Furthermore, the terms "first" and "second," etc., are used to distinguish between different objects, not to describe a specific order.

[0050] The following describes the implementation of the present disclosure in detail with reference to the accompanying drawings:

[0051] Figure 1 This is a structural diagram of a first pipeline, a second pipeline and a throttling device provided in an embodiment of the present disclosure. Figure 1 :

[0052] In this embodiment, the first pipe and the second pipe are two parts of the same pipe, and the first pipe and the second pipe are in the same horizontal plane; there is a throttling device between the first pipe and the second pipe, that is, the throttling device physically distinguishes the first pipe from the second pipe; the fluid in the pipe flows from the first pipe to the second pipe; the throttling device can be: an orifice plate, a nozzle and a venturi tube, etc., and the throttling device is used to change the flow rate of the fluid.

[0053] In one embodiment of the present disclosure, reference Figure 2 , the flow measuring device for measuring a gasifiable medium comprises:

[0054] Differential pressure transmitter 10, temperature compensation module 11, pressure compensation module 12, first pressure taking module 13, second pressure taking module 14 and host meter 15;

[0055] The differential pressure transmitter 10 is connected to the first pressure taking module 13 and the second pressure taking module 14 respectively;

[0056] The host meter 15 is connected to the first pressure module 13, the second pressure module 14, the temperature compensation module 11 and the pressure compensation module 12 respectively;

[0057] The temperature compensation module 11 is used to collect the temperature value of the first area of ​​the first pipe and the temperature value of the second area of ​​the second pipe;

[0058] The pressure compensation module 12 is used to collect the pressure value of the third area of ​​the first pipeline and the pressure value of the fourth area of ​​the second pipeline;

[0059] The first pressure sampling module 13 is used to collect the pressure value of the fifth area of ​​the first pipeline;

[0060] The second pressure sampling module 14 is used to collect the pressure value of the sixth area of ​​the second pipeline;

[0061] The host meter 15 is configured to display the flow rate value of the target fluid.

[0062] In this embodiment, the differential pressure transmitter 10 is configured to receive the pressure value of the fifth region of the first pipeline collected by the first pressure sampling module 13 and the pressure value of the sixth region of the second pipeline collected by the second pressure sampling module 14;

[0063] The first area of ​​the first pipeline, the third area of ​​the first pipeline and the fifth area of ​​the first pipeline have no front-to-back relationship;

[0064] The second area of ​​the second pipe, the fourth area of ​​the second pipe, and the sixth area of ​​the second pipe have no anteroposterior relationship;

[0065] The first pressure-taking module 13 and the second pressure-taking module 14 may be pressure sensors.

[0066] For example, there is fluid in the first pipeline and the second pipeline. The first pressure-taking module 13 collects the pressure value of the fifth area of ​​the first pipeline and sends it to the differential pressure transmitter 10. The second pressure-taking module 14 collects the pressure value of the sixth area of ​​the second pipeline and sends it to the differential pressure transmitter 10.

[0067] The temperature compensation module 11 collects the temperature value of the first area of ​​the first pipe and the temperature value of the second area of ​​the second pipe and sends them to the differential pressure transmitter 10. After receiving the temperature value of the first area of ​​the first pipe and the temperature value of the second area of ​​the second pipe, the differential pressure transmitter 10 converts the temperature value into a temperature difference, adjusts the first flow value according to the temperature difference, and outputs the second flow value.

[0068] The pressure compensation module 12 collects the pressure value of the third area of ​​the first pipeline and the pressure value of the fourth area of ​​the second pipeline and sends them to the differential pressure transmitter 10. After receiving the pressure value of the third area of ​​the first pipeline and the pressure value of the fourth area of ​​the second pipeline, the differential pressure transmitter 10 converts them into a pressure difference and adjusts the second flow value according to the pressure difference, and outputs a third flow value. The third flow value is the flow value of the fluid in the pipeline.

[0069] From the above, it can be concluded that the present disclosure connects the first pressure taking module 13 and the second pressure taking module 14 through the differential pressure transmitter 10, and can accurately measure the pressure difference of the fluid; the present disclosure adjusts the flow value by receiving the temperature value collected by the temperature compensation module 11 and the pressure value collected by the pressure compensation module 12 through the host meter 15, thereby improving the accuracy of the flow measurement.

[0070] In one embodiment of the present disclosure, reference Figure 3 , the temperature compensation module 11 includes: a first temperature sensor 111 and a second temperature sensor 112;

[0071] The first temperature sensor 111 is connected to the host meter 15;

[0073] The first temperature sensor 111 is disposed in the first region of the first pipeline;

[0074] The second temperature sensor 112 is disposed in the second region of the second pipe.

