Applications/Examples of results
■Measurement Principle: Vane Type The rotation speed of the rotor, which rotates at a speed proportional to the fluid velocity, is counted by a proximity switch to calculate the flow rate. The rotor is made with a weight of 0.3 to 0.7g, allowing it to respond to weak wind speeds. The bearings and other components are manufactured using a special system that minimizes the effects of friction. Additionally, it is capable of measuring the flow rate of not only gases but also water.
