Coriolis type flow meter vs Vortex flow meter
Coriolis type flow meter vs Vortex flow meter
(OP)
Dear
I would like to know which Coriolis or Vortex flow meter is better for the steam fluid and why is the reason for
that.
As I know vortex shedding flow meter is wildely used type of oscillaotry flow meter. The frequency of the vortex is directly proportional to the velocity of the fluid flowing through the flow meter. And, it is becoming increasing more popular for measuring the flow of steam, liquid and gases.
Thank you very much for your kindly help.

This used a shuttling disc to detect shedding.
Now you have had for a long time Yokagawa at the top of the tree and more recently Emerson.

Endress+Hauser is another good manufacturer. I would also check for the noise reduction (due to vibration) techniques while going for a vortex.
I am a bit confused by the last sentence in your second paragraph. That is rather marketing than technical.

Another factor is the low flow cutoff with a vortex meter. The accuracy for a coriolis meter is normally stated in percentage of flow rate compared with percentage of the full span with many other technologies. With a orifice/dp flow meter the accuracy drops off toward with low flow. A vortex meter stops working with low flow.

Steam is easier to measure than many fluids.

With steam, keep it simple.
