The vortices generated by the tangential entry of the evaporator circulation pipe cause unstable readings on the differential pressure transmitter
Thread Content
As the title suggests, when designing an evaporator separation chamber, the circulation pipe enters the chamber tangentially, which creates vortices within the chamber and as a result leads to unstable readings from the differential pressure transmitter in that chamber. Do any of you have any good solutions to this issue of unstable differential pressure transmitter readings?

It is recommended to install a protective cover at each pressure tapping point of the transmitter inside the equipment; the cover should be open at the top and bottom while closed on all other sides, so as to reduce the impact of materials. The diagram shows schematic illustrations of square and curved protective covers.

Thank you. I had thought of this method as well, but there are inorganic salts at the bottom of the separation chamber. So doing as you suggested can resolve the issue of unstable instrument readings, but it will affect the flow pattern of the crystals. Therefore, I thought of adding a cross shape inside to reduce vortices, but I’m not sure if that will work
Can we replace the differential pressure transmitter with a float-type level gauge? Are there crystals?
I’ve thought about it, but I’m not sure what the actual outcome will be
Currently, most have large surface fluctuations, so it is set this way.
Add a cross-shaped baffle just below the liquid surface?
