For supercritical CO2 transport, what type of flow meter should be used?
Thread Content
Today I saw long-distance CO2 pipelines that use supercritical transport; I’m wondering what type of flow meter would be suitable for such fluids
The question is too vague; I can’t understand it
The mass flow meter works well. We produce urea, and initially we used differential pressure transmitters to measure carbon dioxide, but those weren’t very effective; later on, a mass flow meter was added……
If the requirements aren’t very high, vortex flow meters, target flow meters, or orifice plates can be used. For highly accurate measurements, mass flow meters can be employed; however, they are expensive. Domestic mass flow meters aren’t cheap either and aren’t accurate. The E+H models I’ve used have worked quite well
Supercritical carbon dioxide has a high pressure, but it has excellent fluidity and low viscosity. Vortex flowmeters can be used to measure flow rates, and they are quite suitable for high-pressure applications. If high accuracy in measurement is required, a mass flow meter can be chosen, but it results in greater pressure loss and is prone to signal disturbances.
Bore, temperature, pressure, and flow – none of these four factors are particularly important, making it difficult to make a choice. But commonly used ones include vortex street, target, and thermal mass flow meters, all of which are suitable.
