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.'

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