As a precision part dimension measuring tool, the pneumatic meter can measure not only the length, but also the shape and size, including the inner diameter of some special objects, the spacing of small holes and the width of these slits. When the measurement accuracy of the air momentum meter is not accurate, after excluding some conventional influencing factors, the following factors should also be paid attention to:
    1Changes in the environment of the workpiece will affect the accuracy.The gas gauge also has certain requirements for the specific physical form of the workpiece. If the workpiece surface itself is the result of roughness, there will be obvious marks after processing, so these sawdust or other oil stains will lead to data bias.
    2In the process of using the gas momentum meter, pay attention to the influence of the coolant.If there is dust or other impurities, it is likely to cause accuracy errors. We should try to avoid these cleaning problems in our work.
    3Too much vibration will also affect the accuracy.Because the air momentum meter will inevitably produce vibration during the measurement process, but small vibration is acceptable. However, if there are many other large equipment in the measurement environment, such as punches, air compressors and other heavy equipment, it is easy to affect the measurement. Pay attention to the difference between the vibration of the mechanical equipment itself and the vibration caused by other materials outside. The two vibrations are different. To be sure, accuracy in the later stages will also be affected.

    4The quality of compressed air also affects the accuracy of the gas gauge.Water and oil substances should be prevented in the measurement, which is easy to cause gas interruption and have an adverse effect on the measurement. Therefore, if you find relevant impurities, learn to clean up in time.
