1. Depends on your set up. Technically the water flows continuously between the sump and display, so only one should be required if you decide to install one at all. Once water stops flowing, you've opened the 'circuit' so to speak. But that usually happens during a power outage or when you turn off the return pump so no electricity is present.

2. You can make your own, but insulating it with plastic will defeat the purpose. You'll need to get hold of a non corroding metal such as stainless steel or better yet titanium.
