Flowmeters for cryogenic applications often fail in service. Turbine flowmeters in particular fail due to very high speeds encountered during chill-down operations. Very cold, very high-velocity gas causes the turbine to spin uncontrollably, which quickly degrades bearings. Those flowmeters that do not fail are often unreliable, degrading their effectiveness as instrumentation to monitor and control cryogenic propellant loading.
