Cryogenics is the study of low temperatures.
The turbine flow meter is a very good choice of measurement due to the material and its ability to hold up to cryogenic temperatures and to accurately repeat at any flow rate.
The turbine creates minimal pressure drop or flow constriction in a catastrophic failure.
Flows can be maintained under any circumstance.
The turbine is also the most accurate and durable for use in a transport due to vibration resistance.
