However, these measurement methods have obvious disadvantages, and are easily interfered by external electromagnetic interference, or measurement errors are caused by the accumulated adsorption of the permanent magnet to impurities in water, or the measurement errors are manually utilized, neglected and counted. In order to solve the problems, the nonmagnetic water meter has the advantages of high metering precision, no magnetism, no impurity adsorption, no man-made interference and the like, and the nonmagnetic water meter is formed by adding a lifting semicircular metal pointer on the basis of the traditional mechanical water meter.

The driver 121 can be an electronic device such as a direct current motor which generates driving torque, the glass sheet 14 can be tempered glass or organic glass, and because glass made of various materials is used as a pressure-bearing element of the non-magnetic water meter on the market at present, and the requirement of the non-magnetic water meter on the detection distance is strict, the organic glass is applied to the water meter accordingly. The organic glass has the advantages of high strength and small volume, and the thickness of the organic glass can be lower than that of toughened glass under the same static pressure condition, so that the distance between the metal pointer and the nonmagnetic module can be shortened; however, organic glass is expensive, the time for applying the organic glass to a water meter is short, and in addition, the organic glass on the market is made of various materials, even if the organic glass is made of one material, the adopted types are different, the dielectric coefficients of various kinds of glass are also different, and certain influence can be generated on non-magnetic signals.

Illustratively, after the non-magnetic sensor 13, the glass sheet 14 and the sensor wheel 123 are placed at the planning position, the position is adjusted by the distance adjusting mechanism to find the optimal distance. The effect of these elements on the sensing ability can be tested by replacing the different sensed wheels 123, glass sheets 14 and non-magnetic sensors.

Therefore, the distance adjusting mechanism 15 is arranged on the nonmagnetic metering and testing device 10, the distance between the nonmagnetic sensor 13, the glass sheet 14 and the induction wheel 123 can be flexibly adjusted, the rotatable supporting plate is arranged on the connecting part 151, the phenomenon that the induction wheel, the glass or the nonmagnetic sensor cannot be taken out due to space limitation is avoided, the test materials are conveniently replaced, and the detection efficiency is improved.

Optionally, an electronic scale and a limit groove are disposed on the connection portion 151, the electronic scale is used for reading positions of the first supporting plate 153 and the second supporting plate 154, and the limit groove is used for limiting horizontal positions of the first supporting plate 153 and the second supporting plate 154.

It can be seen that the electronic scale is disposed on the connecting portion 151 to facilitate reading the positions of the first supporting plate 153 and the second supporting plate 154 and calculating the relative distance, and the limiting groove disposed on the connecting portion 151 can prevent the magnetic sensor 13 and the glass sheet 14 from being out of the vertical sensing range due to the excessive rotation angle of the first supporting plate 153 or the second supporting plate 154.

Optionally, the rotating speed mechanism further includes a speed regulating switch 16 and a display 17, the speed regulating switch 16 is used for regulating the rotating speed of the driver 121, and the display 17 is used for displaying the rotating speed of the driver 121.

The main control board 19 can also read the instruction of the terminal, and realize nonmagnetic measurement reliability evaluation, nonmagnetic measurement unit device evaluation and batch nonmagnetic sensor qualification evaluation according to the preset detection flow.

In addition, the existing mechanism is single testing equipment, and only a single machine can simulate and test the proper distance range of the non-magnetic sensor and the semimetal induction wheel. The application can also increase a communication interface for connecting the non-magnetic metering test device with the server, can upload a test conclusion to a production wireless MESH (MESH) system, is convenient for follow-up tracking of production process detection data, and assists in solving the production problem. When the device is used for incoming material inspection, incoming material inspection records can be conveniently recorded, and the problem of manual data recording is reduced.

Therefore, the efficiency of the nonmagnetic metering test can be improved by arranging the main control board 19 on the nonmagnetic metering test device 10, sending the test result to the terminal and carrying out the detection step according to the terminal instruction.

Further, the nonmagnetic metering and testing device 10 provided by the application can also be used for detecting whether nonmagnetic sensors are qualified or not during batch production, and reducing the risk of bad rework after the online.

Optionally, be provided with Universal Asynchronous Receiver Transmitter (Universal Asynchronous Receiver Transmitter, UART) interface (not shown in the figure) on the main control board 19, the main control board passes through no magnetism induction intensity is read to the UART interface, based on no magnetism induction intensity judges no magnetism sensor with the interval of inducted wheel is in the effective interval scope.

The existing device can only compare the rotating speed value sensed by the non-magnetic sensor and the rotating speed reading of the metering mechanism at different intervals. The UART interface which is used for reading the induction intensity value of the non-magnetic sensor is not provided with a serial port, so that only a mechanical comparison rotating speed value can obtain a proper design interval value of the distance between the non-magnetic sensor and the semi-metal pointer, and the interval value is difficult to actually measure in the actual production process after the whole meter is assembled.

In the scheme provided by the application, a pulse metering method is adopted for metering data. The comparison of the number of rotation turns of the induction wheel 123 and the non-magnetic induction metering pulse value can reduce the verification error to +/-1 pulse interval, and better meets the requirement of electromechanical conversion error +/-1 pulse required by water gauge evaluation and detection.

After the nonmagnetic sensor 13, the induction wheel 123 and the glass sheet 14 to be tested are placed in the nonmagnetic metering and testing device 10, the server controls the rotating speed mechanism 12 to rotate within a preset flow speed range, the difference between nonmagnetic metering and synchronous wheel metering is compared, if the deviation is smaller than +/-1, the distance between the first supporting plate 153 and the second supporting plate 154 is increased, the test is continued until the two metering differences are larger than +/-1, which indicates that nonmagnetic metering is inaccurate, and at this time, the distance between the induction wheel 123 and the nonmagnetic sensor and the signal intensity value of the nonmagnetic module are automatically recorded.

According to the recorded data, the effective metering distance and the signal intensity range of the nonmagnetic metering under the condition of the combination of the nonmagnetic sensor 13, the inductive wheel 123 and the glass sheet 14 can be effectively evaluated. According to the range and the tolerance of the system structure design, whether the combination without the magnetic measurement has enough design allowance under the current combination can be effectively evaluated, and whether the requirement of mass production is met.