[0075] The pressure compensation module 12 includes: a first pressure sensor 121, a second pressure sensor 122 and a pressure difference classification circuit 123;

[0076] The first pressure sensor 121 and the second pressure sensor 122 are both connected to the pressure difference classification circuit 123;

[0077] The pressure difference classification circuit 123 is connected to the host meter 15;

[0078] The first pressure sensor 121 is disposed in the third region of the first pipeline;

[0079] The second pressure sensor 122 is disposed in the fourth region of the second pipe.

[0080] A flow measurement device for measuring a gasifiable medium further comprising: a throttling device 16;

[0081] The throttling device 16 is provided between the first pipe and the second pipe;

[0082] The throttling device 16 is configured to change the flow rate of the target fluid.

[0083] The first pressure taking module 13 includes: a third pressure sensor 131;

[0084] The third pressure sensor 131 is connected to the differential pressure transmitter 10;

[0085] The third pressure sensor 131 is configured to collect a pressure value of the fifth region of the first pipe.

[0086] The second pressure taking module 14 includes: a fourth pressure sensor 141;

[0087] The fourth pressure sensor 141 is connected to the differential pressure transmitter 10;

[0088] The fourth pressure sensor 141 is configured to collect a pressure value of a sixth region of the second pipe.

[0089] A flow measurement device for measuring a gasifiable medium further comprising a storage module 17;

[0090] The storage module 17 is connected to the host table 15;

[0091] The storage module 17 is configured to store the display data of the host table 15 .

[0092] In this embodiment, the differential pressure transmitter 10 is configured to receive the pressure value of the fifth region of the first pipeline acquired by the third pressure sensor 131 and the pressure value of the sixth region of the second pipeline acquired by the fourth pressure sensor 141;

[0093] The pressure difference classification circuit 123 is configured to receive the pressure value collected by the first pressure sensor 121 and the pressure value collected by the second pressure sensor 122 and output pressure difference classification information;

[0094] The host meter 15 is configured to receive the differential pressure data sent by the differential pressure transmitter 10, and adjust and output the flow value of the target fluid according to the temperature information sent by the temperature compensation module 11 and the pressure difference classification information sent by the pressure compensation module 12;

[0095] The target fluid can be liquid nitrogen, water, oil, oxygen, etc.

[0096] The throttling device 16 can be an orifice plate, a nozzle, a venturi tube, etc.

[0097] For example, the target fluid is liquid nitrogen, the throttling device 16 is an orifice plate, and the liquid nitrogen flows from the first pipeline to the second pipeline. The third pressure sensor 131 collects the pressure value at 5 cm from the orifice plate in the first pipeline and sends it to the differential pressure transmitter 10. The fourth pressure sensor 141 collects the pressure value at 3 cm from the orifice plate in the second pipeline and sends it to the differential pressure transmitter 10. After receiving the pressure value at 5 cm from the orifice plate in the first pipeline and the pressure value at 3 cm from the orifice plate in the second pipeline, the differential pressure transmitter 10 converts them into a pressure difference and calculates a first flow rate value of the fluid in the pipeline based on the pressure difference.

[0098] The first temperature sensor 111 collects the temperature value of the first pipe at a distance of 10 cm from the orifice plate and sends it to the differential pressure transmitter 10. The second temperature sensor 112 collects the temperature value of the second pipe at a distance of 10 cm from the orifice plate and sends it to the differential pressure transmitter 10. After receiving the temperature value of the first pipe at a distance of 10 cm from the orifice plate and the temperature value of the second pipe at a distance of 10 cm from the orifice plate, the differential pressure transmitter 10 converts them into a temperature difference, adjusts the first flow value according to the temperature difference, and outputs a second flow value.

[0099] The first pressure sensor 121 collects the pressure value at a distance of 15 cm from the orifice plate in the first pipeline and sends it to the pressure difference grading circuit 123. The second pressure sensor 122 collects the pressure value at a distance of 15 cm from the orifice plate in the second pipeline and sends it to the pressure difference grading circuit 123. After receiving the pressure value at a distance of 15 cm from the orifice plate in the first pipeline and the pressure value at a distance of 15 cm from the orifice plate in the second pipeline, the pressure difference grading circuit 123 converts them into pressure difference grading information and sends it to the host meter 15. The pressure difference grading information can be 1. After receiving the pressure difference grading information as 1, the host meter 15 adjusts the second flow value according to the first step, outputs and displays the third flow value, and sends the third flow value to the storage module 17. The storage module 17 stores the third flow value. The third flow value is the flow value of the fluid in the pipeline.

[0100] From the above, it can be concluded that the present disclosure can realize the grading of the pressure difference between the first pipeline and the second pipeline through the first pressure sensor 121, the second pressure sensor 122 and the pressure difference grading circuit 123. The host meter 15 can use different step sizes to adjust the output flow value according to different pressure difference grading information; the present disclosure realizes data storage through the storage module 17, providing data support for data query and review.

