How would you hook up a pressure indicator or...?

Question

pressure transmitter to a cryogenic liquid point (liquid nitrogen)?

What additional steps would you have to take in order to take measurements (flow, pressure, etc.) on a cryogenic process?

Answer 1

Just make sure that the transmitter is rated for the temperature of the liquid/gas you are measuring. Like this one:

Also... make sure the connection orifice is also rated for low temperatures, mechanically.
