Heat tracing for glycol

[helpyou]

Hi guys ,

Can someone tell me why we use heat tracing for glycol used in impulse line in level measurement? Does the state of the glycol change with the process pressure of the vessel where level is measured? Thank you

Apparently you are dealing with ethylene-glycol not antifreeze solutions, so you need to specify temperature pressure, and purity of your fluid.
