The difference between flow sensor type 235 and type 200 is the version of the case. The flow sensor type 235 is based on the Kármán vortex street. You can choose between various versions as integrated temperature measurement. This flow sensor without moving parts is insensitive to pollution and persuade by very few loss of pressure and a very high accuracy.