[0101] In one embodiment of the present disclosure, reference Figure 4The pressure difference grading circuit 123 includes: a first non-inverting amplifier 1231, a second non-inverting amplifier 1232, a third non-inverting amplifier 1233, a first comparator 1234, a second comparator 1235, a third comparator 1236 and an adder 1237;

[0102] The first non-inverting amplifier 1231 is connected to the first pressure sensor 121 and the inverting input terminal of the first comparator 1234 respectively;

[0103] The second non-inverting amplifier 1232 is connected to the first pressure sensor 121 and the inverting input terminal of the second comparator 1235 respectively;

[0104] The third non-inverting amplifier 1233 is connected to the first pressure sensor 121 and the inverting input terminal of the third comparator 1236 respectively;

[0105] The second pressure sensor 122 is connected to the non-inverting input terminal of the first comparator 1234, the non-inverting input terminal of the second comparator 1235, and the non-inverting input terminal of the third comparator 1236 respectively;

[0106] The output terminal of the first comparator 1234 , the output terminal of the second comparator 1235 , and the output terminal of the third comparator 1236 are all connected to the input port of the adder 1237 ;

[0107] The output port of the adder 1237 is connected to the host table 15 .

[0108] In this embodiment, the first non-inverting amplifier 1231 may reduce the pressure value collected by the first pressure sensor 121 to a first multiple of the original pressure value, where the first multiple is less than 1. The second non-inverting amplifier 1232 may be a follower amplifier, i.e., the output value remains the original pressure value. The third non-inverting amplifier 1233 may amplify the pressure value collected by the first pressure sensor 121 to a second multiple of the original pressure value, where the second multiple is greater than 1.

[0109] The first comparator 1234 compares the pressure value collected by the second pressure sensor 122 with the first multiple of the pressure value collected by the first pressure sensor 121. If the pressure value collected by the second pressure sensor 122 is greater than the first multiple of the pressure value collected by the first pressure sensor 121, the first comparator 1234 sends a "1" to the adder 1237; otherwise, it sends a "0";

[0110] The second comparator 1235 compares the pressure value collected by the second pressure sensor 122 with the pressure value collected by the first pressure sensor 121. If the pressure value collected by the second pressure sensor 122 is greater than the pressure value collected by the first pressure sensor 121, the second comparator 1235 sends a "1" to the adder 1237; otherwise, it sends a "0";

[0111] The third comparator 1236 compares the pressure value collected by the second pressure sensor 122 with the second multiple of the pressure value collected by the first pressure sensor 121. If the pressure value collected by the second pressure sensor 122 is greater than the second multiple of the pressure value collected by the first pressure sensor 121, the second comparator 1235 sends a "1" to the adder 1237; otherwise, it sends a "0";

[0112] Since the pressure values ​​are all positive, and the value of the inverting input terminal of the first comparator 1234 is less than the value of the inverting input terminal of the second comparator 1235, which is less than the value of the inverting input terminal of the third comparator 1236, the values ​​received by the adder 1237 can only be "000", "100", "110" and "111". When the adder 1237 receives "000", the pressure difference classification information "0" is sent to the host meter 15, and the host meter 15 adjusts the flow value according to the first step length; when the adder 1237 receives "100", the pressure difference classification information "1" is sent to the host meter 15, and the host meter 15 adjusts the flow value according to the second step length; when the adder 1237 receives "110", the pressure difference classification information "2" is sent to the host meter 15, and the host meter 15 adjusts the flow value according to the third step length; when the adder 1237 receives "111", the pressure difference classification information "3" is sent to the host meter 15, and the host meter 15 adjusts the flow value according to the fourth step length.

[0113] For example, the target fluid is liquid oxygen, the first multiple is 4 / 5, the second multiple is 6 / 5, the pressure value collected by the first pressure sensor 121 is x, and the pressure value collected by the second pressure sensor 122 is 9 / 10x. At this time, the first comparator 1234 compares 9 / 10x with 4 / 5x. Since 9 / 10x is greater than 4 / 5x, the first comparator 1234 sends "1" to the adder 1237. The second comparator 1235 compares 9 / 10x with x. Since 9 / 10x is less than 4 / 5x, 4 / 5x, the first comparator 1234 sends "0" to the adder 1237, and the first comparator 1234 compares 9 / 10x with 6 / 5x. Since 9 / 10x is less than 6 / 5x, the first comparator 1234 sends "0" to the adder 1237. At this time, the adder 1237 receives "100", and the adder 1237 outputs the classification as "1" and sends it to the host meter 15. The host meter 15 adjusts the flow value according to the second step size based on the pressure difference classification information being "1".

[0114] From the above, it can be concluded that the present disclosure realizes the grading of pressure difference through the first comparator 1234, the second comparator 1235, the third comparator 1236 and the adder 1237. The host meter 15 can adjust the flow value according to the corresponding step size based on the pressure difference grading information, thereby improving the accuracy and reliability of flow measurement.
