We are designing this meter which will monitor house hold consumption. The problem that I am facing right now for days and weeks now, how do I make the meter water proof. I have tried everything but could not find an exact solution.
I tried looked for already made enclosure box that we can use they are a bit expensive as we need bigger enclosure (>240mm) + I dont know who the whole can be air tight when we passing electrical wire through it.
We are also exploring molding option but I dont know what exactly I need. For do I place conducting strips in the mould already which will be my connection point from inside and outside? Or do I drill holes in it and later cover it with some special connectors. Any help is appreciated.
I cam across these types of enclosure (highlighting the joint), should I be using something similar. How do they provide water proofing. What is recommended technique to create water and dust proof isolation for a meter?
Included is my meter design where I need help regarding water proofing.
