Temperature Measurement on LNG lines
Temperature Measurement on LNG lines
(OP)
I am looking for information on the installation details of an RTD surface mount pad to measure temperature on crogenic lines. As the gas is liquid the obvious choice would be on the bottom of the pipe but someone has told me there could be the possibility of condensation running down the pipe therefore mounting on the side would be better, can anyone advise?

Are you wanting to measure the temperature of the LNG, or what?
The temperature of the outside of the pipe may have little to do with the actual temperature of the LNG

A thermowell is the best way to do it but since these 'cooldown' monitoring temp sensors need to be installed every 50 metres you can imagine the cost!
The fiber optic method is quite costly and difficult to install as most of these LNG lines come pre-insulated before they are even installed.
The information on the orientation of the sensors was useful i.e. 4:30 or 7:30.
