Questions about jacketed rotameters
Thread Content
One of the requirements for selecting metal rotor flowmeters as specified in the standards is as follows: The selection of jacketed metal tube rotor flowmeters shall comply with the following rules: a) When the medium to be measured is prone to condensation, crystallization, or vaporization, a jacketed metal tube rotor flowmeter can be used, with a heating or cooling medium circulated through the jacket； b) The maximum diameter of a jacketed metal tube rotameter should be DN80. How is heating or cooling achieved with this jacketed connection method? Are there any relevant photos from the scene? The projects I worked on previously mostly used flange connections, and the steam tracing was implemented in a similar manner to pipeline insulation, with the secondary instruments exposed outside.
We have used jacketed rotors with steam flowing through them; in my opinion, this is similar to using a jacketed valve – I’m not sure if that’s correct.
Process medium flows inside, while hot water, steam, or coolant flows outside.
