Coriolis flowmeter that measures two-phase flow

Coriolis flowmeter that measures two-phase flow

Coriolis flowmeter that measures two-phase flow

(OP)
Hi all,

Anybody experience with this meter? See below:

Foxboro has introduced a mass flow transmitter with digital technology that allows standard Coriolis flow meters to continue operating during two-phase flow, which happens when air is introduced into the liquid flow stream.

The traditional problem has been the impact of entrained air, which can interrupt measurement for tens of seconds and stall or shutdown the flow tube.

... CFT50 demonstrations at the ISA conference. The flow tube was started up from empty and then later, flowing with water, compressed air was introduced. The air started from a small amount and was increased to 60%. The tube continued accurately measuring the flow. The speed of response was in 'tens of milliseconds.'

Thanks for sharing knowledge,

Does Invensys mention which phases?  Perhaps it is liquid and solid.  Perhaps I should visit their web site.

John,

Since the described demonstration is with an air/water system, 2-phase must mean gas/liquid.

RE: Coriolis flowmeter that measures two-phase flow

We have seen the demonstration and we think it will work in our application as well but we have not tested one on our site yet. We plan to test one in near future. But it looks promissing.
