We have a flare gas measurement application on a 12" line for a gas plant. The composition of the gas in not constant so we have phased out thermal mass as well as DP ones. We have decided to use ultrasonic.
SICK has a model which is insertion from one side only, model FLOWSIC100 Flare. It is attractive as it takes little real estate and access platform is required on one side only.
I am not sure about the performance of such an insertion and do not want to solely rely on vendor's word.
Appreciate if anybody could share their experience with me.
