What flowmeter is used to measure the flow rate of pure water?
The rotor flowmeter is simple and cheap, but the measurement accuracy is poor. The mass flowmeter is more expensive. Generally, vortex flowmeter can be used better. Only when the working conditions are as accurate as possible and in a wide range of flow can the flow measurement error be far away from the design point. Or specific circumstances, select it. There is no best, only the most appropriate. Ha-ha。
As for the rotor (including rotor table), flowmeter, vortex flowmeter or mass flow meter which is better, this needs to be selected according to specific circumstances.
First of all need to explain is: for pure water flowmeter can not use electromagnetic flowmeter, this is because the conductivity of pure water is very low, electromagnetic flowmeter is unable to work properly, of course, more uncertain.
