Need cryogenic 100% mechanical flow meter

[textileng]

Hello everyone,

I need to find a completely mechanical cryogenic flow meter for one of my customers. The operating temperature is as low as -250F. I appreciate any ideas.

before seeking any metering information, it is essential to know the fluid, fluid properties, operating parameters (p, t, vis, etc.), flow range (normal, min, max, upset), and desired meter output.

once this data is known, you can start your search/investigation. otherwise, confusion or chaos reigns.

good luck!
