Digital Windmeter have many advantages, the following are some of the more important:
1. Small size, little interference to the flow field;
2. Wide range of application. It can be used not only for gas but also for liquid, and can be used in subsonic, transonic and supersonic flow of gas;
3. High measurement accuracy and good repeatability. The disadvantage of the hot wire anemometer is that the probe interferes with the flow field to a certain extent, and the hot wire is easy to break.
4. In addition to measuring the average speed, it can also measure the pulsation value and turbulent amount; in addition to measuring the movement in one direction, it can also measure the speed components in multiple directions at the same time.
