[0022] In order to more clearly illustrate the technical scheme in the embodiments of the present utility model and prior art, the specific implementation of the present utility model will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present utility model, and for those skilled in the art, other figures can be obtained from these figures without creative labor, and other embodiments can be obtained. In addition, the design direction belongs to only represent the relative position relationship between components, not the absolute position relationship.

[0023] The utility model embodiment provides a kind of test equipment of ultrasonic water meter transducer, please refer to Figure 1 、 Figure 2 , mainly including the test pipeline 1 for water running, host computer 2 and erecting multiple water meters 5 on test pipeline 1, test pipeline 1 is located at the erecting position of multiple water meters 5 Two ends are respectively provided with valve, and the valve is electrically connected with host computer 2;Host computer 2 includes water running test module, zero drift test module and data switching module, and multiple water meters 5 are electrically connected with water running test module or zero drift test module by data switching module, so that host computer 2 receives water running test data and zero drift test data of water meter 5 in turn.

[0024] In the present application, the water meters 5 to be tested are arranged on the test pipeline 1, and different test conditions required for the water running test and the zero drift test are realized by adjusting the water running state in the test pipeline 1, wherein the test condition for the water running test is full-pipeline water running, and the test condition for the zero drift test is full-pipeline static water.

[0025] For example, the host computer 2 controls the two valves to be opened at the same time, the water supply device supplies water into the test pipeline 1 to realize full-pipeline water running, and at this time, the water running test can be performed; after the water running test is completed, the water supply is maintained, the host computer 2 controls the two valves to be closed at the same time, and full-pipeline static water is realized, and at this time, the zero drift test can be performed.

[0026] In a specific embodiment, the valves can specifically include a first control valve 11 and a second control valve 12, the first control valve 11 is arranged on the test pipeline 1 before the plurality of water meters 5, and the second control valve 12 is arranged on the test pipeline 1 after the plurality of water meters 5.

[0027] The two control valves are arranged at two ends of the water meter arrangement area, so that when the two control valves are closed, the test pipeline 1 in the water meter arrangement area can be ensured to be in the full-pipeline static water state. It is feasible to close the second control valve 12 first after the water running test is completed, while maintaining the water supply, and then close the first control valve 11, to ensure that the test pipeline 1 in the water meter arrangement area is in the full-pipeline static water state.

[0028] In actual application of the test device, when the zero drift test is performed, it is required to ensure that the test pipeline 1 in the water meter arrangement area is in the full-pipeline static water state, and the test pipeline 1 outside the two control valves is not required; when the water running test is performed, it is required to ensure that the test pipeline 1 in the water meter arrangement area is in the full-pipeline water running state.

[0029] In the embodiment of the present application, a pressure sensor 21 can be arranged on the test pipeline 1, the pressure sensor 21 is used to detect the water pressure in the test pipeline 1, so as to determine whether the water running state in the test pipeline 1 is full-pipeline static water or full-pipeline static water, and the pressure sensor 21 can be electrically connected with the host computer 2, so that the host computer 2 can control the supply amount of the water supply device or control the opening / closing of the valve according to the detection result.

[0030] For example, when the water pressure in the test pipeline 1 is insufficient, the test condition of full-pipeline water running cannot be reached, and the supply amount of the water supply device can be increased; when the water pressure in the test pipeline 1 meets the standard, the test condition of full-pipeline water running is reached, and the supply amount can be maintained to implement the water running test.

[0031] For example, when the zero drift test needs to be performed after the water running test is completed, the two control valves can be directly closed by the host computer 2, and the full pipe water running state is directly switched to the full pipe static water state. Meanwhile, the water supply device should be closed. At this time, the water pressure is stable at a specific value, and whether the full pipe static water state is achieved can be determined by the water pressure detection, so as to perform the zero drift test in the full pipe static water state and obtain accurate test data.

[0032] In the embodiments of the present application, the water running test and the zero drift test should be in the same or similar temperature range during the test process of the same water meter 5. A temperature sensor 22 can be arranged on the test pipeline 1. The temperature sensor 22 is used to detect the water temperature, so that the two test variables are single.

