure 6 As shown, the fluid flow meter detection system includes a handheld mobile terminal 1000 and a fluid flow meter detection device in any of the above embodiments.

[0101] The smart component 30 is connected to the handheld mobile terminal 1000 for communication, and the flow meter 002 to be detected is connected to the handheld mobile terminal 1000 for communication.

[0102] Among them, the smart component 30 is communicatively connected with the handheld mobile terminal 1000, and the flow meter to be detected 002 is communicatively connected with the handheld mobile terminal 1000, so that when it is necessary to detect the flow meter to be detected 002, the fluid flow meter can be associated and interconnected with the flow meter to be detected 002 on the handheld mobile terminal 1000, and the measurement data can be collected, recorded and transmitted.

[0103] The present application embodiment provides a fluid flow meter detection system, such as Figure 7 and Figure 8 As shown, the fluid flow meter detection system includes a server 2000, a handheld mobile terminal 1000 and a fluid flow meter detection device in any of the above embodiments; the server 2000 is communicatively connected to the handheld mobile terminal 1000, the smart component 30 is communicatively connected to the server 2000, and the flow meter 002 to be detected is communicatively connected to the server 2000.

[0104] Among them, the server 2000 is communicatively connected with the handheld mobile terminal 1000, the smart component 30 is communicatively connected with the server 2000, and the flow meter to be detected 002 is communicatively connected with the server 2000. Therefore, when it is necessary to detect the flow meter to be detected 002, the fluid flow meter detection device can be associated with the flow meter to be detected 002 on the handheld mobile terminal 1000, and the detection value of the flow meter to be detected 002 and / or the measurement value of the standard flow meter 20 can be uploaded to the server 2000.

[0105] The present application embodiment provides a fluid flow meter detection method, which is applied to the fluid flow meter detection device in any of the above embodiments, such as Fig. 9 As shown, the fluid flow meter detection method includes:

[0106] Step 901: When the connecting joint is connected to the flow meter to be tested, a first measurement value of the flow meter to be tested and a second measurement value of the standard flow meter are obtained.

[0107] Among them, once the connecting joint is connected to the flow meter to be detected, it indicates that the flow meter to be detected needs to be detected, so that the first measurement value of the flow meter to be detected and the second measurement value of the standard flow meter can be obtained. Specifically, the flow meter to be detected can be connected to the handheld mobile terminal for communication, and the handheld mobile terminal is connected to the smart component for communication, so that the first measurement value can be sent to the smart component through the handheld mobile terminal, and the smart component is electrically connected to the standard flow meter, so that the smart component can directly obtain the second measurement value of the standard flow meter. Of course, the flow meter to be detected can also be directly connected to the smart component of the fluid flow meter detection device for communication, that is, the flow meter to be detected is connected to the communication module for communication, and the flow meter to be detected sends the first measurement value to the smart component through the communication module, so that the smart component obtains the first measurement value, and the smart component can directly obtain the second measurement value.

[0108] Step 902: Compare the first measurement value and the second measurement value. If the difference between the first measurement value and the second measurement value is within the preset difference range, it is determined that the flow meter to be tested is accurate. If the difference between the first measurement value and the second measurement value is not within the preset difference range, it is determined that the flow meter to be tested is inaccurate.

[0109] Among them, once the intelligent component obtains the first measurement value and the second measurement value, the intelligent component can compare the first measurement value with the second measurement value. Once it is determined that the difference between the first measurement value and the second measurement value is within the preset difference range, it can be directly determined that the flow meter to be tested is accurate. Conversely, if it is determined that the difference between the first measurement value and the second measurement value is not within the preset difference range, it is determined that the flow meter to be tested is inaccurate.

[0110] In addition, in some implementations, the fluid flow meter detection method further includes: when it is determined that the flow meter to be detected is inaccurate, outputting prompt information, where the prompt information is used to identify that the flow meter to be detected is inaccurate.

[0111] Once it is determined that the flow meter to be tested is inaccurate, the smart component can output a prompt message. Specifically, the smart component can control the display module to display the content indicating that the flow meter to be tested is inaccurate.

[0112] In the embodiment of the present application, the smart component can be electrically connected to a prompting member, which includes but is not limited to an indicator light, a buzzer, etc. At this time, once the smart component determines that the flow meter to be tested is inaccurate, the smart component can control the prompting member to operate and send out a prompt signal. The prompting member can be installed on the box body, or the prompting member can be installed on the frame body.

[0114] Step 1001: When the connection connector is connected to the flow meter to be tested, the device identification information of the flow meter to be tested is associated with the device identification information of the fluid flow meter detection device.

[0115] After associating the device identification information of the flow meter to be tested with the device identification information of the fluid flow meter detection device, the flow meter to be tested and the fluid flow meter detection device can be paired, thereby facilitating subsequent recording, comparison and judgment.

[0116] Step 1002: Obtain a first measurement value of the flow meter to be tested and a second measurement value of a standard flow meter.

[0117] The implementation of step 1002 may refer to the implementation of step 901 and will not be described in detail here.

[0118] Step 1003: Compare the first measurement value and the second measurement value. If the difference between the first measurement value and the second measurement value is within the preset difference range, it is determined that the flow meter to be tested is accurate. If the difference between the first measurement value and the second measurement value is not within the preset difference range, it is determined that the flow meter to be tested is inaccurate.
