Subsea Coriolis Applications 2

[Tom64]

Has anyone got experience of using a Coriolis meter to measure flow of chemical subsea?
Have experience of Venturi's and such but particular chemical needs to be measured by Coriolis.

Needs to be?
You need mass flow? If this is a chemical for which you know the quality, i.e. density Vs Temperature, why not a volumetric meter?
Are none of the high pressure sub-sea PD meters any good? (e.g. Flow Technlogy Inc.)
Just curious.

The polymer solution is susceptible to shearing which damages the polymer. PD meters were reviewed and were not ideal due to shearing risks associated with them.

Understood.
There is an article in TheEengineer from TUV NEL which may therefore be of relevance to you:

They would have to prove the meter under water to compensate for the conditions. Then you'd have to develop a sealing system for the elctronics.

Coriolis flow splits the flow into two smaller tubes, so some shearing occurs there. In some designs the tubes are a full horseshoe in shape, others are 'almost' straight (e.g. Foxboro).

If we learn from our mistakes I'm getting a great education!
