There is a rotor flowmeter, the original steel rotor, and now use the same shape of plastic rotor instead, will the same scale of the flow will increase or decrease?
The plastic density is small, the quality is smaller than the steel, under the same scale, the flow is reduced.
The shape of the plastic rotor is smaller than that of the steel rotor, and when the flow of the same flow passes, the plastic rotor rises at a higher height than the steel rotor, so the scale needs to be corrected upwards
