Hi to all.

I need advice about the measurement of carbon dioxide CO2. This medium has two states: gas or liquid. During pumping carbon dioxide from the tank medium goes from liquid to gaseous. Is it possible measure the first liquid and then gas with one Micromotion?

Hi Wladimir,

I do not know which industry you're in, but in the beverage industry the measurement of CO2 is very common and usually the meters are installed after the evaporator or in any point far away from the tank so the CO2 is only in the gas phase.
Here in Brazil we have several references in this application; usually to totalize the consume of CO2 or for controlling the injection of gas into the beverage (carbonation machine).

Any specific application are you looking for?

Best regards,

Coriolis meters will measure the mass of whatever is flowing through it. The p[otential problem is when the meter is initially set up with the flow parameters. Hig and low cut offs will be significantly different for gas and liquid. Any way to maintain a constant temperature and pressure to maintain a liquid or gaseous state?

Hach Manufacturers a CO2 Analyzer for the Beverage industry. I'm not sure on the gas / liquid requirement.
