Selection issues for steam vortex flowmeters
Thread Content
I would like to ask everyone whether it is appropriate to use an insert-type vortex flow meter for the DN300 steam main pipeline. When reviewing the information, I saw that it is not recommended to use the insert type, as its accuracy can be affected by the installation conditions ； Moreover, vortex flowmeters with a diameter of DN300 or larger seem to be not recommended for use. I’ve only been working with instruments for a short time; most of what I know is theoretical. I would appreciate any guidance from those with more experience!
Why use the plug-in type? Aren’t flanges better?
I haven’t used insert-type vortex flow meters, so it’s hard to give an evaluation. It’s fine to use a balanced flow meter or a delta bar here, but temperature and pressure compensation also need to be taken into account.
The main drawback is their high price; generally, differential pressure orifice plate flow meters are more commonly used for sizes above DN300, while those with higher precision include balanced and Venturi types
