FPE liner is one type of important material for electromagnetic flow meter.

It's similar as PTFE liner on anit-corrosion.

But it also have some advantagement.

1. It could work on negative pressure.

Sometimes, pump may produce negative pressure, but PTFE liner or Neoprene liner all could not work on this condition.

FEP liner is produced via special technology, and it could work on negative pressure.

2. FEP liner could work on much lower or high temperature.

It could resist -40℃ temperature.

In Russia, Canada, or other cold cunntries, this is a very important factor for flow meter works outdoor.
