Method and apparatus for measuring cryogenic flow

John Arthur Urbahn, +1 more
TLDR
In this paper, a method for calculating the mass flow rate of a cryogenic fluid within a flow tube is proposed, which involves positioning a sensor within a stream of cryogenic liquid flowing through the flow tube.
Abstract: 
A method for calculating a mass flow rate of a cryogenic fluid within a flow tube includes positioning a sensor within a stream of cryogenic fluid flowing through the flow tube. The sensor is operatively coupled to a strain gauge. A difference between a dynamic pressure in the fluid stream and a static pressure in the fluid stream is measured and the mass flow rate of the cryogenic fluid within the flow tube is calculated.