[0033] For example, the temperature sensor 22 can be arranged downstream of the water meter 5, i.e., downstream of the water meter installation area. The temperature sensor 22 can be electrically connected with the host computer 2. The host computer 2 can determine whether to perform the test according to the detection result.

[0034] In order to ensure the continuous performance of the water running test and the zero drift test, the water temperature can be controlled to make the water temperature in the whole test process consistent.

[0035] In the embodiments of the present application, a heater 4 can be arranged on the test pipeline 1. The heater 4 is used to heat the water in the test pipeline 1. The heater 4 is electrically connected with the host computer 2. The host computer 2 is used to adjust the heating power of the heater 4 according to the detection result of the temperature sensor 22, so that the water temperature in the test process is consistent, and the test variable is single.

[0036] It can be understood that, since the zero drift test is full pipe static water, and the zero drift test needs a period of time for data sampling, the decrease of the water temperature during this process can be ignored. If the temperature difference between the external environment temperature and the water temperature is large, a constant temperature device can be arranged outside to ensure that the influence of the external environment on the water temperature is minimized.

[0037] During the water running test, the water running speed should not be too fast to prevent exceeding the power upper limit of the heater 4. The supply amount of the water supply device in a unit time can be limited based on the power upper limit of the heater 4.

[0038] In the present application, the water supply device can be a water pump 3. The water pump 3 is arranged at the water inlet of the test pipeline 1. The water pump 3 is electrically connected with the host computer 2. The host computer 2 is used to adjust the supply amount of the water pump 3 and the opening / closing of the valve according to the detection result of the pressure sensor 21, so that the water running state in the test pipeline 1 meets the test conditions of the water running test or the zero drift test.

[0039] In a feasible embodiment, a frequency converter can be arranged between the host computer 2 and the water pump 3. The host computer 2 adjusts the supply amount of the water pump 3 through the frequency converter.

[0040] In the present application, the test pipeline 1 is in a full-pipe water running state during the water running test, and a large amount of water is needed, which can be recycled, so the water outlet and inlet of the test pipeline 1 can be connected or connected through a water storage device, so that the water can be recycled during the water running test. Of course, the water quality should be detected to meet the standard to avoid the influence of the water quality on the test results.

[0041] In the embodiment of the present application, the test pipeline 1 can be erected on the test platform, and the water running test and zero drift test can be performed on the test platform, and the water inlet end and the water outlet end of the test pipeline 1 can be extended downward below the test platform to establish a connection with the water supply device, the water storage device and the like, and the heater 4 can also be arranged below the test platform, and the upper computer 2 can be built based on the test platform, and the main structure can be located below the test platform, and a display can be arranged on the test platform to display the test results of the water running test module and the zero drift test module and the operation state of the data switching module, wherein the operation state of the data switching module is the water running test and the zero drift test.

[0042] The water running test module is used for water running test, and the parameters of the water meter 5 are corrected according to the test data under the full-pipe water running state, so that the water meter 5 can accurately measure and detect the water quantity; the zero drift test module is used for zero drift test, and the water meter 5 after parameter correction is used for zero point calculation to obtain the zero drift value of the water meter 5 under the full-pipe static water state, so that the water meter 5 can measure the water quantity.

[0043] In the present application, the data switching module can be realized by a software program, and when the water running test is completed, the data transmission object is switched to the zero drift test module, and after the zero drift test is completed, the default data transmission object is the water running test module.

[0044] Of course, the data switching module can also be a hardware switch, which is connected with the water running test module by default, and when the water running test is completed, the state is changed to be connected with the zero drift test module, and when the zero drift test is completed, the reset is performed.

[0045] In the embodiment of the present application, the water meter erection area of the test pipeline 1 can be a straight pipe type, as shown in Figure 1 The water meter erection area of the test pipeline 1 can also be in the form of "U", specifically, the test pipeline 1 in the water meter erection area includes two parallel straight pipe sections and an arc pipe section for connecting the two straight pipes, and a plurality of water meters 5 are arranged on the two parallel straight pipe sections respectively, and the test of the plurality of water meters 5 is performed simultaneously.
