Air cooling fin for flow meter
Sometimes, flow meter might be used to measure high temperature liquid, such as hot water.
At this moment, it will be better if the flow meter could have air cooling fin on its neck.
This fin is good at protecting flow meter converter when it's working.
And based on the temperature, it could be produced with suitable length.
