As a kind of high precision measuring tool, the air momentum meter is widely used in the field of industrial measurement. However, when faced with a large roughness of the workpiece, the traditional method of using the gas meter may require some adjustment and optimization.

First of all, we need to make it clear that the air momentum meter measures by blowing high-pressure air over the workpiece surface, so the roughness of the workpiece surface will directly affect the measurement accuracy. In order to minimize the impact of roughness on measurement, we can take the following measures:

Pretreatment of the workpiece: Before measurement, the workpiece is pre-treated as necessary, such as grinding, polishing, etc., to reduce its surface roughness. This can not only improve the measurement accuracy, but also extend the service life of the gas meter.

Select the right measuring head: According to the characteristics of the workpiece and measurement requirements, select the right measuring head. For the workpiece with larger roughness, a measuring head with a larger measuring range can be selected to improve the stability and accuracy of the measurement.

Adjust the measuring parameters: according to the actual situation of the workpiece, adjust the measuring parameters of the gas momentum meter, such as measuring speed, pressure, etc. By optimizing these parameters, the influence of roughness on measurement can be reduced and the accuracy and stability of measurement can be improved.

Multiple measurement averaging: Because the surface of the workpiece with larger roughness may have large fluctuations and irregularity, multiple measurement and averaging is an effective method to improve the measurement accuracy.

Pay attention to maintenance and maintenance: When using the gas meter, it is necessary to pay attention to its maintenance and maintenance. Clean the measuring head and air circuit regularly to check whether the seals and connectors are in good condition to ensure the accuracy and reliability of the measurement.

Through the above measures, we can effectively use the gas momentum meter to measure the workpiece with larger roughness, improve the accuracy and stability of the measurement.
