Automated Transfer Function Generator

When designing or analyzing electrical systems, it is important to understand the relationship between input and output. Power conversion occurs in a “black box,” and transfer functions can be used to provide a better understanding of the processes occurring in this black box. Although they provide a...

Overspeed Protection for Turbine Flowmeters in Cryogenic Applications

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....
